Would global warming reduce sorghum yields?

While not terribly well-known around Western dinner tables, sorghum is actually an important crop that feeds about half a billion people worldwide. It can be used for almost anything that other grain crops can be used for.  It can be used to make syrup, to make bread and as livestock feed.

So it is mildly disappointing and quite surprising to hear that higher temperatures would be harmful to it.  It is normally known as a highly heat-resistant crop.  So what is going on in the report below?

There are several things that could be noted.  The simplest is that cultivars suitable for one area may not be suitable for others.  The authors take cultivars currently used in Kansas and show that they are not suitable for localities where the temperatures are higher than in Kansas.

That should surprise no-one.  Farmers optimize the cultivars they use to produce maximum output for their particular area.  And there are cultivars suitable for higher tempertures than are usual in Kansas.  All that the authors have shown is that if temperatures change your cultivars would have to change too.  And sorghum is particularly suitable for that.  It is already grown im many hot areas of Africa and India.

I could go on but I think it is already clear enough that the report below is a false alarm


Disaggregating sorghum yield reductions under warming scenarios exposes narrow genetic diversity in US breeding programs

Jesse Tacka et al.

Significance

Sorghum’s ability to withstand harsh environmental conditions has placed it in the forefront of discussions regarding potential adaptation paths under climate change. While sorghum may indeed be a good candidate to substitute for other major row crops as warming materializes in areas where it has not traditionally been grown, an equally important consideration is whether its production can be sustained in the warmer areas where it has traditionally been grown. Our findings suggest limited potential for climate change adaption using currently available cultivars but do not preclude the overall role of genetic innovation and enhanced decision making in adapting to climate change. Successful adaptation could perhaps best be facilitated by expanding the scope of genetic stock within sorghum breeding programs.

Abstract

Historical adaptation of sorghum production to arid and semiarid conditions has provided promise regarding its sustained productivity under future warming scenarios. Using Kansas field-trial sorghum data collected from 1985 to 2014 and spanning 408 hybrid cultivars, we show that sorghum productivity under increasing warming scenarios breaks down. Through extensive regression modeling, we identify a temperature threshold of 33 °C, beyond which yields start to decline. We show that this decline is robust across both field-trial and on-farm data. Moderate and higher warming scenarios of 2 °C and 4 °C resulted in roughly 17% and 44% yield reductions, respectively. The average reduction across warming scenarios from 1 to 5 °C is 10% per degree Celsius. Breeding efforts over the last few decades have developed high-yielding cultivars with considerable variability in heat resilience, but even the most tolerant cultivars did not offer much resilience to warming temperatures. This outcome points to two concerns regarding adaption to global warming, the first being that adaptation will not be as simple as producers’ switching among currently available cultivars and the second being that there is currently narrow genetic diversity for heat resilience in US breeding programs. Using observed flowering dates and disaggregating heat-stress impacts, both pre- and postflowering stages were identified to be equally important for overall yields. These findings suggest the adaptation potential for sorghum under climate change would be greatly facilitated by introducing wider genetic diversity for heat resilience into ongoing breeding programs, and that there should be additional efforts to improve resilience during the preflowering phase.

Sea ice a ‘handbrake on global warming’

Something else left out of the global warming "models"

Melting sea ice could help cool the planet by flooding the atmosphere with particles that deflect sunlight.

Australian research suggests climate modellers have under­estimated a natural “thermostat” that helps alleviate the rise in temperatures: immense quantities of reflective compounds, emitted by marine microbes, that act like a handbrake on global warming.

The study, published by the American Meteorological Society, suggests an overlooked source of these so-called aerosols — algae living in ice — could jam the handbrake on even harder. Lead author Albert Gabric said with the Arctic expected to see ice-free summers within a decade, far more of the aerosols would be emitted.

“Whether that can slow the rate of warming of the Arctic is the trillion-dollar question,” said Dr Gabric, a marine biogeo­chemist with Griffith University in Brisbane.

Climate scientists have long known that aerosols help mitigate global warming by bouncing sunrays back into space, and by altering clouds to make them more reflective. Experts believe half of the ­potential warming from greenhouse gases may be offset in this way.

Much research has focused on aerosols produced artificially, through the burning of fossil fuels and vegetation. Scientists worry that if China switched to renewable sources of energy overnight, it could trigger a massive surge in warming.

Aerosols are also produced naturally by volcanoes — such as the 1991 eruption of Mount Pinatubo in The Philippines, which is credited with cutting global temperatures by about 0.5C for two years — and by marine ecosystems.

Algae known as “phytoplankton” are a major contributor, with increasingly massive blooms of these marine creatures emerging in the warming Arctic waters.

The new study analysed terabytes of satellite data to track atmos­pheric aerosol concen­trations. For the first time, it identified sea ice as a “very strong source” of the airborne particles.

Dr Gabric said “ice algae” had evolved to tolerate the subzero temperatures of sea ice and the water that formed it. They used a compound called dimethyl sulfide as an “antifreeze” to survive the chill. “When the sea ice melts during spring, these algae don’t need that protection any more. They expel these compounds, which are degassed to the atmosphere and converted into sulfate aerosols very similar to what you get from burning sulphur-containing coal.

“This happens every year as the sea ice melts. The difference in recent decades is that the ice is melting a lot earlier. We now think that within 10 years there won’t be any ice in the Arctic during summer.”

He said the process had “absolutely not” been factored into the Intergovernmental Panel on Climate Change models of global warming. “The whole aerosol question and its relationship to warming is the biggest uncertainty to projecting what’s going to happen this century.

“This is a new area of ­research, primarily because people can’t get up there and measure it very easily. You need an ice­breaker and a big gun to shoot any polar bears that might want to eat you,” he said.

Fair trade for thee, but not for me/b>

Imagine what a Tesla or wind turbine would cost if the Left followed its own “principles”

Paul Driessen

“Nobody wants to buy something that was made by exploiting someone else,” Ben & Jerry’s and Fair Trade co-founder Jerry Greenfield likes to tell us. Let’s hope he doesn’t drive an electric vehicle, doesn’t use a laptop or cell phone, and doesn’t rely on wind or solar power.

We’re constantly confronted with slogans and lectures about fair trade, human rights, sustainability, environmental and social justice, little people versus Big Corporations. Most of these subjective terms reflect perspectives and agendas of the political left, and are intended to advance those worldviews and stifle any discussion about them. But most of their self-avowed adherents never look beneath the surface of their own purchases. Indeed, they would have no standards at all if they didn’t have double standards.

Just imagine what a $35,000 to $150,000 electric vehicle would cost if it were built using “fair trade” metals. How expensive already pricey wind and solar electricity would be if manufacturers had to follow fair trade standards, pay the full human and environmental costs associated with components, and pay workers the source-country equivalents of “Fight For $15” wages. Even more challenging:

What if wind, solar and EV systems had to adhere to the “precautionary principle” – which says products must be banned until promoters can prove their technologies will never harm people or the environment?

The fair trade, et cetera rules are already enforced with an iron fist against non-renewable products by regulators, politicians, the news media and angry college students. It’s mostly the Progressive Left’s favored, supposedly renewable and eco-friendly energy “alternatives” and toys that get exempted.

ExxonMobil was fined $600,000 in 2009 for the deaths of 85 migratory birds that landed in uncovered oilfield waste pits. Compare that $7,000 per bird assessment to the zero to minuscule fines imposed once or twice on Big Wind companies for 85,000 dead eagles and hawks, and 8.5 million sliced and diced other birds and bats, over recent years. (These are artistic license numbers, but very close to the mark.)

The Keep It In The Ground campaigns against oil, gas and coal, the fossil fuel divestment movement on campuses, the anti-Israel Boycott Divestment and Sanctions (BDS) rabble, the incessant EarthJustice, Greenpeace and World Wildlife Fund lawsuits and campaigns against mining ignore all this, and more.

Just beneath the surface of cell phone, EV, computer, wind, solar and other technologies are some shocking and inconvenient truths. These products are not made from pixie dust or raw materials beamed in from the Starship Enterprise. All require lithium, rare earth metals, iron, copper, silica, petroleum and many other materials that must be dug out of the Earth, using human labor or fossil fuels.

Petroleum alone is the foundation for some 6,000 products besides fuels: paints, plastics, pharmaceuticals, cosmetics and much more. Lithium is essential in computer and EV batteries, neodymium in NdFeB wind turbine generator magnets, cadmium in PV solar panels, petroleum-based resins in turbine blades.

The vast majority of these minerals and metals could probably be found in economically recoverable or even world-class deposits in the United States. However, known deposits have been taxed, regulated and litigated into oblivion, while excellent prospects are mostly in western and Alaskan lands made inaccessible by Congress, courts, activists and Antiquities Act decrees. We’re not even allowed to look.

That has forced mining companies to go overseas. With few exceptions, American, Canadian, European and Australian companies pay good wages, abide by health and environmental rules, and invest heavily in local schools, libraries, hospitals, and water, sewage and electrical systems. But they are still pilloried, harassed and sued on a regular basis by radical groups in Peru, Guatemala and elsewhere.

The late Roy Innis, chairman of the Congress of Racial Equality, nailed it perfectly when he blasted the WWF for its callous campaign against a proposed mine in Madagascar.

“These enemies of the poor say they are ‘stakeholders,’ who want to ‘preserve’ indigenous people and villages,” Mr. Innis observed. “They never consider what the real stakeholders want – the people who actually live in these impoverished communities and must live with the consequences of harmful campaigns that are being waged all over the world,” blocking their opportunities, hopes and dreams.

These well-financed, self-righteous anti-mining assaults too often leave villagers jobless and the world dependent on shoddy state-run operations like the rare earth mines and processing facilities in Baotou, Inner Mongolia, and locally operated, often illegal “artisanal” mines in Africa and Asia. The environmental degradation and human health effects associated with these operations are horrendous.

Areas north of Baotou hold 70% of global proven reserves of rare earth minerals (REMs). The region was once productive farmland. But as Australia news, Business Insider, ABC News, Britain’s Guardian, BBC and Daily Mail, and others have documented, it is now a vast wasteland, where nothing grows.

Ores are extracted by pumping acid into the ground, then processed using more acids and chemicals. One ton of REMs releases up to 420,000 cubic feet of gases, 2,600 cubic feet of wastewater and 1 ton of other wastes – all of them acidic, toxic and radioactive. The resulting black sludge – laden with acids, heavy metals, carcinogens and other materials – is pipelined to what has become a foul, stinking, lifeless, six-mile-diameter “lake.” Its toxic contents are seeping into groundwater and creeping toward the Yellow (Huang He) River, an important source of drinking and irrigation water for much of northern China.

Miners and other workers labor up to 16 hours a day for a few yuan or dollars, under health, safety and environmental conditions that would likely have been intolerable in the US, UK and Europe a century ago. Dirty processing plants have few or no maintenance crews, little or no regular cleaning or repairs. Workers and local residents suffer from lung, heart and intestinal diseases, osteoporosis and cancer, at rates much higher than pre-mining days and well above those in other parts of the Middle Kingdom.

Meanwhile, Africa’s Congo region produces 60% of the world’s cobalt-lithium ore. Over 70,000 tons a year pass through the Congo DongFang International Mining Company to manufacturers in China. Entire families – including children as young as five – toil from dawn to dusk, for a dollar or two a day, so that cell phone, computer, EV and other buyers can enjoy cheap high-tech gadgets.

Generally without permits, health and safety standards or environmental rules, the parents and kids use picks, shovels, pails and bags to excavate deep holes and vast pits, in search of valuable ores. Cave-ins and mud slides are an ever-present risk. Depending on the weather, they work in dust or muck, getting dangerous levels of cobalt, lead, uranium and other heavy metals in their tissues, blood and organs.

Gloves, face masks, protective clothing and showers to wash the toxic dirt off bodies at the end of the day are also nonexistent. Broken bones, suffocation, blood and respiratory diseases, birth defects, cancer and paralysis are commonplace, the Guardian, Washington Post, NPR and human rights groups report.

Maybe those evils are better than prostitution for mothers and daughters, drug dealing and criminal gangs for fathers and sons, or starvation and death for entire families. But it certainly smells like exploitation.

Where are the Ben & Jerry’s and Fair Trade demands for justice? The Berkeley and Brown student protests, sit-ins and boycotts against Nokia, Samsung, Apple, Lenovo, Tesla, Vestas and Trina Solar? The demands that college endowment and teacher pension funds divest from these companies? The outraged US and EU student marchers in Baotou and Beijing, to support workers, Joshua Wong and Liu Xiaobo?

Where are the calls to replace state-run and artisanal mining operations with socially and environmentally responsible Western mining companies? Where is the WWF compensation to poor villagers for the wages, electricity, clean water and improved living standards they could have had?

Environmentalist policies don’t merely represent double standards. No matter how Greenpeace or the Sierra Club might disguise or sugarcoat them, radical green policies and campaigns are unjust, unethical, inhuman, imperialistic and racist.

It’s time to apply fair trade, living wage and environmental justice principles to the anti-mining, anti-people campaigners. Their real goal is keeping the Third World impoverished, and that is intolerable.

Bangladesh has drunk the Kool-aid

Bangladesh is set to impose its own carbon tax on fuel next month – despite the hugely climate-vulnerable country producing relatively tiny per capita emissions.

The tax is expected to be put in place on June 1 as part of the country's annual budget and will be part of a larger bundle of "green" measures, Nojibur Rahman, chair of the National Board of Revenue, told the Thomson Reuters Foundation in a telephone interview.

Many businesses and environmental groups have welcomed the plan, saying that Bangladesh – one of the countries considered most threatened by climate change impacts – needs to make a strong statement as governments like that in the United States pull back from action on climate change.

The new tax may not make any significant contribution to achieving the Paris Agreement's goal of keeping average global temperature increases below 2 degrees Celsius above pre-industrial levels, they said.

But "when a country pollutes, the other countries are also affected. So, we need to reduce carbon emission as much as possible and imposing a tax is only way to do it," said Abdul Matlub Ahmad, outgoing president of the Federation of Bangladesh Chambers of Commerce and Industry.

He said the tax would not only raise the price of using fossil fuels but the added income could help push more use of renewable energy.

"If the government wants to cut the import duty on environment-friendly renewable energy products, it needs to charge taxes on polluters," he said in a telephone interview.

Bangladesh produces about 0.44 tonnes of carbon dioxide per person, much lower than the United States' 16.4 tonnes, Australia's 16.3 tonnes and Qatar's whopping 40.5 tonnes, according to World Bank figures.

Carbon taxes – which raise the cost of using fossil fuels by creating a charge for the climate damage they do – are one of the simplest, most market-friendly ways of driving climate action, experts say.

But they have proved politically tricky to put in place, and not just in poorer parts of the world where incomes are low and making fuel more expensive can be politically risky.

But low-lying Bangladesh, which faces huge risks from sea level rise, worsening storms, floods, droughts and other climate change impacts, has made a name for itself as an international leader in climate action, particularly in terms of innovative adaptation to climate change.

"Although our contribution to climate change is very nominal, we are one of the worst victims of climate change. Aware of the problem, we have the most successful and best climate change programmes the world has so far witnessed in any country," Finance Minister A.M.A. Muhith, said earlier this month at a Dhaka summit on climate change and disaster risk reduction.

While it seeks international finance to help with programmes to address climate change, Bangladesh also has paid for projects out of its own nationally funded climate change fund.

M.A. Matin, general secretary of the Bangladesh Poribesh Andolon (Bangladesh Environment Movement), said in a telephone interview that any carbon tax would need to be accompanied a "long-term carbon reduction plan" from the government.

In the short term, higher taxes on industry can drive up production costs, with those costs passed on to consumers. That might mean "it's not a right method for reducing emissions," he said.

John Coleman’s Crusade: Battling 97% on ‘Global Warming Silliness’

They throw a lot at Colemen below but also give him reasonable opportunity to reply

John Coleman says Al Gore started it — the “global warming silliness.” But now the retired KUSI weatherman is “horrified” to see San Diego Mayor Kevin Faulconer channeling the ex-veep with a Climate Action Plan. It “just turns my stomach.”

“I think he saw money and power, and I don’t know what else he thought of it,” Coleman says of the Republican mayor. “I can’t believe he really [felt he] was going to save the city from some terrible fate.”

Coleman, 82, laughs during a lively phone chat from his home near Las Vegas.

“San Diego’s not going to go underwater. Period,” he says. “Not in my lifetime or yours or our kids’ lifetime. When the Earth ends in 4 1/2 billion years, it probably still won’t have flooded.”

He also mocks “the damn tsunami warning route signs that they put up all over the city,” which he calls “about as silly as anything I’ve ever saw in my life. The chance of a significant tsunami hitting Southern California is about as great as a flying saucer landing tonight at Lindbergh Field. It’s just sheer nonsense.”

Coleman also knows how many people regard his decade-old public arguments. As sheer nonsense.

He’s unapologetic. “I’m just a dumb old skeptic — a denier as they call me — who ought to be jailed or put to death,” he says. “I understand how they feel. But you know something? I know I’m right. So I don’t care.”

That’s clear from his Twitter feed, “climate frenzy” blog and occasional political activism — he made hundreds of phone calls (reading a script) urging votes for Donald Trump during the primaries.

“I went to the opening of the Trump campaign headquarters in Nevada, and that sort of thing,” he says of the man who labels climate change a hoax. “I went to one of his rallies.”
Coleman aims to expose what he calls “Algorian” scientists fudging data and taking billions in government research grants for the sake of career advancement and economic comfort.

At KUSI, with financial backing from the Republican McKinnon family, Coleman hosted two hour-long documentaries critical of the notion of manmade climate change. He did many news pieces.

Coleman calls global warming a scientific issue, not a political one. “But since it had become a political issue, [Michael D. McKinnon] strongly supported my skeptical position on global warming,” he says. “If it hadn’t been for that, I probably would have retired much sooner. [KUSI] gave me a great platform from which to work.”

How did Coleman go from the clowning meteorologist of ABC’s “Eyewitness News” in Chicago to the Kay-YOOOOOUUUU-Es-Eye crusader against “the greatest scam in history”?

Several stories are told.

Charles Homan of Columbia Journalism Review said Coleman “snapped” while watching an Eagles-Cowboys football game one Sunday night when TV studio lights were cut as a “green” gesture.

“I couldn’t take it anymore,” Coleman told Homan in that 2010 piece. “I did a Howard Beale.”

Coleman also points to Gore’s Oscar-winning “An Inconvenient Truth” of 2006. “I think the Al Gore movie probably stimulated me more than anything,” he now says. “I’m happy to see that his new movie seems to be less than spectacular success.”

But the seeds were planted decades before Coleman’s 2007 manifestos.

Coleman credits Joseph D’Aleo, his meteorological director at The Weather Channel and forecast assistant at “Good Morning America.”

“We started together in 1977, I guess,” he says. “He’s the one who has taught me about climate skepticism, about Algorian skepticism, and I learned it through him. And then I learned it through Willie Soon. It goes way, way back before 2007.”

In January 2010, responding to an “Other Side” broadcast on KUSI but not using Coleman’s name, research professor emeritus Richard Somerville of the Scripps Institution of Oceanography issued a 550-word, six-point “Response to Climate Change Denialism.”

In July 2014, John P. Reisman offered a line-by-line rebuttal to Coleman’s arguments in “The Amazing Story Behind the Global Warming Scam.”

On July 1, 2017, fact-checking site Snopes.com labeled as “False” the assertion — circulating after Trump pulled out of the Paris climate accords — that “Weather Channel co-founder John Coleman provided evidence that convincingly refutes the concept of anthropogenic global warming.”

Coleman went on several national shows after his April 2014 exit from KUSI, including Fox News (with Megyn Kelly) and CNN (with Brian Stelter), to make his case.

But Coleman confessed to Times of San Diego that his TV turns are drying up.

He says a CBS production company contacted him about an interview for an hourlong TV show. “And we talked and talked and everything was scheduled,” Coleman says. “And then two days before the shoot was to occur, they called and said, ‘Sorry, we have to cancel that. Thank you very much anyway.’

“Because?” Coleman asked. “Well, you know,” came the reply. Said Coleman: “That happens all the time.”

Coleman doubles down: “I understand that there are plenty of people who rip me to shreds, and you can find strong and powerful put-downs on every topic I’m talking about. … But the truth is that I know all about all that stuff, and I don’t give a rat’s ass, because I know I’m right.”

In the phone chat, Coleman was asked about “97 percent of climate scientists” citing manmade change.

Coleman shot back: “Do you believe that? That’s sheer nonsense.”  He called it a “totally contrived figure” that gained ultimate currency when it was “uttered by President Obama. … But it’s totally fabricated. The so-called research that came up with that 97 percent was done by people who were looking to produce that figure and had to manipulate everything they got.”

He directed me to wattsupwiththat.com to view “eight or nine well-done articles that debunk the 97 percent.”

So where did the 97 percent come from?

Coleman’s says it’s just the share of scientists who agree the earth is warming, which even Coleman concedes.

“You’ve had Ice Ages and glacial periods, warm spells, one after another, cycling back and forth,” he says. “And certainly man didn’t cause any of them. They’re all natural events.”

He says the American Meteorological Society, in its most recent survey, “came up with about 47 percent skeptical, so 53 percent support (manmade climate change). And that’s after the society did everything they can to promote it. The society has been totally politicized. And still they can’t get all their members aboard.”

But contacted this week, AMS spokesman Tom Champoux provided links to several reports and blogs, including its 2016 survey of members which found “only 5 percent [of survey respondents] said that climate change was ‘largely or entirely’ due to natural events.”

“Mr. Coleman’s assertion that the 97 percent figure is ‘totally contrived’ and was ‘uttered by President Obama’ is in no way accurate,” said Champoux, who pointed to a British science nonprofit’s conclusion that “amongst 1,381 papers self-rated by their authors as stating a position on human-caused global warming, 97.2 percent endorsed the consensus.”

The AMS survey did find a 53 percent figure, however: “A total of 4,092 AMS members participated, with participants coming from the United States and internationally. The participation rate in the survey was 53.3 percent.”

Another evergreen Coleman critique is that billions of dollars of research grants go only to scientists who support the global warming theory: “You MUST take the Algorian side or you’re dead meat.”

He cites “the great Judith Curry,” an accomplished climate scientist who left her job at Georgia Tech “because she couldn’t handle it anymore” — reaction to her skeptical positions. He noted “my great friend Willie Soon at the Smithsonian Institute, whose life has been turned to hell because of his position.”

He says the power of money — $20 billion a year — buys opinion. “But even THAT has not produced a 97 percent consensus, so that consensus figure is a dead-in-the-ringer lie.”

But what about that fact Republicans control the pursestrings?

Coleman is ready. “Have you heard the chant ‘Drain the swamp’? I don’t think the swamp is only Democrats and bureaucrats. … Lord help me, the Republican Congress is very unlikely to cut off funding projects of the Scripps Oceanographic Institute or Woods Hole or any of the others. The Republican Party, they’re a slimy fish swimming through the swamp.”

Coleman agrees that Trump would like to shut the spigot. But not because he has a strong position on climate science. It’s just for budget savings.

“But I’m also confident that his family … they’re going to have dinner with him at night: ‘Hey, Dad, we got to keep this money flowing.’ So I don’t know how successful it will be. But I know the two most powerful forces on earth are sex and money. And by God it’s really hard to shut off the money. And it’s really hard to not go for the sex.”

What about Sacramento’s cap-and-trade measure — passed with GOP help?

“Just pure and total embarrassing nonsense,” Coleman says, “And another darn good reason not to live in California. If I have to get a passport to come see my son in Palm Springs in the future, so be it. That state has gotten so silly. Oh my God, I’m so glad I don’t live there.”

He calls efforts to reduce carbon dioxide emissions “an insult to the average American family,” whose energy costs already rise $2,500 a year “because of the threat of so-called global warming. And that cap-and-trade will take it up to probably $4,800 a year.”

“That takes phones away from the kids, or they don’t get new tablets so they can do their homework right. Or the college fund is down. Or clothes or vacations. It hurts that family very deeply. And these politicians who live on the top edge don’t have any understanding or feeling for the average people. And it drives … me … nuts,” he says, pausing between words for emphasis.

Does Coleman regard La Jolla’s prestigious Scripps Institution of Oceanography — a groundbreaker in climate studies — as doing fake science?

“I think that they are dead wrong,” Coleman says. “I think the Keeling Curve is excellent science — the measurement of carbon [dioxide] in the atmosphere through the years and the development of that good steady flow of data. That’s a very good scientific piece of work.”

But the rest of Scripps’ studies?

“Just pathetic,” he says. “And it drives me nuts. A fine institution just went … where the money is. Without that money, hundreds of people would have to be let go.”

He asks: “Have you looked at my video where I tell about that dispute between [Scripps and UCSD legend] Roger Revelle and [his Harvard student] Al Gore? I gather it didn’t impress you. I’m convinced that it’s correct [that climate scientist Revelle didn’t urge action on human-caused global warming]. By the way, that has over a million views on YouTube.”

(Revelle’s daughter Carolyn said Coleman and others took his remarks out of context.)

A spokeswoman for Scripps — once ranked No. 1 in the nation for earth and environmental sciences by the journal Nature — said Somerville’s post still holds up seven years later, and she also noted that “while Mr. Coleman was at KUSI he was invited here many times to see the research in action and talk to scientists. He never came.”

Mayor Faulconer’s office did not respond to a request for comment.

But Masada Disenhouse did. The founder of climate action group SanDiego350 — who helped organize the downtown Climate March in April — defended the mayor and countered Coleman on other issues.

“I think that the mayor of San Diego took climate change seriously and has moved to address it is because it’s been clear from polling, elections, growing climate marches and activism, and other indicators, that the people of San Diego increasingly support moving to clean energy and addressing the climate crisis,” she said Wednesday via email. “And when the people lead, the elected officials who represent them follow.”

On Coleman’s rejection of a waterlogged San Diego: “While Mr. Coleman may be in denial about it, coastal flooding due to sea level rise is already a problem in our coastal areas like Imperial Beach, Mission Beach and Carlsbad, with some areas expected to flood regularly at high tide in the next few decades.”

Disenhouse says Miami and New Orleans are a preview — “facing flooding from high tides even on sunny days on a regular basis right now.”

In 2015, she noted, SanDiego350 drew a chalk line in Mission Beach’s retail area to show where high tide would reach if trends continue until 2050.

Disenhouse defended efforts to wean the economy from fossil fuels.

“California’s economy has been growing as it has reduced its energy use per person and begun to bring down greenhouse gas emissions,” she says. “In fact, the renewable energy sector has been hugely successful in California, one of the fastest growing job sectors.”

But here Coleman concurs. “I love solar power,” he says. “But what does that have to do with climate change? Not a dibble-dee-do-dot.”

He says people assume that that if he’s a climate skeptic or opposed to cap-and-trade that he’s against solar or wind power or environmentalism, “or I want to fill the oceans with plastic or something.”

Coleman insists: “I am an environmentalist through and through. So don’t give me any of that. My son has solar on his house. And pays $16 a month for power in Palm Springs, and I’m excited about the future of graphene.”

He says a day will come when homes are coated with graphene paint and homeowners “disconnect the power line.” Same with the car.

“The age of fossil fuels and the electric grid will come to an end,” Coleman says. “Not in my lifetime, but possibly in yours. Time will tell and it’s all wonderful. Our life is good today not because a bunch of politicians have made laws and regulations and try to tell us how to live. Our lives are good today because of science.”
