Guardian: 205 Feet Of Sea Level Rise By 2095!

In case you forgot for a minute that the left lives in a mindless, fact-free fantasy world, the Guardian is predicting Florida will soon be underwater. Rising seas: ‘Florida is about to be wiped off the map’

Actual data from Florida shows no change in the slow rate of sea level rise over the past century.

ONLY 0.8% Of Tidal Gauges Show Sea Level Rise Near IPCC’s Alarmist Predictions!

Accurately measuring the sea level with a satellite is highly complex and fraught with uncertainty. Even the slightest equipment miscalibrations can produce inaccurate results.

For sea level rise, the figures that are often cited come from namely two sources: satellite measurement, which goes back 25 years and therefore doesn’t properly account for multidecadal variations, and tidal gauges placed along the coastlines where people actually live.

Satellite data may be overstating sea level rise

The assumed current global sea level rise from the satellite data TOPEX/Poseidon spacecraft and its successors, which began collecting data in late 1992, was reported by NASA’s Jet Propulsion Laboratory (JPL) to be 2.8 inches(seven centimeters).

Some experts recently warned, however — after having made adjustments to the satellite measurements — that sea level rise has accelerated and thus could increase some 75 centimeters over the century, which would be in line with projections made by the Intergovernmental Panel on Climate Change (IPCC) in 2013.

Other sources say that sea level rise could be as much as 3.4 mm per year, and thus accelerating (e.g., see chart above).

Indeed, if these high-end projections were accurate, then coastal areas would be facing serious challenges. But those alarmist claims have been met critically, and at times even with derision.

There remains lots of uncertainty, and so the question today is: How much are coastal areas (where it really matters) at risk really?

Tide gauges: “most extensive, accurate and significant” datasets

One way to check what’s really going on is to examine the tide gauges along the coasts worldwide. Since the early 1800s, NOAA and its predecessor organizations have been measuring tide levels.

According to the NOAA, “This database has become one of the most extensive, accurate and significant geophysical data sets in existence.”

To do this the NOAA keeps a coastal station tide list for tracking global linear relative sea level (RSL). Manually I counted 358 stations.

A number of them stopped measurement some years ago, while others were put in operation in the 20th century. The list appears not to include the US tide gauges.

The data and charts can be looked at country-by-country here.

Less than 1% on track to meet IPCC’s 75 cm sea level rise by 2100

Examining the data to get a general idea of how the sea level is behaving at these tide stations. A number of points were observed:

1) Only three stations show an RSL rise of 7.5 mm/year or more, meaning that only three stations (0.8%) are on track to reach the IPCC’s alarmist 75 cm sea level rise projection by 2100. And if we use the more conservative 60 cm rise, only five stations (1.4%) are on track!

Only 14% show a rise equal to or greater than satellite global rate

2) Only 51 tide gauges (14%) are measuring 3.2 mm/year or more, which is approximately equivalent to about what the satellites are said to be measured globally. That figure would need to be near 50% if the satellites were true.

3) Fifty-four coastal tide gauges (15%) show that relative sea level has in fact been falling.

4) The mean relative sea level rise as to the tide gauges is about one third less than what is measured by the satellites, i.e. approx. 2.3 mm per year, or less than 10 inches per century.

This is only a rough overview. Naturally, a more detailed look recent tide gauge trends of the last two or three decades would tell us more about the accelerating sea level rise. Or maybe not: rate changes over such short time periods have more to do with natural variations.

So in general? If you’re living and working at the institutes who operate the satellites, then you might be showing concern about the figures you’re getting (it’ll help with funding, in any case).

But if you’re the average person living near the coast, then in most places there’s not much to be alarmed about. There’s a good chance the satellites are overstating sea level rise just a bit and so you can better rely on what your local tide gauge has been showing.

The coldest place on Earth is even chillier than scientists thought: Temperatures plummet to -148F in 'supercold' areas of Antarctica's ice sheet

So a few degrees of atmospheric warming is supposed to melt it??</>

The coldest place on Earth is even colder than thought, a new study has found.

Researchers discovered tiny valleys near the top of Antarctica's ice sheet reach temperatures of nearly minus 100 degrees Celsius (minus 148 degrees Fahrenheit) in the winter.

The results could change scientists' understanding of just how low temperatures can get at Earth's surface, according to the researchers.

The coldest spot on Earth was found on the East Antarctic Plateau, a high snowy plateau in central Antarctica that encompasses the South Pole.

The record breaking temperatures occur occurred in small hollows 2 to 3 meters (6 to 9 feet) deep in the surface of the ice, on the southern side of high ridges on the plateau.

The record of minus 98 degrees Celsius is about as cold as it is possible to get at Earth's surface, according to the researchers.

Scientists used satellite data between 2004 and 2016 to come up with the minus 144 degrees Fahrenheit figure, as the eastern plateau of Antartica is a barren, snowy region where surface-based weather instruments aren't available .

Small low-lying dips in the Antarctic ice sheet had the most frigid temperatures, they found.

Because cold air is dense, it funnels into the dips where it may stay trapped for several days when skies are clear and winds are light.

This is similar to how cold air drains into valley locations at night elsewhere in the world.

Scientists first announced in 2013 they had found the lowest temperatures on Earth's surface in the area.

Sensors on several Earth-observing satellites measured temperatures of minus 93 degrees Celsius (minus 135 degrees Fahrenheit) in several spots on the East Antarctic Plateau, a high snowy plateau in central Antarctica that encompasses the South Pole.

But the researchers revised that initial study with new data and found the temperatures actually reach minus 98 degrees Celsius (minus 144 degrees Fahrenheit) during the southern polar night, mostly during July and August.

When the researchers first announced they had found the coldest temperatures on Earth five years ago, they determined that persistent clear skies and light winds are required for temperatures to dip this low.

The new study found not only are clear skies necessary, but the air must also be extremely dry, because water vapor traps some heat in the air.

The high elevation of the East Antarctic Plateau and its proximity to the South Pole give it the coldest climate of any region on Earth.

The lowest air temperature ever measured by a weather station, minus 89 degrees Celsius (minus 128 degrees Fahrenheit), was recorded there at Russia's Vostok Station in July 1983.

UK: Nuclear sector deal signals support for 'baby' atomic power plants

Small Modular Reactors are hoped to offer a cheaper alternative to conventional nuclear power stations such as Hinkley Point

A new generation of “mini” atomic power plants in the UK will get the strongest signal yet of government support on Thursday when the industrial strategy’s nuclear sector deal is unveiled.

Business and Energy Secretary Greg Clark is due to set out £200m of funding for the industry at the nuclear-licensed Trawsfynydd site in North Wales.

While the bulk of the money is a re-announcement of support pledged last year, industry insiders say the site chosen to launch the sector deal is important.

Trawsfynydd is seen as the most likely location for a small modular reactor (SMR) – a new design of a baby nuclear plant which produces far less power than a traditional atomic plant such as Hinkley Point.

Share bikes a failure in Australia

A Greenie dream dies.  Many people who hire them are too lazy to return them

Bike-sharing service oBike is staying in Sydney despite piles of the disused bicycles ending up dumped in streets and waterways across the city.

OBike is no longer in service in Melbourne after the city council started issuing fines for illegal dumping.

The company has also announced it would stop operating in its home base of Singapore.

An oBike spokesperson told the ABC it was 'not leaving Australia'. 'Our service is as usual. Meanwhile we are also working closely with local authorities in Melbourne for a detailed discussion on how we can better provide our service.'

The company's decision to withdraw from Melbourne comes after the  Environment Protection Authority announced steep new fines of $3,000 per dumped bike, payable by the business.

There are at least four bike-sharing companies in Melbourne and Sydney including oBike and ReddyGo which were launched last year after being popularly used overseas.

The heavily criticised share bike industry, which also operates in other major cities across the country, often leaves pedestrians frustrated as the bikes are left strewn across footpaths or thrown into trees.

Port Phillip Mayor Bernadene Voss told radio station 3AW she had been informed the bikes were on their way out of Melbourne.

'We've been told they are going,' she said. 'We do understand though that there is a new operator coming in.'

Melbourne Lord Mayor Sally Capp asked people to stop using the rental scheme after the company confirmed it was pulling out of Melbourne, following controversy and hefty fines over bikes dumped on streets, up trees and in waterways.

'oBikes have decided to withdraw from our market here in Melbourne and we are working very closely with them to remove oBikes from the city streets,' she told reporters.
