That would be from the Heartland and Cato institutes with their renowned links to the oil billionaire Koch brothers!

Why would anyone on the left fund rational or scientific inquiry on global warming alarmism?

Those institutes are all about protecting the fossil fuel industries and nothing to do with either rational or scientific enquiry.

"Ocean warming 'underestimated,' study finds

Miami (AFP) - The amount of sea level rise that comes from the oceans warming and expanding has been underestimated, and is likely about twice as much as previously calculated, German researchers said Monday.

The findings in the Proceedings of the National Academy of Sciences, a peer-reviewed US journal, suggest that increasingly severe storm surges could be anticipated as a result.

Sea level can mount due to two factors -- melting ice and the thermal expansion of water as it warms.

Until now, researchers have believed the oceans rose between 0.7 to one millimeter per year due to thermal expansion.

But a fresh look at the latest satellite data from 2002 to 2014 shows the seas are expanding about 1.4 millimeters a year, said the study.

"To date, we have underestimated how much the heat-related expansion of the water mass in the oceans contributes to a global rise in sea level," said co-author Jurgen Kusche, a professor at the University of Bonn.

The overall sea level rise rate is about 2.74 millimeters per year, combining both thermal expansion and melting ice.

Sea level rise was also found to vary substantially from place to place, with the rate around the Philippines "five times the global rate."

Meanwhile, sea level on the US West Coast is largely stable because there is hardly any ocean warming in that area, said the findings.

In other words, all the predictions by the global warming alarmists come from computer simulations. The scientists who make the predictions routinely announce there were wrong because the simulation model was wrong.

"Scientists are floored by what’s happening in the Arctic right now

Temperature anomalies for January, 2016. NASA Goddard Institute for Space Studies

New data from NASA and the National Oceanic and Atmospheric Administration suggest that January of 2016 was, for the globe, a truly extraordinary month. Coming off the hottest year ever recorded (2015), January saw the greatest departure from average of any month on record, according to data provided by NASA.

But as you can see in the NASA figure above, the record breaking heat wasn’t uniformly distributed — it was particularly pronounced at the top of the world, showing temperature anomalies above 4 degrees Celsius (7.2 degrees Fahrenheit) higher than the 1951 to 1980 average in this region.

Indeed, NASA provides a “zonal mean” version of the temperature map above, which shows how the temperature departures from average change based on one’s latitude location on the Earth. As you can see, things get especially warm, relative to what the Earth is used to, as you enter the very high latitudes:

Image

Global warming has long been known to be particularly intense in the Arctic — a phenomenon known as “Arctic amplification” — but even so, lately the phenomenon has been extremely pronounced.

This unusual Arctic heat has been accompanied by a new record low level for Arctic sea ice extent during the normally ice-packed month of January, according to the National Snow and Ice Data Center — over 400,000 square miles below average for the month. And of course, that is closely tied to warm Arctic air temperatures.

“We’ve looked at the average January temperatures, and we look at what we call the 925 millibar level, about 3,000 feet up in the atmosphere,” says Mark Serreze, the center’s director. “And it was, I would say, absurdly warm across the entire Arctic Ocean.” The center reports temperature anomalies at this altitude of “more than 6 degrees Celsius (13 degrees Fahrenheit) above average” for the month.

The low sea ice situation has now continued into February. Current ice extent is well below levels at the same point in 2012, which went on to set the current record for the lowest sea ice minimum extent:

Image

“We’re way down, we’re at a record low for this time of year right now,” says Serreze. When it comes to the rest of 2016 and the coming summer and fall season when ice melts across the Arctic and reaches its lowest extent, he says, “we are starting out in a deep hole.”

So what’s causing it all? It’s a complicated picture, say scientists, but it’s likely much of it has to do with the very strong El Niño event that has carried over from 2015. But that’s not necessarily the only factor.

“We’ve got this huge El Niño out there, we have the warm blob in the northeast Pacific, the cool blob in the Atlantic, and this ridiculously warm Arctic,” says Jennifer Francis, a climate researcher at Rutgers University who focuses on the Arctic and has argued that Arctic changes are changing mid-latitude weather by causing wobbles in the jet stream. “All these things happening at the same time that have never happened before.”

Serreze agrees that the El Niño has something to do with what’s happening in the Arctic. “I think this is more than coincidence. That we have this very strong El Niño at the same time when we have this absurd Arctic warmth. But exactly what the details are on that, I don’t think we can say right now,” he says.

In Alaska, matters have been quite warm but not record-breaking this winter, says Rick Thoman, climate science and services manager for the National Weather Service in the state.

“It’s been another warm winter in Alaska,” Thoman says. “No other way to put it. This is the third in a row that’s been significantly warmer than normal.” Alaska’s winter so far (taking into account the months of November, December and January) has been the third warmest on record since 1925, he says.

Still, it all fits a by-now familiar picture of an Arctic warming up considerably faster than the mid-latitudes, with consequences that could extend far outside of the polar region, says Rafe Pomerance, a former deputy assistant secretary of state who sits on the National Academy of Sciences’ Polar Research Board.

Impacts of Arctic warming are usually considered in isolation, and that’s a mistake, he says. “It’s unraveling, every piece of it is unraveling, they’re all in lockstep together,” Pomerance says. “What tends to happen is, everybody nationally reports on the latest piece of news, which is about one system. You hear about the sea ice absent the temperature trend. So you really have to think of it as a whole.”

Indeed, impacts of Arctic warming include the melting of major Arctic glaciers and Greenland (containing the potential for up to 7 meters of sea level rise if it were to melt entirely), the thawing of carbon rich permafrost (which could add to the burden of atmospheric greenhouse gas emissions) and signs of worsening wildfires across the boreal forests of Alaska, to name a few.

If the Arctic is this warm in January and February, then when real warmth comes later this year, these will all be areas to watch.

“I think this winter is going to get studied like crazy, for quite a while,” says Francis. “It’s a very interesting time.” "

Nature just published an article, 'Making sense of the early-2000s warming slowdown' by some top global warming scientists, including authors of the IPCC assessments. The summary: It has been claimed that the early-2000s global warming slowdown or hiatus, characterized by a reduced rate of global surface warming, has been overstated, lacks sound scientific basis, or is unsupported by observations. The evidence presented here contradicts these claims.

For those of you thrown off by negatives, what it says is the early 2000s global warming slowdown is real. For those who don't know the former beliefs of the authors and the IPCC, this article is a 180 degree switch.

The article is behind a paywall. Visit your favorite souce of spin for their opinions on an article they probably didn't read. http://www.nature.com/nclimate/journal/ ... e2938.html

That article chooses a data set that stops just before 2015, the warmest year on record, so it's conclusions are already obsolete.

"Global Warming Could Be Leading to Better French Wine

Image

Among all the global warming effects scientists have been warning us about for decades, one of them could have been increasing the quality of French wine.

Higher temperatures in France have condensed the usual growth cycles for wine grapes, and have resulted in earlier harvests, a condition that is usually associated with higher-quality wine, according to a study released on Monday in the Nature Climate Change journal.

“There is a very clear signal that the earlier the harvest, the much more likely that you’re going to have high-quality wines,” Benjamin Cook, one of the study’s co-authors and a climate scientist with NASA’s Goddard Institute for Space Studies, told NPR. ..."

Basically, the optimum area for growing winemaking grapes is moving north, some areas of Northern Europe will improve and some to the South will become too hot as apparently the temperature range for good wine grapes is 12-22C. Some parts of California are also starting to get too hot for good grapes.

There was another report suggesting that France could become too hot to continue making quality Champagne and that it could swing north to England for them to overtake France in producing sparkling wine - already some of the English sparkling wine wins awards against many of the French Champagnes.

States' Rights!

Eric Schneiderman and Sheldon Whitehouse, call your office. The New York Attorney General and Rhode Island Senator who helped to launch the prosecution of dissent on climate change may not like where their project is headed. Thirteen state Attorneys General have sent a letter pointing out that if minimizing the risks of climate change can be prosecuted as “fraud,” then so can statements overstating the dangers of climate change.

"The ground in Siberia is turning into a trampoline, and we should all be worried

The ground in Siberia has been behaving strangely for a while now.

Remember those insanely giant craters that opened up out of nowhere? And how recently one of them exploded so violently that you could hear it from 60 miles away?

You can add this to the list of strange things that the ground really shouldn't do.

Image

Why is the ground bouncing like some sort of unholy trampoline?

According to a story at the Siberian Times scientists aren't totally sure yet.

But it's probably for similar reasons to those terrifying, hell-mouth craters that keep opening up. The unseasonably warm weather in the Arctic regions — and, let's be honest, everywhere — is causing permafrost, the ground that should literally be permanently frozen, to thaw.

When permafrost thaws into soft soil, the liquid methane trapped underneath is released as a gas. This seems to be the case here: The research team who discovered the 15 or so patches of wobbly ground told the Siberian Times that methane and carbon dioxide emanated from the patch when they pierced it.

Methane and carbon dioxide are potent greenhouse gases, which trap heat in the atmosphere. One study found that if permafrost all over the world releases the gases bottled up underground, then we could double the amount of carbon emissions in the atmosphere. ..."
