Climate change: Impacts 'accelerating' as leaders gather for UN talks

[Lord of Planar]

What facts would those be? Maybe like 15 of the 16 hottest years in civilized human history have been subsequent to 2000?

Maybe the hottest after using averages instead of peaks, and after "corrections" are done to the records. And we shouldn't forget the contamination of monitoring stations by the urban heat island effect.

I agree they are that. Just not the way you think they really represent.

 

[Lord of Planar]

The facts that only you know?

The ones scribbled on your wall?

It's not that I know any facts they don't know. It's that I see the known unknowns, and know that they play a larger part than accounted for by the scientists, who don';t even try to quantify them.

Now why don't they try to quantify them? Because they know if they do, the results of their papers would not fit the criteria they are getting the grant money for.

Publish or die...

This site explains the gathering of worldwide temperature information. You can probably write to the NOAA and NCEI, and tell them what they are doing wrong. :roll:

World Weather Records

World Weather Records (WWR) is an archived publication and digital data set. WWR is meteorological data from locations around the world. Through most of its history, WWR has been a publication, first published in 1927. Data includes monthly mean values of pressure, temperature, precipitation, and where available, station metadata notes documenting observation practices and station configurations. In recent years, data were supplied by National Meteorological Services of various countries, many of which became members of the World Meteorological Organization (WMO).

Yep.

So you should publish.

Because of all your hard work ‘seeing known unknowns’. [emoji849]

This is a direct Bridenstine quote: "Human beings are contributing to Global Warming in a major way."

Having been an outspoken denier at one time, I'd say he is either sincere in his conversion, or he's a very good liar.

It is also a huge shift from 2013 then Bridenstine on the floor of the House of Representatives said these words:

"Mr. Speaker, global temperatures stopped rising 10 years ago. Global temperature changes when they exist correlate with Sun output and ocean cycles. During the Medieval Warm Period, from 800 to 1300 AD, long before cars, power plants, or the Industrial Revolution, temperatures were warmer than today. During the Little Ice Age, from 1300 to 1900 AD, temperatures were cooler. Neither of these periods were caused by any human activity. Even climate change alarmists admit that the number of hurricanes hitting the U.S. and the number of tornado touchdowns have been on a slow decline for over a hundred years. But here's what we absolutely know: We know that Oklahoma will have tornadoes when the cold jet stream meets the warm Gulf air. And we also know that this president spends 30 times as much money on global warming research as he does on weather forecasting and warning."

While today Bridenstine instead state that NASA is the agency in the world that have the most credible to do the science to understand manmade global warming (in the video).

There NASA clearly acknowledge the urgent need for action on manmade global warming.

[Bergslagstroll]

Who cares what he believes in- he's just one of many government bureaucrats who want to hype climate change so his agency gets funded and his employees gets paid.

US have a president that have claimed that climate change is a Chinese hoax.

Donald J. Trump on Twitter: "The concept of global warming was created by and for the Chinese in order to make U.S. manufacturing non-competitive."

Trump also for example wants to spend billions on propping up unprofitable coal plants.

So why would Trump want to give more money to NASA if they acknowledge the urgent need for action on climate change?

Also Republicans controlled both the presidency and the two chambers of congress for two years. So NASA could instead get more money to disprove the urgent need for action on manmade global warming if any evidence against the urgent need had existed.

You seem to know more about the National Academy of Science than the National Academy of Science. :roll:

Reputation | National-Academies.org | Where the Nation Turns for Independent, Expert Advice

Over many decades, the National Academies of Sciences, Engineering, and Medicine have earned a solid reputation as the nation's premier source of independent, expert advice on scientific, engineering, and medical issues.
...
"In a trio of reports released in May, the prestigious and nonpartisan National Academy [of Sciences] concluded that 'a strong, credible body of scientific evidence shows that climate change is occurring, is caused largely by human activities and poses significant risks for a broad range of human and natural systems.'

Jim Bridenstine, Trump's appointed head of NASA also states that he see to that NASA climate change is free and void from partisan and political rhetoric by following the guidance of National Academy of Science.

Bridenstine may be barking up the wrong tree there. It doesn't make any difference what scientific organization espouses AGW theories. They will be attacked by deniers, pseudo-science, and oil-industry propaganda.

Have I ever said warming hasn't changed?

Why do you present material that doesn't support your argument?

Yes Sweden is so powerful that the country controlled NASA and all the other federal agencies climate research under Bush and now under Trump. That it's the Swedish prime minister that have forced American federal agencies under Donald Trump to publish this report.

Yes powerful economical and political interests continue with their disinformation campaigns.

"Robert Brulle, professor of sociology at Drexel University and an expert on climate science denial, told DeSmog it looked like a panicked response to the significant media coverage on the climate crisis after influential protests by Extinction Rebellion and Greta Thunberg.

“The talking points are stale and patently scientific nonsense. That isn’t critical. The point would be to keep the ‘contested’ nature of climate change alive,” he said.

Geoffrey Supran, a postdoctoral fellow at Harvard University, said he thought the move was an attempt to distract efforts to increase action at the UN Climate Action Summit at the end of the month."

While at the same time the evidence is so overwhelming and the warnings from the world's leading scientists so clear. So that the deniers are becoming a smaller and smaller minority.

Yes that denier propaganda have not only been about denying the overwhelming evidence of manmade global warming, but also scare people that any action on climate change will lead to doom and gloom. While the reality is that even local republican politicians are seeing the great benefits of renewable energy.

Why Republican Leaders Love Renewable Energy

You have also positive examples like Germany there coal workers have gotten new jobs.

How Germany closed its coal industry without sacking a single miner

Spain will also create new opportunities for laid off workers.

Another reason for people denying the overwhelming evidence is partisanship that lead to that if fossil fuel companies but politicians they also get the politicians supporters into the bargain.

Manmade global warming can lead to that clouds’ cooling effect could vanish.

"Low-lying cloud banks off the coast of California, Peru and Namibia are some of the planet’s most effective cooling systems, because they reflect sunlight back into space. But new climate simulations show that increasing carbon dioxide concentrations in the atmosphere could break up these cloud layers and exacerbate future warming.

The findings1, published on 25 February in Nature Geoscience, reveal a previously unknown interaction between clouds and greenhouse gases: about three times the current level of atmospheric carbon dioxide can abruptly disperse clouds. Under a business as usual emissions scenario, this could occur in about a century. A world with fewer clouds, projections indicate, could witness up to 8ºC of warming in addition to that caused by greenhouse gases. Earth’s climate would be similar to conditions 50 million years ago, when crocodiles swam in an ice-free Arctic and palm trees grew as far north as Alaska."

There are a bunch of nuts, fruitcakes and self centered libertarians who also are in that third.

Worrying signs from all across the world.

"Scientists in Siberia have discovered an area of sea that is "boiling" with methane, with bubbles that can be scooped from the water with buckets. Researchers on an expedition to the East Siberian Sea said the "methane fountain" was unlike anything they had seen before, with concentrations of the gas in the region to be six to seven times higher than the global average.

The team, led by Igor Semiletov, from Tomsk Polytechnic University in Russia, traveled to an area of the Eastern Arctic previously known to produce methane fountains. They were studying the environmental consequences of permafrost thawing beneath the ocean."

Permafrost melting, and the subsequent release of methane is scary. It is one of many POSITIVE feedbacks of a warming world, that will accelerate warming to even greater degrees. These feedbacks are factored into the IPCC reports, and the scientific studies of the major scientific organizations - National Academy of Science, the Royal Academy, NASA, and the American Meteorological Society.

Please explain why such a small increase in the earths greenhoese gas content is a proble.

Show us the math that such an increase causes in warming. RE and GWP doesn't count, as they are irrelevant to real science.

Melting permafrost is a Positive feedback, but not the predominant one. According to the NAS --->

http://dels.nas.edu/resources/static-assets/exec-office-other/climate-change-full.pdf

The most important amplifying feedback is caused by water vapour, which is a potent greenhouse gas in the
atmosphere as warmer air can hold more moisture. Also, as Arctic sea ice and glaciers melt, more sunlight
is absorbed into the darker underlying land and ocean surfaces causing further warming and further melting
of ice and snow. The biggest uncertain factor in our knowledge of feedbacks is in how the properties of
clouds will change in response to climate change. Other feedbacks involve the carbon cycle. Currently the
land and oceans together absorb about half of the CO2 emitted from human activities, but the capacities of
land and ocean to store additional carbon are expected to decrease with additional warming, leading to faster
increases in atmospheric CO2 and faster warming. Models vary in their projections of how much additional
warming to expect, but all such models agree that the overall net effect of feedbacks is to amplify the
CO2-only warming by a factor of 1.5 to 4.5.
