From a link in Little Green Footballs, one approach to the climate change problem:

There was a time when climate change was not a political football. This might be a way back there.

Humanity risks "unthinkable damage" on global warming, U.N. warns in new report
Here on the North Fork it won't take very much sea level rise to make Orient and Greenport into islands. Orient is attached by a 250 foot wide sandbar. Greenport is attached by a 450 foot wide section of beach, parking lot and roadway.

Trump administration sees a 7-degree rise in global temperatures by 2100
(And has no plans to do anything about it...)
Last month, deep in a 500-page environmental impact statement, the Trump administration made a startling assumption: On its current course, the planet will warm a disastrous seven degrees by the end of this century.

A rise of seven degrees Fahrenheit, or about four degrees Celsius, compared with preindustrial levels would be catastrophic, according to scientists. Many coral reefs would dissolve in increasingly acidic oceans. Parts of Manhattan and Miami would be underwater without costly coastal defenses. Extreme heat waves would routinely smother large parts of the globe.

But the administration did not offer this dire forecast, premised on the idea that the world will fail to cut its greenhouse gas emissions, as part of an argument to combat climate change. Just the opposite: The analysis assumes the planet’s fate is already sealed.
:snippity:
The world would have to make deep cuts in carbon emissions to avoid this drastic warming, the analysis states. And that “would require substantial increases in technology innovation and adoption compared to today’s levels and would require the economy and the vehicle fleet to move away from the use of fossil fuels, which is not currently technologically feasible or economically feasible.”

The report of the IPCC panel is being read as if a step function describes climate change: act responsibly within the next 12 years and your planet will remain habitable. .

There may well be step functions in climate change -- collapse of the Ross Ice Shelf comes to mind. But the IPCC panel is not tellng us that everything will be pretty much like today if we just act within 12 years. It is tellng us that if we persist in business as usual, within 12 years things will be pretty rough.

Understanding climate change projections requires understanding that changes in mean global temperature are not saying that change will be uniform around the planet. Instead, some places will be at the end of the distribution -- much warmer or for some, (yes) cooler. Not everybody is ready to understand variance, skewness, and kurtosis. They might be thinking that IPCC is saying we should expect a global temperature increase about the same as the difference between Key West and Miami. So why all the excitement? It is because change will be much more pronounced in some places.

"I love a sunburnt country,
A land of sweeping plains
Of ragged mountain ranges
Of droughts and flooding rains.
I love her far horizons
I love her jewel-sea,
Her beauty and her terror –
The wide brown land for me!"

Except from: My Country by Dorothea Mackellar 1908

I rather that it didn't get more unpredictable!

Oh and if you think it is just your government that is wanting to embrace a 2nd dark age of ignorance and fear of cause and effect then you are not alone..

News about climate change has grown increasingly bleak in recent weeks. Now, scientists have acknowledged their predictions on the regional effects of climate change are flawed and things could be far worse than they previously expected. http://ow.ly/mH7Z30mgaQz
In fact, the researchers say their simulations show exactly the opposite – slightly decreasing air pressure. The findings raise serious doubts as to the accuracy of climate predictions for the United Kingdom and Western Europe, since their weather is closely linked to pressure changes over Greenland.

Climatologists believe record wet summers across England like those experienced in 2007 and 2012 could become commonplace if the Greenland blocking pattern continues to strengthen. However, no one will see it coming because of the faulty simulation programs, the researchers said.

“These differences between the estimates from the current climate models and observations suggests that the models cannot accurately represent recent conditions or predict future changes in Greenland climate,” said lead researcher Edward Hanna of the University of Lincoln’s School of Geography. “While there is natural variability in the climate system, we think that the recent rapid warming over Greenland since the early 1990s is not being fully simulated by the models, and that this misrepresentation could mean that future changes in atmospheric circulation and the jet stream over the wider North Atlantic region may not be properly simulated.”

Making the situation even more dire, the researchers have also concluded current models of melting on the Greenland Ice Sheet – which covers 80 percent of the surface of the world’s largest island – may be flawed as well, and may significantly underestimate how much sea levels will rise by 2100.

The Guardian
Politicians say nothing, but US farmers are increasingly terrified by it – climate change

Research forecasts Iowa corn yields could drop in half within the next half-century thanks to extreme weather – yet it’s not part of the political conversation ...


It’s the least debated issue of the midterm political season. The weather is the top topic of conversation at any cooperative elevator’s coffee table, along with the markets. Everyone knows that things have been changing in sweeping ways out here on the richest corn ground in the world. It’s drought in the spring and floods in the fall – what were considered 500-year floods in Cedar Rapids and Des Moines 30 years ago are now considered 100-year floods. Iowa has been getting soggier in spring and fall, with scary dry spells interspersed, and more humid at night by as much as a third since 1980.

Everyone knows it has been getting wetter and weirder, especially Dr Gene Takle, a Nobel prize-winning climate scientist at Iowa State University. Takle predicted 20 years ago the floods we see today, already linking it to climate change back then. Farmers just saw ponding and called the tiling company to install more. We’re on our way to doubling the size of the northern Iowa drainage system in the past 30 years as the upper midwest has grown more humid and extreme.

This drainage system is delivering runoff rich in farm fertilizer to the Mississippi river complex and the Gulf of Mexico, where the nitrate from Iowa and Illinois corn fields is growing a dead zone the size of New Jersey. The shrimping industry is being deprived of oxygen so Iowa farmers can chase 200 bushels of corn per acre – and hope against hope that corn will somehow increase in price as we plow up every last acre.

That flow also is creating a toxic source for Des Moines Water Works, which is facing up to $100m in improvements to remove agricultural chemicals from the Raccoon river that supplies 500,000 thirsty denizens. The waterworks sued our county over it, along with two others, but a federal judge threw out the case because you simply can’t sue an Iowa drainage district. And that means that there is no way to regulate agriculture as it responds to extreme weather and market consolidation that seeks immediate return.

Meanwhile, those huge rainfalls on exposed black dirt wash it to the vales even from the flat ground of our neighborhood. We are losing soil at two to three tons an acre a year. Nature can regenerate the soil at only a half-ton a year. So we are washing our black gold down the river four to six times faster than we can regrow it.

This is not good news. (Is there ever any good news about the world's climate?)

Climate change: Oceans 'soaking up more heat than estimated'


According to the last major assessment by the Intergovernmental Panel on Climate Change (IPCC), the world's oceans have taken up over 90% of the excess heat trapped by greenhouse gases.

:snippity:

"A warmer ocean will hold less oxygen, and that has implications for marine ecosystems," said Dr Resplandy.

"There is also sea level, if you warm the ocean more you will have more thermal expansion and therefore more sea level rise."

:snippity:

"When the ocean warms, the amount of these gases that the ocean is able to hold goes down," said Dr Resplandy.
Also, warmer oceans mean more powerful storms.

I thought we had a separate thread on the topic of the lawsuit brought by Our Children’s Trust, but I can't find it. :crying:

Here's the good news:
BREAKING: High Court Removes Red Light For Kids' Climate Trial
The U.S. Supreme Court late Friday lifted a stay on a suit brought by 21 children accusing the federal government of pushing policies that will worsen climate change-related dangers, clearing the way for a landmark constitutional trial to begin in Oregon federal court but also leaving room for the Ninth Circuit to decide the case's future.
From an email, so no linky.
