25 Years of Satellite Data Shows Global Warming Is Accelerating Sea Level Rise (usnews.com)

An anonymous reader quotes a report from The Associated Press: Melting ice sheets in Greenland and Antarctica are speeding up the already fast pace of sea level rise, new satellite research shows. At the current rate, the world's oceans on average will be at least 2 feet (61 centimeters) higher by the end of the century compared to today, according to researchers who published in Monday's Proceedings of the National Academies of Sciences. Sea level rise is caused by warming of the ocean and melting from glaciers and ice sheets. The research, based on 25 years of satellite data, shows that pace has quickened, mainly from the melting of massive ice sheets. It confirms scientists' computer simulations and is in line with predictions from the United Nations, which releases regular climate change reports. Of the 3 inches (7.5 centimeters) of sea level rise in the past quarter century, about 55 percent is from warmer water expanding, and the rest is from melting ice. But the process is accelerating, and more than three-quarters of that acceleration since 1993 is due to melting ice sheets in Greenland and Antarctica, the study shows.

    No longer adding NEW COAL plants will not lead to any issues. In fact, it would likely increase the lifespan of more citizens.
    As to cutting coal, far better to simply replace those with AE and Nukes.
    And I fully agree with your last bit there.
    Right now, the ENTIRE WEST puts out less CO2 than what China is adding JUST IN COAL PLANTS over the next 10 years.

    Economic rules are not the same as physical laws. Physical laws exist regardless you believe in them. Economic rules are human rules. They can be changed. For example you can lower taxes for the rich or deprive people of healthcare. You can even make up rules to limit the ability what you can dobwithnyour money. And even money itself is just a number or a piece if paper. Its value is based in an agreement. Look I have billions of Reichsmark in my attic. Unfortunately, you cannot buy anything with it. You can also see the artificially of value of currency in context of bitcoin.

    Yes because somewhere someone else is producing 1/5th of the emissions per capita of the people in the USA it is all *their* fault and we can't do anything.
    "America First! ... in emissions per capita".

    Per capita is meaningless in relation to *TOTAL GLOBAL* levels. But you likely already know that and are simply hoping you can blow it by others because 'muh Party!'.

    Australia has a very high CO2 per capita average, but a small total population so the total amount of CO2 Australia contributes is small. China and India have a low per-capita average but enormous populations, so they contribute a large percentage of the total CO2 released. Sort of a CO2 emission "economy of scale'.

    China, India, and other developing nations are producing more total CO2. The US cannot make up for their increases even if the US reduced CO2 emissions to zero. If the US stops trading heavily for consumer goods with china then their economy goes in the crapper, their budget for infrastructure will shrink, and new power plants will be coal and CO2 emissions will then begin to increase even more rapidly.

    The annual deep frost would kill so much of the weeds and the bugs. As the climate changes, the USDA agricultural zones are changing. What used to be 3 is now 4 etc. Weeds that were killed every winter and start from the scratch, survive the winter, start early and spread fast. They even get two or three more generations per season.

    The bugs too, are surviving winter. The most ardent climate change denying, conspiracy theory believing, Iowa farmer sees the forsythia blooming in February, tulips emerging in March, crocus in December... Some fields naturalized by daffodils and tulips are going the other way. The bulbs rotting away instead of emerging. These bulbs need six weeks of continuous freezing for them to "sense" the coming and going of winter. Without the frost, they dont emerge and they rot in spring rains.

    One of the most productive agricultural belt is protected by annual frost. It has no natural defense against many of the deleterious organisms. All it takes is one fungus, one virus, one weed to afflict the Idaho potato crop or the corn or wheat... By the time we identify and mitigate the threat we would have lost two or even three years of loss of agricultural productivity. Affluent USA will suck the products from rest of the world, prices will shoot up beyond belief. Poor countries with unstable regimes will see societal collapse, mass migrations and refugees...

    These consequences are far more dire, far more urgent than sea level rise. Sea level rise is important it will lead to very serious climate changes. But that is very indirect and direct cause - effect relations difficult to deduce, difficult to prove, difficult to explain to public.

    If ppl want to stop this, then ALL NATIONS MUST STOP. Not just 1 or 2.

    And that will never happen. I see a lot of talk about China in this thread but Russia is the #2 emitter of pollution. The US is reducing emissions, both per-capita and overall. Russia's emissions per GDP are increasing (albeit not as rapidly as China). Here's a nice graph of emissions per capita for the top 3. The difference is that China is seeing a lot of negative effects related to pollution, and politicians are under pressure to fix the problem or risk destabilizing the country. China has incentives to act.

    Russia, on the other hand, doesn't have many developed low-lying coastal areas. Weather patterns are becoming more habitable, arable land is increasing, icecaps limiting shipping are melting, more natural resources (fishing, oilfields, etc) are becoming accessible, etc. Climate change may cost Russia's economic competitors in both money and political stability. A decent chunk of the Russian economy is based on oil and natural gas exports. Many other countries have some of these incentives, but Russia is the big winner of climate change, and they have every incentive not to take action. I would not be at all surprised if Russia was actively promoting anti-climate change ideology. They have a strong motive, means, and opportunity.
