Even if humanity were to stop throwing carbon dioxide and methane into the atmosphere today, a catastrophic rise in sea levels of six meters may be inevitable. Two previous prehistoric interglacial periods, in which the carbon dioxide content of the atmosphere was believed to be about what it is today, resulted in dramatic rising of the oceans. High-latitude ice sheets …
World’s Oceans Could Rise Higher, Sooner, Faster Than Most Thought Possible – Jon Queally
If a new scientific paper is proven accurate, the international target of limiting global temperatures to a 2°C rise this century will not be nearly enough to prevent catastrophic melting of ice sheets that would raise sea levels much higher and much faster than previously thought possible. “Parts of [our coastal cities] would still be sticking above the water, but …
Global sea levels have risen six meters or more with just slight global warming
A new review analyzing three decades of research on the historic effects of melting polar ice sheets found that global sea levels have risen at least six meters, or about 20 feet, above present levels on multiple occasions over the past three million years. What is most concerning, scientists say, is that amount of melting was caused by an increase …
Panel of international climate scientists says the world has only until 2050 to become a zero-carbon society − but the rewards for doing so would be immense. – Alex Kirby
If you want to know what we have to do to avoid catastrophic climate change, 17 of the world’s leading climate scientists have worked out a simple but challenging solution: the world, they say, must turn by mid-century into a zero-carbon society. The signatories to today’s “Earth Statement” say: “This trajectory is not one of economic pain, but of economic …
