The Last Time the Earth Was This Hot — Here’s What the Ocean Did

The last time the earth was this hot — here’s what the ocean did

Sea levels will rise — by metres, not centimetres — and the time to prepare is now. Drawing on ancient clues and the latest science, Johanna Wagstaffe explains what Earth’s past reveals about our coastal future — and why smart planning today could protect millions in the decades and centuries to come.

The ice cover in the Arctic is melting at an alarming rate, followed by rising sea levels, but coastal cities cannot build defenses as quickly.

Sea Level Rise Will Cause ‘Catastrophic Migration,’ Scientists Warn - WhoWhatWhy

Sea Level Rise Will Cause ‘Catastrophic Migration,’ Scientists Warn (Maria) The author writes, “Sea level rise will become unmanageable at just 1.5 C (34 F) of global heating and lead to ‘catastrophic inland migration,’ scientists behind a new study have warned. This scenario may unfold even if the average level of heating over the last decade of 34 F continues into the future. The loss of ice from the giant Greenland and Antarctic ice sheets ha…

International research raised alarms about the future of many of the world's coastal cities. China's Institute of Environmental Sciences revealed that if urgent action is not taken, rising sea levels could leave several of the planet's major cities underwater by 2050.The main cause is the melting of poles and the sustained rise in global temperatures, driven by greenhouse gas emissions. According to experts, if emissions are not reduced and adap…

Michael Haworth: Dangerous days

I’m 79 years old and have come to a realization. More on that in a minute. I was reading an article that produced the following from NASA: “For the first time ever, the rising ocean waters of the world, up an astounding .23 inches in 2024 instead of the expected .17 inches, which is bad enough, are now more the result of thermal expansion, rather than melting glaciers.” The NASA article mentioned “difference makers,” and we have plenty of them. …

If the Earth warms by 1.5 degrees Celsius, it will lead to uncontrollable sea level rise, causing a “catastrophic migration inland,” the authors of a new study warn, but they note that their models suggest this could happen even if temperatures are kept below 1.2 degrees.
