There’s one key takeaway from last week’s IPCC report

Cut carbon pollution as much as possible, as fast as possible — The Paris climate agreement set a target of no more than 2°C global warming above pre-industrial temperatures, but also an aspirational target of no more than 1.5°C. That’s because many participating countries – especially island nations particularly vulnerable to sea level rise – …

Pollution is slowing the melting of Arctic sea ice, for now

Human carbon pollution is melting the Arctic, but aerosol pollution is slowing it down — The Arctic is one of the “canaries in the coal mine” for climate change. Long ago, scientists predicted it would warm quicker than other parts of the planet, and they were right. Currently, the Arctic is among the fastest-warming places …

Slowdown of Atlantic conveyor belt could trigger ‘two decades’ of rapid global warming

A slowdown in the Atlantic Ocean current bringing warm water up to Europe from the tropics could trigger “a period of rapid global surface warming”, a new study suggests — The research, published in Nature, says that a recent weakening of the “Atlantic Meridional Overturning Circulation” (AMOC) is coming to an end, but will stay …

Rising ocean waters from global warming could cost trillions of dollars

We’ll need to mitigate and adapt to global warming to avoid massive costs from sea level rise — Ocean waters are rising because of global warming. They are rising for two reasons. First, and perhaps most obvious, ice is melting. There is a tremendous amount of ice locked away in Greenland, Antarctica, and in glaciers. …

Flooding from sea level rise threatens over 300,000 US coastal homes – study

Climate change study predicts ‘staggering impact’ of swelling oceans on coastal communities within next 30 years — Sea level rise driven by climate change is set to pose an existential crisis to many US coastal communities, with new research finding that as many as 311,000 homes face being flooded every two weeks within the next …

Should we be worried about surging Antarctic ice melt and sea level rise

Short answer: maybe — There’s recently been a spate of sea level rise denial in the conservative media, but in reality, sea level rise is accelerating and melting ice is playing an increasingly large role. In the first half of the 20th Century, average global sea level rose by about 1.4 millimeters per year (mm/yr). …
