The Trump Admin's repeal of the Endangerment Finding is brazen denial of climate science that puts polluters before people. We will continue to fight this in every way we can.

If all Earth’s ice sheets melted, sea level would rise ~65m over millennia
But just 1–2% of that (~65–130 cm) would force chronic flooding & retreat in many coastal cities
~1 billion people live within 10m of sea level (~15% of total)
The risk isn’t the end state, it’s how little change it takes!

The irony of ICE expanding and polar ice contracting is not lost on me. Naked fascism in an effort to control climate-driven migration in the US just wasn’t what I expected.

Anthropogenically-accelerated climate change is ultimately leading to a warmer Earth faster than is natural, but the process is one of chaos and instability, like our recent deep-freeze and snowfall in the U.S. and Canada.

Can global warming increase snowfall? Greater evaporation from warming oceans increases atmospheric water vapor. More water vapor increases total precipitation during many kinds of storms, including winter storms. Read our newest feature story for more. Link in comments.

If cooling caused the Late Ordovician extinction, the crash should have been smooth.
It wasn’t.
Something else broke the system.

The Ordovician Extinction Had a Plot Twist #paleontology #extinction #fossils
For a long time, the Late Ordovician extinction, about 513 million years ago, seemed simple.
The planet cooled, ice sheets grew, sea levels fell, and shallow seas disappeared.
That explanation works…

Truly one of the great conservation juxtapositions: Manatees enjoying the warm water effluent from a coal power plant during a cold snap caused by the prolonged breakdown in the polar vortex driven in part by the emissions of said coal power plant. Manatees living in a man made world

There’s no tipping point beyond which ocean acidification kills corals, new research shows. With every creeping bit of acidification, corals just continue to die off. 🧪🌊 eos.org/articles/cor...
Coral Diversity Drops as Ocean Acidifies - Eos
As seawater becomes steadily more acidic, complex branching corals die off and are replaced with hard boulder corals and algae.
