Climate change - from CO₂ to crisis. It starts with accumulation of greenhouse gas emissions but leads to multiple global repercussions. Climate change isn’t a distant threat — it’s a systemic chain reaction already in motion & steadily increasing in severity.

"Climate-related disasters forcibly displaced 250 million people globally over the past decade, the equivalent of 70,000 displacements every day, according to a report by the UN refugee agency (UNHCR). The figure includes people who have been displaced multiple times." #ClimateCrisis

If you were born after 1976 — which is two thirds of humanity — you've never experienced a colder-than-average year.

That is, a year when the global mean surface temperature was below the 20th-century average (1901-2000 baseline).

"Methane is a greenhouse gas 80 times more powerful than carbon dioxide and is responsible for about a third of the warming recently recorded. Cutting it could be an “emergency brake” on global temperatures, but so far, countries have not taken the measures needed."

Yet another record breaking storm supersized by a warming world 😢

Climate change doesn’t create these storms: it makes them worse. They intensify faster, reach higher strengths and dump more rain.

That’s why climate action isn’t just about saving the planet: it’s quite literally about saving US.

Here's a look at the extent of the "warmth" across the #Arctic in October. This map uses my normal anomaly scaling for each month, but it clearly doesn't work for something this extreme.

Freedom to think or believe is something entirely separate from freedom to impose your thoughts or beliefs on others. If freedom is to mean anything, then government should protect not the right to impose, but the freedom from that imposition.

Trump just continually shooting our country in the face. This unwarranted (and likely illegal) destruction of Goddard is madness. It jeopardizes the next several decades of space exploration.
