[Dr. Genevieve Guenther (she/they) 🪬 @DoctorVive]

If the world keeps using fossil fuels, one day the planet will keep heating up even if we stop using them.

Moreover, “the risk of crossing tipping points…increases with every tenth of a degree, starting with thresholds as low as 1.5 degrees of warming.”

End fossil fuels now.

[Ben See @ClimateBen]

CLIMATE SCIENTISTS: "The speed with which our once stable climate is falling apart is just astonishing, and very, very, scary. Maybe not that surprising when you consider that our world is heating faster than at any time across the 4.6 billion year geological record".

@BjornLomborg Most of the basic physics was right, unlike the rubbish from Limburg

[Sen. Bernie Sanders @SenSanders]

Trump believes climate change is a “hoax,” and he and his Big Oil friends want more fossil fuel and carbon emissions.

Meanwhile, the planet is warming at dangerous levels and Europe is facing a record-breaking heatwave.

We must break our fossil fuel addiction & save the planet.

@BjornLomborg This is a denier account from a non-scientist

[Marc Jones @MarcEHJones]

Many of the people flippantly dismissing the serious threat of global warming will eventually blame scientists for not being persuasive enough earlier.

People are spreading utter twallocks about climate change on here. The reality is that although climate change cycles are natural, we are vastly speeding up the process towards warming and have been since industrialisation.

Natural climate cycles happen very slowly. We are talking thousands of years. That enables life on earth to adapt. What is happening now is not giving us time to adapt.

Fossil fuel emissions are a main driver.

🚨NEW: Federal Judge Leonie Brinkema has blocked Donald Trump’s $1.8 billion “anti-weaponization” slush fund to pay January 6th insurrectionists.

RETWEET to thank Judge Brinkema for standing up for our democracy!

[Amelia Forest @greenheroaf]

What matters is the rate of change now, not a graph over millions of years. Ecosystems, biodiversity and communities are being hit within decades.

Tony Blair might not like my plan, but he's wrong: it's changing Britain for the better.

[Geoffrey Lean @GeoffreyLean]

For decades sceptics cited lack of melting of Antarctic ice as proof the world was not hearing up. But since 2015 it has been vanishing far faster than scientists expected. Now a new study suggests it may spark a new climate tipping point.

@JohnCrookes7 I had noticed this on the bbc, but less so on ITV

[Matthew Todd 🌏🔥 @MrMatthewTodd]

Sometimes I’m just shocked and awed that THE CLIMATE IS BEING CHANGED BY HUMAN ACTIVITY.
It’s stunning. How has humanity allowed this to happen? How the hell did hundreads of millions of people not rise up? Where on earth are the media and politicians?
It’s incomprehensible.

[Chris Gloninger, CCM, CBM @ChrisGloninger]

They call climate scientists grifters. Let me show you who's actually getting paid.

I make zero doing this. Average climate scientist: $95K a year. ExxonMobil's CEO: $33 million. One workday of his salary equals a full year of theirs. Find the scientists doing this work. Follow them. Share their content. Support them if you can. The fossil fuel industry has billions for PR. We have each other. Follow for more.

[Simon Maechling @simonmaechling]

A scientific consensus isn't a group of scientists agreeing.

It's repeated results from independent studies all pointing the same way.

We don't agree vaccines saves lives.

We know - because study after study shows it.

Consensus = consistent evidence.
Not collective opinion.

[Cormac O Rafferty @CormacORafferty]

@thematrixb0t Rubbish, co2 is unquestionably a forcing mechanism (as well as a feedback )

[Chris Gloninger, CCM, CBM @ChrisGloninger]

Feldman et al. (2015, Nature): direct spectroscopic measurement of CO₂'s radiative forcing at Earth's surface. Real photons, no models - ~0.2 W/m² per decade, matching theory to the watt.

Tyndall demonstrated the physics in 1859. Satellites confirm the fingerprint from orbit. You're not skeptical of models. You're skeptical of instruments.

[Matthew Todd 🌏🔥 @MrMatthewTodd]

When it comes down to it there is not one issue more important than this and it’s largely ignored by everyone on all sides
