ClimateChangeNForum

A national forum on climate change, founded & led by an open commnty of scientists & journalist; nonprofit & website ceased in '16, but fmr board mbrs tweet on.

There's more happening to weather extremes now than can be explained by thermodynamics, i.e. everything getting warmer, evaporation increasing, the atmosphere holding more energy and water.
Also changing: jet stream, polar vortex, planetary waves & Atlantic ocean circulation.

It’s the year 2023. The IPCC has stated that it is unequivocal that humans are causing global warming.
So why do some event organizers still invite science deniers on stage to spread their misinformation about #climatechange?

[Bart Verheggen @BVerheggen]

Cities are warmer then the surrounding areas.
But this so-called Urban Heat Island effect has a negligible impact on our estimate of global (!) warming, despite claims to the contrary by a group of well-known contrarians.

What every climate scientist will tell you:

Record-breaking extreme weather events of 2023 are expected at this level of warming.

The impacts on people are more severe than expected.

To keep things from getting worse, we need to stop burning fossil fuels & speed up adaptation.

[Zeke Hausfather @hausfath]

Global CO2 emissions are flattening. Thats good news, and reflects real progress in the energy transition.

But a flattening of emissions just means the world will continue to warm at its current rate, rather than accelerating. To stop warming, we need to get emissions to zero.

[Bart Verheggen @BVerheggen]

Global warming is projected to substantially increase the mortality burden attributable to non-optimal temperature. Higher global temperatures only lead to minor decreases in cold-related mortality which do not offset increases in heat-related mortality.

TBH, this seems worse than having the road blocked by climate activists for a few minutes.

[Leon Simons 🌍 @LeonSimons8]

🌏Earth is a complex system.🌐

Most people think of global warming as increasing Global Mean Surface Temperatures (GMST), as used for climate targets.
This makes sense, because we live on the surface.

But the vast majority of the additional heat is stored in the ocean depths:

Cats 🐈‍⬛ 🐈 kill 1.85 billion birds 🦜🕊🪶 every year in the #US

But no calls for cats to be banned

Buildings 🏢 kill 675 million birds

Vehicles 🚛🚙 214 million birds

We poison ☠️ 72 million birds

Wind turbines kill just 328,000 and #climatechange deniers want to ban them!

The truth in this joke.

decade will have impacts now and for thousands of years"
#IPCC Synthesis Report
@piersforster clearly states the urgency: "This is the critical decade, but we're not yet taking critical action."

The Swiss Alps had a disastrous year in 2022, losing 6% of the glacier ice volume.
This winter has been even worse.

"Our analysis of nearly 100 million carbon credits found that only a fraction of them (6%) resulted in real emissions reductions.
94% of those credits are likely to be worthless, the calculations showed." #offsets #Verra

Since the late 1970s, ExxonMobil’s own scientists accurately projected and modeled global warming due to fossil fuel burning and produced results that were consistent with independent academic and government climate models, a new #ScienceReview finds. https://t.co/eJLLBNNZ3W

[UN Biodiversity @UNBiodiversity]

If you’re wondering:

✅ What is COP15?
✅ Why is COP15 so important?
✅ How does COP15 aim to protect nature?
✅ What is in the draft agreement?
and many more questions,

You should go read @pgreenfielduk’s article by the @guardian ⬇️🌿

33 years ago UK Prime Minister Margaret Thatcher warned the world of #climatechange

A scientifically trained right wing liberal urged governments of the world to deal with it - collectively

Climate change deniers, fossil fuel lobbyist, neoliberals ignored her so #ClimateCrisis

[ClimateActionTracker @catclimate.bsky.social @climateactiontr]

The emissions gap to 2030 remains the challenge, one that governments must do everything they can to meet if we have any chance of limiting warming to #1o5C. It’s all still possible, but time is of the essence.

[ClimateActionTracker @catclimate.bsky.social @climateactiontr]

Massive gas expansion risks overtaking positive climate policies. Our COP27 global update finds govts' focus on energy crisis has replaced #ClimateAction. Proposed, approved & under-construction #LNG projects globally likely to send emissions way past 1.5. https://t.co/QdA55UegpC

[UN Environment Programme @UNEP]

Out now: the latest edition of the @UNEP #EmissionsGap Report sounds the alarm for urgent, large-scale transformation to avoid climate catastrophe.

"Climate disruption has changed the background conditions in which all weather occurs: the oceans and air are warmer, there’s more water vapor in the atmosphere and sea levels are higher. Hurricane Ian is the latest example."
