Well worth watching. Otherwise, here's a summary thread 👇

The proof is ALL OVER THE INTERWEB 🧐

GLOBAL WARMING (as described by the Left) IS A HOAX and Being Used Against You As A Money Making Machine 🧐

I Have Posted this Many Times Before, but here YOU ALL go again INVESTIGATE IT

As 2020 comes to a close, we're taking a look back at some of our best reporting on the environment.

The American landscape has become 48 times more toxic to insects since the 1990s, a shift largely fueled by rising use of neonicotinoid insecticides.

Banned in the EU, a sophisticated information war has kept these insecticides on the U.S. market.

Amid California's severe wildfires, grape growers in Sonoma County got exemptions to send in farmworkers who have few alternatives or options for support into fire evacuation zones.

With Trump's election, a small and previously marginalized group of toxics apologists suddenly took control over health and environmental regulations, ushering in higher profits for polluters and higher cancer rates for the American people.

Steven Donziger won a multibillion-dollar judgment against Chevron in Ecuador. The company sued him in New York — as of December, he has been under house arrest for over 500 days.

There's a huge gap between what climate scientists are willing to say privately and what we're willing to say publicly, in terms of how dire a situation we're in. Colleagues, integrity demands we close this gap.

Fascinating new paper by @AndrewDessler and colleagues arguing committed warming might be higher than expected given historical pattern effects. Its combining a lot of different concepts together, so lets spend some time disentangling them https://t.co/ILi5z515Qy

A thread: 1/19

The paper's headline number is that we previously thought the world was committed to 1.3C warming, but that number is actually over 2C (> 1.5C by 2100). This is quite a different message than we get from Earth System Models, which suggest committed warming is only ~1.2C. 2/19

This would imply that the 1.5C by 2100 target is effectively impossible, and that long-term warming of >2C would be very difficult to avoid. However, the devil is in the details, and the picture is not quite as dire as it would seem at first glance. 3/19

When we talk about "committed warming" folks are generally talking about one of two scenarios: either constant CO2 and other GHG concentrations (and forcings), or getting all emissions (or just CO2 emissions) down to zero immediately. 4/19

In the first method – constant concentrations – we find that the world warms up another 0.5C or so, as the oceans continue to take up heat as more energy is being trapped by greenhouse gases than is being emitted back to space. Much of this additional warming happens by 2100 5/19

EU Summit just agreed a “binding EU target of a net domestic reduction of at least 55% in greenhouse gas emissions by 2030” - so UK going somewhat further at 68%...

That is in reference to 1990 carbon emissions - which is the standard point of reference

VDL trying to sound conciliatory - making point about the ratchet clause that all sides “remain free - sovereign” to do what they are want as regards matching future increases in regulations, but that both sides should retain right to adapt conditions for market entry

On fishing VDL says UK must understand legitimate expectations of EU fishing fleet based on decades and sometimes centuries of access ...

journalists at the EU summit seem more interested in asking Merkel/ VDL about Turkey than summit Brexit discussions, so far zero questions - some informational value there ...
