WMO's secretary general Petteri Taalas has been spreading false information related to #climatechange in Finnish media https://t.co/LW1lC2gkuB

Changes are emerging across the climate system. Everywhere we look, the climate is changing rapidly.
Rate of recent changes is unprecedented in at least 2000 years for many climate metrics.
These changes are not natural; they are primarily caused by the burning of fossil fuels.

Confirmation from new ice cores that central/northern Greenland temperatures are highest in past millennium & 1.5C warmer than 20th century, leading to increased meltwater runoff: https://t.co/7xFVcSUxaX

Skeptical Science team member @BaerbelW turned @GeoffreySupran's 🧵about the paper "Assessing ExxonMobil’s global warming projections" published with @rahmstorf & @NaomiOreskes into a quick blog post:

@MattBarna @hausfath Here are some research papers on that: https://t.co/2tYwJHtYgo

[Ari Jokimäki @AGWobserver]

@hausfath I heard first such claims already in 2018, and I wrote about it in this article: https://t.co/RrWQ2kCRZK

In light of the paper from @GeoffreySupran @rahmstorf @NaomiOreskes showing that Exxon predicted global warming extremely accurately between 1977 and 2003, this exchange between @AOC and Exxon scientists is worth revisiting.

[Geoffrey Supran @GeoffreySupran]

NEW: In @ScienceMagazine today, our latest peer-reviewed research shows Exxon scientists predicted global warming with shocking skill & accuracy between 1977 & 2003, contradicting the company's decades of climate denial. THREAD.

2022 was the 5th warmest year on record in our @BerkeleyEarth surface temperature dataset, and the warmest year on record for regions where 850 million people live.

28 countries saw their warmest year on record, including the UK, Spain, France, Germany, New Zealand, and China.

@Apocalypse4Real Oh, and by the way, I have recently done preliminary a similar check on the term "climate crisis" and that term has been in use in scientific literature at least from 1980s.

[Ari Jokimäki @AGWobserver]

@Apocalypse4Real ...which might have resulted in Broecker writing his 2017 article on this: https://t.co/qQ23SF8h6L
Note that I don't want to take anything away from Broecker. I have full respect for him and admire his work.

[Ari Jokimäki @AGWobserver]

@KenCaldeira @past_is_future @Apocalypse4Real @CColose @BaerbelW @FataMorgana_LS @theresphysics It's too bad that google books doesn't let you limit searches by publication year like Google Scholar does. That 1928 use of GW in a book would be interesting if it is real.

[Zeke Hausfather @hausfath]

Good article by Discover Magazine debunking three common climate myths (with help from @_david_ho_).

In short:
- Climate change is anthropogenic
- It’s not just a problem for future generations
- There is a lot we can do so mitigate it

In Finland, the government is targeting its clear-cutting to the old-growth forests which are candidates to become conservation areas. https://t.co/Ngald9IxcE

@DinahVP @MichaelEMann @kcrowebasspro @USATODAY Thank you. Seeing your piece in question, I just hope that there would be more journalists like you - if there were, maybe we even wouldn't have this problem. :-)
