According to the UN, current national policies lead to about 2.8 °C (5.0 °F) of global warming by 2100.
But many areas will warm faster. For Germany, it would mean about +4.6 °C (8.3 °F).

Global warming emissions are a diverse problem driven by all sectors of human activity.
Some sectors are much easier to address than others, but an efficient transition to zero emissions will require many different solutions to be deployed in parallel.
“The human tragedy is that there is no connection between what we know and what we do. Almost everyone is now at least vaguely aware that we face the greatest catastrophe our species has confronted. Yet scarcely anyone alters their behaviour in response.” https://t.co/DdfKba9FTp
Because CO2 emissions are cumulative in the atmosphere, more than any museum, CO2 concentrations are the nearest representation of our cumulative collective efforts, over all of history, using combustion to survive from day to day

Wildfires, floods, droughts, heatwaves and other (un)natural disasters rage all over the world.
Many now ask "What will it take for people in power to act?".
Well, it will many things, but above all it will take: massive pressure from media and massive pressure from the public.
“Insect declines really became a topic of conversation when the German insect decline study was published, which showed this 76% decline… In the U.K., we have only got really good population data for butterflies, which are dying by 50% since 1976.” (1/x) https://t.co/tLf47bovMJ
1.2 million people have been affected by the flooding in China, with 200,000 now in emergency shelters. A year’s worth of rain fell in three days. https://t.co/XecJJGEhJY
@CharlieJGardner Writing this piece, after 20 years of toning down my own language to be more palatable, was a reminder that its time to dial up the temperature on the words we choose. https://t.co/1ocap0qoNY
Extreme weather is striking all over the world.
Some events — like wildfires sweeping the western US — are seasonal, while others came as a total surprise.
Here’s a look at what has happened this week. 👇 https://t.co/ipzPN91cuP
Unprecedented wildfires in Siberia have now burned through 3.7 million acres of land, destroying vast swathes of forest. We are in a climate emergency. https://t.co/GEeV9EeEFD
Pictured: The rapid collapse of sea ice in NE Siberia forces tens of thousands of walrus to crowd on the coastline.
The walruses used to forage on the ice, but now must swim a long way in search of food. Their numbers are also being depleted due to deaths caused by crushing.
“Global greenhouse gas emissions are likely to rise to record levels in the next two years, as governments fail to ‘build back better’ from the Covid-19 pandemic.”

Everyone, I think we can say that climate impacts are worse than we (scientists) expected at 1.2°C of global heating. While we did not say it was a "safe" level, others did, and I think we can now agree that it is not; and that this was a fatal flaw in the "carbon budget" framing
National Food Strategy: Prescribe vegetables, tax sugar and salt, says report. What about taxing the corporations selling the obesity junk? And tax the advertising agencies promoting unhealthy foods. https://t.co/wm30h72xD8
