#RealClimate
Wie viele der “Klimaskeptiker”, die meinen alles besser zu wissen als die Fachleute, hätten die Sonnenfinsternis korrekt vorhersagen können?
Die Erderwärmung entwickelt sich seit einem halben Jahrhundert wie auf Basis der Physik vorhergesagt.

If you see one of the diagrams on the internet that supposedly disprove #globalwarming or climate models, they invariably are aimed at lay people and don’t hold up under scrutiny. 🧐
Here’s another example (a cherry 🍒 pick) by notorious Roy Spencer debunked.

Did you know what causes Ice Ages?
It is the Earth’s orbital cycles, known since Milanković computed them in the 1920s.

When you drive a climate model with these cycles, it will correctly reproduce the sequence of Ice Ages as we know it from paleoclimate data.

Skillful weather forecasting, along with the increased preparedness it allows, is a landmark achievement of not only the US but of the human race. There are few other fields in the sciences where skillful prediction has had such an immense impact on our society.

Here's my thoughts on the latest round of discussion about the slowing of the Atlantic overturning circulation. It's a bit nerdy - but the short summary is: in my view the balance of evidence strongly suggests that the #AMOC has slowed since the late 19th C. 🌊
www.realclimate.org/index.php/ar...
RealClimate: The AMOC is slowing, it’s stable, it’s slowing, no, yes, …
RealClimate: There's been a bit of media whiplash on the issue of AMOC slowing lately - ranging from the AMOC being "on the brink of collapse" to it being "more stable than previously thought". AMOC, of course, refers to the Atlantic Meridional Overturning Circulation, one of the worlds major ocean circulation systems which keeps the northern
