"This sensitivity to warming suggests that without quantification of damage impacts by detailed physical models the (timing of) ice shelf retreat and Antarctic mass loss may currently be underestimated."

2nd or 3rd warmest November is in the books. Very warm anomalies almost all across the Northern Hemisphere. Negative Antarctic Oscillation with lots of extra warmth across Antarctica. Now lets see what December has in store. www.cpc.ncep.noaa.gov/products/pre... www.karstenhaustein.com/climate

Negligible contribution from aerosols to recent trends in Earth’s energy imbalance. While NH anthropogenic aerosols have decreased, enhanced emissions from wildfires and volcanic activity in the SH have produced comparable increases, yielding little net global impact www.science.org/doi/10.1126/...

New paper out in @natcomms.nature.com : doi.org/10.1038/s414... Aircraft contrails that form within existing cirrus clouds can add a measurable contribution to the overall contrail cirrus climate impact (which is a net warming effect). Combining aircraft position data with height-resolved... (1/2)

The costs of Direct Air Capture will not fall as much as hoped. "Efforts to reduce carbon emissions should therefore* continue at pace, says the research team." *Therefore is problematic here, as it implies that if DACCS was cheap less reductions are needed. No, no, no. ethz.ch/en/news-and-... 1/

Global trade could lose $14B/yr from disruptions at maritime chokepoints like the Suez and Bab el-Mandeb. New ECI study shows how conflict, piracy & extreme weather ripple through supply chains. By Dr Jasper Verschuur, Dr Johannes Lumma & Prof Jim Hall. ➡️https://tinyurl.com/96amj8sz

"The cost of removing large quantities of CO2 from the air will fall in the medium term, but not as much as previously hoped. This is the conclusion reached by @ethz.ch researchers on the basis of new calculations. Efforts to reduce carbon emissions should therefore continue at pace"

Extreme day-to-day temperature swings are becoming more frequent and intense due to Global warming, impacting human health, ecosystems, and resilience. By 2100, these changes could increase by 17%, affecting 80% of the global population. www.nature.com/articles/s41...

Now that we are likely to cross 1.5°C, there is increasing discussion on "overshoot". There is a lot of uncertainties on overshoot, but there is one thing that we are 100% sure about: GHG emissions need to go down >90% in decades for overshoot to be a reality. www.swp-berlin.org/publikation/...

The other certainty about overshoot is that even if we eventually get back to 1.5°C, a lot more people will suffer because we didn’t reduce emissions earlier and more rapidly.

Climate change is bad.

Two years ago, we did a study on a devastating drought in the Fertil Crescent. Due to climate change and water governance disputes the drought is still ongoing. Teheran might be running out of water, if it doesn't start raining soon. Our update: www.worldweatherattribution.org/human-induce...

Where are global CO2 emissions heading? Middle-of-the-road? But just because we have followed the SSP2-45, SSP4-60 path for 10 years, does not mean we follow it for the next 70 years. Policy & technology have pushed the world away from the high-end, but 2.7C in 2100 & rising is not a good outcome!

As well as protecting health, China’s efforts at cleaning up aerosol particle pollution has restored sunlight to Pacific Ocean, once robbed by the haze that was artificially brightening clouds, which unfortunately adds to warming - @uk.theconversation.com podcast: theconversation.com/how-china-cl...

Important new paper shows that mass casualties from extreme heat are likely at the current level of global warming and will only get worse the more the world warms: “mass mortality events remain plausible at near-future temperatures despite current adaptations to heat” www.nature.com/articles/s41...

ECMWF ensembles continue confident we'll get at least very close to a Sudden Stratospheric Warming (SSW) by the end of the month, although the surface impacts will depend on the details of the event (and a significant dash of randomness).

If we do not seriously move away from burning fossil fuels, hurricanes like Melissa will only become worse. Already today Melissa tested the limits of what preparedness and adaptation can do. These limits are very real for everyone in the Caribbean. www.worldweatherattribution.org/climate-chan...
