  After listening to today's coverage of #weather records, #drought and #wildfires on #BBC radio and TV news programmes I can't help wondering if BBC news and weather presenters are working under a directive not to mention the link between these things and anthropogenic #climate change. Isn't it a normal journalistic question to ask what is causing these things and what we can expect in future years?

  The “Eternity Glaciers” Are Almost Gone The equatorial glaciers atop Puncak Jaya, Oceania’s tallest peak, have shrunk by about 95% since 2002, according to a new photogrammetry mapping effort. https://eos.org/articles/the-eternity-glaciers-are-almost-gone

  If you'd like to find out what recent research has revealed about Antarctica's Thwaites Glacier and what this means for future sea-level rise, this is a good place to start. Great overview in New Scientist by Alison George. https://www.newscientist.com/article/2526630-the-race-to-understand-how-and-when-thwaites-glacier-will-collapse/

  It is now late autumn in Antarctica. The polar night, when the sun disappears below the horizon until spring, will soon extend over most of the continent. Yet there is still hardly any sea ice in the southern Bellingshausen Sea (lower left in the regional map below). Sea ice concentration maps are from the Institute of Environmental Physics, University of Bremen, Germany - https://seaice.uni-bremen.de/sea-ice-concentration/amsre-amsr2/

  Recent results indicate that its too late to save Thwaites Glacier, the Antarctic glacier that's losing ice most quickly. Its fate is now baked in, although further research is still needed to establish the timeframe over which it will be lost. Technofixes ("geoengineering") intended to slow its ice loss are not a viable option to combat sea-level rise though. They would be phenomenally expensive (of the order of the GDP of a medium-sized country), might have limited ef...

  So Artemis II achieved a record-breaking maximum distance of 252,756 miles (406,771 km) from Earth. This compares to 248,665 miles (400,171 km) attained by Apollo 13. With the benefit of more than 50 years of technological advancement that's an increase of just 1.65%. Can we stop hearing about this as one of the stand-out achievements now please?

  I'm as fascinated by the Artemis II mission as many other people, but as scientist I'm frustrated that experts interviewed about it in the media are rarely asked to justify the truly astronomical cost. So far the program is reported to have cost $93Bn, with the direct costs of this mission alone amounting to more than $4Bn. I'm perhaps particularly sensitive to this because I'm frequently asked to justify funding three orders of magnitude smaller that we have used...

  The feeling right now of every scientist trying to communicate the seriousness of ongoing global warming and the urgency of reducing emissions. Excerpt from a cartoon by the late Jon Kudelka.
