Open access notables Back in April of 2020 Chi Xu et al. captivated some public attention with their paper Future of the human climate niche,  which explained a reasonable case for its startling conclusion about routine habitability of large parts of our planet now supporting dense populations. Now come the same researchers along with added talent to refine and extend those results, and the news isnt getting better. Quantifying the human cost of global warming paints a grim p...

Open access notables Multiple studies indicate changes in the properties of Antarctic bottom water (AABW) over the past half century. These changes involve density and hence will affect both local and distant circulation of the oceans, not least overturning effects that are vital for marine biology but also climate and weather far distant from Antarctica and the Southern Ocean. While we can see whats happening, our understanding of whats driving change is incomplete. By synthesizing multiple obs...

Open access notables Visiting online haunts of climate science rejectionists reveals a nexus of anxieties in some sections of the public: climate change and population migration. Judging from connections formed in headlines and article texts, one could easily conclude that readers fears are being exploited; its not hard to find content implying that the concept of climate change is a subterfuge to justify opening borders to foreigners. Given what we know of developing physical effects of cl...

Open access notables The Intelligence Community Must Evolve To Meet the Reality of Arctic Change is a product of the Wilson Centers  subject specalist center The Polar Institute. As its title suggests the report is squarely centered on nitty-gritty details of geopolitical adaptations forced by climate change as theyre reflected in national security matters, here (unsurprisingly given the Wilson Institutes mission and purpose) specifically the security of the United ...

A climate reconstruction study published in the ‘Global and Planetary Change’ finds that warm and cold climatic spells in the Arctic, over the past 1000 years, imprinted on India’s monsoon fluctuations during that period, as highlighted by a Mongabay-India report. The report says that the frigid Arctic is a key indicator of the ongoing

Open access notables Despite the potential for positive methane–climate feedbacks from global wetlands, most Earth System Models (ESMs) and Integrated Assessment Models (IAMs) that informed the last Assessment Report of the IPCC do not directly incorporate this process. Publishing in Nature Climate Change, Zheng et al. unpack the implications of this oversight in Recent intensification of wetland methane feedback. The authors find that compared to climate models CH4 emi...

Thwaites is melting slower than thought, but the worst of it is concentrated in underbelly cracks, threatening the Antarctica glacier’s stability.
