Excited to share a preprint from the VulcanInc Climate Modeling ML team. "Correcting weather and climate models by machine learning nudged historical simulations" essoar.org/doi/abs/10.100… Idea: machine learn corrective tendencies to improve a coarse-resolution GCM🌐

Our new AGU (American Geophysical Union) GRL study is now out. We investigate the 'Recent Emergence of Arctic Amplification' in the past century of the observational record. Using a large ensemble, we explore why Arctic Amplification didn't occur for much of the past century doi.org/10.1029/2021GL…

JUST LAUNCHED: Making your own temperature projections in line with IPCC WG1 science? New portal: live.magicc.org BTW: MAGICC is temperature engine behind UN Environment Programme gap report, International Energy Agency 1.8C assessments, our 1.9C NDC analysis (climate-resource.com/tools/ndcs) and 2.4C by CAT

A bit mysterious for me how pledges are easily translated into temperature targets. Countries don’t report GHG sinks and sources in unmanaged lands. What if those lands which are C sinks today weaken their C uptake or increase their natural emissions (permafrost, wetlands CH4) ?

Quite an amazing source of information ! Note : Van den Ent et al. also found a rather similar rain recycling pattern across S America agupubs.onlinelibrary.wiley.com/doi/full/10.10…

Landsat nighttime images are useless in visible and infrared bands, but it seems they can tell us stories in thermal bands, waterbodies stay warmer at night when compared to the surroundings. The difference is sometimes >10-15 degrees: code.earthengine.google.com/b8d79aaadd41b8…

New paper out! We study the distribution and spatial arrangement of human settlements in the world. We study an (Open!) dataset of satellite imagery at high resolution (10m!) and find two emerging patterns, namely agglomeration and dispersion. nature.com/articles/s4159…

Study suspects microbial methane emissions are on the rise due to fall of C-13 isotope. Global methane pledge (globalmethanepledge.org) signed at COP26 needs to be rigorously implemented to control anthropogenic methane emissions and thereby any warming induced CH₄ release.
