Probably the most accessible overview of the latest climate science evidence and projected changes is published today - one to send to your families/friends/kids who are interested @IPCC_CH https://t.co/hzyyagTEOp

@C_Derksen @envwaterloo @ECCCSciTech Congrats Chris! You never leave the @GeogWaterloo family 👏

I'm excited to be part of the @csa_asc -supported consortium developing new satellite instruments to help tackle climate change. @UWResearch @climatechangeUW

[University of Waterloo @UWaterloo]

The High-altitude Aerosols, Water Vapour and Clouds (HAWC) mission received $200 million and #UWaterloo is among the top institutions that will participate to improve our understanding of global climate change.

My role will be improving how we measure precipitation (mainly snow) in high latitudes, and using that information to improve computer models that predict future climate change.

[Chris Fletcher @ClimoChris]

@BokhariSpace @UWaterloo @envwaterloo @csa_asc @SpireGlobal @exactEarth The Canadian space industry has a great history of partnerships with @csa_asc and will be key to building the HAWC instruments.

[Chris Fletcher @ClimoChris]

Very big day for climate and atmospheric science in Canada. CSA investing $200m+ in next-gen Earth observation to improve understanding of climate change. Proud that @UWaterloo is partner in coast-to-coast science consortium. 🚀🛰️🌧️👏 https://t.co/QVrkC37zkV

[University of Waterloo @UWaterloo]

.@UWaterloo is proud to be a part of this majour multi-satellite mission that will improve extreme weather prediction, climate modelling, and the monitoring of disasters.

Excellent #AcademicTwitter discussion, with many useful references, on the perils of relying on precipitation from reanalysis systems (yes, even ERA5... 😲). Good to see CloudSat continuing to prove its worth. 🛰️🌧️

This is the content we need today. I can't stop watching this drama.

[Mike Galsworthy @mikegalsworthy]

C’mon little guy - you can do it!! https://t.co/YOp5ZJL1qC

[Chris Fletcher @ClimoChris]

Maybe I'll record a reaction video when I show my climate modelling class the source code for @NCAR_CGD's CESM next week... 😲

[David Ho @_david_ho_]

I think people would be shocked to learn how much important climate science is done in Fortran.

[Michael White @MWClimateSci]

Stunningly awesome that climate scientists Syukuro Manabe and Klaus Hasselmann are sharing in this year's Nobel Prize in Physics! Here's a @NaturePortfolio collection of work published and inspired by the winners. https://t.co/0npquCmhFN

[Glen Peters @Peters_Glen]

Did you know, that if CO₂ emissions go to zero, the atmospheric CO₂ concentration will decline, perhaps 100ppm over 100 years.

That is since land & ocean sinks continue to take up carbon until equilibrium is reached.

But...

This wonderful video is exactly the content I needed today. Brilliant.

The beauty, complexity and ferocity of nature. Stunning video.

[Tim Bartholomaus @TimBartholomaus]

The extent of the crevassing at #TurnerGlacier is like nothing I've ever seen before. I actually found the sense of violence experienced by this tortured ice viscerally affecting. I'm relieved to have my feet back on the ground.

[Ed Hawkins @ed_hawkins]

It's #WorldOceanDay!

Note the singular 'ocean' as there is only one interconnected global ocean.

Animated version of Gulf Stream sea surface temperatures done with @oceanographer from yesterday - inspired by the moving media #art installations @refikanadol ! Shading and texture comes from simulated zonal currents #SciArt @neuro_rish @matplotlib #FESOM2

[Chris Fletcher @ClimoChris]

Interesting perspective as IPCC AR6 wraps: current climate science to reduce uncertainty in climate sensitivity ignores political realities and likely won't affect mitigation policy.

Impressively-quick turnaround on the CovidMIP results. Impacts of lockdowns mostly as expected: CO2 and aerosols⏬, locally more☀️in polluted regions, not enough to affect climate.

Air quality/health impacts may be more interesting?

[Prof. Tatiana Ilyina @ilitat]

Did the Drop in COVID-Related Emissions Affect the Climate? - Results of the COVID-MIP now highlighted in EOS.
Global emissions dropped markedly in 2020, due in large part to lockdowns, but the climate likely won’t be noticeably affected. https://t.co/2gKxzh9tF5

It's May the 4th, and the email reminder says the due date for my son's book bundle just *happens* to be today. Well played @WaterlooLibrary, I see the Force is strong with you! 👏
