This year I attended my first COP as your Minister of Environment and Climate Change. Amid the ups and downs of summit diplomacy, one thing stood out that I wasn’t fully prepared for in Glasgow. Read my take on #COP26 here: nationalobserver.com/2021/11/20/new…

[1/2] Wondering what the findings from IPCC’s #ClimateReport mean for Canada? Advancing our understanding of #ClimateChange requires collaboration with scientific experts from around the world and here at home. 🗺️ 🇨🇦

The IPCC Working Group I AR6 Summary for Policymakers was approved in the summer of 2021. What do the key findings mean for Canada? An overview is provided in a new supplement to Canada’s Changing Climate Report available here: changingclimate.ca/CCCR2019/

The #IPCC #ClimateReport has just been approved!! 🙌 16 days, capped off with a final ~40hrs straight of line-by-line negotiation & approval. As one of the authors of the report, this moment culminates years of work. Congratulations to all the authors, Chairs and delegates 🎉

**The IPCC AR6 scenario database** Edward Byers (basically the chef of the database!) just released the AR6 Scenarios Explorer hosted by IIASA Explore and download the scenarios underpinning the AR6 WGIII report on Climate Change Mitigation: data.ene.iiasa.ac.at/ar6/#/about

You can always count on Carbon Brief to present a nice and clear summary. Here IPCC AR6 WG3 (mitigation of climate change) approved last night. 👇

Why is yet another UN climate report being released today, you ask? This is part three of the three-part assessment. The authors' work is staggered in purpose, so each part builds on the previous part(s). In September, a synthesis of all three will be released. (1/2)

We are live! IPCC #ClimateReport: the physical science basis ipcc.ch/report/ar6/wg1/ Find the final chapters, figures, many resources and more. Soon to come.. the full report in html. Special thanks Tom Maycock Jussi Savolainen Elle Leitzke Diego Cammarano Clotilde Péan 👏👏👏

Why does increasing atmospheric CO₂ warm the planet? The greenhouse effect, duh. But do you know how that works? I can *almost* guarantee you that you don’t quite have the right picture in mind—in a way that actually matters. Interested? Here’s a new physics thread! 1/29

Analysis: How well have climate models projected global warming? | Zeke Hausfather #archive Read here: bit.ly/2VxSeR2

Our scientists contributed to the American Meteorological Society, State of the Climate Report. One key finding: Canada was on average 1.0oC warmer in 2021 compared to the last 30 years. Read the report: ametsoc.org/index.cfm/ams/…

For those who don’t want to ignore the science or ignore the data.

1822: Joseph Fourier suggested the atmosphere’s role in retaining heat was like a greenhouse 1859: Eunice Foote suggested CO₂ was the main greenhouse gas 1861: John Tyndall performed detailed experiments that identified all the major greenhouse gases

Under none of the 82 scenarios Canadian Climate Institute ran is Canada a climate change winner. The impacts of climate change are deepening, driving widespread cost mounting in time. Reducing global emissions and adapting will avoid the worst costs yet to come. climateinstitute.ca/reports/damage…

@seis_matters Climate models have been shown to make pretty accurate long-term predictions, see for example carbonbrief.org/guest-post-the…

In case you don’t believe the same equations govern motion in the atmosphere and the ocean.
