This morning (Korean time), @IPCC_CH’s Special Report on keeping global warming below 1.5°C was published. You find its Headline Statements here:…

Thread: “Global warming is likely to reach 1.5°C between 2030 and 2052 if it continues to increase at the current rate.”
That’s what would probably happen if we keep global emissions flat. It already gives a sense of how fast we should reduce emissons to stay below 1.5°C.

In discussions on the climate ‘hothouse’ paper, it’s interesting to see how annoyed some people get by the word stewardship. It’s labeled as anti-conservative, socialist, etc. To me, stewardship is a positive word, and I remember it was e.g. often used by christian-democrats in this country. Checking it in the dictionary, I found this. Seems rather appropriate, given the climate crisis we’re causing.

“What if we started economics not with its long-established theories, but with humanity’s long-term goals, and then sought out the economic thinking that would enable us to achieve them?”
The central question in @KateRaworth’s Doughnut Economics. @KateRaworth Today, we have economies that need to grow, whether or not they make us thrive: what we need are economies that make us thrive, whether or not they grow.

By end-2017, renewables produced 26.5% of the world's electricity, up from 24.5% one year before! Fast growers: wind (4.0 → 5.6%) and solar PV (1.5 → 1.9%).
@ren21's new report: Share of wind+solar PV in total 2017 electricity generation highest in Denmark (57%), followed by Uruguay (30%), and 4 European countries above 20%: Germany, Ireland, Portugal, and Spain.

Confirmed: Atmospheric CO2 measured at Mauna Loa averaged 410.3 ppm in April. First time a monthly mean exceeded 410 ppm, just four years after the 400 ppm line was crossed. Since I was born, CO2 at Mauna Loa crossed:
320 ppm in May 1960
330 in May 1972
340 March 1980
350 May 1986
360 May 1993
370 April 1999
380 April 2004
390 May 2009
400 April 2014
and 410 ppm in April 2018
I apologize for any inconvenience caused.
