Arrhenius' descendant, Greta Thunberg, is leading a worldwide effort to keep global warming under 1.5 degrees. She has been nominated for the Nobel Peace Prize as well. Maybe there will be 2 Nobels in the family.

>1.5 degrees

I was under the impression that there was worldwide consensus that we will pass 1.5 -- that it's too late to realistically prevent that. More, that if you count from the late 19th and early 20th century averages we've already passed 1.5.

The number isn't that relevant, whether its 1.5 or 2C. What is relevant, that we can limit the temperature raise only if we strongly stop on the breaks with respect to CO2 emissions. If we don't do that, we will have quite different and much more unpleaseant numbers.

From what I've read, stomping on the breaks with respect to CO2 emissions would very quickly, and very dramatically increase global average temperature due to reduced aerosol masking.

Even if this was the case, and even if there was no realistic workaround to it (the article you linked mentions aerosol emission mitigation), this will happen at some point. Would you rather this happens now, or when the world has warmed 5 degrees already?

a recent paper disputes this: https://www.nature.com/articles/s41586-019-1554-z explanation on Ars: https://arstechnica.com/science/2019/09/we-can-phase-out-fos...

I wonder if anyone's estimated the relationship between global change in temperature and change in QUALYs.

Yes please continue to give the Nobel Peace Prize to people who have actually accomplished nothing. It will surely keep the stature of said award high.

Follow the Fridays for Future climate strikes around the world today(9/20 - already starting in Australia and New Zealand) and see what she has accomplished.

Walk with me here: What has she really accomplished? Yelling at adults that they are bad for not being pre-occupied with something that they individually have zero control over?

This girl is a show-puppy for the media points. It annoys me.

Is she really related to him ? Her dad shares the same first name, Svante, but the connection to Arrhenius I've only found mentioned on troll sites.

[EDIT] I stand corrected. There is afamily link.

The Nobel Peace prize is a joke. Obama won it despite green-lighting the Afghanistan surge.

He won it BEFORE green lighting the Afghanistan surge.

Good point - the committee must be horrible at judging people. Obama had essentially no foreign policy accomplishments at the time that they awarded him, suggesting they gave it out simply as tacit disapproval of Bush.

If the entire prize is a joke, it'd make sense if you could point to patterns rather than one anomaly.

Even more recently it’s likely that Aung San Suu Kyi will be held accountable for crimes against humanity.
