Global warming is real, but I wish we paid more attention to biodiversity and set goals there instead of fixating on temperature. I understand why temperature is there. It is easy to measure and an easy number to campaign around, but biodiversity, to me, is the actual point and focusing on temperature, while a major factor, diminishes the many other issues attacking it.
So we have already surpassed 1.5C by this measure, and will pass 2C earlier than predicted. Does that mean the various events predicted to occur around 2C will also occur earlier? Or not, because this paper measures from an early date?
Montreal is particularly warm but dry this winter -- actually in many days warmer than Shanghai, China. I hope we don't have a super cold March this year.
Meh, don't care.<p>Seriously, we had ice ages. Temperatures go up and down.<p>I can't bring myself to care about 86 instead of 83 degrees F in the summer and 23 instead of 20 in the winter. It's like moving a few hundred miles south. People get by fine.<p>I mean, I'm worried about all the weird chemicals in my food. That seems kinda wacky. I'm worried about all the biodiversity disappearing. Extreme-weather-itis would be scary, if it's actually a thing. I'm worried about breathing more CO2, and especially about the same in water (ocean acidification). I'm worried about many of the other impacts on climate.<p>"Climate change" was a step forward in terminology from "global warming," but we need about five more steps before it's something people care about.<p>We also need to acknowledge how much we don't know. Most of our models from 20 years ago didn't play out, which was obvious if you read the papers instead of listening to Al Gore. Bad things happened, but not the ones we thought would happen. It's a chaotic system. It doesn't work predictably.
What about this hockey-stick shaped curve ?<p><a href="https://revistapesquisa.fapesp.br/wp-content/uploads/2019/07/012-017_Notas_277-info.jpg" rel="nofollow">https://revistapesquisa.fapesp.br/wp-content/uploads/2019/07...</a>
