    I started a new list that has nothing to do with anything that is wrong with our world and everything to do with what is good. It is called "scientists who craft" ... as in, get creative w knitting, woodwork, quilting, and more. LMK if you should be on it!

    This is good. An insurance firm in the UK has made free counselling services a standard part of its flood policies due to the clear impacts of climate-linked disasters on mental health. A model that will spread?

    Prof. Hayhoe has summed up in a few tweets what whole books have struggled to explain about climate goals and temperature thresholds. A good and worthy read @ the pros and cons of temperature targets.

    When it comes to what climate goals we should be aiming for, there are a lot of "magic numbers" floating around - 2 degrees, 12 years, 350ppm, net zero emissions, and more. Here's a short thread explaining the scientific basis--or lack thereof--for each.

    "It's no longer a question of when the impacts of climate change will manifest themselves: They are already here and now. The only question remaining is how much worse it will get. The answer is up to us." -- Climate scientist Katharine Hayhoe

    Now that U.S. climate change policy is back in the news, this thread serves as a great primer for those looking to get caught up on climate-related buzzwords and targets. tl;dr less fossilized carbon into the atmosphere -> less T increases -> less environmental impacts

    Wow, this is huge -- it opens up exciting new questions about how local populations respond to climate or other environmental changes over thousands of years -- did they adapt? In what ways? How quickly?
