The main challenge our world is facing today is climate change. You can read more about it in ``The Climate Emergency: 2020 in Review''.
I just signed the ``Global Scientists Call for Economic Stimulus to Address Climate Adaptation and Covid''. If you are a scientist you can support this initiative by signing the paper ``here''. This statement will be released ahead of the ``Climate Adaptation Summit'', hosted by the Netherlands on 25th January 2021.
I also signed the climate emergency initiative ``World Scientists' Warning of a Climate Emergency''. If you are a scientist you can support this initiative by signing the paper (scroll down the page to near the bottom of the page).
