I think climate change needs to be noticed more by political leaders, as much as COVID is. Our world is dying and we are not doing anything about it. Climate change has been an ongoing issue, and soon damage will be irreversable.
2016-2020 were amongst the hottest years and studies say that by 2030 the world would need to cut the emissions of the top carbon polluting countries to have a chance at staying below the 1.5C.
I think we need to focus a lot on climate change due to the rapid melting in the Arctics, and our soon irreversable damage to our world, plants and animals.
