More subsidies for fossil fuels that we all pay: “securing American industry access to Venezuela’s oil fields, which account for roughly 17% of the world’s known reserves. A sustained U.S. military presence will be required…for the foreseeable future”

We need to speed up tangible climate action: “Climate action has been slow, which means that the world is in for considerable warming, more extreme weather and more harm for people who already do not have the resources to make themselves more resilient”

Sadly true: “The administration would rather pretend: If we don’t see it, study it, or predict it, then it doesn’t exist. The future impacts of tornadoes, hurricanes, wildfires, droughts and other weather disasters on our nation will sadly show them otherwise.”

Science - including world leading atmospheric research - keeps our nation strong, and our citizens safe. Let’s move beyond politicizing it. Let’s move beyond the BS and put our citizens and the health of our nation/planet first. bigpivots.com/was-this-cli...
