Last week, Google, Facebook, and Microsoft were criticized for sponsoring a conference that featured groups that promoted climate change denial. In response, congresswomen Alexandria Ocasio-Cortez and Chellie Pingree co-authored a letter to these Silicon Valley giants, shaming them for supporting the event and giving them a lesson on the dangers of climate denialism.

LibertyCon, an annual student-led event held in Washington, D.C. for young libertarians, featured the CO2 Coalition—a group that asserts CO2 is actually good for the planet, and not a huge, human-accelerated contributor to climate change. When President Donald Trump withdrew from the Paris Climate Treaty, the group wrote in “enthusiastic support” of the decision. Withdrawing from the Paris agreement made the United States one of only three UN member states to not to participate, taking the US out of the global conversation on how to reduce carbon emissions and slow the harm of climate change.
