The stars over Big Bend belong to all Texans, not the Ultra Wealthy. Now data center development in West Texas is raising new concerns about protecting our dark skies, including those surrounding McDonald Observatory. We need to protect our natural treasures before they’re lost to corporate greed.

Large white text reads, “Data center threatens Big Bend dark sky near McDonald Observatory.” The graphic includes Clayton Tucker’s campaign branding and @ClaytonTuckerTX.

Not all online hate for climate communicators comes from people who reject the science.⁣ ⁣ Some comes from people who believe it, and have quietly given up. Saying something can still be done threatens the only comfort they have left.⁣ ⁣ Hope is the harder message here.⁣ ⁣ @katharinehayhoe.com

BREAKING📢 Crack team of climate scientists show "it is no longer defensible for companies proposing new or extended fossil fuel projects to claim the climate harms will be negligible. Our research shows the harms are, in fact, tangible and quantifiable – and no project is too small to matter"
theconversation.com
For the first time, we linked a new fossil fuel project to hundreds of deaths. Here’s the impact of Woodside’s Scarborough gas project
The results challenge claims that the climate risks posed by an individual fossil fuel project are negligible or cannot be quantified.
