Today is #WorldOceanDay! Who doesn’t love the ocean? But does the ocean love us back? Read on…
Canadian wildfires. Compromised air quality in the Midwest. A prolonged heat wave. The TX derecho and the power outages that came with it... "It's #DangerSeason2024, and everyone needs to be ready. Because the hits are coming, and they’re going to hurt." act.ucsusa.org/4dR0JOf
Today President Biden launched the American Climate Corps to train young adults & provide good paying jobs in clean energy, conservation and climate resilience sectors – Thanks @POTUS, let's do this! @UCSUSA bit.ly/452DfQm
Indeed, X marks the spot. Disinformation is rampant and not properly addressed. And hate? Sad state of affairs. blog.ucsusa.org/kate-cell/for-…
Recent flash flooding in Leominster, MA, swamped cars, homes, and some businesses. With more rain in the forecast for today, here's what you need to know about #FlashFlooding and how to stay safe, according to UCS's Kristina Dahl. —Via @BostonGlobe. bostonglobe.com/2023/09/12/met…
We are honored to see Kristina Dahl, UCS Principal Climate Scientist, recognized in the 2023 #TIME100NEXT list. Her profile on @TIME says she is “one of the great geographers of our disorienting new world.” Congratulations! ➡️time.com/collection/tim…
She's an alchemist of ideas, science & heart, a ground-breaking scientist, a treasured colleague, and simply one of the finest people I know. Congratulations Kristina Dahl!!! With a soft voice and a steel will, you're changing the world for good. @UCSUSA time.com/collection/tim…
July 2023 was Earth's hottest month on record. New analysis from @ClimateCentral shows that human-caused climate change made this summer's unprecedented heat far more likely: climatecentral.org/climate-matter…
(1) We @UCSUSA thank you @POTUS 4 action today on climate-driven #killerheat & #DangerSeason & issuing Hazard Alert for heat & more enforcement to protect workers from extreme heat. bit.ly/44JXX8p
🔥Canada faces an alarming convergence of record-breaking #heatwaves and rampant #wildfires, painting a stark picture of the #climatecrisis. UCS' own @kristydahl discusses the sobering reality in @CatClifford latest article: cnbc.com/2023/07/13/can…
David Watkins, Director of Governmental Affairs at UCS, breaks down the devastating consequences that default would have for our economy, low-income and working families, and the environment. #DefaultOnAmerica
Congress must raise the #DebtCeiling ASAP to avoid harming the economy, with especially damaging consequences for low-income families. Tell Congress to pass a clean debt ceiling bill @SenSchumer @RepJeffries @SpeakerMcCarthy @LeaderMcConnell
New report from UCS directly links coal, oil, and gas companies with worsening forest fires across the western US. Communities of color & low-income communities are paying the heaviest price. youtube.com/watch?v=HlgWBt… bit.ly/3pEIZ46
Today at 10 AM Eastern US: House hearing on “Establishing an Independent NOAA.” Rachel Licker investigates possible implications. Congress Needs to Carefully Chart NOAA's Path Forward blog.ucsusa.org/rachel-licker/… via @UCSUSA
Dear Journalists covering tomorrow's IPCC report release, First of all, THANK YOU. Second of all, here are a couple of questions you should not be asking climate scientists, ever ever ever.
The latest @IPCC_CH synthesis report highlights the realities of the climate crisis today, the dangers of global warming exceeding 1.5 degrees Celsius above pre-industrial levels, and the solutions available to limit climate change and its harms. ➡️act.ucsusa.org/40kDzYZ
An unrelenting, record-setting heatwave has enveloped parts of South America for much of the last few months. Like summer in the US, climate change has turned summer in South America into a danger season with frightening consequences: blog.ucsusa.org/rachel-licker/…
.@erikasiegfried explains the moral dilemma of the well-behaved scientist and asks, "If the reward is breaking society out of our collective trance and into a state of transformative action, what professional—and even personal—risk wouldn’t be worth it?" bit.ly/3R1MMSv
