A catastrophic global wildfire season is underway, while fossil fuel companies announce record profits and push for legislative immunity. Hear more from @ucs.org Policy Director Rachel Cleetus on fires in a changed climate.

The record-shattering, deadly #heat dome followed 3 years of hottest global temps in recorded history thanks to fossil fueled-climate. Heat is deadliest climate impact in the U.S., particularly in cities' due to urban heat island effect. Too often, killer heat flies under the radar. bit.ly/4wcKCmJ

Now more than ever, I will keep pushing to pass my bipartisan Asunción Valdivia Heat Illness, Injury, and Fatality Prevention Act to establish guaranteed workplace heat protections in federal law. These protections will save lives, and I will always stand with our workers.

Hardworking Americans are dying from heat on the job, and Republicans are saying they don’t deserve basic protections to prevent it.

The people who keep our country running, from farmworkers to delivery drivers, often work under extremely hot conditions, risking heat stroke and, too often, their lives. These deaths are preventable with commonsense protections like rest, water, and shade.

But today, House Committee on Education and Workforce Republicans marked up their Heat Workforce Standards Act to prohibit the Secretary of Labor from enforcing a federal workplace heat stress standard. It's cruel and indefensible.

This heat wave brought to you by ExxonMobil and Chevron.

4/ Congress: protect your constituents from extreme heat and other weather hazards made worse by fossil-fueled climate change.

Protect NOAA and FEMA from Trump's Dangerous Budget Cuts

3/ As a record “Super El Niño” gathers strength and the Trump administration continues to attack science-based tools and policy, protecting the public services that keep people safe and aware is crucial.

Danger Season Is Here Again, with Triple the Danger for 2026

Climate change, harmful leadership, and an unaffordable cost of living loom large this Danger Season.

2/ Alongside high electricity costs and demand, triple-digit extreme heat could elevate wildfire and drought risks in the already-dry West and northern plains, threatening the grid and agriculture. Those who need cooling to stay safe may struggle to access - or afford - it.

100 million Americans expected to be under dangerous heat this week

From Los Angeles to Boston -- dangerous heat will impact more than 100 million Americans this week.

1/ Forecasting from NOAA’s critical HeatRisk tool tells us a scorching heat wave is engulfing the western U.S and the upper Midwest. A heat dome has led to multiple new all-time record highs, and more fossil-fuel-driven heat is expected through the end of July.

Are you feeling the heat? 🥵🌡️ Summer's always been hot, but the summer that was is no more. But there are solutions. Read on... 🧵

1/ It’s a dangerous week in climate for Texans and World Cup goers: both extreme precipitation and heat are threatening large areas, including match-hosting Houston and Dallas. Humid, hot conditions are driving up the heat index and “real feel” temps, which could top 115°F in places.

1/1 And this is why we call it “Danger Season”… Extreme weather threatens much of the interior US and Gulf Coast this week. Today’s weather happens in today’s changed climate -- changed mainly through fossil fuel use -- turning summer dangerous. Stay safe out there! (weather.gov)

The Office of Management and Budget proposed restricting what research can be funded and allowing political appointees to block funding that conflicts with presidential priorities. This is “a new kind of institutional vandalism,” according to Dr. Melissa Finucane.

3/ With oceans being pushed into hot, unprecedented territory, we need to defend NOAA, the key fed agency helping us monitor and understand these changes. Tell your members of Congress that science must be a non-negotiable priority:

2/ The combo of fossil fuel-caused climate change and a potential super El Niño event makes a terrible team. Global temps could easily reach record levels this year and/or next. Check out Marc Alessi’s blog post on this:

Terrible Team: Super El Niño and Climate Change Could Lead to Record-Breaking Global Temperatures

The pairing could be bad news for our climate system.

1/ El Niño has officially developed in the eastern Pacific, according to NOAA. Per the Climate Prediction Ctr, there’s a 63% chance of this El Niño becoming very strong, or “super.”

UCS’s Rachel Cleetus joined @eesionline.org’s podcast, The Climate Conversation, to discuss the risks posed by the upcoming summer months of Danger Season and what lawmakers must do to protect us as climate change intensifies. “We shouldn’t wait for a disaster to strike to act." #EarthDay:

Big Oil companies are going all-out to avoid taking responsibility for the harm caused to communities and for driving the climate crisis. They are using an age-old strategy: delay, distort, and deny. But we won’t let them off the hook.

In his blog, UCS’s Julian Reyes explains how Forest Service restructuring is irreversibly damaging the federal scientific enterprise. It leaves the nation facing growing climate threats with fewer experts to manage wildfires just as risks are surging across the US. 🔗 act.ucsusa.org/4sqD11s

DHS Sec Mullin's 1st official trip to check on Hurricane Helene recovery in North Carolina made it clear he’ll continue President Trump's destructive agenda to restructure FEMA including continuing to place the burden of disaster response & recovery onto states and local gov’s. bit.ly/4tuWhvp

Last week’s monthly wildland fire outlook shows that the US wildfire season is already off to an above-normal start. UCS’s Rachel Cleetus breaks down the risks and impacts of climate change-driven heat across the country, pointing to the lack of policy response from the Trump administration.

Here is the March 2026 temperature departure from the 1991-2020 normal. 🔥🔥🔥

Climatologist49@climatologist49.bsky.social · 4mo ago

🚨🚨🚨 March 2026 was the warmest March on record according to Prism climate data (1895-present). Previously, 2012 was far and away the warmest March, but this March beat 2012 by about half a degree Fahrenheit. This map shows how March temperatures ranked compared to all other Marches.🔥🔥🔥

This proposed budget would further enable the Trump administration’s reckless and illegal military actions around the world while directly harming our health and safety. Congress should reject this destructive budget proposal.

The administration is also still trying to throttle clean energy investments, attack life-saving science and gut pollution safeguards which would contribute to higher energy costs, increased pollution and greater risks to people’s lives and health.

The White House has released its 2027 budget proposal – including an astonishing $1.5 trillion in military spending, an unprecedented increase of 66% over the previous year. 🧵

Trump’s Proposed Military Spending Would Be a “Bloody New Deal” 

If passed and sustained, President Trump’s new defense budget could become the largest discretionary spending increase in modern US history.

A critical FEMA tool that helps officials decide when to evacuate communities at risk during hurricanes -HURREVAC- is caught in FEMA’s red tape, once again causing frustration and unnecessary concern at all levels of government. wapo.st/41vGiBf

Hurricane evacuation tool will soon expire due to DHS approval delays

The tool helps determine if and when public safety agencies should evacuate neighborhoods when a hurricane is approaching.
