Climate Central: A Science & News Organization

Western Fire Weather Days Increasing

New Climate Central analysis shows more frequent fire weather conditions across much of the western U.S. since 1973. Fire weather days have increased in all four seasons—especially spring and summer.

Peak CO2 & Heat-trapping Emissions

Heat-trapping emissions have continued to increase—and atmospheric CO2 is on track to reach record-high concentrations this month.

Earth Day

Ahead of Earth Day, we’re taking stock of widespread warming in 246 U.S. locations, 49 states, and the nation since 1970.

Our Programs

Collapse

Program on Sea Level Rise

Search by city, state or zip code to track the risk of flooding in your area.

Climate Matters

Climate Matters provides meteorologists with data & graphics on local weather events and their link to climate change.

Partnership Journalism

Guided by data and science, our journalists collaborate with local newsrooms on compelling climate change coverage.

Climate Matters Highlights

Shrinking Cold Snaps

From 1970 to 2021, the longest winter cold snaps shrunk for 97% of the 244 U.S. locations analyzed—a winter trend that can have year-round impacts.

2021 Winter Package

Climate Central breaks down four key concepts to highlight when discussing climate change and the winter season.

The time between billion-dollar disasters—time to help communities across the nation recover—has dropped to just 18 days on average in recent years (2016-2020), according to Climate Central’s new presentation of NOAA/NCEI data.

Climate change and health

Climate Central’s new toolkit shows how climate change is impacting health locally, and how that may change in the future.

New Toolkit

Climate Change and Human Health

Resources on multiple health impacts of climate change, including locality-specific data and background information.

Special Sections & Tools

CoastalDEM® Coastal Risk Screening Tool

Improved elevation data indicate far greater global threats from sea level rise and coastal flooding than previously understood.

WeatherPower

Use WeatherPower to bring wind and solar electricity generation into your forecasts, based on your local installed renewables capacity.

Realtime Climate

Realtime Climate monitors local weather and events across the U.S. and generates alerts when certain conditions are met or expected. These alerts provide links to science-based analyses and visualizations—including locality-specific, high-quality graphics—that can help explain events in the context of climate change.
