CLIMATE SCIENCE, MADE ACCESSIBLE
Understand our planet. Explore what matters.
A clearer window into our changing world. Explore historical weather, compare published sea-level scenarios and check model-based air-quality forecasts—all with transparent sources.
Free to explore. No account. No API key required.
THE BIGGER PICTURE
Explore the science. See the context.
Each tool separates observations, modeled estimates, and published projections so the numbers mean what they say.
Climate explorer
Compare modeled historical temperatures and precipitation for a location, year by year.
Explore location 02 / PROJECTIONSSea-level scenarios
Understand the published IPCC AR6 likely ranges under very low and very high emissions.
Compare scenarios 03 / MODEL FORECASTAir quality outlook
Check a modeled AQI estimate for a U.S. city or ZIP code—not an official station reading.
Check local air01 / HISTORICAL DATA EXPLORER
Discover the patterns behind the weather.
Explore yearly averages from ERA5 historical weather reanalysis. These location-specific, modeled estimates are not direct thermometer records or global climate trends.

Source: Open-Meteo Historical Weather API, using ERA5 reanalysis; values are aggregated from daily estimates. Open-Meteo data: CC BY 4.0. Results depend on model coverage and availability.
02 / THE OCEAN OUTLOOK
A rising ocean. Different futures.
Published global mean sea-level rise ranges from the IPCC Sixth Assessment Report. These are projections, not measurements or personalized flood-risk predictions.
Compare likely ranges
Projected change relative to the 1995–2014 global mean sea-level baseline
Ranges are IPCC AR6 likely global projections, not a forecast of local flooding. Values shown for 2050 and 2100 only; no invented intermediate-year interpolation. Read the IPCC source.
03 / THE AIR AROUND YOU
Know what's in the air. With context.
Get a model-based air quality forecast for a U.S. city or ZIP code. For official local monitoring, check AirNow.gov.

Transparency is part of the experience.
This independent educational project separates historical modeled weather, future scenario projections and modeled air-quality forecasts. It does not show certified monitoring-station data, provide medical advice or predict local flood damage.
Built with HTML, CSS and JavaScript on GitHub Pages. Free API responses may be rate-limited or temporarily unavailable. If a request fails, the app explains the limitation instead of inventing a value.
Frequently asked questions
Are these climate measurements live?
No. The historical explorer shows ERA5 weather reanalysis, the sea-level section shows published IPCC projections, and the air-quality section shows modeled near-term forecasts. Each uses its own time scale and source.
Can I use this to assess flooding at my address?
No. Global mean sea-level rise is not the same as local coastal flood risk. Local elevation, land motion, tides and storm surge require specialist data.
Why isn't there a live climate news ticker?
The earlier free news API stopped working. Rather than display unverified or out-of-date headlines, this site links directly to NASA, NOAA and IPCC sources.
Does this site ask for my location?
No automatic geolocation permission is requested. You enter a city or ZIP code, and the location is sent to public geocoding and weather or air-quality data providers to retrieve results.
