PRESERVE THE PAST • PROTECT THE FUTURE

Save America's Most Important Climate and Weather Record

For more than 141 years, Blue Hill Observatory has preserved one of the world's longest, most complete, and most scientifically valuable continuous weather records. Today, funding cuts threaten the observations that scientists rely on and the historic archives that remain undigitized. Help protect this irreplaceable record before it is lost.

The Last Best Independent Climate Record

As federal science funding erodes, Blue Hill Observatory stands at a crossroads. We hold North America's longest continuous weather record — data that NOAA, NASA, and leading universities rely on. That record doesn't maintain itself.
