Mount Washington's weather is starting to significantly shift because of climate change. A recent study found its summit and that of nearby mountain pass Pinkham Notch are warming. The findings could have significant repercussions for local ecosystems.
Mount Washington in New Hampshire is famous for some of the world's worst weather.gust ever recorded by a human — 231 mph on April 12, 1934. At 6,288 feet, the weather is often freezing, even in spring. And the weather can change suddenly, catching many hikers off guard.
Today, Fitzgerald oversees a team of scientists who record the weather hourly, calculate forecasts and conduct their own research projects. Despite the excitement, it's a difficult job. Bellefontaine and the other observers live at the summit in weeklong shifts, from Wednesday to Wednesday. Sometimes, that shift gets even longer, if the weather makes visibility at the summit so poor the snowcat they use for transit cannot safely make it up for the shift change.
On the roof of the observatory, weather observer Jackie Bellefontaine spins a sling psychrometer to measure relative humidity. who led the analysis."The people that started observing this were just interested in mountain weather, and didn't realize this old data would eventually become a climate dataset."
