Rising thunderstorm clouds increase warming

As a regular you will be well aware that some clouds cool the climate and other clouds warm. Determining the exact balance of the cloud-climate feedback will help decrease uncertainty margins for 21st century warming forecasts. Unfortunately it’s a complicated … Continue reading

Natural sulfur aerosol emissions provide support for Gaia hypothesis

Is Earth really a sort of giant living organism as the Gaia hypothesis predicts? A new discovery made at the University of Maryland may provide a key to answering this question. This key of sulfur could allow scientists to unlock heretofore hidden interactions between ocean organisms, atmosphere, and land — interactions that might provide evidence supporting this famous theory.

Mid-Atlantic suburbs can expect an early spring thanks to the heat of the big city

Urban heat island around Washington and Baltimore would lead to longer growing season, warmer autumn and spring

If you’ve been thinking our world is more green than frozen these days, you’re right. A recent study has found that spring is indeed arriving earlier – and autumn later – in the suburbs of Baltimore and Washington, D.C. The reason? The urban landscape traps heat in the summer and holds it throughout the winter, triggering leaves to turn green earlier in the spring and to stay green later into autumn. The result is a new, extended growing season.
