'Warming hole' delayed climate change over eastern United States

Cambridge, Mass. - April 26, 2012 - Climate scientists at the Harvard School of Engineering and Applied Sciences (SEAS) have discovered that particulate pollution in the late 20th century created a "warming hole" over the eastern United States—that is, a cold patch where the effects of global warming were temporarily obscured. While greenhouse gases like carbon dioxide and methane warm the Earth's surface, tiny particles in the air can have the reverse effect on regional scales.

Scientists have discovered that climate change played a major role in causing mass extinction of mammals in the late quaternary era, 50,000 years ago. Their study takes a new approach to this hotly debated topic by using global data... Read Post

Particulate Pollution Combined With Airborne Soot Adds To Global Warming

Academics / General Science : Science Daily (5 years ago)

Particulate pollution thought to be holding climate change in check by reflecting sunlight instead enhances warming when combined with airborne soot. An instrument that measures the chemical composition and optical properties of aer... Read Post
