Un nuevo Atlas Sudamericano de Sequía revela que las sequías severas expandidas y los períodos inusualmente húmedos sin precedentes han ido aumentando desde mediados del siglo XX.
A new South American Drought Atlas reveals that unprecedented widespread, intense droughts and unusually wet periods have been on the rise since the mid-20th century.
A simple fascination with winter and weather patterns led D’Arrigo to become a globe-trotting scientist who collects and analyzes important data from tree rings.
Using old tree rings and archival documents, historians and climate scientists have detailed an extreme cold period in Scotland in the 1690s that caused immense suffering. It may have lessons for Brexit-era politics.
On a peninsula within sight of New York City, researchers are studying trees dating as far back as the early 1800s. Rising seas and more powerful storms, both fueled by climate change, could eventually spell their end.
Centuries-old trees on a peninsula near New York City could provide an important record of past storms. Researchers recently traveled there to sample the trees before they are wiped out by rising seas and powerful storms.
Measurements of stable isotopes in tree rings may expand the climate information that scientists can get from old trees.
Accounting for Volcanoes Using Tools of Economics
Climate scientists teamed up with an econometrics expert to develop an innovative new method for picking out past volcanic eruptions in temperature reconstructions going back millennia and gauging their impact on the climate.
“If climate change is having an impact and is making droughts worse, then we should see this in the record over several centuries—and we do,” said the study’s author, Benjamin Cook.
On every continent and ocean, Earth Institute field researchers are studying the dynamics of climate, geology, natural hazards and ecology, and their practical applications to modern problems. Below, a list of expeditions in rough chronological order. Work in and around New York City and the U.S. Northeast is listed separately toward bottom. Unless otherwise stated, projects originate with… read more
