Researchers have calculated that human bodies collectively release over 2 billion metric tons of carbon dioxide each year simply by converting food into energy. That figure marks a 74% increase over the past 30 years, driven mainly by population growth. Unlike the CO2 from burning fossil fuels, the carbon dioxide we exhale is part of Earth's natural carbon cycle. Scientists suggest that more…
A team led by University of Massachusetts Amherst researchers has found that weaker rock in mountain landscapes erodes at a rate three times higher than harder rock, even on slopes that are not steep. The study identifies rock strength as a primary factor in mountain erosion, challenging existing models that link erosion to carbon dioxide release. The scientists suggest that current estimates of C…
El Nino, the natural climate pattern that warms equatorial Pacific waters every two to seven years, is currently rivaling the 1997-98 and 2015-16 events. Those past El Ninos caused global upheaval, from Indonesian and Amazon fires to drought-driven crop failures in southern Africa and coastal flooding in Southern California. The present El Nino is rivaling those past heavyweights in strength.
