Some flyers buy 'carbon offsets' to atone for airline climate sins. But does that do any good?
Having grown up with parents who encouraged recycling, Jenny Beightol has always been aware of her environmental impact. She doesn’t own a car, and bikes or takes public transportation to get around town.But the 32-year-old Chicagoan sometimes likes to travel to places like Mexico. This has led to soul searching, because scientists say that planes account for about 2.5% of global carbon dioxide production, which contributes to climate change.To ease her guilt, Beightol buys “carbon offsets,” which allow her to invest in environmental projects as a way of compensating for the greenhouse gas emi...
'Invisible oil' from Deepwater Horizon spill may have reached the Florida Keys
MIAMI — Florida Keys residents may not have seen massive tar balls and fish kills after the 2010 Deepwater Horizon oil spill, but small concentrations of toxic crude were still reaching the islands and potentially harming marine life, as the extent of the deadly disaster in the Gulf of Mexico was worse than originally thought, according to a University of Miami study.Nearly a decade after the worst offshore oil spill in U.S. history killed 11 people and dumped 200 million gallons of crude into the ocean, researchers found discrepancies in the satellite footprint that was used to establish fish...
A spacecraft launching Sunday will take the first-ever images of the Sun's poles
ORLANDO, Fla. — On Sunday night, a $1.5 billion spacecraft is scheduled take off from the Space Coast on a years-long journey that, if successful, will take the first-ever images of the Sun’s poles.It’s data that scientists have been yearning to obtain for years, and it may answer crucial questions about the nature of our Sun and, chiefly, the charged solar particles it spews and their impact across the solar system. The mission will send the European Space Agency’s Solar Orbiter on a seven-year journey and help heliophysicists gain a better understanding of the dark spots believed to be on th...
Hurricane experts should look to the water, not the wind for accurate predictions, new study says
ORLANDO, Fla. — The answer to a hurricane’s power isn’t in the wind.It lies in the water.A new study indicates that meteorologists should shift their attention from a hurricane’s maximum sustained wind to the “minimum sea level pressure” when calculating risk for residents during hurricane season, according to the Department of Atmospheric Science at Colorado State University.MSLP is a more useful metric in determining the size of a hurricane, the strength of a storm surge, rainfall footprint and number of fatalities.The study reexamined Atlantic storms that made landfall in America from 1900 ...
You've likely never heard of the world's greatest ocean migration. Satellite data is helping scientists study it
The greatest animal migration on Earth is likely something you never heard of and few have witnessed: legions of tiny marine creatures rising to the ocean surface every night to feed on tiny plants, then sinking back into the deep, dark water at dawn.Called the diel vertical migration, it was first recorded nearly 200 years ago by hauling ship nets through the water column. Today, marine scientists still sample the movement using shipboard nets. They also shoot acoustic signals into the water to track the sound “backscattering” off the zooplankton as they migrate up and down. Some collect data...
