A Changing Jet Stream

Climate Changes

Climate change appears to be affecting the jet stream, altering the weather patterns over the U.S. so that regions can get “stuck” in extreme weather for weeks, a new study has found. The jet stream is the fast-moving, high-altitude air current that shuttles weather from west to east over North America and Europe. But the pronounced warming of the Arctic—where […]

Ozone Hole Over Antarctica

Ozone Hole Over Antarctica

The ozone layer is a protector of the earth from ultraviolet radiation from the sun.  According to reports the ozone layer is getting smaller over Antarctica.  The scientists are using satellites and sensors to get information on the measurements of the ozone layer. Since the early 20th century when the emissions of chemical substances called halo-carbons the ozone layer has […]

CAN A HURRICANE BE DEACTIVATED?

CAN-A-HURRICANE-BE-DEACTIVATED

We all know that hurricanes are very powerful and destructive.  Some scientists think that we can try to control them by slowing, stopping or weakening them with pumps.  The pumps would bring the colder water to the surface from deep into the ocean waters to decrease the heat that hurricanes thrive on.  This system would be very costly transporting the […]

Climate change helps Alaskan grow organic food on the tundra

Between fighting wildfires and rerouting the Iditarod, Alaska has had a tough time with climate change. But at least there’s one good outcome: local food. In Bethel, a town in southwestern Alaska, farmer Tim Meyers is taking advantage of rising temperatures to grow food in the previously inhospitable tundra. NPR reports: At the 15-acre organic farm, which has been operating for more […]

Heat is heading for new extremes

Heatwaves that used to arrive once every 20 years or so could become annual events by 2075 across almost two-thirds of the planet’s land surface – if humans go on burning ever more fossil fuels and releasing ever more greenhouse gases. Claudia Tebaldi, visiting scientist at the US National Center for Atmospheric Research, and Michael Wehner, senior staff scientist at […]

Oxygen-starved oceans held back life’s recovery after the ‘Great Dying’

Stanford scientists have found that chronically low levels of oxygen throughout the oceans hampered the recovery of life after the Permian-Triassic extinction, the most catastrophic die-off in our planet’s history. Also known as the “Great Dying,” global ecosystems collapsed as some 90 percent of species perished in this extinction event 250 million years ago. The new findings, published this week […]

The Arctic’s ozone hole

The ozone layer over the Arctic Circle developed a giant hole this winter, scientists say. Over the North Pole, 40 percent of the ozone layer has disappeared—a record seasonal loss. Ozone high in the atmosphere shields the Earth from harmful UV rays, and it fluctuates seasonally; usually about 25 percent of the Arctic’s ozone layer fades every winter. In the […]
