A warmer world will be a hazier one

Aerosols, tiny solid and liquid particles suspended in the atmosphere, impact the environment by affecting air quality and alter the Earth’s radiative balance by either scattering or absorbing sunlight to varying degrees. What impact does climate change, induced by greenhouse gases (GHGs), have on the aerosol “burden”–the total mass of aerosols in a vertical column of air? Past research done […]

Antarctica’s Balmy Past

When the atmosphere had much higher levels of carbon dioxide, Antarctica was as warm as California. New research has revealed that 430 million to 50 million years ago, temperatures on the frozen continent averaged 57 degrees Fahrenheit, with part of the surrounding Pacific Ocean reaching up to 72 degrees. In this ancient era, known as the Eocene epoch, carbon dioxide […]

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 […]
