New Report Predicts Possible Dip in Global CO2 Emissions

December 7, 2015

An international collaboration of scientists, in a new report, predicts the percentage of global carbon dioxide emissions from fossil fuels may actually dip slightly in 2015 compared to 2014 levels. “In 2014, global CO2 emissions from burning fossil fuels grew by just 0.6 percent,” said the report’s lead author Rob Jackson, a professor of Earth […]

New Sunspot Index Breaks Link Between Solar Activity and Climate Change

August 11, 2015

A newly updated analysis of sunspot numbers over the last 400 years suggests solar activity has nothing to do with climate change, a discovery that eliminates a key argument used by those who question human caused climate change. Some of those who suggest that climate change is not anthropogenic in nature contend that changes in the […]

Astronomers Spot Square-shaped Hole in Sun

May 19, 2014

NASA astronomers recently noticed an odd looking, square shaped hole in the sun. What they saw is called a coronal hole, something that occurs on a regular basis. Dean Pesnell, project scientist for the Solar Dynamics Observatory at NASA’s Goddard Space Flight Center in Maryland, says the coronal hole is an area within the corona […]

Scientists See Processes Behind Major Solar Events

July 16, 2013

Over the past several years, NASA spacecraft studying the sun have sent back some spectacular images of it exploding with solar flares and coronal mass ejections.  Now, scientists say that two of these spacecraft — the Solar Dynamics Observatory (SDO) and the Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI) — have detected a phenomenon […]
