Chuck Bednar for redOrbit.com - Your Universe Online Propelled by the largest single-year increase in carbon dioxide in three decades, the amount of greenhouse gases in the atmosphere reached record highs in 2013, the World Meteorological Organization (WMO) reported on Tuesday. According to the agency’s annual Greenhouse Gas Bulletin, there was a 34 percent increase in radiative forcing (the warming effect on our climate) due to CO2, methane and nitrous oxide. The report found that...

Foraminifera Fossils Reveal An Ice-Free Late Cretaceous Period

April Flowers for redOrbit.com - Your Universe Online Scientists have long believed that a continental ice sheet formed more than 90 million years ago during the Late Cretaceous Period. During that time, the climate was much warmer than it is today. A new study from the University of Missouri (MU) has found evidence suggesting that this belief is incorrect, that no ice sheet formed during this time. The findings of this study, published in the journal Geology, could help environmentalists...

Brett Smith for RedOrbit.com New evidence points to troubling levels of carbon dioxide, the world´s primary greenhouse gas, in the Earth´s atmosphere. Several arctic monitoring stations are measuring more than 400 parts per million (ppm) of the heat-trapping gas in the atmosphere this spring, compared with the 350 ppm that many scientists say is the highest safe level for carbon dioxide. While some carbon dioxide production is natural, from decomposing dead plants and...

Meteorologists have determined exactly how much carbon dioxide humans can emit into the atmosphere while ensuring that the earth does not heat up by more than two degrees The Intergovernmental Panel on Climate Change (IPCC) calculated projected temperature changes for various scenarios in 2007 and researchers at the Max Planck Institute for Meteorology in Hamburg have now gone one step further: they have developed a new model that specifies the maximum volumes of carbon dioxide that humans...

WASHINGTON, Dec. 10 /PRNewswire-USNewswire/ -- As President Obama prepares to travel to the United Nations Climate Change Conference in Copenhagen, 14 members of the U.S. House of Representatives have sent a letter urging the President to seek agreement with world leaders on the need to reduce the level of carbon dioxide in the atmosphere to 350 parts per million. Climate scientists, led by Dr. James Hansen of NASA's Goddard Space Institute, warn that global temperatures will rise to...

Britain's former chief scientific adviser, David King, said Wednesday that wealthy nations must  reduce greenhouse gas emissions to the current levels of India by 2050 to avoid catastrophic climate change. Carbon dioxide levels across the world are already rising rapidly, and rich nations must quickly determine how to cut emissions while maintaining economic growth, according to a Reuters report quoting King.  "If you (don't want) run-away climate change, you need to be at about...

Now that scientists have reached a consensus that carbon dioxide emissions from human activities are the major cause of global warming, the next question is: How can we stop it" Can we just cut back on carbon, or do we need to go cold turkey" According to a new study by scientists at the Carnegie Institution, halfway measures won't do the job. To stabilize our planet's climate, we need to find ways to kick the carbon habit altogether. In the study, to be published in Geophysical Research...
