greenhouse gas bulletin
2014-09-09 07:28:44

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...

long term warming trend
2014-03-11 12:20:13

WASHINGTON, March 11, 2014 /PRNewswire-USNewswire/ -- A new NASA study shows Earth's climate likely will continue to warm during this century on track with previous estimates, despite the recent slowdown in the rate of global warming. This research hinges on a new and more detailed calculation of the sensitivity of Earth's climate to the factors that cause it to change, such as greenhouse gas emissions. Drew Shindell, a climatologist at NASA's Goddard Institute for Space Studies in New...

Say researchers from the Hebrew University, US and Australia The warming effect of human-induced greenhouse gases is a given, but to what extent can we predict its future influence? That is an issue on which science is making progress, but the answers are still far from exact, say researchers from the Hebrew University of Jerusalem, the US and Australia who have studied the issue and whose work which has just appeared in the journal Science. Indeed, one could say that the picture is a...

Climate Change Plateau Due To Montreal Protocol
2013-11-11 14:29:39

Lee Rannals for redOrbit.com - Your Universe Online Researchers writing in the journal Nature Geoscience say CFC gases have had an impact on the rise in global temperatures. Scientists believe CFC gases are responsible for a massive hole in the ozone layer, but the latest study links the ban of these gases to a slowdown in temperature increases since the mid 1990s. The standstill of global temperature rises since 1998 has been used as a key argument by some to show the impacts of global...

Study Finds Human Activity Affects Vertical Structure Of Atmospheric Temperature
2013-09-17 13:05:39

Lawrence Livermore National Laboratory Human influences have directly impacted the latitude/altitude pattern of atmospheric temperature. That is the conclusion of a new report by scientists from Lawrence Livermore National Laboratory and six other scientific institutions. The research compares multiple satellite records of atmospheric temperature change with results from a large, multi-model archive of simulations. "Human activity has very different effects on the temperature of the...

Understanding A Century Of Human Impact On Arctic Climate
2013-09-12 13:02:22

Desert Research Institute The Arctic is the most rapidly warming region of the globe, but warming has not been uniform and the drivers behind this warming not fully understood even during the 20th century. A new study authored by Canadian and American investigators and published in Scientific Reports, a primary research publication from the publishers of Nature, suggests that both anthropogenic and natural factors – specifically sulphate aerosols from industrial activity and volcanic...

Wildfire Climate Interactions Pose Long Term Problems
2013-05-22 10:46:39

redOrbit Staff & Wire Reports - Your Universe Online The US Forest Service voiced its concern on Tuesday over the atmospheric effects of wildfire emissions on climate change, saying the issue is of great importance to scientists and policymakers alike. The warnings are particularly important given recent projections of an average 50-percent increase in wildfires across the US — and over 100 percent in some areas of the West — by 2050, the Service said. The agency...

Carbon dioxide (CO2) levels reported to have reached 400 ppm at Mauna Loa Observatory sent climate change activists like James Hansen, Al Gore, 350.org and Scientific American into a frenzy but Friends of Science say solar and ocean cycles are the main drivers of climate change, not CO2. With no global warming in 16 years despite a rise in CO2, the role of declining water vapor in upper atmosphere partially negates the ℠heat-trapping´ effect of CO2. Calgary, Alberta, Canada (PRWEB)...

How Solar Activity Affects Our Planet
2013-01-10 11:02:17

NASA Science In the galactic scheme of things, the Sun is a remarkably constant star. While some stars exhibit dramatic pulsations, wildly yo-yoing in size and brightness, and sometimes even exploding, the luminosity of our own sun varies a measly 0.1% over the course of the 11-year solar cycle. There is, however, a dawning realization among researchers that even these apparently tiny variations can have a significant effect on terrestrial climate. A new report issued by the National...
