Record Carbon Dioxide Levels In 2012, Methane Off The Charts
2013-11-07 12:50:28

Alan McStravick for redOrbit.com - Your Universe Online If you are a fan of random violence occurring worldwide, a new report out this week is right up your alley. While we learned earlier this year that 2012 was the ninth warmest year since 1880, this week we were greeted with news that greenhouse gases, like carbon dioxide, methane and nitrous oxide, hit record highs in that same year. Specifically, carbon dioxide levels have increased a full 41 percent since the start of the...

Vital Precipitation Could Be Lost Through Climate Geoengineering
2013-11-01 07:38:38

[ Watch the Video: Monsoonal Rains Could Shrink Due To Geoengineering ] April Flowers for redOrbit.com - Your Universe Online A new study, led by scientists from the National Center for Atmospheric Research (NCAR), shows that although a significant build-up in greenhouse gases in the atmosphere would alter worldwide precipitation patterns, a widely discussed technological approach to reduce future global warming would also interfere with rainfall and snowfall. The findings, published...

Forest Ecosystems Keep The Earth From Cooking
2013-10-17 04:10:12

April Flowers for redOrbit.com - Your Universe Online According to a new study led by Princeton University, enhanced growth of the Earth's plants during the 20th century has caused a significant slowdown of the Earth's transition to being "red-hot." This study, the first to specify the extent to which plants have prevented climate change since pre-industrial times, found that land ecosystems have kept the planet cooler by absorbing billions of tons of carbon, especially during the past 60...

Arctic Tunda May Add To Greenhouse Gas Emissions
2013-10-10 13:11:36

Brett Smith for redOrbit.com – Your Universe Online Arctic tundra is often thought of as a barren wasteland that has no direct bearing on global events. However, a team of Scandinavian scientists is warning that the tundra could be a significant contributor to greenhouse gas emissions if temperatures in the Arctic continue to rise. "The soil below the tundra contains very large quantities of carbon – more than twice as much as is present in the planet's entire atmosphere,”...

Young Sun Paradox Early Climate
2013-10-04 13:46:54

Brett Smith for redOrbit.com - Your Universe Online When life originated on Earth between 3.8 and 2.4 billion years ago during the Archean era, our sun was only functioning at about 75 percent of its current power. With this ‘low wattage’ sun, the Earth should have been covered in glaciers, yet scientists have found no evidence of this taking place. In a new study published recently by the journal Science, a team of international researchers’ analysis of rock samples dating back...

Earth's Oceans In Greater Danger Than We Thought
2013-10-03 13:28:06

[ Watch the Video: Oceans In Peril? ] Lee Rannals for redOrbit.com - Your Universe Online A panel of marine scientists claims that the Earth's oceans are under an even greater threat than previously thought. The International Programme on the State of the Ocean (IPSO) conducted a review on ocean degradation based on the rate, speed and impacts of climate change on the Earth's waters. The panel found that the oceans are facing even greater, faster and more imminent changes than once...

Greenhouse gases continue to affect our planet. (PRWEB) September 27, 2013 Turning on the heat or driving to the market are activities we as Americans may take for granted, but worldwide, studies indicate only China uses more fossil fuels and emits more greenhouse gases than the U.S. These seemingly innocuous activities, when taken as a whole, could cause damaging long-term consequences for the environment and ecosystem. A growing awareness of the relationship between fossil fuel burning...

Foraminifera Fossils Reveal An Ice-Free Late Cretaceous Period
2013-09-25 05:04:54

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...

Ocean Water Vertically Mixes As It Rushes Over Undersea Mountains
2013-09-19 07:58:02

April Flowers for redOrbit.com - Your Universe Online In the ocean near Antarctica, an international research team has solved the mystery of how deep and mid-depth ocean waters are mixed. The study, published in the journal Nature, reveals that sea water mixes dramatically as it rushes over undersea mountains in Drake Passage - the channel between the southern tip of South America and the Antarctic continent. This mixing of oceanic water layers is vital in the regulation of the Earth's...

Receding Ice Exposes Seawater To Carbon Dioxide, Driving Ocean Acidification In The Arctic Ocean
2013-09-13 12:12:21

University of South Florida (USF Health) Acidification of the Arctic Ocean is occurring faster than projected according to new findings published in the journal PLoS One. The increase in rate is being blamed on rapidly melting sea ice, a process that may have important consequences for health of the Arctic ecosystem. Ocean acidification is the process by which pH levels of seawater decrease due to greater amounts of carbon dioxide being absorbed by the oceans from the atmosphere....

Earth's Atmosphere
2004-10-19 04:45:44

Earth's Atmosphere -- Earth's atmosphere consists of nitrogen (78.1%) and oxygen (20.9%), with small amounts of argon (0.9%), carbon dioxide (variable, but around 0.035%), water vapor, and other gases. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation and reducing temperature extremes between day and night. 75% of the atmosphere exists within 11km of the planetary surface. Temperature and the Atmospheric Layers The temperature of the Earth's atmosphere...
