Climate Is The Hot Topic In Doha
2012-12-07 18:50:23

ESA ESA joined international delegates in Doha, Qatar, to discuss how satellite observations show our planet´s most sensitive areas reacting to climate change — and how this information is useful to the people living there. After almost two weeks of talks and negotiations, the UN Climate Change Conference has entered its final phase, when countries are represented mainly by their Ministers of Environment. During the first week of the ℠COP 18´ Conference of the...

Anthropogenic Climate Change Leads To Melting Glaciers And Rising Sea Level
2012-11-14 15:22:41

University of Innsbruck Between 1902 and 2009, melting glaciers contributed 11 cm to sea level rise. They were therefore the most important cause of sea level rise. This is the result of a new assessment by scientists of the University of Innsbruck. They numerically modeled the changes of each of the world´s 300 000 glaciers. Until 2100, glaciers could lead to an additional 22 cm of sea level rise. Since 1900 the global sea level has risen by approximately 20 cm. Melting glaciers...

Greenland Ice Melt Is "Unprecedented"
2012-07-25 06:04:10

Lee Rannals for redOrbit.com - Your Universe Online Satellites have revealed that Greenland's surface ice cover has melted this month more than any time in over 30 years of satellite observations. NASA said that nearly the entire ice cover of Greenland experienced some degree of melting at its surface this past month. Measurements from three independent satellites were analyzed by NASA and university scientists, who found that 97 percent of the ice sheet surface in Greenland thawed...

Thawing Arctic Cryosphere Releases Trapped Methane
2012-05-22 09:10:29

Brett Smith for RedOrbit.com The edges of glaciers and Arctic permafrost are where most of the evidence of global warming can be seen, but scientists have recently been traveling to these remote locations for a different reason. Researchers from the University of Alaska at Fairbanks just published a study in the online edition of Nature Geoscience showing that methane trapped under arctic lake ice for millions of years is now being released by the melting ice. The team used both aerial...

Image 1 - Warm Ocean Currents Cause Ice Loss In Antarctica
2012-04-26 04:55:01

Lee Rannals for RedOrbit.com [ Watch the Video ] An international team of scientists reported in the journal Nature on Thursday that warm ocean currents are the culprit behind recent ice loss in Antarctica. The team, lead by British Antarctic Survey, used 4.5 million measurements made by a laser instrument mounted on NASA's ICESat satellite to map the changing thickness of Antarctica's floating ice shelves. Of the 54 ice shelves they mapped, they revealed that 20 are melting...

Long-Term Study Sheds New Light On Climate Change Impact
2012-04-06 09:03:10

Scientists working on an ongoing study investigating the impact of climate change on various ecosystems have revealed that habitants dependent upon areas that typically experience ice and snow during the winter months are the most threatened by increasing global temperatures. The finding comes after more than three decades worth of study as part of the Long Term Ecological Research (LTER) Network, a National Science Foundation (NSF) initiative that features more than 1800 scientists and...

Thickest Parts Of Arctic Ice Cap Are Melting Faster
2012-03-01 04:33:50

[ Watch the Video ] A new NASA study revealed that the oldest and thickest Arctic sea ice is disappearing at a faster rate than the younger and thinner ice at the edges of the Arctic Ocean´s floating ice cap. The thicker ice, known as multi-year ice, survives through the cyclical summer melt season, when young ice that has formed over winter just as quickly melts again. The rapid disappearance of older ice makes Arctic sea ice even more vulnerable to further decline in the summer,...

Image 1 - Global Permafrost Zones Shown In High-res Google Earth Images
2012-02-21 10:07:16

Thawing permafrost will have far-reaching ramifications for populated areas, infrastructure and ecosystems. A geographer from the University of Zurich reveals where it is important to confront the issue based on new permafrost maps -- the most precise global maps around. They depict the global distribution of permafrost in high-resolution images and are available on Google Earth. Unstable cable-car and electricity pylons and rock fall — Alpine countries like Switzerland have already...


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
