Ancient Earth Was Warmer Due To Forest Emissions And Wildfires
2014-02-06 04:13:00

[ Watch the Video: Wildfires Heated Up The Early Earth ] Lee Rannals for redOrbit.com - Your Universe Online According to a new study published in the journal Geophysical Research Letters, wildfires could explain why the Earth was so hot three million years ago. Researchers at Yale University found that volatile compounds released by ancient Earth’s forests and smoke from wildfires caused more global warming than atmospheric levels of carbon dioxide. This study provides evidence...

Tropical Cyclone Edna Brushes By New Caledonia
2014-02-05 13:17:18

NASA NASA's Aqua satellite spotted two storms in one image in the Southern Pacific Ocean as Tropical Cyclone Edna brushes by New Caledonia and an extra-tropical storm lingers west of New Zealand. New Caledonia warnings were still in effect on February 5 as Edna continues moving along the southwestern part of the island. An Amber Alert was in effect for the whole southern province as well as the community of Canala and a Yellow Alert was in effect for the rest of the territory. NASA's...

Climate Change Could Cause Trillions In Damage To World's Coastal Regions
2014-02-05 10:28:40

University of Southampton New research predicts that coastal regions may face massive increases in damages from storm surge flooding over the course of the 21st century. According to the study published in the Proceedings of the National Academy of Sciences, global average storm surge damages could increase from about $10-$40 billion per year today to up to $100,000 billion per year by the end of century, if no adaptation action is taken. The study, led by the Berlin-based think-tank...

El Nino Could Be Light at End of Tunnel Las Vegas, Nev. (PRWEB) February 04, 2014 Winter is only half over, and the extreme cold has already broken thousands of records in the Central and Eastern U.S. Meanwhile, the Western U.S. is breaking drought records. Both are caused by a dynamic jet stream shifting the cold far north in the West and far south in the East says Evelyn Browning-Garriss, noted climatologist and author, who predicted this extremely cold winter and California drought in...

Mid-Level Solar Flare Emitted By Sun Feb. 3, 2014
2014-02-04 12:12:58

Karen C. Fox - NASA's Goddard Space Flight Center, Greenbelt, Md. The sun emitted a mid-level solar flare, beginning at 11:57 p.m. EST on Feb. 3, 2014, and peaking at midnight EST. NASA released images of the flare as captured by NASA's Solar Dynamics Observatory. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere...

Demographic changes this century mean that elderly will be most vulnerable to impact of climate change The number of annual excess deaths caused by hot weather in England and Wales is projected to surge by 257% by the middle of the century, as a result of climate change and population growth, concludes research published online in the Journal of Epidemiology and Community Health. The elderly (75+) will be most at risk, particularly in the South and the Midlands, the findings suggest....

NASA's Aqua Satellite Tracking System 94P Near Queensland
2014-02-04 08:05:51

NASA A tropical low pressure area known as "System 94P" has tracked across western Queensland and moved into the Gulf of Carpentaria between Karumba and Gilbert River Mouth on February 3 as NASA's Aqua satellite passed overhead. System 94P continues to struggle to organize into a tropical depression, and the Australian Bureau of Meteorology or ABM has dubbed the storm "Fletcher." ABM expects the low pressure area to bring heavy rain to the Gulf Country district, mostly to coastal parts...

Can Nature Selectively Buffer Human-caused Global Warming?
2014-02-03 09:57:45

The Hebrew University of Jerusalem Can naturally occurring processes selectively buffer the full brunt of global warming caused by greenhouse gas emissions resulting from human activities? Yes, find researchers from the Hebrew University of Jerusalem, Johns Hopkins University in the US and NASA's Goddard Space Flight Center. As the globe warms, ocean temperatures rise, leading to increased water vapor escaping into the atmosphere. Water vapor is the most important greenhouse gas, and...

Urban Heat Island
2013-04-02 15:35:21

An urban heat island (UHI) is a metropolitan area that is drastically warmer than its surrounding rural areas because of human activities. The phenomenon was first looked into and described by Luke Howard during the 1810s, although he wasn’t the one to name the phenomenon. The difference in temperature is normally bigger at night as opposed to during the day, and it most obvious when winds are weak. Seasonally, UHI is seen during the summer and the winter. The key cause of the urban heat...

Desertification
2013-04-02 09:46:56

Desertification is a form of land degradation in which a comparatively dry land area becomes more and more arid, normally losing its bodies of water along with its wildlife and vegetation. This is a result of a variety of factors, such as climate change and human activities. Desertification is an important global, ecological, and environmental issue. There is substantial controversy over the proper definition of the term “desertification”. The most broadly accepted of these is that of...

Climate Change
2013-04-01 11:05:27

Climate change is a substantial and lasting change in the statistical distribution of weather patterns over periods of time ranging from decades to millions of years. It might be a change in the average weather conditions, or in the distribution of weather around the average conditions. Climate change is a result of factors that include oceanic processes, biotic processes, variations in solar radiation received buy Earth, volcanic eruptions, and plate tectonics, and human induced alterations...

Weather Model Discussion:  How To Use Surface Dew-points For Weather Forecasting Purposes
2013-01-29 08:53:47

Surface Dew-points can play a huge role in weather forecasting. The first such role is that it helps determine the amount of moisture in the atmosphere for a given point. If we look at the current dew-point map above from January 28, 2013 we can note several things of interest. First, if we look at where the black circle is around the number 70, we can make note that this air right off the coast of Texas is at a dew point of 70F. The temperature outside must be above 70F, because the...

Weather Education - Air Mass Thunderstorms
2013-01-13 10:30:47

Air mass thunderstorms are found in marine time tropical air. In short they are also known as MT Thunderstorms. Air mass thunderstorms represent what is known as the common three stage thunderstorm development. This means that an air mass thunderstorm goes through the stages of Cumulus which is represented by the updrafts only being present; secondly it moves into the mature stage where it has both updrafts and downdrafts; finally it goes into the dissipating stage where you see only the...
