Developing nations bear the brunt of extreme weather
November 13, 2013 09:40 AM - Bhrikuti Rai, SciDevNet
Haiti, the Philippines and Pakistan were the countries that suffered the most due to extreme weather events in 2012, according to the Global Climate Risk Index released yesterday at the UN Climate Change Conference in Warsaw, Poland.
Filipino delegate: no denying climate change now
November 13, 2013 09:24 AM - Jeremy Hance, MONGABAY.COM
Monday, the Filipino delegate to the ongoing climate summit, Naderev 'Yeb' Saño, dared climate change deniers to take a hard look at what's happening not just in the Philippines, but the whole world. Over the weekend, the Philippines was hit by what may have been the largest typhoon to ever make landfall: Typhoon Haiyan. Reports are still coming in days later; death tolls were initially estimated to be over 10,000 with whole cities simply swept away, but more recent reports are placing the death toll lower but still substantial.
Tiny islands with big climate change problems
November 12, 2013 02:25 PM - Jan Piotrowski, SciDevNet
Tiny island states that speck the vast swathe of the Pacific Ocean have a far greater importance in understanding global climate change than their tiny populations would suggest. This was the message given to delegates during a side event of the UN Framework Convention on Climate Change's 19th annual meeting in Warsaw today.

The deadly typhoon that swept through the Philippines was one of the strongest ever recorded. But storms nearly this powerful are actually common in the eastern Pacific. Typhoon Haiyan's devastation can be chalked up to a series of bad coincidences. Typhoons — known in our part of the world as hurricanes — gain their strength by drawing heat out of the ocean. Tropical oceans are especially warm, which is why the biggest storms, Category 4 and Category 5, emerge there. These storms also intensify when there's cool air over that hot ocean. "The Pacific at this time of year is very ripe and juicy for big typhoons," says Kerry Emanuel, a climate scientist at the Massachusetts Institute of Technology. "Once or twice a year we get a Category 5 typhoon out there."
NASA Releases Satellite Images of Typhoon Haiyan
November 11, 2013 04:10 PM - Editor, ENN
Typhoon Haiyan made landfall last week, causing much destruction in Southeast Asia. With death counts estimated to be in the thousands, this storm is one of the most powerful recorded typhoons to ever hit land and likely the deadliest natural disaster to hit the Philippines. So far, the typhoon is said to have affected at least 9.7 million people in 41 provinces. New satellite images obtained from NASA's Atmospheric Infrared Sounder (AIRS) instrument aboard NASA's Aqua spacecraft and the Indian Space Research Organization's OceanSAT-2 ocean wind scatterometer provide a glimpse into one of the most powerful storms ever recorded on Earth.
Transforming the Solar Discussion
November 11, 2013 01:08 PM - Robin Blackstone, ENN
The sun’s energy has been a central component of the renewable energy cache, including several harnessing technologies such as solar heating, photovoltaics, thermal, architecture and artificial photosynthesis. Researchers at the University of Cincinnati are bringing forth a new method of solar capture and storage called SmartLight that includes the use of electrofluidic cells in concert with embedded photovoltaics placed at the top of a building’s windows. These solar capture elements are then used to project light into the building through a continuous grid-strip of electrofluidic cells. Lead researcher, Jason Heikenfeld envisions these cell channels running across the top of a room and through room adjoining transom windows for distribution as needed within any of the office building’s rooms regardless of its position within the building.
Climate Linked to Atmospheric-River Storms
November 8, 2013 03:45 PM - Editor, ENN
It's not every day that the weatherman reports on atmospheric river storms...but we may be hearing the term more frequently now as researchers have linked climate in the Pacific Ocean and West Coast mountains to these distinctive storms. An atmospheric river is a narrow stream of wind, about a mile high and sometimes of hurricane strength. Crossing the warm tropical Pacific in a few days, it becomes laden with water vapor. A moderate-sized atmospheric river carries as much water as the Mississippi River dumps into the Gulf of Mexico in an average week! When the river comes ashore and stalls over higher terrain, the water falls as snow or rain.
Plan It for the Planet! November 15th America Recycles Day
November 8, 2013 10:16 AM - Robin Blackstone, ENN
So maybe America Recycles Day isn't as well known as Thanksgiving, New Years or the Fourth of July, but it is potentially becoming equally as significant for our planet's future! While our national recycling rate has increased each year for the past 30 years there is still great opportunity for recycling. America Recycles Day is the only nationally recognized day and community-driven awareness event dedicated to promoting and celebrating recycling in the U.S.
Relating the trees in the Amazon to west coast droughts
November 7, 2013 02:09 PM - Morgan Kelly, Princeton University
In research meant to highlight how the destruction of the Amazon rainforest could affect climate elsewhere, Princeton University-led researchers report that the total deforestation of the Amazon may significantly reduce rain and snowfall in the western United States, resulting in water and food shortages, and a greater risk of forest fires.
Tesla in the Mass Market
November 7, 2013 08:42 AM - MoveForward, Electric Forum
Tesla Motors is a company, which seems to go from strength to strength and indeed to all intents and purposes this is a company, which has dragged the electric vehicle market kicking, and screaming to the point of mass acceptance. Anybody who has even looked at electric vehicles will be well aware that Tesla began life at the top end of the luxury car market and once this particular niche was dominated the company began to look further down the electric car food chain.
