Life Cycle Cost of Coal Power in the U.S. - $500 Billion/Year

A new Harvard University study examines the life cycle cost of coal power including all the resulting environmental and wow it's great buy levitra online health expenses and found that although the coal itself might be cheap, the price of generating power from it is not.  The study found that coal power actually costs the U.S. somewhere between $345 billion and $500 billion each year.

The study says that if all of those expenses were included in people's electricity bills, it would double to triple the cost of coal power, adding $0.09 - $0.27 per kWh, making it no longer the cheapest source of electricity, but one of buying cialis the most expensive.

Some of the hidden expenses outlined in the study are elevated rates of cancer and other diseases in coal-mining regions, environmental damage to those areas (including water and air pollution), loss of tourism dollars and costs related to soft levitra climate change.

The full study titled "Full cost accounting for the cialis from canadian pharmacy life cycle of coal" will be published in the Annals of the New York Academy of Sciences soon.

Amazon Drought Caused More Emissions than U.S. Last Year

A huge drought in the Amazon rain forest last year may have caused the release of more emissions than the U.S. is responsible for in a year.

The usually carbon-hungry forest is a major CO2 sink, but when a drought strikes and cost of propecia vegetation dies, all of that carbon that was stored gets released, and in the case of the major droughts that occurred last year and in 2005, the impact is cheap viagra from mexico pretty big.

In fact, a study published yesterday in the journal Science concludes that the Amazon would not absorb the usual 1.5 billion metric tons of CO2 from the atmosphere in both 2010 and 2011 and the dying vegetation would result in a release of 5 billion metric tons of CO2, meaning a total of 8 billion metric tons of CO2 added to the canadianpharmacy atmosphere.  In 2009, the U.S. was responsible for 5.4 billion metric tons of CO2 from fossil fuel use.

The scariest part of this is that climate change is causing more weather extremes like droughts, which in turn are causing more greenhouse gases to be released into the atmosphere, creating a vicious cycle.

UK's Greenhouse Gas Emissions Fell by 8.7% in 2009

The UK's greenhouse gas emissions fell by 8.7 percent from 2008 to 2009, with CO2 falling 9.8 percent -- the biggest dip since 1980.  While this is great news, the reason is unfortunately not a major growth in renewable energy of environmental policies, but the correlating economic recession.

As the UK economy sank into a recession, heavy-emitting industries like construction or transport lost a lot of business and subsequently stopped emitting so much greenhouse gas.  A similar benefit to the economic recession happened in China where air pollution dramatically decreased with the downturn.

The good news is that if the UK government and corporations capitalize on canadain viagra this head start towards their emission-reduction goals, hitting the target of a 35 percent reduction by 2020 and more aggressive targets later on will be much easier and possibly ahead of approved viagra pharmacy schedule.

Greenland's Melting Season Lasted 50 Days Longer than Average in 2010

Researchers found that Greenland's annual melting season lasted 50 days longer than average last year when compared to the years between 1979 and 2009.  Their work was published in the latest issue of Environmental Research Letters.

Higher than normal surface temperatures occurring not just in the summer, but also in the spring and late winter, caused the melting season to kick off early and take longer to end.  Because of the extension of melting days, the country experienced record surface ice melt, record water runoff from the ice sheet and a record number of days of bare ice without snow.

The researchers analyzed satellite data including surface temperatures, satellite estimates of melting, as well as ground observations from weather stations on the ice sheet.  They're attempting to use this information to improve computer models that can predict how the generic viagra cost ice will behave under future warming conditions and estimate sea level rise.

One of the most important things the researchers observed from the study was that the relationship between temperature and melt was not linear -- it can be exponential.  As snow melts, it reveals older less reflective snow and eventually even less reflective bare ice, both of which absorb more heat and accelerate melting and ultimately extend the melt season.

Obama Administration Wants Arctic Seals on Endangered Species List

The Obama administration has proposed adding six different subspecies of Arctic seals to the endangered species list because of the threat they're facing from shrinking sea ice.  NOAA made the proposal for those seals to be listed as threatened on Friday, and if approved, the seals would be the second animals after polar bears listed for reasons purely caused by climate change.

The listings include four subspecies of ringed seals found in the Arctic Basin and the North Atlantic and buy levitra in canada two subspecies of bearded seals found in the North Pacific (including Russia and Alaska).  Vanishing sea ice was the primary  given for all the seals.

NOAA said that the changes to the seals' habitats was a clear indication that climate change was occurring and that the listing will improve the odds for those animals.  The listing is open for public comment and has a year to be finalized.
