Forests may not help mitigate carbon dioxide pollution thanks to an uptick in CO2 emissions from decomposition

 

As higher levels of carbon dioxide permeate the Earth's atmosphere, scientists have long counted on forests -- which, as individual trees, grow larger in carbon-rich environments -- to soak up some of the excess.

But after nearly a decade and a half of observing forest ecosystems in controlled settings, scientists now see evidence that elevating carbon levels may cause forests to release as much extra carbon as they absorb. ... Read more about Higher CO2 Levels in Atmosphere May Speed Soil Emissions

water ocean pollution

There are several causes of ocean pollution including oil pollution, marine debris, toxic materials, and ocean dumping and mining. Oil pollution is not only caused by large devastating tanker spills, it is also caused through runoff from land and industrial wastes which find their way to the ocean through drains. Other causes include intensive farming, septic tank, pesticide, animal dung, household waste, water table, waste water, nuclear waste... ... Read more about water ocean pollution

Mountaintop's Removal's Effect on Humans and the Economy

There’s a common saying in Appalachia: what we do to the land, we do to the people. Recently, 21 peer-reviewed scientific studies have confirmed the truth of those words. Not only has mountaintop removal permanently destroyed more than 500 Appalachian mountains, but people living near the destruction are 50% more likely to die of cancer and 42% more likely to be born with birth defects compared with other people in Appalachia. ...

Climate change: Arctic passes 400 parts per million milestone
Show
Arctic monitoring stations show carbon dioxide levels are now above 400 parts per million. Carbon dioxide is the chief climate-change gas and stays in the atmosphere for 100 years. Before the Industrial Age, carbon dioxide levels were 275 ppm.

The world's air has reached what scientists call a troubling new milestone for carbon dioxide, the main global warming pollutant. ... Read more about Climate change: Arctic passes 400 parts per million milestone

The world's 10 most populous river basins will be vital for economic growth – but only if water shortage threat is tackled

Water is the very stuff of life, yet billions of people do not have access to a clean, reliable source. Changing that takes investment - public and private - so winning the economic argument about the value of such investment is very valuable. And a new report commissioned by HSBC makes the argument in a striking way. ... Read more about Rivers will generate a quarter of GDP by 2050, study shows
