Scientists say Pollution caused global warming hole delayed climate change over eastern United States

Reduction in air pollution from coal fired power stations due to environmental regulations since the 1980s has increased regional global warming in the Central and Eastern United States. Climate scientists from the Harvard School of Engineering and Applied Sciences (SEAS) found that particulate pollution, particularly from coal fired power stations, caused a global warming hole, or a large cold patch reducing temperatures by up to 1 degree C in the region, particularly lowering maximum temperatures in Summer and Autumn.

Oceans at high risk of unprecedented Marine extinction scientists warn

A report issued last week from the International Programme on the State of the Ocean (IPSO) has strongly warned of the damage to the health of the world's oceans and marine life from several factors including the impacts of climate change. The report warned that if the current business as usual trajectory of damage continues "that the world's ocean is at high risk of entering a phase of extinction of marine species unprecedented in human history."

Greenpeace Australia targets BHP Billiton over Carbon Pollution

A Busy week for the activists of Greenpeace Australia who did a banner drop outside BHP Billiton headquarters in Melbourne on Monday and followed it up midweek with erecting a Pollution Tax Collection Point at BHP’s Mount Arthur Mine in the Hunter Valley of New South Wales holding up a BHP coal train temporarily.

Mechanized Monstrosities Of Fossil Fuel Extraction

In a world still reliant on fossil fuels for the vast majority of our
energy, we consume vast quantities of oil, coal, and other non-renewable
resources.  The machines that enable us to get at these resources are
necessarily gigantic. In fact, they are among some of the largest
machines on the planet. A good way to wrap your head around the enormity
