Extreme weather already on increase due to climate change, study finds

climate changeExtreme heatwaves and heavy rain storms are already happening with increasing regularity worldwide because of manmade climate change, according to new research.

Global warming over the last century means heat extremes that previously only occurred once every 1,000 days are happening four to five times more often, the study published in Nature Climate Change said.

The oil and gas boom has devastated ecosystems across the US

oil and gas destroy ecosystemsDrilling for oil and gas has caused long-lasting damage to ecosystems across Canada and the US, according to a study published today. The findings lend new weight to longstanding concerns over the resurgence in domestic fossil fuel production, as well as the complex land use regulations that make environmental monitoring more challenging.

The paper, published in the journal Science, examines the impact of oil and gas production on terrestrial plant growth, using a metric called net primary production (NPP). NPP can be used to gauge the health of the ecosystem.

Fracking Increases Quakes in 8 States

fracking earthquakesSignificant strides in science have been made to better understand potential ground shaking from induced earthquakes, which are earthquakes triggered by man-made practices.

Earthquake activity has sharply increased since 2009 in the central and eastern United States. The increase has been linked to industrial operations that dispose of wastewater by injecting it into deep wells.

The U. S. Geological Survey (USGS) released a report today that outlines a preliminary set of models to forecast how hazardous ground shaking could be in the areas where sharp increases in seismicity have been recorded. The models ultimately aim to calculate how often earthquakes are expected to occur in the next year and how hard the ground will likely shake as a result. This report looked at the central and eastern United States; future research will incorporate data from the western states as well.

Oklahoma goes from two 3.0 quakes a year to two a day

Oklahoma earthquakesIn November of 2011, a magnitude 5.7 earthquake ripped through the small Oklahoma town of Prague, damaging more than a dozen homes and toppling a turret on a St. Gregory's University building in nearby Shawnee.

Study Links Texas Earthquake Swarm to Natural Gas Drilling

Texaas fracking linked to earthquakesWith real-time monitors, scientists have linked a swarm of small earthquakes west of Fort Worth, Texas, to nearby natural gas wells and wastewater injection.

"It's what we figured all along, it's not really new news to us," said Azle Mayor Alan Brundrett, "It's just confirming our suspicious that we've had."

In 84 days from November 2013 to January 2014, the area around Azle, Texas, shook with 27 magnitude 2 or greater earthquakes, while scientists at Southern Methodist University and the U.S. Geological Survey monitored the shaking. It's an area that had no recorded quakes for 150 years on faults that "have been inactive for hundreds of millions of years," said SMU geophysicist Matthew Hornbach.

Portland torn over $500m terminal: could fracking creep into a 'green' city?

Portland frackingPortland’s claim to lead US cities in combating climate change is under threat from plans to build a $500m terminal to export gas pumped from fracking in Canada.

Amid fears that Portland’s progressive, environmentally conscious image could be badly dented, the city is divided over whether exporting natural gas is part of the problem or the solution, in reducing carbon emissions.

Secrecy shrouds decade-old oil spill in Gulf of Mexico

Gulf Oil SpillA blanket of fog lifts, exposing a band of rainbow sheen that stretches for miles off the coast of Louisiana. From the vantage point of an airplane, it's easy to see gas bubbles in the slick that mark the spot where an oil platform toppled during a 2004 hurricane, triggering what might be the longest-running commercial oil spill ever to pollute the Gulf of Mexico.

Yet more than a decade after crude started leaking at the site formerly operated by Taylor Energy Company, few people even know of its existence. The company has downplayed the leak's extent and environmental impact, likening it to scores of minor spills and natural seeps the Gulf routinely absorbs.
