30 June 2016, NASA. Why a half-degree temperature rise is a big deal. The Paris Agreement, which delegates from 196 countries hammered out in December 2015, calls for holding the ongoing rise in global average temperature to “well below 2 °C above pre-industrial levels,” while “pursuing efforts to limit the temperature increase to 1.5 °C.” How much difference could that half-degree of wiggle room (or 0.9 degree on the Fahrenheit scale) possibly make in the real world? Quite a bit, it appears. The European Geosciences Union published a study in April 2016 that examined the impact of a 1.5 degree Celsius vs. a 2.0 C temperature increase by the end of the century, given what we know so far about how climate works. It found that the jump from 1.5 to 2 degrees—a third more of an increase—raises the impact by about that same fraction, very roughly, on most of the phenomena the study covered. Heat waves would last around a third longer, rain storms would be about a third more intense, the increase in sea level would be approximately that much higher and the percentage of tropical coral reefs at risk of severe degradation would be roughly that much greater. But in some cases, that extra increase in temperature makes things much more dire. At 1.5 C, the study found that tropical coral reefs stand a chance of adapting and reversing a portion of their die-off in the last half of the century. But at 2 C, the chance of recovery vanishes. Tropical corals are virtually wiped out by the year 2100. Read More here

29 June 2016, NASA, NASA maps California drought effects on Sierra trees. A new map created with measurements from an airborne instrument developed by NASA’s Jet Propulsion Laboratory, Pasadena, California, reveals the devastating effect of California’s ongoing drought on Sierra Nevada conifer forests. The map will be used to help the U.S. Forest Service assess and respond to the impacts of increased tree mortality caused by the drought, particularly where wildlands meet urban areas within the Sierra National Forest. After several years of extreme drought, the highly stressed conifers (trees that produce cones and are usually green year-round) of the Sierra Nevada are now more susceptible to bark beetles (Dendroctonus spp.). While bark beetles killing trees in the Sierra Nevada is a natural phenomenon, the scale of mortality in the last couple of years is far greater than previously observed. The U.S. Forest Service is using recent airborne spectroscopic measurements from NASA’s Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) instrument aboard NASA’s ER-2 aircraft, together with new advanced algorithms, to quantify this impact over this large region of rugged terrain. The high-altitude ER-2 aircraft is based at NASA’s Armstrong Flight Research Center, Edwards, California. Read More here
29 June 2016, Institute for Policy Studies. Free Trade Agreements Have Exacerbated a Humanitarian Crisis in Central America. Proposals like the Alliance for Prosperity Plan and the Trans-Pacific Partnership will only accelerate a race to the bottom for families in the Northern triangle of Latin America, Manuel Perez-Rocha said at the AFL-CIO conference on U.S. trade policy. U.S. trade negotiators continue to claim that free trade agreements help to support security, but in reality, they exacerbate the root causes of instability in the Mesoamerican region, IPS’s Manuel Perez-Rocha said in a speech at the AFL-CIO conference on U.S. trade policy. “Real security encompasses economic, human, financial, and political security,” he said. Today the Northern triangle of Latin America is one of the most dangerous places in the world. In Mexico alone, there are more than 27,000 people reported missing on top of the 100,000 killed in the so-called war on drugs, Perez-Rocha said. He explained that the origins of this crisis are rooted in structural adjustment policies that the IMF and the World Bank imposed on Central America to pave the way for free trade agreements like the North American Free Trade Agreement (NAFTA), the Central America Free Trade Agreement (CAFTA) and now the Trans-Pacific Partnership (TPP). “Instead of bringing prosperity, [NAFTA] took away domestic protections from Mexico’s food production, leading to greater food insecurity and the widespread loss of our agricultural livelihoods,” he said.

28 June 2016, DESMOG, Obama Admin Approved Over 1,500 Offshore Fracking Permits in Gulf of Mexico and Mainstream Media Has Ignored It. On June 24, the independent news website TruthOut broke a doozy of a story: the Obama Administration has secretly approved over 1,500 instances of offshore hydraulic fracturing (“fracking”) in the Gulf of Mexico, including during the Deepwater Horizon offshore spill disaster. Albeit released on a Friday, a day where many mainstream media reporters head out of the office early and venture to late-afternoon and early-evening Happy Hour specials at the bars, the TruthOut story has received deafening silence by the corporate-owned media apparatus. Google News, Factiva and LexisNexis searches reveal that not a single mainstream media outlet has covered the story. TruthOut got its hands on the story via documents provided by the Center for Biological Diversity (CBD). CBD explained inpress release that they “obtained the information following an agreement that settled a lawsuit challenging the federal Bureau of Ocean Energy Management’s and Bureau of Safety and Environmental Enforcement’s failure to disclose documents regarding the scope of offshore fracking in the Gulf under the Freedom of Information Act.” CBD also has published a list of all of the instances of offshore fracking in the Gulf of Mexico provided to it by BOEM, both inlist-form and in visual map form.
