As Californians Pump Groundwater, Land Sinks and Aquifers Shrink

Publication: NBC News   Date: July 15, 2014   View Article

So much water is being pumped from the ground in parched California that the land is sinking, according to scientists.

The more Californians rely on groundwater, the worse these problems will get, experts across industry, government, and academia say. But, they said, the pumping is likely to continue given a confluence of factors that range from urban population growth to an expanding agricultural industry.

Frogs Get Their Shots: Vaccination May Curb Lethal Fungus

Publication: NBC News   Date: July 9, 2014   View Article

Around the world, the rapid spread of a pathogenic fungus has sent frogs and other amphibians hopping toward extinction. Hope for their survival may come in the form of vaccination programs similar to those that protect humans from contagious diseases, according to a new study.

No, this doesn’t mean that newborn tadpoles will be paying a visit to the veterinarian for a round of shots, or that conservationists with mini-syringes will be mucking through rain forests in search of frogs. But the reality isn’t all that different.

Hundreds of amphibians already have been removed from habitats contaminated with the fungus Batrachochytrium dendrobatidis, which causes chytridiomycosis — the fungal disease implicated in the global amphibian decline. One route is to vaccinate these captive-bred amphibians, explained Jason Rohr, an ecologist at the University of South Florida and the study’s senior author.

Neonicotinoid Pesticide Linked to Decline of Birds (and Bees)

A controversial agricultural insecticide that has been implicated in the collapse of bee colonies around the world also appears to be causing bird populations to drop, according to a new study. The insecticides known as neonicotinoids are designed to attack the central nervous system of insects that devour crops, but only about 5 percent of the chemical compound stays on the plant. The rest leaches into the soil and water, where it does its magic on other bugs, the researchers said.

That’s Nuts: Almond Boom Strains California Water Supply

Publication: NBC News   Date: June 22, 2014   View Article

Asia’s love of nuts is draining California dry.

Amid one of the worst droughts in the state’s history, farmers are scrambling to find enough water to irrigate lucrative almond trees they planted after abandoning other, less thirsty crops.

Why’s there such a market for California nuts? As incomes in countries such as China, South Korea, and India have risen, so has demand for nuts that formerly were out of reach for many Asians. Added to the mix are Wall Street firms who, smelling a quick buck, are paying top dollar for vegetable farms and converting them to orchards.

Cough, Cough: Climate Change May Worsen Air Pollution

Publication: NBC News   Date: June 22, 2014   View Article

Residents of bulging metropolises around the world should brace for an increase in stagnant, polluted air that hangs around for days as a result of climate change-related shifts in wind and rainfall patterns, according to a new study.

The findings highlight one way global warming can compromise human health, which is a major thrust behind the U.S. Environmental Protection Agency’s recently proposed plan to curb power plant carbon emissions 30 percent by the year 2030, said Janice Nolen, an assistant vice president at the American Lung Association in Washington.

Insurer’s Message: Prepare for Climate Change or Get Sued

Publication: NBC News   Date: June 6, 2014   View Article

To insurance companies, there’s no doubt that climate change is here: They are beginning to file lawsuits against small towns and cities who they say haven’t prepared for the floods and storms that will cost the companies billions in payments.

Earlier this week, the U.S. arm of a major global insurance company backed away from an unprecedented lawsuit against Chicago and its suburbs for failing to prepare for heavy rains and associated flooding it claimed were fueled by global warming. While legal experts said the case was a longshot, its withdrawal didn’t alter the message it contained for governments: prepare now for climate change or pay the price.

New Carbon Rules: Here’s How States Could Be Forced to Cut Emissions

Publication: NBC News   Date: June 2, 2014   View Article

In a bid to stave off the dire effects of global warming on human health and the environment, the White House on Monday unveiled a new plan to slash carbon emissions from the power sector by 30 percent below 2005 levels by the year 2030.

“That’s like cancelling out annual carbon pollution from two-thirds of all cars and trucks in America,” Gina McCarthy, the administrator of the U.S. Environmental Protection Agency, said in announcing the new rules.
