Blue Cut Fire in California spreads quickly
August 18, 2016 01:43 PM - NASA/GODDARD Space Flight Center via EurekAlert!

The Blue Cut Fire, just outside of Los Angeles, is a quickly growing fire that is currently an imminent threat to public safety, rail traffic and structures in the Cajon Pass, Lytle Creek, Wrightwood, Oak Hills, and surrounding areas. An estimated 34,500 homes and 82,640 people are being affected by the evacuation warnings that have been issued. 

Mapping the health threat of wildfires under climate change in US West
August 16, 2016 03:08 PM - Yale School of Forestry & Environmental Studies via ScienceDaily

A surge in major wildfire events in the U.S. West as a consequence of climate change will expose tens of millions of Americans to high levels of air pollution in the coming decades, according to a new Yale-led study conducted with collaborators from Harvard.

The researchers estimated air pollution from past and projected future wildfires in 561 western counties, and found that by mid-century more than 82 million people will experience "smoke waves," or consecutive days with high air pollution related to fires.

The regions likely to receive the highest exposure to wildfire smoke in the future include northern California, western Oregon, and the Great Plains.

Threat of wildfires expected to increase as global temperatures rise
August 12, 2016 04:01 PM - United Nations Office for Disaster Risk Reduction

The United Nations Office for Disaster Risk Reduction (UNISDR) has warned that wildfires could become more frequent and more destructive as global temperatures rise and drought conditions plague many regions of the world.

“Last year was the hottest year on record and was above average for the number of reported major droughts and heatwaves. This year we are seeing a similar pattern with new temperature records being set on a monthly basis,” UNISDR chief Robert Glasser said yesterday in a news release issued by the Office.

Feds Say California's Endangered Channel Islands Foxes Are Recovered
August 11, 2016 03:48 PM - Center for Biological Diversity

The U.S. Fish and Wildlife Service today announced the successful recovery of three out of four unique subspecies ofisland fox on San Miguel, Santa Rosa and Santa Cruz islands, removing them from the endangered species list. The agency also upgraded the protection status of the Santa Catalina Island fox — the fourth subspecies — from “endangered” to “threatened” to reflect its status improvement.

"Because they evolved separately on the islands for 16,000 years, these adorable little foxes are some of the only carnivores endemic to California,” said Jeff Miller with the Center. “They were on the brink of extinction just 12 years ago when they were protected under the Endangered Species Act. Now, thanks to successful reintroduction and recovery efforts, numbers of foxes are way up and threats have been reduced."

Galápagos faces first-ever bird extinction
August 10, 2016 02:34 PM - California Academy of Sciences via EurekAlert!

Scientists have discovered a new species of colorful songbird in the Galápagos Islands, with one catch: it's extinct. Researchers from the California Academy of Sciences, San Francisco State University (SFSU), the University of New Mexico (UNM), and the San Francisco Bay Bird Observatory (SFBBO) used molecular data from samples of museum specimens to determine that two subspecies of Vermilion Flycatchers, both found only in the Galápagos, should be elevated from subspecies to full species status. One of these newly recognized species--the characteristically smaller San Cristóbal Island Vermilion Flycatcher--hasn't been seen since 1987 and is considered to be the first modern extinction of a Galápagos bird species. The findings were published online earlier this May in the journal Molecular Phylogenetics and Evolution.

Why we need to keep rivers cool with riverside tree planting
August 10, 2016 02:21 PM - Ecologist reporter, Ecologist

With some climate predictions warning that river water temperatures will exceed safe thresholds for river fish, the Keep Rivers Cool (KRC) campaign is calling for more riverside tree planting.

Fish in Britain's rivers are under threat from warmer waters. Cold-water species such as Atlantic salmon and brown trout, are struggling to cope as climate change brings significant increases in temperature.

Today there's a call for urgent action to Keep Rivers Cool by planting broadleaf native trees alongside river banks, creating dappled shading and stopping water from warming up.

Shade can reduce temperatures in small rivers by on average 2- 3C compared to un-shaded streams; and by more on hot summer days.

A Troubling Snag in the Comeback of the California Condor
August 8, 2016 04:40 PM - Matt Simon via Wired.com

IN THE EARLY ’80s, the California condor almost scavenged its way to extinction. The grisly-looking birds survive off the remains of animals, often leftovers shot by hunters. But those hunters often used lead ammunition. Condors were dying of lead poisoning, their numbers dropping as low as 22.

In one of conservation’s greatest success stories, a frantic captive breeding program brought the huge, glorious scavenger roaring back; today, the condors number close to 450, over half of which are wild. While an outright ban on lead ammunition won’t kick in until 2019, aggressive public education has helped safeguard the species—inland at least. But scientists have found a new threat to the reestablished condors: extremely high levels of mercury and the pesticide DDT in the birds’ blood. This time, it’s an appetite for marine mammal flesh that may threaten the condor.

Lake Tanganyika fisheries declining from global warming
August 8, 2016 03:47 PM - University of Arizona via EurekAlert!

The decrease in fishery productivity in Lake Tanganyika since the 1950s is a consequence of global warming rather than just overfishing, according to a new report from an international team led by a University of Arizona geoscientist.

The lake was becoming warmer at the same time in the 1800s the abundance of fish began declining, the team found. The lake's algae - fish food - also started decreasing at that time.

Boats Are Killing Manatees in Record Numbers
August 8, 2016 07:04 AM - Alicia Graef, Care2

Manatee advocates are raising concerns about the number of these gentle giants who have been killed in Florida this year. They hope that increased vigilance and other measures will help keep this from being the worst year on record.

The Florida Fish and Wildlife Conservation Commission (FWC) has already counted 71 manatees killed by boats as of July 22. The numbers are already higher than they were for the same period in 2009, which was the deadliest year on record with a total of 97 deaths.
