The world is hurtling towards an era when global concentrations of carbon dioxide never again dip below the 400 parts per million (ppm) milestone, as two important measuring stations sit on the point of no return.

The news comes as one important atmospheric measuring station at Cape Grim in Australia is poised on the verge of 400ppm for the first time. Sitting in a region with stable CO2 concentrations, once that happens, it will never get a reading below 400ppm.

Global Warming Cited as Wildfires Increase in Fragile Boreal Forest

The boreal region stretches across the Northern Hemisphere through Alaska, Canada, Scandinavia and Russia. Boreal forests are increasingly affected by fire and climate change.

Sources: Natural Resources Canada; Alberta Agriculture and Forestry; U.S. Geological Survey; University of Maryland - By The New York Times

Scientists say the near-destruction of Fort McMurray last week by a wildfire is the latest indication that the vital boreal forest is at risk from climate change.

nytimes.com - by JUSTIN GILLIS and HENRY FOUNTAIN - May 10, 2016

Scientists have been warning for decades that climate change is a threat to the immense tracts of forest that ring the Northern Hemisphere, with rising temperatures, drying trees and earlier melting of snow contributing to a growing number of wildfires.

The near-destruction of a Canadian city last week by a fire that sent almost 90,000 people fleeing for their lives is grim proof that the threat to these vast stands of spruce and other resinous trees, collectively known as the boreal forest, is real. And scientists say a large-scale loss of the forest could have profound consequences for efforts to limit the damage from climate change.

Lack of Zika-Specific Test Creates Dilemma for Some Pregnant Women

Washington - Pregnant women who’ve traveled to Latin America and the Caribbean are advised to be tested for the Zika virus afterward. But medical researchers have discovered there’s a problem with that advice: Some diagnostic tests will return positive results even when a person hasn’t contracted Zika.

That ambiguity can force pregnant women who fear giving birth to babies with severe brain damage to make life-changing decisions based on incomplete information.

The discovery by Zika researchers that current antibody tests don’t distinguish between Zika and dengue, another mosquito-borne virus, is the latest twist in the scientific world’s confrontation with a virus long thought relatively harmless but now thought able to cause serious birth defects as well as life-threatening complications in adults.

The rout in crude prices is snowballing into one of the biggest avalanches in the history of corporate America, with 59 oil and gas companies now bankrupt after this week's filings for creditor protection by Midstates Petroleum and Ultra Petroleum.

The number of U.S. energy bankruptcies is closing in on the staggering 68 filings seen during the depths of the telecom bust of 2002 and 2003, according to Reuters data, the law firm Haynes & Boone and bankruptcydata.com.

Millions of drivers use Waze, a Google-owned navigation app, to find the best, fastest route from point A to point B. And according to a new study, all of those people run the risk of having their movements tracked by hackers.

Researchers at the University of California-Santa Barbara recently discovered a Waze vulnerability that allowed them to create thousands of “ghost drivers” that can monitor the drivers around them—an exploit that could be used to track Waze users in real-time.

Mayor de Blasio Announces Three Year, Five-Borough Plan to Protect New Yorkers from the Zika Virus

      

City’s Zika action plan enhances mosquito surveillance and control - Expands testing of humans and mosquitos, and launches public awareness campaign

nyc.gov - April 18, 2016

NEW YORK––Marking the start of mosquito season, Mayor de Blasio today detailed a three-year, five-borough plan to protect New Yorkers and prevent the spread of the Zika virus in New York City.

“We are doing all we can to target the mosquito that could transmit Zika here in the city, and building the capacity to respond to every possible scenario, no matter how unlikely,” said Mayor Bill de Blasio. “We will spare no effort to protect pregnant New Yorkers from the devastating consequences of Zika, and we ask New Yorkers to help us by taking simple steps to get rid of standing water where mosquitos can breed. We also ask pregnant women who may have been exposed to Zika to talk to their doctors about getting tested.”

Leak worsens in massive Hanford tank holding nuclear waste

A leak in a massive nuclear waste storage tank at the Hanford Site has expanded significantly, KING 5 learned this weekend.

After leak detector alarms sounded early Sunday morning, crews at Hanford lowered a camera into the two-foot-wide space between the tank's inner and outer walls. They discovered 8.4 inches of radioactive and chemically toxic waste has seeped into the annulus.
