Mosquitoes Genetically Modified To Crash Species That Spreads Malaria

NPR News - Environment - Mon, 2018/09/24 - 8:14am

Scientists demonstrate that a "gene drive" can rapidly spread a genetic mutation through a species, perhaps providing a potent new weapon against malaria. But there are plenty of skeptics.

New study reconciles a dispute about how fast global warming will happen | Dana Nuccitelli

Guardian Environment News - Mon, 2018/09/24 - 3:00am

Unfortunately, mainstream climate scientists are still right, and we’re running out of time to avoid dangerous global warming

We’re currently on pace to double the carbon dioxide-equivalent (including other greenhouse gases) in the atmosphere by around mid-century.  Since the late 1800s scientists have been trying to answer the question, how much global warming will that cause?

In 1979, top climate scientists led by Jule Charney published a report estimating that if we double the amount of carbon dioxide in the atmosphere from pre-industrial levels of 280 ppm to 560 ppm, temperatures will warm by 3 ± 1.5°C.  Four decades later, ‘climate sensitivity’ estimates remain virtually unchanged, but some climate contrarians have argued that the number is at the low end of that range, around 2°C or less.

'We're moving to higher ground': America's era of climate mass migration is here

Guardian Environment News - Mon, 2018/09/24 - 1:00am

By the end of this century, sea level rises alone could displace 13m people. Many states will have to grapple with hordes of residents seeking dry ground. But, as one expert says, ‘No state is unaffected by this’

After her house flooded for the third year in a row, Elizabeth Boineau was ready to flee. She packed her possessions into dozens of boxes, tried not to think of the mold and mildew-covered furniture and retreated to a second-floor condo that should be beyond the reach of pounding rains and swelling seas.

Boineau is leaving behind a handsome, early 20th-century house in Charleston, South Carolina, the shutters painted in the city’s eponymous shade of deep green. Last year, after Hurricane Irma introduced 8in of water into a home Boineau was still patching up from the last flood, local authorities agreed this historic slice of Charleston could be torn down.

the story of the cross

The Field Lab - Sun, 2018/09/23 - 3:28pm
When I was in the hospital with my broken leg, I had one nurse that became my favorite.  What I liked most about her was the fact that she had a small crocheted cross on her cart.  The two weeks I was there, we never spoke of our faith but I still found it to be a great comfort.  When I got home, I started working on casting a silver cross that I could give to her someday - this was my first attempt from years ago but I decided it was too small.  By the time I got it figured out, she had moved on to another hospital and I have yet to be able to track her down.

Opec predicts massive rise in oil production over next five years

Guardian Environment News - Sun, 2018/09/23 - 7:43am

Increasing demand from airlines will more than offset reductions from electric cars

World oil production will soar to new records over the next five years, as a dramatic expansion in demand from airlines offsets the arrival of electric cars, according to a report from Opec.

In a forecast that will dismay environmentalists – and which questions the theory that oil company reserves will become “stranded assets” – Opec’s annual report significantly revised production estimates upwards.
