Random mutation, protein changes, tied start multicellular life
Posted by Washington Post: Juliet Eilperin on January 7th, 2016
ScienceDaily: All it took was one mutation more than 600 million years ago. With that random act, a new protein function was born that helped our single-celled ancestor transition into an organized multicellular organism. That's the scenario -- done with some molecular time travel -- that emerged from basic research in the lab of University of Oregon biochemist Ken Prehoda. The mutation and a change it brought in protein interactions are detailed in eLife, an open-access journal launched in 2012 with support...

Reuters: Fixing Flint, Michigan's lead-contaminated drinking water infrastructure could cost as much as $1.5 billion, the city's mayor said on Thursday after meeting with the governor to discuss the crisis, according to Detroit newspapers.
Flint Mayor Karen Weaver said in Lansing, the state capital, where she met with Governor Rick Snyder, that the cost to fix or replace the city's water pipes has been estimated in a range of millions of dollars to up to $1.5 billion, the Detroit News and Detroit Free...

Posted by Washington Post: Darryl Fears on January 7th, 2016
Washington Post: Last year’s wildfire season set a record with more than 10 million acres burned. That’s more land than Maryland, the District and Delaware combined.
More than half the total was the result of mega-fires in Alaska, where dryness due to historically low mountain snowpack and a freak lightning storm created perfect conditions for a huge blaze. The nation’s overall toll was about 4 million acres more than the yearly average, scorching a record set in 2006.
The record was anticipated by the U.S....

Washington Post: The developing world deserves reparations from wealthier nations as compensation for the harmful climate change effects that are mostly our fault. It’s us who have tainted our global commons by emitting vast amounts of carbon dioxide into the atmosphere, and us whose actions have led to extreme weather and other disasters in the world’s most vulnerable regions.
But a strictly financial mea culpa from rich nations won’t be enough. Rich countries should also invest in geoengineering projects to...

Posted by Washington Post: Juliet Eilperin on January 7th, 2016
ScienceDaily: How more than 1,000 tree species may occur in a small area of forest in Amazonia or Borneo is an unsolved mystery. Their ability to co-exist may depend on how trees get along with their neighbors. A new study based, in part, on data from the Smithsonian's Forest Global Earth Observatory (ForestGEO) network shows that trees worldwide compete in some of the same ways, making simpler models of forest response to climate change possible.
Published in Nature, the study demonstrated how 'personal' traits...

Posted by Washington Post: Juliet Eilperin on January 7th, 2016
Climate Central: TransCanada is suing the U.S. government for more than $15 billion in losses and damages for denying the Canadian company's permit to build the Keystone XL Pipeline.
The U.S. State Department denied the permit in November, saying that the proposed $8 billion pipeline would undermine U.S. global leadership on climate change. Keystone XL would have transported more than 800,000 barrels of crude oil each day from the Canadian tar sands in Alberta to oil refineries in Texas.

December in US was warmest, wettest on record
Posted by Agence France-Presse: Kerry Sheridan on January 7th, 2016
Agence France-Presse: Wet weather and scorching temperatures propelled the United States into record books for the hottest December in modern history and the second warmest year since the late 1800s, US government scientists said Thursday. The report from the National Oceanic and Atmospheric Administration is the latest to document a warming trend that many scientists expect will make 2015 the planet's steamiest year on record. Man-made climate change resulting from the burning of fossil fuels, along with the El Nino...
El Niño rains get L.A. River roaring to life
Posted by LA Times: Joe Mozingo on January 7th, 2016
LA Times: At the end of Wood Avenue in South Gate, unseen behind its levee, the ephemeral giant strained in its cage.
The raw power drew Rita Adams for the first time in her 40 years of living in the neighborhood. She and her son walked under bare winter elms, past tidy postwar homes with American flags flapping in the rain, up the sandy embankment of an old Union Pacific track, to the top of the concrete channel.
She lit a cigarette and shook her head. "Wow."
The Los Angeles River had awakened. ...
Africa takes fresh look at GMO crops as drought blights continent
Posted by Washington Post: Juliet Eilperin on January 7th, 2016
Reuters: A scorching drought in Southern Africa that led to widespread crop failure could nudge African nations to finally embrace genetically modified (GM) crops to improve harvests and reduce grain imports.
The drought, which extends to South Africa, the continent's biggest maize producer, has been exacerbated by an El Nino weather pattern and follows dry spells last year that affected countries from Zimbabwe to Malawi.
Aid agency Oxfam has said 10 million people, mostly in Africa, face hunger because...

Posted by CBC: None Given on January 7th, 2016
CBC: New research suggests farms in developed countries may be more vulnerable to longer, deeper droughts predicted to occur as a result of climate change. "(Those farms) are really good in terms of producing high yields in stable climates, but maybe they're more vulnerable to weather shocks," said Navin Ramankutty of the University of British Columbia, co-author of a paper published Wednesday in the journal Nature. Ramankutty and his colleagues examined United Nations crop data from 177 countries between...
