Disastrous Sea Level Rise Is an Issue for Today's Public -- Not Next Millennium's

sea level riseIn 2005, I argued that ice sheets may be more vulnerable than the Intergovernmental Panel on Climate Change (IPCC) estimated, mainly because of effects of a warming ocean in speeding ice melt. In 2007, I wrote "Scientific Reticence and Sea Level Rise," describing and documenting a phenomenon that pressures scientists to minimize the danger of imminent sea level rise.

About then I became acquainted with remarkable studies of geologist Paul Hearty. Hearty found strong evidence for sea level rise late in the Eemian to +6-9 m (20-30 feet) relative to today. The Eemian is the prior interglacial period (~120,000 years ago), which was slightly warmer than the present interglacial period (the Holocene) in which civilization developed. Hearty also found evidence for powerful storms in the North Atlantic near the end of the Eemian period.

Half of Columbia River sockeye salmon dying due to hot water

sockeye salmonMore than a quarter million sockeye salmon returning from the ocean to spawn are either dead or dying in the Columbia River and its tributaries due to warming water temperatures. Federal and state fisheries biologists say the warm water is lethal for the cold-water species and is wiping out at least half of this year's return of 500,000 fish.

"We had a really big migration of sockeye," said Ritchie Graves of the National Oceanic and Atmospheric Administration. "The thing that really hurts is we're going to lose a majority of those fish."

He said up to 80 percent of the population could ultimately perish.

On four continents, historic droughts wreak havoc

droughtCalifornia's historic drought appears to be matched by severe dry spells on three other continents. Brazil, North Korea and South Africa are bearing the brunt of much lower-than-average precipitation, wreaking havoc on millions of peoples' lives and livelihoods.

While the causes vary from country to country, the chance of more intense droughts in the future as a result of man-made climate change is only increasing as regional extremes of precipitation — both more and less — remain likely, according to the U.N.'s Intergovernmental Panel on Climate Change.

Fracking Linked to Heart Conditions and Neurological Illness

Fracking linked to heart and nerve illnessPeople who live in fracking zones appear to suffer a higher rate of heart conditions and neurological illnesses, according to new research.

Although the U.S. study was unable to determine a specific reason, it suggests there may be a link between drilling and ill health, scientists said.

Residents in high-density areas of fracking made 27 per cent more hospital visits for treatment for heart conditions than those from locations where no fracking took place, according to a new study of drilling in Pennsylvania between 2007 and 2011.

California communities mount protests against fracking, oil drilling

Californians protest against frackingMore than 100 children, parents and community organizers in fluorescent yellowish-green shirts and orange shoe covers marched through a South Los Angeles neighborhood earlier this week chanting, “Hey, hey, ho, ho, this drilling site has got to go!”

The canaries-in-a-coal-mine color-scheme of the protesters was intentional. There was even a giant cage in front of an oil drilling site on West Jefferson Boulevard that neighborhood children, most of them African American or Latino, crammed into, holding up signs asking to “Set these canaries free.”

Former Top NASA Scientist Predicts Catastrophic Rise In Sea Levels

Hansen predicts sea riseOne of the nation's most recognizable names in climate science, Dr. James Hansen, released a new paper this week warning that even 2 degrees Celsius of global warming may be "highly dangerous" for humanity.

The paper, which will be published online in the European Geosciences Union journal Atmospheric Chemistry and Physics Discussion later this week, projects sea levels rising as much as 10 feet in the next 50 years.

World mayors at Vatican seek 'bold climate agreement'

Mayors got to VaticanDozens of mayors from around the world demanded Tuesday that their national leaders take bold steps at the Paris climate talks later this year, saying that may be the last chance to keep the warming of the Earth at levels safe for humanity.

\Some mayors selected because they support Pope Francis' environmental message gathered Tuesday at the Vatican for a two-day conference to keep the pressure on world leaders ahead of the Paris negotiations in December. Francis last month released an environmental encyclical that denounced what he calls a fossil fuel-based world economy that exploits the poor and destroys the Earth.
