Study Finds Earth's Ocean Abyss Has Not Warmed

Source - NASA Science News for October 6, 2014

The cold waters of Earth's deep ocean have not warmed measurably since 2005, according to a new NASA study, leaving unsolved the mystery of why global warming appears to have slowed in recent years.

Arctic Melt Season Lengthens

Source - NASA Science News for April 1, 2014

A new study shows that the length of the melt season for Arctic sea ice is growing by several days each decade. This is allowing the Arctic Ocean to absorb enough additional solar radiation in some places to melt as much as four feet of the Arctic ice cap's thickness.

Industrial Soot Linked to the Retreat of 19th Century Glaciers

NASA Science News for Sept. 4, 2013

Researchers have uncovered strong evidence that soot from a rapidly industrializing Europe caused the abrupt retreat of mountain glaciers in the European Alps that began in the 1860s, a period often thought of as the end of the Little Ice Age.

Big Picture Science for 05/20/13 - Skeptic Check: Hostile Climate

Big Picture Science - Skeptic Check: Hostile Climate

It’s a record we didn’t want to break. The carbon dioxide concentration in the atmosphere has hit the 400 parts-per-million mark, a level at which some scientists say is a point of no return for stopping climate change. A few days later, a leading newspaper prints an op-ed essay that claims CO₂ is getting a bad rap: it’s actually good for the planet. The more the better.

Skeptic Phil Plait rebuts the CO₂-is-awesome idea while a paleontologist paints a picture of what Earth was like when the notorious gas last ruled the planet. Note: humans weren’t around.

Plus, our skit says NO to O₂ … and a claim that climate change skeptics have borrowed from the Creationists’ playbook in challenging the teaching of established science in schools.

Guests:

• Phil Plait – Astronomer, Skeptic, and author of Slate Magazine’s blog Bad Astronomy
• Peter Ward – Paleontologist and biologist, Department of Earth and Space Sciences, University of Washington in Seattle
• Josh Rosenau – Programs and Policy Director at the National Center for Science Education

NASA Finds 2012 Sustained Long-Term Climate Warming Trend

Source - NASA Science News for Jan. 15, 2013

NASA scientists say 2012 was the ninth warmest of any year since 1880, continuing a long-term trend of rising global temperatures. With the exception of 1998, the nine warmest years in the 132-year record all have occurred since 2000, with 2010 and 2005 ranking as the hottest years on record.

Are We Alone for 03/08/10 - Skeptic Check: Climate Clamor

Are We Alone - Skeptic Check: Climate Clamor

Arctic ice is melting, atmospheric temperatures are climbing – yet climate change science is under attack. Detractors claim that researchers are manipulating data and hoodwinking the public. And the public is increasingly skeptical about the science.

Find out what’s behind the surge of climate change skepticism… what the IPCC really does… and why snowstorms don’t refute global warming.

Plus a health report on the world’s coral reefs and what we’ll miss if they disappear.

It’s Skeptic Check… but don’t take our word for it!

Guests:

• Stephen Schneider – Climate scientist, Stanford University
• Phil Chapman – Apollo 14 Mission Scientist, now a geophysicist and consultant on energy and astronautics
• Simon Donner – Geographer at the University of British Columbia
