Global Warming 'Pause' Theory is Dead but Still Twitching

A study released Thursday is the second this year seeking to debunk a 1998-2013 "pause" in global warming, but other climate scientists insist the slowdown was real, even if not a game-changer.

When evidence of the apparent hiatus first emerged, it was seized upon by sceptics as evidence that climate change was driven more by natural cycles that humans pumping carbon dioxide into the atmosphere.

U.S. Scientists Make Tiny Invisibility Cloak

A tiny invisibility cloak has been invented by U.S. scientists who are edging ever-closer to a real version of what has until now been a staple of science fiction, researchers said Thursday.

The cloak, described in the journal Science, is microscopic in size but could conceivably be scaled up in the future, according to physicists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory and the University of California, Berkeley.

Air Pollution Kills 3.3 Million Worldwide, May Double

Air pollution is killing 3.3 million people a year worldwide, according to a new study that includes this surprise: Farming plays a large role in smog and soot deaths in industrial nations.

Scientists in Germany, Cyprus, Saudi Arabia and Harvard University calculated the most detailed estimates yet of the toll of air pollution, looking at what caused it. The study also projects that if trends don't change, the yearly death total will double to about 6.6 million a year by 2050.

Marine Populations 'Slashed by Half Since 1970'

Populations of marine mammals, birds, reptiles and fish have dropped by about half in the past four decades, with fish critical to human food suffering some of the greatest declines, WWF warned Wednesday.

In a new report, the conservation group cautioned that over-fishing, pollution and climate change had significantly shrunk the size of commercial fish stocks between 1970 and 2010.

U.S. Astronaut Misses Fresh Air Halfway through Year-long Mission

Halfway into a year in space -- the longest ever attempted at the International Space Station -- American astronaut Scott Kelly said Monday he misses fresh air but is adapting well.

Kelly and Russian cosmonaut Mikhail Kornienko agreed to double the length of a typical astronaut's mission at the ISS in order to help the world's space agencies study how long-term space travel affects the human body and mind.
