WASHINGTON — Global warming is making the world’s oceans sicker, depleting them of oxygen and harming delicate coral reefs more often, two studies show.
The lower oxygen levels are making marine life far more vulnerable, the researchers said. Oxygen is crucial for nearly all life in the oceans, except for a few microbes.
WASHINGTON — The term bomb cyclone sounds scary, but it’s a real weather term and it fits the storm that sprang up from the U.S. Southeast.
WASHINGTON — Summer thunderstorms in North America will likely be larger, wetter and more frequent in a warmer world, dumping 80 per cent more rain in some areas and worsening flooding, a new study says.
Future storms will also be wilder, soaking entire cities and huge portions of states, according to a federally-funded study released Monday in the journal Nature Climate Change.
WASHINGTON — Scientists say global carbon pollution went up this year after three straight years when it didn’t go up at all.
Preliminary figures project that worldwide carbon dioxide emissions rose about 2 per cent. The heat-trapping gas is a key cause of global warming.
The report out Monday dashes hopes that emissions from the burning of coal, oil and gas had peaked.
WASHINGTON — The ozone hole over Antarctica shrank to its smallest peak since 1988, NASA said Thursday.
The huge hole in Earth’s protective ozone layer reached its maximum this year in September, and this year NASA said it was 7.6 million square miles wide (19.6 million square kilometres). The hole size shrinks after mid-September.
WASHINGTON — Global warming is hurting people’s health a bit more than previously thought, but there’s hope that the Earth ‚Äî and populations ‚Äî can heal if the planet kicks its coal habit, a group of doctors and other experts said.
WASHINGTON — Monarch butterflies, those delicate symbols of spring and summer, should mostly be in Texas by now, winging their way to Mexico for the winter.

WASHINGTON — It was a faint signal, but it told of one of the most violent acts in the universe, and it would soon reveal secrets of the cosmos, including how gold was created.
Astronomers around the world reacted to the signal quickly, focusing telescopes located on every continent and even in orbit to a distant spot in the sky.
WASHINGTON — When two extremely dense neutron stars crashed together in a distant galaxy, astronomers struck scientific gold, confirming previously unproven theories, including some from Albert Einstein.
