All Global Warming
- 2013 was the fourth, sixth or seventh hottest year on record, say scientistsAccording to a report published by World Meteorological Organization (WMO), 2013 was the sixth warmest on record. But NASA and NOAA differ in their rankings.
- Volcanoes, trade winds may be behind 'pause' in global warmingA 12-year pause in global warming, after 20 years of rapidly rising surface temperatures, has scientists probing for the reason. Volcanic eruptions and undersea heat storage are emerging as likely explanations.
- Global warming: Ice loss makes Arctic itself a bigger climate changerAs the Arctic region loses ice cover to global warming, it is itself becoming a stronger contributor to warming than climate models had predicted it would, a new study finds.
- Penguins, even in Argentina, at risk from climate change, study saysPenguins in Punta Tombo, Argentina, have a new foe to contend with – global climate change. Heavy rains and high temperatures are endangering the world's largest breeding colony of Magellanic penguins.
- Are gassy cattle a bigger problem than US government thought?Cattle generate twice as much methane as the EPA supposed, according to a new report. The study's findings may also change assumptions about the safety of extracting natural gas, which consists primarily of methane.
- Global climate investment hits plateauGlobal climate financing hit $349 billion in 2012, just shy of the 2011 total, according to a new report. But the pause may be just a blip on the screen.
- UN panel: 'Extremely likely' that human activity behind most global warmingThe UN Intergovernmental Panel on Climate Change concludes that the past decade has been the warmest on record and, with medium confidence, that the last three decades are the warmest in 1,400 years.
- New climate change map adds a new factor: peopleA new map, published this week in Nature Climate Change, assesses the degree to which humans have modified regional landscapes, in addition to how exposed those regions already are to climate change.
- How global warming may lessen chance of another superstorm SandyGlobal warming could further lower the likelihood of the atmospheric conditions that last year shoved superstorm Sandy due west into New Jersey, a new study says. But stronger storms will worsen with global warming, the study found, and outweigh changes in steering currents predicted by the study's computer models.
- Environmental group wants to name hurricanes for global warming 'deniers'The environmental group 350.org has launched a new campaign called Climate Name Change that proposes a tongue-in-cheek revision to how hurricanes are named.
- Global warming, more wars? Climate could spark more conflict, study says.A 'metastudy' of 60 other studies suggests that there is a clear link between the climate and violence. Global warming raises the specter of more conflict, especially in Africa.
- New lake at North Pole? More of a pond, reallyIs the buzz warranted over a new "lake" at the North Pole thanks to global warming? Mostly no. But the Arctic ice is melting.
- Bloomberg details NYC plan to combat climate changeNew York City Mayor Michael Bloomberg laid out a multimillion dollar plan Tuesday to guard New York City against storms and the effects of global warming. Fueled by Superstorm Sandy last fall, the sweeping proposals for New York represent a sizeable step up in scale and urgency for Mayor Bloomberg.
- Atmospheric carbon dioxide levels reach milestoneA monitoring station in Hawaii has measured carbon dioxide levels of 400 parts per million, a concentration not seen on Earth since the Pleistocene Era.
- Earth's cooling came to sudden halt in 1900, study showsAn international study used tree rings and pollen to build the first record of global climate change, continent by continent, over 2,000 years.
- Antarctic ice tells conflicting story about climate change's role in big meltTwo different areas of Antarctica tell two very different stories about how climate change might be affecting ice melt. The data appear to confirm that climate change impacts can be very local.
- China temperature spikes linked to burning of fossil fuelsA new study from Chinese and Canadian researchers links the burning of fossil fuels to China's rise in its daily temperature spikes. China emits more greenhouse gas than the next two biggest carbon polluters – the US and India – combined.
- Fasten seatbelts, air passengers. Climate change ahead.Transatlantic flights will be bumpier by 2050 because of rising CO2 emissions, a new study finds. Turbulent episodes could double and the average strength of turbulence would also rise 10 to 40 percent.
- Global temperature rise is fastest in at least 11,000 years, study saysThe study, which also found the magnitude of the global temperature rise to be unmatched in 4,000 years, suggests that the current warming trend cannot be explained by naturally occurring temperature fluctuations.
- Global warming: Yet another threat to Southwest's iconic pinyon pine?Add to the long-studied global-warming perils of drought, insects, and wildfires, a new potential threat to the pinyon pine: dramatically lower production of seed-bearing cones.
