Deforestation in the Amazon has been decreasing over the last 6 years, but it appears that the downward trend may have stopped, this year. Apart from deforestation, the Amazon rainforests are also reported to be sensitive to climate change. In turn, the forests play an important role in regulating climate, rainfall and South-American water supply.
NASA's new Aquarius instrument has produced its first global map of the salinity of the ocean surface, providing an early glimpse of the mission's anticipated discoveries. Aquarius, which is aboard the Aquarius/SAC-D (Satélite de Aplicaciones Científicas) observatory, is making NASA's first space observations of ocean surface salinity variations -- a key component of Earth's climate.
Relatively accurate predictions for summer sea ice extent in the Arctic can be made the previous autumn, but forecasting more than five years into the future requires understanding of the impact of climate trends on the ice pack.
Long-term observations indicate a positive trend in the quality of air in Lapland during the past 10-20 years. This favorable trend may be threatened by increased marine transport emissions from the Arctic Ocean, which may remain free of ice owing to climate change.
Researchers have found that periods of rapid fluctuation in temperature coincided with the emergence of the first distant relatives of human beings and the appearance and spread of stone tools.
Steep increase in global CO2 emissions despite reductions by industrialized countries with binding Kyoto targets
Global emissions of carbon dioxide -- the main cause of global warming -- increased by 45% between 1990 and 2010, and reached an all-time high of 33 billion tonnes in 2010.
During the 2010 Gulf oil spill, an estimated one of every 20 barrels of spilled oil was deliberately burned to reduce surface oil slick size and minimize impacts of oil on sensitive shoreline ecosystems and marine life.
Earth warming will presumably not lead to a permanent El Nino state in the South Pacific Ocean. This is the conclusion drawn by an international team of researchers after it investigated 50-million-year-old clam shells and wood from the Antarctic.
A shipboard expedition off Norway to determine how methane escapes from beneath the Arctic seabed has discovered widespread pockets of the gas and numerous channels that allow it to reach the seafloor.
Uncertain climate models impair long-term climate strategies: New calibration satellite required to make accurate predictions, say scientists
A new paper explains weaknesses in our understanding of climate change and how we can fix them. These issues mean predictions vary wildly about how quickly temperatures will rise, resulting in serious implications for long-term political and economic planning, experts argue.
