Among the Pueblo Indians of northern New Mexico, disease didn't break out until nearly a century after their first contact with Europeans, following the establishment of mission churches in the seventeenth century, a team of researchers has shown. The depopulation was so extreme it led to changes in forest fires in the region, they say.

Scientists have determined that the influx of fresh water from the Greenland ice sheet is 'freshening' the North Atlantic Ocean and could disrupt the Atlantic Meridional Overturning Circulation, an important component of global ocean circulation that could have a global effect. Researchers say the it could impact the future climate in places such as portions of Europe and North America.

The same geologic forces that stitched the supercontinent Pangea together also helped form the ancient coal beds that powered the Industrial Revolution, report researchers.

New research has quantified the change in regional extremes in a world where global average temperatures have risen by two degrees Celsius.

The Tibetan Plateau has long been seen as a “hotspot” for international environmental research, and there have been fears that water supplies in the major Asian rivers would drastically decline in the near future. However, new research now shows that water supplies will be stable and may even increase in the coming decades.

A new method is being applied to determine whether specific climate impacts can be traced to human-caused emissions. The past century has seen a 0.8°C (1.4°F) increase in average global temperature, and the overwhelming source of this increase has been emissions of greenhouse gases and other pollutants from human activities, they say.

A team of researchers has published their analysis of data, specimens, photographs and video footage collected in 2009, when they sent a remotely operated vehicle (ROV) to a depth of 800 meters (2,625 ft) at Osprey Reef off the far-northern coast of eastern Australia.

Early human agriculture cancelled natural cooling of Earth's climate, new ice core data and other evidence confirm. Earth naturally cycles between cool glacial periods and warmer interglacial periods because of variations in its orbit around the sun. We currently are in an interglacial period, called the Holocene epoch, which began nearly 12,000 years ago.
