A developing area of tropical low pressure designated System 96W was affecting the central Philippines when NASA-NOAA’s Suomi NPP satellite passed overhead.

Approaching the second half of the century, the United States is likely to experience increases in the number of days with extreme heat, the frequency and duration of heat waves, and the length of the growing season. In response, it is anticipated that societal, agricultural and ecological needs will increase the demand on already-strained natural resources like water and energy. University of Illinois researchers have developed new, high-resolution climate models that may help policymakers mitigate these effects at a local level.

The oldest ice core ever drilled outside the polar regions may contain ice that formed during the Stone Age—more than 600,000 years ago, long before modern humans appeared.

Researchers from the United States and China are now studying the core—nearly as long as the Empire State Building is tall—to assemble one of the longest-ever records of Earth’s climate history.

What they’ve found so far provides dramatic evidence of a recent and rapid temperature rise at some of the highest, coldest mountain peaks in the world.

New research shows human-induced climate change increased the amount and intensity of Hurricane Harvey’s unprecedented rainfall. The new findings are being published in two separate studies and being presented in a press conference today at the 2017 American Geophysical Union Fall Meeting, along with additional new findings about recent Atlantic Ocean hurricanes.

It may take until the 2060s to know how much the sea level will rise by the end of this century, according to a new Rutgers University–New Brunswick-led analysis. The study is the first to link global and local sea-level rise projections with simulations of two major mechanisms by which climate change can affect the vast Antarctic ice sheet.

A NOAA-sponsored report shows that the warming trend transforming the Arctic persisted in 2017, resulting in the second warmest air temperatures, above average ocean temperatures, loss of sea ice, and a range of human, ocean and ecosystem effects.

Now in its 12th year, the Arctic Report Card, released today at the annual American Geophysical Union fall meeting in New Orleans, is a peer-reviewed report that brings together the work of 85 scientists from 12 nations.

To help untangle fact from speculation, Cornell climate scientists and their colleagues have developed a “robust null hypothesis” to assess the odds of a megadrought – one that lasts more than 30 years – occurring in the western and southwestern United States. The research was published online Dec. 8 in the Journal of Climate.

Maps of the world’s most important wilderness areas are now freely available online following a University of Queensland and Wildlife Conservation Society-led study published today.

NASA analyzed the rainfall generated by short-lived Tropical Cyclone 04B that formed and faded over a day in the Bay of Bengal.

A new study from the Energy Department’s National Renewable Energy Laboratory (NREL) establishes a novel catalytic method to produce renewable acrylonitrile using 3-hydroxypropionic acid (3-HP), which can be biologically produced from sugars. This hybrid biological-catalytic process offers an alternative to the conventional petrochemical production method and achieves unprecedented acrylonitrile yields.
