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.

The forests you see today are not what you will see in the future. That’s the overarching finding from a new study on the resilience of Rocky Mountain forests, led by Colorado State University.

Researchers analyzed data from nearly 1,500 sites in five states — Colorado, Wyoming, Washington, Idaho, and Montana — and measured more than 63,000 seedlings after 52 wildfires that burned over the past three decades. They wanted to understand if and how changing climate over the last several decades affected post-fire tree regeneration, a key indicator of forest resilience.

The U.S. Naval Research Laboratory’s Marine Meteorology Division in Monterey, California, houses a team of scientists and engineers who work in conjunction with the lab’s broader scientific community to provide the fleet with the most accurate weather forecasts possible.
