“It was once said that the flap of a butterfly’s wings in Brazil could set off a tornado in Texas, and our study provides new evidence of the remarkable interconnectedness of the world’s weather” – Robert Lee, University of Reading

Chris Colose is a NASA Climate expert working on a new global climate model (GCM). It’s called ROCKE-3D, and is designed to be used not only on earth but on extraterrestrial planets! I can show you could destroy civilization because Chris did it in the new GCM by taking out the CO2 and Methane in one of his model runs, but there’s something you should know first. Were you …

This from NOAA : The combined global land and ocean surface temperature departure from average for October 2019 was the second-highest for October in the 140-year record at 0.98°C (1.76°F) above the 20th century average 14.0°C (57.1°F). This value is just 0.06°C (0.11°F) shy of tying the record warm October set in 2015. The 10 warmest Octobers have occurred since 2003; however, the five warmest Octobers have all occurred since …

In a new study in the AGU journal Geophysical Research Letters, scientists found that in many areas of the U.S. springtime temperature thresholds important for plant and animal life cycles occur between six to 20 days earlier in the season than they did 70 years ago.

AGU’s global community of Earth and space scientists has contributed research and expertise to our understanding of—and solutions for—climate change, natural hazards, and their related impacts on people. Climate change, the increasing severity of extreme weather, and resulting floods are health and economic crises that we cannot ignore. To highlight the role that science plays to help address and mitigate issues such as flooding in communities across the United States, …

In the new study, researchers tested their hypothesis that a chain of events in the troposphere caused the sudden stratospheric warming and subsequent splitting of the polar vortex.

Every 4 years, AGU’s members have a chance to weigh in on position statements critical to maintaining the role of science in our society. Make sure your voice is heard. Starting today, 13 September 2019, AGU members will have 30 days to comment on revisions to two position statements: one on data and one on climate change. This open comment period is both an important opportunity for and responsibility of …

An increase in hotter, drier years in the coming decades due to climate change may worsen water scarcity issues in the Upper Nile Basin. These impacts are likely to cause an increase in agricultural failure in Ethiopia and may potentially lead to civil strife, according to the authors of a new study published in Earth’s Future, a journal of the American Geophysical Union.

A team of scientists has successfully teased out the influence of human-caused climate change on wintertime precipitation over much of the last century, showing that the warming climate is significantly altering wintertime rainfall and snowfall across the Northern Hemisphere.

A new study in AGU’s journal Geophysical Research Letters examined the region’s precipitation records from 1895 to 2018. The new research found precipitation in the Southeast during the fall increased by almost 40 percent in the past century due to an increase in average daily rainfall rather than the overall number of storms.

New research explores what conditions in the ocean and in the atmosphere prolong droughts in the Southwestern U.S. The answer is complex, according to a study published Aug. 6 in the Journal of Geophysical Research: Atmospheres, a journal of the American Geophysical Union.

New research in AGU’s Journal of Geophysical Research: Atmospheres finds chemicals used in pesticides that have been accumulating in glaciers and ice sheets around the world since the 1940s are being released as Himalayan glaciers melt as a result of climate change.

Nutrient deficiencies in rice grown under higher carbon dioxide could elevate health risks for tens of millions
A recent study in the AGU journal GeoHealth finds declines in B-vitamin concentrations in rice grown under elevated carbon dioxide concentrations may increase the future health risks of large numbers of people around the globe.

Icy planets once thought too cold to support life might have livable land areas above freezing, challenging the typical assumption of what kinds of planets might be habitable, a new study suggests.

Scientists Tackle Grand Challenges In the Earth and Space Sciences In New Special Centennial-Themed Collection
One hundred years ago when AGU was founded there were still large unmapped places on our planet and the idea of a person stepping on the moon was a dream. Discovery and wonder have characterized the last 100 years of science as we learned the plates shift, the climate changes, and scientists are studying the Moon, Mars, and beyond in detail. Our species now has a global view of how …

The amount of area burned across Africa declined by 18.5 percent between 2002 and 2016, according to a new study.

Isachsen, a permafrost monitoring site that sits at a latitude of 78 degrees north on the Arctic Canadian island of Ellef Ringnes, seemed like the last place that would feel the effects of climate change.

Scientists – as we explore and discuss #ShowYourStripes, let’s make sure we share this data visualization with our non-science networks and engage in some science communication
5 June 2019
An international team of researchers has combined demographic projections and climate scenarios across Africa for the first time. Rapid urbanization combined with climate change is having a major impact on the living conditions of city-dwellers in Africa, especially in terms of exposure to extreme – or even lethal – temperatures.

Over the last 40 years, Arctic sea ice thickness, extent and volume have declined dramatically. Now, a new study finds a link between declining sea ice coverage in parts of the Canadian Arctic and an increasing incidence of summer heat waves across the southern United States.
