How You Can Destroy Civilization and Virtually No One Would Notice- At Least For a Few Days!

  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 …

NOAA: October 2019 Was 2nd hottest. 5 Hottest Octobers All since 2013.

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 …

Advancing spring warmth could disrupt species migration, development

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 Releases Report to Address Flooding in Communities

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, …

AGU Position Statements Now Open for Member Comment

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 …

Upper Nile will experience more water scarcity due to hotter, drier periods

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.

Climate change is altering winter precipitation across the Northern Hemisphere

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.

More intense non-tropical storms causing increased rainfall in Southeast U.S.

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.

Decades-old pollutants melting out of Himalayan glaciers

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.

Study suggests frozen Earthlike planets could support life

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 …

One third of the African urban population exposed to extreme heat by 2090

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.

Loss of Arctic sea ice stokes summer heat waves in southern U.S.

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.
