Extreme Weather And Climate Change Triggering National Security Threats

12 February, 2013


MessageToEagle.com - Some natural disasters are predictable but many others can occur with little or no warning at all.

As frequent extreme weather events such as droughts, floods, severe storms, and heat waves can strike quickly, scientists have focused the attention of climate scientists on the connections between greenhouse warming and extreme weather.

A new study was conducted to explore the forces driving extreme weather events and their impacts over the next decade, specifically because of the potential threat to U.S. national security.

The report finds that the early ramifications of climate extremes resulting from climate change are already upon us and will continue to be felt over the next decade, directly impacting U.S. national security interests.

"Lessons from the past are no longer of great value as a guide to the future," said co-lead author Michael McElroy, Gilbert Butler Professor of Environmental Studies at Harvard University. "Unexpected changes in regional weather are likely to define the new climate normal, and we are not prepared."

Changes in extremes include more record high temperatures; fewer but stronger tropical cyclones; wider areas of drought and increases in precipitation; increased climate variability; Arctic warming and attendant impacts; and continued sea level rise as greenhouse warming continues and even accelerates.

These changes will affect water and food availability, energy decisions, the design of critical infrastructure, use of the global commons such as the oceans and the Arctic region, and critical ecosystem resources.

They will affect both underdeveloped and industrialized countries with large costs in terms of economic and human security.

The study identifies specific regional climate impacts -- droughts and desertification in Mexico, Southwest Asia, and the Eastern Mediterranean, and increased flooding in South Asia -- that are of particular strategic importance to the United States.

The report concludes that the risks related to extreme weather require that the U.S. sustain and augment its scientific and technical capacity to observe key indicators, monitor unfolding events, and forewarn of impending security threats as nations adapt to a changing climate.

The study recommends a national strategy for strategic observations and monitoring -- including greenhouse gas and aerosol emissions, ocean temperatures, and satellite observations of the Arctic -- and improved forecast models.

"Our critical observational infrastructure is at risk from declining funding," added co-lead author D. James Baker, Director of the Global Carbon Measurement Program at the William J. Clinton Foundation and former Administrator of the National Oceanic and Atmospheric Administration (NOAA). "Without that knowledge, the needs of civil society and national security for mitigation and adaptation will go unmet."

Incredible Images Show Giant Sinkhole In Sweden Keeps Expanding!

It looks like something taken straight from a horror movie. An enormous hole leading to hell, some would say. But this is not a movie. This is a real and dangerous phenomenon. New shocking images clearly show the enormous pit in Sweden is expanding. The 200 foot wide open pit is called the "Fabiangropen" (Fabian pit) and is in the Malmberget area is located at Gällivare, 75km from Kiruna, Sweden.
