National Research Council: Prompt and Sustained Commitment Needed


U.S. NRC Panel Discusses Limiting Future Climate Change The principal conclusion of our report is that the country needs both a prompt and a sustained national commitment to reducing greenhouse gas emissions. – Robert W. Fri, Chair of the Panel on Limiting the Magnitude of Future Climate Change The National Academies of the United States … Continue reading

The Extreme Weather of 2010


Extreme Weather Events Felt Around the World in 2010 While no single weather event can be definitively traced to global climate change, we would expect to see a greater number of extreme weather events accompanying climatic shifts. As more water vapor enters the atmosphere with rising global temperatures, large-scale precipitation events become more commonplace resulting … Continue reading

National Research Council: Advancing the Science of Climate Change


This is not about a belief. This is about evidence. This is about observations. This is about an accumulated body of knowledge that tells us something about the way the world is working. We are having a huge footprint on the planet. – Dr. Pamela A. MatsonChair, The Panel on Advancing the Science of Climate … Continue reading

Environmental Headlines, Week of July 17, 2010

State of the Climate, Indicators of Change


As the United Nations Climate Change Conference in Copenhagen gets into full swing, it’s a good time to take a look around and assess the current state of things. In the 30 years of direct satellite observation… Solar irradiance has declined (Source: PMOD/WRC) which should drive temperatures down, and we are currently in the middle … Continue reading

Global Survey Visually Documents Glacial Retreat


The Extreme Ice Survey (EIS) is a coordinated effort to visually study and document rapidly changing glaciers around the world using time-lapse photography, conventional photography, and video. Sponsored in part by NASA, the National Science Foundation, and National Geographic, the EIS utilizes 27 cameras installed at 15 sites including Greenland, Iceland, Alaska, and the Rocky … Continue reading

World’s Poor Most Susceptible to Climate Change


Sustainability is predicated on predictability. How we build our homes, grow and find the food we eat, and locate the water we drink are all based on climatic consistency. Knowing how much rainfall to expect each year dictates crop selection, flood zones, drainage systems, and water reserves. Knowing what temperatures to expect dictates how we … Continue reading

National Science Academies Warn of Oceanic Acidifcation


Seventy National Science Academies from around the world have issued a joint statement today warning of increasing oceanic acidification in advance of a conference of governmental representatives from around the world in Bonn, Germany this week to discuss climate change. The Academies urged the participants to include acidification on the agenda for the governmental talks … Continue reading

Climate Scientists Meet in Copenhagen

Examining Earth’s Lungs


Several studies released this year and last have focused on the health of the world’s forests. Considered the Earth’s “lungs”, forests, both around the equator and away from it, are responsible for removing immense amounts of carbon dioxide from the atmosphere while returning oxygen to it. The studies have returned mixed results.
