Ocean acidification threatens entire marine food chains

Not all of the CO2 emitted by human industrial activities remains in the atmosphere. Between 25% and 50% of these emissions over the industrial period have been absorbed by the world’s oceans, preventing atmospheric CO2 buildup from being much, much worse. But this atmospheric benefit comes at a considerable price. As ocean waters absorb CO2 … Continue reading

Global Cooling? Pick a Time, Any Time.

Satellite Record Now Shows Warming Across All Date Ranges I don’t think that anyone disagrees with the fact that we actually are in the middle of a cold period that started about nine years ago. Now that’s not me talking. Those are the scientists who say that. – U.S. Senator James Inhofe, July 23, 2010 … Continue reading

Prof. Stephen H. Schneider (1945-2010)

The scientific community lost one of its great voices this week when Stephen Schneider, Professor of Environmental Biology and Global Change at Stanford University, passed away from a sudden heart attack. Dr. Schneider was an early voice, warning of the dangers of escalating carbon emissions to the global environment, and his contributions to science and … Continue reading

Environmental Headlines, Week of July 17, 2010

The continued impacts and actions revolving around the BP oil spill continued to command the majority of headlines this week with BP becoming cautiously optimistic after finally capping the leak that has spilled tens of millions of gallons of oil over the last 4 1/2 months since its Deepwater Horizon rig exploded in the Gulf … Continue reading

Physics Society Quietly Reaffirms Climate Change Policy Stance

American Physical Society Reaffirms That Human Activities Affect Earth’s Climate. There is a substantial body of peer reviewed scientific research to support the technical aspects of the 2007 APS statement….Greenhouse gas emissions are changing the Earth’s energy balance on a planetary scale in ways that affect the climate over long periods of time (~100 years)….While … Continue reading

Did You Know? – Changes in Oceanic Acidity

Global ocean surface waters have become 30% more acidic since the start of the Industrial Revolution

Did You Know? – Thickness of Earth’s Atmosphere

Proportionally, the Earth’s atmosphere is no thicker than the skin of an apple.

Did You Know? – Non-Greenhouse Gases in the Atmosphere

Nitrogen (78%) and oxygen (21%) which comprise over 99% of the dry atmosphere, are not greenhouse gases and do not contribute to the Earth’s greenhouse effect.

Did You Know? – Average Minimum Temperature on Mercury

With no greenhouse effect to moderate its climate, the average minimum temperature on Mercury, the planet closest to the Sun, is -280 deg Fahrenheit.

Did You Know? – Earth Temperature Without Greenhouse Effect

Without a greenhouse effect, the average temperature on Earth would be 0 deg Fahrenheit.
