Global warming pollution increases 3 percent - Associated Press
World pollution of CO2 jumped 3 per cent from 2006 to 2007. That exceeds the most dire outlook for emissions projected by the IPCC. Meanwhile, forests and oceans, which suck up carbon dioxide, are doing so at lower rates. If those trends continue, the world is on track for the highest predicted rises in temperature and sea levels - that is 10C and 85 meters!.
Einstein fridge design can help global cooling – Guardian
Scientists relaunch a 1930 invention that uses no electricity and would reduce greenhouse gases. An early invention by Albert Einstein has been rebuilt by scientists at Oxford University who are trying to develop an environmentally friendly refrigerator that runs without electricity. Modern fridges are notoriously damaging to the environment – a three-year project to develop more robust appliances that can be used in places without electricity.
Has runaway climate change begun? – Independent
The first evidence that millions of tons of methane is being released into the atmosphere from beneath the Arctic seabed has been discovered. Massive deposits of sub-sea methane are bubbling to the surface as the Arctic region becomes warmer and its ice retreats. The sudden release of methane in the past has been responsible for rapid increases in global temperatures, dramatic changes to the climate, and the mass extinction of species.
Earth Overshoot Day 2008 - Global Footprint network
September 23 this year marks the day humanity will have used all the resources nature will generate this year, when we begin to live beyond our ecological means for the rest of this year. For the rest of the year we move into the ecological equivalent of deficit spending, utilizing resources at a rate faster than what the planet can regenerate. We now require the equivalent of 1.4 planets to support our lifestyles. Having only one Earth our supply of natural resources -- like trees and fish -- continues to shrink, while our waste, primarily carbon dioxide, accumulates.
Global Warming's Ecosystem Double Whammy - Science News
Plants and soils act like sponges for atmospheric carbon dioxide, but new research finds that one abnormally warm year can suppress the amount of carbon dioxide taken up by some grassland ecosystems for up to two years. The findings follow an unprecedented four-year study to quantitatively track the response in carbon dioxide uptake and loss in entire ecosystems during anomalously warm years. The 'lagged' responses that carry over for more than one year are a dramatic reminder of the fragility of ecosystems that are key players in global carbon sequestration.
NASA Study Illustrates How Global Peak Oil Could Impact Climate
The burning of fossil fuels — notably coal, oil and gas — has accounted for about 80% of the rise of C02 since the pre-industrial era. Pushker Kharecha and James Hansen of NASA's Goddard Institute for Space Studies have identified feasible emission scenarios that could keep C02 below levels that are dangerous for climate. They considered a wide range of fossil fuel consumption scenarios. The research shows that the rise can be kept below harmful levels as long as emissions from coal are phased out globally within the next few decades.
So there is hope if, IF, IF …….
The State of U.S. Geothermal Production and Development - Leslie Blodgett
Geothermal energy is considered the best form of renewable energy for its ability to provide continuous, 24-hour, clean, sustainable energy production. With 3K megawatts installed the US is the world leader with 30% of the online capacity total. A recent industry update showed an increase in the pace of geothermal production in the U.S while new technologies promise increased growth in locations previously not considered in using the heat of the Earth itself for substantial and widespread energy production.
Isle of plenty – Guardian
Ten years ago, Samsinger island in Denmark drew nearly all their energy from oil and petrol brought in by tankers and from coal-powered electricity transmitted to the island through a mainland cable link. Today that traffic in energy has been reversed. They now export millions of kilowatt hours of electricity from renewable energy sources to the rest of Denmark. In doing so, islanders have cut their carbon footprint by a staggering 140%. And what Samsingers can do today, the rest of the world can achieve in the near future, it is claimed.
