When the carbon dioxide content of the atmosphere rises, the Earth not only heats up, but extreme weather events, such as lengthy droughts, heat waves, heavy rain and violent storms, may become more frequent. Whether these extreme climate events result in the release of more CO2 from terrestrial ecosystems and thus reinforce climate change has been one of the major unanswered questions in climate research. It has now been addressed by an international team of researchers working with Markus Reichstein, Director at the Max Planck Institute for Biogeochemistry in Jena. They have discovered that terrestrial ecosystems absorb approximately 11 billion tons less carbon dioxide every year as the result of the extreme climate events than they could if the events did not occur. That is equivalent to approximately a third of global CO2 emissions per year.
Brace yourself. You may not be able to tell yet, but according to global experts and the U.S. intelligence community, the earth is already shifting under you. Whether you know it or not, you’re on a new planet, a resource-shock world of a sort humanity has never before experienced.
Patzek is Professor and Chairman of the Petroleum and Geosystems Engineering Department at The University of Texas at Austin. He also holds the Cockrell Family Regents Chair #11. Between 1990 and 2008, he was a Professor of Geoengineering at the University of California, Berkeley. Prior to joining Berkeley, he was a researcher at Shell Development, a unique research company managed for 20 years by M. King Hubbert of the Hubbert peaks. In November 2012, Patzek became President of ASPO, the Association for the Study of Peak Oil.
Extreme energy will mean an extreme planet….All these processes have at least one thing in common: each pushes the envelope of what is technically possible in extracting oil (or natural gas) from geologically and geographically forbidding environments. They are all, that is, versions of “extreme energy.” To produce them, energy companies will have to drill in extreme temperatures or extreme weather, or use extreme pressures, or operate under extreme danger — or some combination of all of these. In each, accidents, mishaps, and setbacks are guaranteed to be more frequent and their consequences more serious than in conventional drilling operations. The apocalyptic poster child for these processes already played out in 2010 with BP’s Deepwater Horizon disaster in the Gulf of Mexico, and this summer we saw intimations of how it will happen again as a range of major unconventional drilling initiatives — all promising that “golden age” — ran into serious trouble.
In the past week the Arctic sea ice cover reached an all-time low, several weeks before previous records, several weeks before the end of the melting season. The long-term decline of Arctic sea ice has been incredibly fast, and at this point a sudden reversal of events doesn’t seem likely. The question no longer seems to be “will we see an ice-free Arctic?” but “how soon will we see it?”. By running the Arctic Sea Ice blog for the past three years I’ve learned much about the importance of Arctic sea ice. With the help of Kevin McKinney I’ve written the piece below, which is a summary of all the potential consequences of disappearing Arctic sea ice.
Epic floods, massive wildfires, drought and the deadliest tornado season in 60 years are ravaging the United States, with scientists warning that climate change will bring even more extreme weather.
Caution: It is vitally important not to make connections. When you see pictures of rubble like this week’s shots from Joplin, Mo., you should not wonder: Is this somehow related to the tornado outbreak three weeks ago in Tuscaloosa, Ala., or the enormous outbreak a couple of weeks before that (which, together, comprised the most active April for tornadoes in U.S. history). No, that doesn’t mean a thing.
