Forests and their soils are one of our planet's major sinks of biologically active carbon and contain the majority of Earth’s terrestrial carbon stock. Some climate change alarmists have said that the world's forest are in danger from the effects of climate change. Recent studies have shown increases in plant growth across many forest types. Now, a new paper in the Proceedings of the National Academy of Sciences reports that the increase in forest biomass is due to rising CO2 levels and warmer weather—in other words, trees love global warming whether human caused or natural.
A 2009 editorial in the journal Nature Geoscience, opined that, if participants at the Copenhagen Climate Conference failed to map out a path for future greenhouse-gas emissions that is both effective and feasible, then humanity might have to consider turning to “geoengineering.” Geoengineering, a term unfamiliar to most, is the deliberate manipulation of Earth's climate system to control global warming. Since Copenhagen was a resounding flop, new geoengineering proposals have been springing up in a number of scientific journals. Science is still struggling to understand how climate works and what accidental impacts human activities have on that system. Now a number of “visionaries” want to mess with the planet on purpose—what could possibly go wrong with that?
A new report in Science underscores what many scientists have been saying for years, it's water vapor, not CO2, that has been driving global temperature changes in recent decades. Stratospheric water vapor concentrations decreased by about 10% after the year 2000, slowing the rate of global surface temperature increase over the past 10 years. It also seems likely that water vapor in the stratosphere increased between 1980 and 2000, causing surface temperatures to warm by an extra 30% during the 1990s. These findings show that stratospheric water vapor represents an important driver of decadal global surface climate change, yet the IPCC crowd continues to focus on CO2.
Like a star footballer headed for the goal, Rajendra Pachauri, the head of the Intergovernmental Panel on Climate Change (IPCC), has seemingly been rushing toward his own dismissal. After a report debunking IPCC claims that Himalayan glaciers were melting faster than other glaciers and that they would be fully melted by 2035, Pachauri termed the research “voodoo science” and accused the Indian environment ministry of “arrogance” for its report. As it turns out, it was the IPCC's claims that were bogus, based on third hand speculation from a little known scientist.
With all the predictions of short term climate catastrophes proffered by global warming alarmists it is hard to look forward to a future time on Earth. What does the future hold a thousand, ten thousand, a million years from now? Science has some predictions about that as well, though the news media have not picked up on them. What environmental changes await us on the long road ahead?
One well accepted definition of the “Three Pillars of Science” lists the three as theory, experimentation and computation. For climate science this translates into climate theory, gathering climate data, and climate modeling. The three pillars are due an update in this post Copenhagen, post Climategate world. After reviewing the past year's crop of discoveries and disclosures, it seems that all three pillars are still wobbly at best—even without questionable conduct on the part of warm-mongering researchers.
On January 12, a series of earthquakes measuring 6.5 to 7.3 on the Richter scale struck the Caribbean nation of Haiti. Following the massive earthquakes, the island nation of 9.8 million people is in desperate need of help. The staff of The Resilient Earth would like to ask all of our readers to help relieve the suffering of the people of Haiti by making a donation to their local Red Cross, Red Crescent or other charitable organization involved in the emergency aid effort. This has nothing to do with science, global warming or politics, but it has everything to do with being citizens of this planet.
There have been a number of strange theories regarding the conditions deep within Earth's interior circulating around the internet. Claims that solar flares will cause nuclear reactions deep below our feet are perhaps the most ludicrous, but fairly easy to dismiss. More timely, perhaps, is the sudden conversion of global warming guru Al Gore into a geothermal energy booster. Evidently Gore thinks it's bad to drill for oil, but good to drill for heat. TV documentaries threaten mega-volcano eruptions and talk about mantle plumes underneath Hawaii, but just what does science tell us about our planet's interior?
Of all the ludicrous, wrong headed and down right stupid things to come out of the Copenhagen Climate Conference perhaps the most annoying was the formation of an ad hoc anti-nuclear umbrella organization. Over a dozen NGOs participating in the international “Don’t Nuke the Climate” campaign presented government delegates with a giant postcard and 50,000 signatures calling for a nuclear free climate agreement. There are ~6.5 billion people on Earth so the collected signatures amount to 0.000769 percent of the global population. Where do the rest of us sign up for a dingbat free planet?
A number of recent papers analyzing the nature of climate models have yielded a stunning result little known outside of mathematical circles—climate models like the ones relied on by the IPCC contain “irreducible imprecision.” According to one researcher, all interesting solutions for atmospheric and oceanic simulation (AOS) models are chaotic, hence almost certainly structurally unstable. Further more, this instability is an intrinsic mathematical property of the models which can not be eliminated. Analysis suggests that models should only be used to study processes and phenomena, not for precise comparisons with nature.
In an essay adapted from his 2009 AAAS Annual Meeting keynote address, James J. McCarthy has produced a fairly concise statement of the anthropogenic global warming believer's world view. After a self-serving review of climate science history, McCarthy trots out the usual litany of climate change troubles: increased cyclones, rain and floods, rising sea levels and, of course, those pesky tipping points. The tone of the article is set early on, when research is cited stating that mankind's impact on Earth is “sufficiently profound to declare that we have transitioned from the Holocene era of Earth history to the Anthropocene.”
Another trip around the Sun and the resilient Earth endures, as it has for the past 4.5 billion years. We here at The Resilient Earth would like to wish everyone on the planet and especially our loyal readers a very Happy New Year, 2010.
There is another contender in the alternate energy, renewable fuels sweepstakes that combines aspects of solar energy and biofuels. Most solar technologies are aimed at producing electricity, but a new class of solar chemical reactors aims to make liquid fuels from air, water, and sunshine. This could, in theory, provide a carbon neutral replacement for liquid fossil fuels. The catch? The process is costly and unlikely ever to compete with gasoline produced from fossil fuels without a punishing tax on carbon emissions.
Once again the leaders in the fight against anthropogenic global warming have come together to hold an international fear fest, supposedly to save mankind from the ravages of climate change—or to save the planet from mankind, depending on who you talk to. The predictable result: more strident warnings of disaster, pledges of more far reaching actions from politicians, and no real change. After jetting into Denmark, expending the carbon equivalent of more than 200,000 trees, the carping climate crowd has jetted back home until the next act of this farce takes place in Mexico City in 2010.
While climate skeptics have gleefully pointed to the past decade's lack of temperature rise as proof that global warming is not happening as predicted, climate change activists have claimed that this is just “cherry picking” the data. They point to their complex and error prone general circulation models that, after significant re-factoring, are now predicting a stretch of stable temperatures followed by a resurgent global warming onslaught. In a recent paper, a new type of model, based on a test for structural breaks in surface temperature time series, is used to investigate two common claims about global warming. This statistical model predicts no temperature rise until 2050 but the more interesting prediction is what happens between 2050 and 2100.
