Whenever a skeptic points out a new paper or journal article refuting some claim made by the theory of anthropogenic global warming, climate change alarmists often shout “cherry picking!” Evidently, most climate change true believers do not understand how science works or how theories are tested. Scientific theories must make predictions by which they can be tested. Providing evidence that AGW has failed in its predictions is not cherry picking, it is refutation. Unfortunately, when confronted with failed predictions the standard alarmist answer is to disavow the predictions. They will say that those are not predictions at all, they are projections—and that means AGW is not a scientific theory at all.
According to the AP, top researchers now agree that the world is likely to get stronger but fewer hurricanes in the future because of global warming, seeming to settle a scientific debate on the subject. But they say there's not enough evidence yet to tell whether that effect has already begun. Despite warnings by scientists that identifying an actual trend in storm variability is impossible due to a lack of reliable historical data, a new report in Nature Geoscience is being cited as a solid prediction of future trends in tropical cyclone activity. The other thing not mentioned is that this research is based on models of questionable accuracy.
With CO2 driven global warming becoming more discredited by new scientific evidence every day, the world's meddling climate regulators are casting about for a new gas to demonize. Last year the US Environmental Protection Agency was reportedly thinking of even classifying water vapor as a pollutant, due to its central role in global warming. Because water vapor is the dominant greenhouse gas in the atmosphere, accounting for the majority of the Earth's natural greenhouse effect, water vapor emissions during human activities—such as the processing and burning of fossil fuels—are again coming under increasing scrutiny by government regulators.
Around 1.2 million years ago, only 18,500 early humans were breeding on the planet. According to researchers, this is evidence that there was a real risk of extinction for our early ancestors. What's more, according to a new study it took at least a million years for humans to come back from the brink. It was not until the emergence of modern humans, Homo sapiens, around 160,000 years ago and their migration out of Africa that humanity's place on Earth was secured. Two factors helped humans to survive: an increasingly carnivorous diet and mastery of fire.
A new round of pro-global warming papers have begun to appear as the vested interests of the climate change community attempt to resuscitate their failed theory. Having been exposed as a theory full of holes, based on uncertain, perhaps even corrupt, data and overly dependent on computer modeling for “proof,” the supporters of catastrophic climate change are trying to rally. Amid mounting attacks on the IPCC, a small number of its leaders are trying to explain themselves to colleagues, the press and the people of the world. Now that their highhanded, tolerate-no-dissent approach has failed, it seems some IPCC scientists are open to compromise.
A surprising revelation from a new paper: industrial emission actually have a net cooling effect on Earth's climate. The paper that appears in the Proceeding of the National Academy of Sciences early edition attempts to apportion blame for global warming among various economic sectors. Climate impacts of CO2, tropospheric ozone, fine aerosols, aerosol-cloud interactions, methane, and long-lived greenhouse gases were all analyzed and the appropriate human activities cited. When the dust settled, two sectors turned in large net negative (i.e. cooling) forcing values: biomass burning and industry.
The debate over anthropogenic global warming—a theory propounded by the UN IPCC—is often portrayed as an argument between deniers and true believers. The deniers supposedly claim that there is no global warming, man made or otherwise, and that the whole theory is a plot by left-wing agitators and closet socialists bent on world domination. The true believers, conversely, accept every claim of pending future disaster uttered by scientists and activists alike. As with most controversies both extreme positions are wrong and the truth lies somewhere in-between. As a scientist, I have studied the evidence and find the case for imminent, dangerous, human caused global warming unconvincing—here is why I am an AGW skeptic.
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?
