The price has also been reduced to $7.99, a savings of 60% over the the hard copy list price. More than just a book about global warming, it is a tribute to nature and the scientists who study the Universe we live in. If you do not own a copy of this classic, now is the time to buy REP's all time best seller.
It has been vilified in the press and maligned in school classrooms by the ignorant. Opposing it has become a cause célèbre in Hollywood an a litmus test for liberal politicians. Labeled man's chosen weapon for ravaging nature and laying waste to the environment this poor, largely misunderstood gas is in fact essential to our existence. Without carbon dioxide, CO2, we would not be here and Earth would be a frozen lifeless chunk of rock. Forget that life would never have developed on a planet without greenhouse warming, a recent scientific study say the daemon gas has rescued the planet from the deep freeze at least twice during the Neoproterozoic era, roughly 750 to 635 million years ago.
Does fish fecal matter fight global warming by carrying organic carbon to the bottom of the ocean where it is sequestered in sediment? A new study claims that fish poo is under appreciated as a part of the natural carbon cycle and that it carries carbon to the ocean bottom much faster than dead zooplankton sink on their own. “Measurements of in situ abundance of fish fecal pellets or their flux are lacking, likely due to the difficulty of adequately sampling these particles,” the study's authors state, “to our knowledge, this is the first study to present estimates of fish fecal pellet abundance.” This study indicates that fish poo is an under appreciated component of both the carbon and nitrogen cycles. Surprisingly, waste from marine mammals, including whales, breaks up and degrades as it sinks, returning its carbon, nitrogen and other elements back to the environment.
The subject of human carbon dioxide emissions and their build up in Earth's atmosphere is at the center of the anthropogenic global warming controversy. It cannot be denied that humans produce CO2 in large amounts, both from burning fossil fuels and from land use changes. This has led to much gnashing of teeth and renting of garments by excitable ecological doomsayers, but there is something they do not mention: at the same time humanity is spewing forth carbon, nature is busily sucking up that carbon and storing it away. A new analysis of the carbon cycle has produced an unexpected result—not only is the absorption of carbon continuing unabated it has actually expanded. The latest scientific tally indicates that since 1959, approximately 350 billion tons of carbon have been emitted by humans to the atmosphere, of which about 55% has been reabsorbed by the land and oceans.
The IPCC is working up to releasing pieces of its next climate report, starting in 2013. This has the world's climate scientists scrambling to get their latest work included in that dubious document. Foremost among those struggling for primacy of place are the computer modelers, those who study their own created worlds instead of the natural one around them. This report promises to be more contentious than the last one (AR4) in that the modelers have been racing to incorporate the effects of aerosols, soot and other airborne particulates that had previously been give scant attention. Early results suggest that aerosols have a much greater impact on regional climate than scientists had realized and that aerosols and clouds are providing some big surprises.
Recently, the 3rd Nobel Laureate Symposium decided to hold a trial, charging humanity with ruining the planet. Based on the so called 9 Planetary Boundaries, a jury of 20 Nobel Laureates sat in judgment while “compelling evidence” was presented showing that “humanity may now be capable of radically altering the remarkable conditions for life on Earth.” The Planetary Boundaries approach was developed by 28 scientists, who estimated that three of the boundaries, climate change, the nitrogen cycle and biodiversity loss, have already been crossed and that several others are all ready in dangerous territory. We have all been charged with transgressing boundaries laid down by a group of scientists most people have never heard of, judged and found guilty by a gaggle of Nobel Prize winners, and been remanded to the UN for punishment. This sham trial does not represent justice but an attempt to place humanity in ecological bondage.
The ineffective and mostly ignored Kyoto agreement is due to expire in 2012. Climate change activists around the world are girding their loins in preparation for the battle over Kyoto 2, the follow on treaty. Their goal? New regulations for black carbon, methane and driving anthropogenic CO2 emissions to zero. Leaving no bad idea unused, there is talk of implementing a global cap & trade system where developed nations that are able to reduce emissions beyond their Kyoto targets can sell excess reduction credit to other developed nations through the Emissions Trading mechanism. Beyond that, rather than negotiating CO2 emission reduction targets on a nation-by-nation basis—as in the current Kyoto framework—a future level of maximum allowable global temperature increase can be chosen. It is clear that the warmists have made the transition from irrational to delusional.
Methane is an important greenhouse gas, 30 times more potent than CO2, but our knowledge of the methane cycle is woefully inadequate. Sediments on the ocean's floor contain immense quantities of methane and there are enormous fluxes of methane into and out of these sediments. Trapped frozen in ice, there are some 10,000 gigatons of carbon stored under the sea—twice as much carbon as contained in conventional fossil fuel reserves. Some scientists consider the release of this methane the single worst environmental danger we face as a species. A massive release of ocean floor methane could cause real runaway global warming that would have dramatic impact on life. But methane continually leaks from seabeds around the world, contributing to the total amount of carbon injected into the ecosystem. A new report finds that ocean methane concentrations have been underestimated by a factor of 10 to 20 fold.
Scientists believe that carbon released from the ocean floor played a key role in past episodes of climate change. Around 55 million years ago, the break-up of the northeast Atlantic continents was associated with the injection of large amounts of molten magma into seafloor sediments. Formation of the North Atlantic basalts heated the carbon-rich sediments, triggering the release of large quantities of methane and carbon dioxide into the ocean and atmosphere. It has been suggested that this release of previously sequestered carbon was responsible for a 100,000 year period of rapid temperature rise known as the Paleocene-Eocene Thermal Maximum or PETM. Three letters published in Nature Geoscience suggest that carbon trapped beneath the seabed continues to influence carbon dynamics, at least in the deep ocean.
The influence of the Sun on Earth’s climate over time scales of centuries and millennia is all but ignored by current climate change dogma, with many climate scientists dismissing solar variation as too feeble to have much of an impact. Though it was recently discovered that variation at ultraviolet wavelengths is considerably greater than at lower frequencies, the change in total solar irradiance over recent 11-year sunspot cycles amounts to <0.1%. New research on longer time scales finds the change in total irradiance sufficient to affect the dynamics of the El Niño–Southern Oscillation (ENSO). Detailed model studies of the Little Ice Age (~1400 to 1850 AD) conclude that the Sun controls an “ocean dynamical thermostat” that affects climate variability over large regions of the globe. It was also found that fully coupled general circulation models (GCMs), the kind used by the IPCC to make predictions of future global warming, lack a robust thermostat response. This means that the sensitivity of the climate system to solar forcing is underestimated by current GCMs—the climate models are proven wrong again.
Much has be written and even more said about stopping climate change. The total foolishness of such a quest is obvious to anyone with even the most cursory understanding of Earth's climate over the Past 65 million years. The more science learns about the ever changing nature of climate the more capricious nature appears and the less significant the labors of H. sapiens are revealed to be. To place the ludicrous arguments and unsubstantiated fears of climate catastrophists in perspective, it is instructive to survey Earth's climate since the demise of the dinosaurs—the geological time period called the Cenozoic Era. During this long span of time, Earth's climate has undergone a significant and complex evolution. If one truth has been discovered by human science it is that Earth's climate is always changing, driven, as one set of researchers put it, by trends, rhythms and aberrations—the mechanisms of climate change.
Climate scientists continue to be fascinated with the Paleocene–Eocene Thermal Maximum (PETM), which took place about 55 Myr ago. This period of sudden global warming and increasing atmospheric CO2 represents a possible model our present era of warming climate and growing CO2 emissions. Studying the PETM, therefore, may provide insight into climate system sensitivity and feedbacks. Just such a study, reported in Nature Geoscience, found that CO2 forcing alone was insufficient to explain the PETM warming. Scientists speculate that other processes and/or feedbacks, hitherto unknown, must have caused a substantial portion of the warming during the Paleocene–Eocene Thermal Maximum. Simply put, CO2 did not cause the PETM climate change.
Even though climate scientists have not been able to identify all of the factors involved in climate regulation, or even develop trustworthy values for the ones they do know about, some eco-activists are proposing that we actively try to alter Earth's climate. Schemes to purposefully alter the environment on a global scale are called geoengineering, and it has been proposed as a way to counter act anthropogenic global warming and its side effects. The two main geoengineering options are limiting incoming solar radiation, or modifying the carbon cycle. Two articles, one in the Proceedings of the National Academy of Science and another in Nature Geoscience, report that controlling climate through geoengineering would be difficult, if not impossible, and may do more harm than good. At a time when we cannot even predict how climate will change on its own, proposals to engineer climate change are best left as thought experiments.
It is well known that carbon dioxide cannot directly account for the observed increase in global temperature over the past century. This has led climate scientists to theorize that many feedback relationships exists within the climate system, serving to amplify the impact of rising CO2 levels. One of these is the impact of rising temperature on the ability of the ecosystem to absorb CO2. The temperature sensitivity of ecosystem respiratory processes (referred to as Q10) is a key determinant of the interaction between climate and the carbon cycle. New research, recently published in the journal Science, shows that the Q10 of ecosystem respiration is invariant with respect to mean annual temperature, and independent of the analyzed ecosystem type. This newly discovered temperature insensitivity suggests that climate sensitivity to CO2 is much smaller than assumed by climate models.
According to a new report in Nature Geoscience, scientists are beginning to realize that previously ignored aspects of the terrestrial biosphere can act as key regulators of atmospheric chemistry and climate. Not only that, changes in the biosphere can happen quickly—in the course of a few decades. “Although interactions between the carbon cycle and climate have been a central focus, other biogeochemical feedbacks could be as important in modulating future climate change,” states the report. Because a number of these feedbacks can have a cooling effect, the impact on global warming predictions could be earthshaking. The problem is, these feedbacks are only poorly understood and they are so interrelated that modeling them will be difficult, if not impossible.
