Things have settled down a bit since the climate research scandals of early 2010, and some of the crew at the Met Office Hadley Centre have put forth a new paper. In it they claim the ability to “skillfully” predict hurricane activity for several years in advance. This seems a useful and more reasonable thing for this bunch to be doing, as opposed to scaremongering about anthropogenic global warming, but there is a catch. As it turns out, the whole exercise is aimed at blaming a purported increase in hurricane activity on global warming—the climate change scam lives on.
With the American mid-term elections finally over, the deafening din of political propaganda and news punditry has dropped to a dull roar. Having admitted that there were no “shovel ready” jobs in the offing, and that taking a “shellacking” is no fun, Barack Obama has nonetheless continued to talk up the idea of “green jobs.” This flies in the face of both reason and experience. To date, green job creation has been a resounding failure. American intellectuals and left leaning politicians have pointed out that Europe is a decade ahead of the US in embracing the new green economy. Since this White House seems infatuated with all things European, here is a lesson they can borrow from the old continent: creating artificial green jobs is bad for a nation's economy.
After all the fanfare a few months back, when US President Obama announced government loan guaranties for a new nuclear power plant in Georgia, the truth is emerging—Obama is quietly letting the nuclear Renaissance die from neglect and broken promises. Trying to distract green critics and the public with its approval of plans to build the world's biggest solar-thermal power plant in the Southern California, the administration ignored the faltering plans to expand an existing power plant on the Chesapeake Bay. Constellation Energy sent a letter to the US DOE stating that the terms offered by the government to guaranty financing for expanding the Calvert Cliffs nuclear power plant were “unworkable” and that the project could not go forward. Despite paying lip service to reviving nuclear power by providing government backed loans, the extreme greens in the Obama administration are trying to kill the nuclear power industry.
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.
While governments invest heavily in wind power something has been happening to the surface winds of the Northern Hemisphere—the winds have been slowing down. While the cause of this “stilling” remain uncertain, surface winds have declined in China, the Netherlands, the Czech Republic, the United States and Australia over the past few decades. A new study, published online at Nature Geoscience, analyzes the extent and potential cause of changes in northern surface wind speeds over the past 30 years. In it, researchers have found that surface wind speeds have declined by 5–15% over almost all continental areas in the northern mid-latitudes, and that strong winds have slowed faster than weak winds. They also note that the observed decline of surface wind in many regions of the world is a potential concern for wind power electricity production.
A new paper, penned by a group of known warmist scare mongers, claims to have proof that CO2 is the control knob that regulates Earth’s temperature. Andrew A. Lacis, Gavin A. Schmidt, David Rind, and Reto A. Ruedy, all from NASA's Goddard Institute for Space Studies, are boasting they have experimental proof that “carbon dioxide is the single most important climate-relevant greenhouse gas in Earth’s atmosphere.” Even though this climate alarmist cabal admits that H2O, in the form of water vapor and clouds, accounts for 75% of greenhouse warming, they still claim that that CO2 is king. Why? Because water's contributions are supposedly caused by feedbacks involving carbon dioxide. How have they proven that? By fiddling around with the same biased computer climate models that their other fictitious claims are based on.
One of the arguments used by critics of nuclear power is that there is not enough uranium to power a nuclear world for an extended time. The energy hungry world would just be trading looming oil shortages for uranium shortages, they claim. As with most anti-nuclear scare-mongering these charges are totally bogus. MIT has just released a major report on the nuclear fuel cycle that finds uranium supplies will not limit the expansion of nuclear power in the US or around the world for the foreseeable future. It suggests that nuclear power, even using today’s reactor technology with the wasteful once-through fuel cycle, can play a significant part in satisfying the world's future energy needs.
It is accepted that volcanic eruptions can have a major impact on short term climate. A new study in Nature Geoscience uses instrument records, proxy data and climate modeling to show that multidecadal variability is a dominant feature of North Atlantic sea-surface temperature (SST), which, in turn, impacts regional climate. It turns out that the timing of multidecadal SST fluctuations in the North Atlantic over the past 600 years has, to a large degree, been governed by changes in external solar and volcanic forcings. Solar influence is not surprising but the fact that volcanoes cause climate change lasting decades has some significant implications for those trying to model climate over the next century.
Though most of the debate among US politicians preparing for the midterm elections on November 2nd is about the economy, supporters of the warmist agenda are awakening to the fact that a sea change in the American Congress could leave climate change legislation high and dry. A list compiled by the left-leaning Wonk Room website suggests that 31 out of 37 Republican Senate candidates have recently disputed the science. This includes nine out of ten sitting senators and five of the remaining six actively oppose existing climate bills. If there was ever any doubt as to which end of the political spectrum belief in anthropogenic global warming lies on, this should make it clear that climate change is a political lever for the socialist left. There is scant support from conservatives for radical environmentalist notions. Indeed, skepticism about climate science has become a litmus tests for candidates backed by the resurgent right.
The 21st Century may well mark the beginning of the hybrid age. New and exciting developments in transportation propulsion systems promise to deliver higher performance, be more efficient and unshackle human energy consumption from the burning of fossil fuels. Once the realization that oil won't last for ever is accepted, all sorts of intriguing possibilities suggest themselves: hybrid jet planes with electric motors helping to drive their high bypass turbofans; diesel electric locomotives that no longer simply throw away the energy captured by dynamic breaking; and a new crop of super cars from Lotus, Ferrari and Porsche that don't take a back seat to any gas guzzler. The future looks green, efficient and even fun.
Any competent researcher involved with the science behind climate change will admit that CO2 is far from the only influence on global climate. It has long been known that short-lived greenhouse gases and black-carbon aerosols have contributed to past climate warming. Though the IPCC and their fellow travelers have tried to place the blame for global warming on human CO2 emissions, decades of lies and erroneous predictions have discredited that notion. For anyone still clinging to the CO2 hypothesis, a short perspective article on the uncertainty surrounding climate change in Nature Geoscience has put paid to that notion. It states that not only did other factors account for 65% of the radiative forcing usually attributed to carbon dioxide, but that it is impossible to accurately determine climate sensitivity given the state of climate science.
That humans can alter the natural environment is well known. We have been hunting, fishing and clearing land for agriculture for tens of thousands of years. More recently humans have gained the ability to drain swamps, dam rivers, level mountains and pave over darn near anything. Environmentalists think this kind of activity is abhorrent, and go so far as to claim that H. sapiens are responsible for a new major wave of extinctions. In general, animal species can either move, go extinct or adapt to human caused environmental changes. Many biologists will tell you that species just can't evolve fast enough to deal with rate of human induced change. As it turns out, this isn't exactly true.
With the UN trying to promote diminishing biodiversity as the NEXT BIG CRISIS it is interesting to note the chaos among diversity researchers. It is hard to make definitive statements regarding loss of diversity when science can not even tell us how many different creatures there are on the planet. Nevertheless, the UN has launched the International Year of Biodiversity, warning that the ongoing loss of species around the world is affecting human well-being. Yet another UN generated “science based” crisis to keep the world's citizens in a frenzy—shades of the failed global warming crisis, which the UN is rather hoping we all will forget.
Tyrannosaurs, the group of carnivorous dinosaurs that includes Tyrannosaurus rex and its closest relatives, are the most iconic and most studied of the dinosaurs. Made famous by movies, television shows and books, T. rex is the image most people think of when they hear the word dinosaur. The popular image of a tyrannosaur is that of a gigantic meat eater, like the one shown in Spielberg's Jurassic Park, but this was not always the case. T. rex was initially described 105 years ago by H. F. Osborn of the American Museum of Natural History. New fossil finds, including six new species during the past year alone, have shown tyrannosaurs to be a more diverse group that was first thought. A phylogeny that includes recently described species shows that tyrannosaurs originated by the Middle Jurassic but remained mostly small and ecologically marginal until the Late Cretaceous.
In an example of what Presidential Science Advisor John Holdren would label “global climate disruption,” a 2009 report claimed that warming surface water in the Pacific Ocean was having an impact on the frequency of tropical storms. Moreover, landfalls along the Gulf of Mexico coast and Central America were supposedly increased. Now a new study appearing in Geophysical Research Letters has found these claims to be untrue. It seems that there is little correlation between the Atlantic hurricane activity and Pacific Ocean warming. In fact, the increased tropical storm frequency in 1969 and 2004 can be readily explained by increased warmth in the Atlantic where the storms form. Once again, those looking for a smoking gun in the form of human caused climate change are forced to look elsewhere.
