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.
The 2nd anniversary of “Climate Fools Day” is almost upon us and it is starting to attract the attention of UK MP's. This year's Climate Fools Day Rally will be held Wednesday, October 27th 2PM at Parliament and we encourage all climate skeptics who can to attend. Our friends at Climate Realists have posted the following update on the planned festivities:
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.
Faced with a public that has rejected the IPCC generated global warming crisis and is increasingly deaf to the rantings of eco-activists, a UK group known as 10:10 has revealed the true nature of the environmentalist fringe community in a desperate attempt to recapture the public's attention. The mechanism chosen is a brief video that shows a charming group of English school children being “educated” about global warming by their teacher. When a few students refuse to go along with the green propaganda love-fest the teacher pushes a button, which causes the recalcitrant children to explode.
