POPSHow to Talk to a Global Warming Skeptic (FAQ) More common questions and myths answered at the source, thoroughly cross-referenced and conveniently categorized and sub-categorized by type of argument: Stages of Denial Scientific Topics Types of Argument Levels of Sophistication A nice reference that's updated with fresh comments. Many "skeptics" often are unaware (by choice or by circumstance) that their common questions have already been addressed by scientists long ago.

POPSNew clues on "The Great Dying" The lessons of the Permian-Triassic massacre are "directly applicable to the present," said John Isbell, a geoscientist at the University of Wisconsin in Milwaukee. He said the world today is in danger of exceeding a CO2 "threshold" that could set off an environmental upheaval as great as the one 251 million years ago.

POPSFamed Geneticist Creating Life Form That Turns CO2 to Fuel Scientists put "suicide genes" into their living creations so that if they escape the lab, they can be triggered to kill themselves. Venter said he is also working on organisms that make vaccines for the flu and other illnesses. Suicide genes and vaccines mentioned in the same breath, sort of creeps me out a little. :roll:

POPSGeologic Evidence of the Cause of Global Warming and Cooling The warming over the past 50 years is hardly even noticeable on the 15,000 year graph above. Compare the peaks about every 800-1000 years for the past 10,000 years (since the last full ice age), all are much warmer than what we're experiencing now. In fact the last 1,000 years has been unusually cool for this interglacial period, just looking at the graph it certainly looks like we've been over due for warming (or if our interglacial period is over another full ice age which would be much worse).

POPSGlobal Warming Scientist Comes Clean
1. The greenhouse signature is missing. We have been looking and measuring for years, and cannot find it. Each possible cause of global warming has a different pattern of where in the planet the warming occurs first and the most... We have been measuring the atmosphere for decades using radiosondes: weather balloons with thermometers that radio back the temperature as the balloon ascends through the atmosphere. They show no hot spot. Whatsoever. If there is no hot spot then an increased greenhouse effect is not the cause of global warming. 2. There is no evidence that carbon emissions cause significant global warming. None. ... 3. The satellites that measure the world's temperature all say that the warming trend ended in 2001, and that the temperature has dropped about 0.6C in the past year 4. ice cores show that in the past... half a million years, the temperature rises occurred on average 800 years before the accompanying rise in atmospheric carbon.

POPSNASA: 70% of climate change due to Pacific oscillations, not CO2 What this means is no matter how much you change your CO2 footprint, how much you try to be CO2 green, no matter how much liberal governments tax you - you cannot save the planet from its natural cycles. Say they reduced the CO2 25%. Say the CO2 is the driver for the remaining 30% of Global Warming (which it cannot be, but let’s just be only half as ridiculous as the IPCC), then all that effort would only impact 7.5% of the forces driving the global climate. The other 92.5% would roll on, impervious to the effort. And since CO2 is not 100% of the remaining 30% of the equation (more like 10%), a more realistic expectation is that all the suffering that would go into dropping CO2 levels by 25% would result in a less than 1% change in the forces driving our climate.

POPSA $45T Clean Energy Revolution Oh yeah....this is huge! Bigger than the internet and telecommunications revolution...the energy revolution seems poised to be the defining innovation of this century. In addition to creating a much more stable source of energy and helping the environment, the opportunity for investment and new jobs makes this the most exciting opportunity i've ever seen.

POPSThe CO2 extractor Every living thing relies on CO2 being in the atmosphere. That said, why do environmental alarmists oppose the CO2 scrubber? The argument that it is inefficient just doesn't fly because all technology becomes cheaper and more efficient over time. I think we all know the reason why they oppose it. The CO2 scrubber does not allow them to control your life.

POPSThere is no climate crisis: Hoax revealed The IPCC’s 2007 climate summary overstated CO2’s impact on temperature by 500-2000%; CO2 enrichment will add little more than 1 °F (0.6 °C) to global mean surface temperature by 2100; Not one of the three key variables whose product is climate sensitivity can be measured directly; The IPCC’s values for these key variables are taken from only four published papers, not 2,500; The IPCC’s values for each of the three variables, and hence for climate sensitivity, are overstated; “Global warming” halted ten years ago, and surface temperature has been falling for seven years; Not one of the computer models relied upon by the IPCC predicted so long and rapid a cooling; The IPCC inserted a table into the scientists’ draft, overstating the effect of ice-melt by 1000%; Mars, Jupiter, Neptune’s largest moon, and Pluto warmed at the same time as Earth warmed; In the past 70 years the Sun was more active than at almost any other time in the past 11,400 years.

POPSAn inconvenient truth Al Gore left out of his movie According to this writer, Gore never really comes clean in his film about precisely how much sacrifice will be required of residents of industrialized countries if we are to stop global warming. Estimates suggest we'd have to cut CO2 emissions by 90%. Something tells me that's not going to happen.

POPSA dash of lime -- a new twist that may cut CO2 levels back to pre-industrial levels Tim Kruger, a management consultant at London firm Corven is the brains behind the plan to resurrect the lime process. He argues that it could be made workable by locating it in regions that have a combination of low-cost 'stranded' energy considered too remote to be economically viable to exploit – like flared natural gas or solar energy in deserts – and that are rich in limestone, making it feasible for calcination to take place on site.

POPSThe Myth of Clean Coal "The urgent motive for an ad campaign this time is the possibility of federal global warming legislation. A cap-and-trade scheme for carbon dioxide emissions may come to a vote in the Senate this June. Coal is also struggling to overcome fierce resistance at the state and local level; Kansas, Florida, Idaho, and California have already effectively declared a moratorium on new coal-fired power plants. Nationwide, 59 new coal-fired power plant projects died last year (of 151 proposed), mostly because local authorities refused to grant permits or because big banks withheld financing. Both groups are alarmed about the lack of practical remedies to deal with coal’s massive CO2 emissions."

POPSCivilization Threatened by Global Warming - Six Leading Scientists Say See first source for the full article. Present knowledge does not permit accurate specification of the dangerous level of human-made GHGs. However, it is much lower than has commonly been assumed. If we have not already passed the dangerous level, the energy infrastructure in place ensures that we will pass it within several decades. We conclude that a feasible strategy for planetary rescue almost surely requires a means of extracting GHGs from the air. Development of CO2 capture at power plants, with below-ground CO2 sequestration, may be a critical element. Injection of the CO2 well beneath the ocean floor assures its stability (House et al. 2006). If the power plant fuel is derived from biomass, such as cellulosic fibres grown without excessive fertilization that produces N2O or other offsetting GHG emissions, it will provide continuing drawdown of atmospheric CO2.
