              * The probability that this is caused by natural climatic processes alone is less than 5%.
              * World temperatures could rise by between 1.1 and 6.4 ÂC (2.0 and 11.5 ÂF) during the 21st century (table 3) and that:
                          o Sea levels will probably rise by 18 to 59 cm (7.08 to 23.22 in) [table 3].
                          o There is a confidence level >90% that there will be more frequent warm spells, heat waves and heavy rainfall.
                          o There is a confidence level >66% that there will be an increase in droughts, tropical cyclones and extreme high tides.
              * Both past and future anthropogenic carbon dioxide emissions will continue to contribute to warming and sea level rise for more than a millennium.
              * Global atmospheric concentrations of carbon dioxide, methane, and nitrous oxide have increased markedly as a result of human activities since 1750 and now far exceed pre-industrial values over the past 650,000 years

      The following is the Dec. 13th 07 letter to Ban Ki-moon, Secretary-General of the United Nations on the UN Climate conference in Bali:

      Dear Mr. Secretary-General,

      Re: UN climate conference taking the World in entirely the wrong direction

      It is not possible to stop climate change, a natural phenomenon that has affected humanity through the ages. Geological, archaeological, oral and written histories all attest to the dramatic challenges posed to past societies from unanticipated changes in temperature, precipitation, winds and other climatic variables. We therefore need to equip nations to become resilient to the full range of these natural phenomena by promoting economic growth and wealth generation.

      The United Nations Intergovernmental Panel on Climate Change (IPCC) has issued increasingly alarming conclusions about the climatic influences of human-produced carbon dioxide (CO2), a non-polluting gas that is essential to plant photosynthesis. While we understand the evidence that has led them to view CO2 emissions as harmful, the IPCC's conclusions are quite inadequate as justification for implementing policies that will markedly diminish future prosperity. In particular, it is not established that it is possible to significantly alter global climate through cuts in human greenhouse gas emissions. On top of which, because attempts to cut emissions will slow development, the current UN approach of CO2 reduction is likely to increase human suffering from future climate change rather than to decrease it.

      The IPCC Summaries for Policy Makers are the most widely read IPCC reports amongst politicians and non-scientists and are the basis for most climate change policy formulation. Yet these Summaries are prepared by a relatively small core writing team with the final drafts approved line-by-line by Âgovernment Ârepresentatives. The great Âmajority of IPCC contributors and Âreviewers, and the tens of thousands of other scientists who are qualified to comment on these matters, are not involved in the preparation of these documents. The summaries therefore cannot properly be represented as a consensus view among experts.

      Contrary to the impression left by the IPCC Summary reports:

      Â Recent observations of phenomena such as glacial retreats, sea-level rise and the migration of temperature-sensitive species are not evidence for abnormal climate change, for none of these changes has been shown to lie outside the bounds of known natural variability.

      Â The average rate of warming of 0.1 to 0. 2 degrees Celsius per decade recorded by satellites during the late 20th century falls within known natural rates of warming and cooling over the last 10,000 years.

      Â Leading scientists, including some senior IPCC representatives, acknowledge that today's computer models cannot predict climate. Consistent with this, and despite computer projections of temperature rises, there has been no net global warming since 1998. That the current temperature plateau follows a late 20th-century period of warming is consistent with the continuation today of natural multi-decadal or millennial climate cycling.

      In stark contrast to the often repeated assertion that the science of climate change is "settled," significant new peer-reviewed research has cast even more doubt on the hypothesis of dangerous human-caused global warming.

The fossil fuels come from ancient organic matter that's formed and been sequestered underground over many millions of years. It happened very very slowly. Humans have taken millions of years worth of coal and oil, and reintroduced all that ancient carbon back into the biosphere. We'll have returned all that ancient carbon into the environment within a mere couple hundred years. That's pretty damn abrupt in geologic time scales, and a shift in carbon levels will have never occurred that quickly before.

    Ummm, I think you missed the point there.

    Making ice, melting salt, and running pumps are methods for storing energy (like a battery) so when you are making too much power you can save up the excess and extract it later when you are producing too little power.

    The poster wasn't suggesting that power companies become molten salt salesmen.

    Duh!

    Anyone who has believed otherwise has been caught drinking too much of the spiked Kool-Aid.

    We live in an effectively finite ecosystem with finite resources. Had we not allowed human population to explode as it has, particularly in the last 200 years, virtually none of what we consider "crises" would even be problems worth noting yet. We would still have had to address them eventually perhaps, but we would have had centuries more to learn before then. Unfortunately the species is very adept at burning the candle at both ends. What we're experiencing now is not much different than the crash of withdrawal after binging on some hallucinogen. The morning after is always a bitch.

    Again, human overpopulation is the 800-pound Samsonite gorilla in the room. Until we deal with that, none of the rest is anything but posturing.

    "The supposed "global cooling" consensus among scientists in the 1970s -- frequently offered by global-warming skeptics as proof that climatologists can't make up their minds -- is a myth, according to a survey of the scientific literature of the era....

    But Thomas Peterson of the National Climatic Data Center surveyed dozens of peer-reviewed scientific articles from 1965 to 1979 and found that only seven supported global cooling, while 44 predicted warming. Peterson says 20 others were neutral in their assessments of climate trends. The study reports, "There was no scientific consensus in the 1970s that the Earth was headed into an imminent ice age.

    "A review of the literature suggests that, to the contrary, greenhouse warming even then dominated scientists' thinking about the most important forces shaping Earth's climate on human time scales."

    I'm pretty sure you missed his point entirely. They aren't running "another business" but instead finding some temporary storage place for the excess electricity. That's why the GP said "over supply utilization system".

    Melting salt sucks up power and then generates it when you use that trapped heat to make steam later. Running pumps lets you store power with gravity. Pump water up higher, it releases the potential energy when it comes back down. And there are many other methods.

    BS. Seriously. We buy new cars anyway, so why NOT more efficient ones? Besides, if everyone drove dramatically more efficient vehicles it ALSO mean reducing (or eliminating) our trade deficit in oil. How does THAT trash the economy?

    Eliminate dependence on foreign oil, and it also means we don't have to spend billions sending our kids off to die every time the Middle East hicups. How does THAT trash the economy?

    And there are as many economic OPPORTUNITIES in doing the right things as there are not doing them. Solar cell have to be manufactured and installed. Wind turbines constructed. And so on. That spells jobs.

    Less polution. Reduced environmental impact. Economic growth. Reduced trade deficit. Eliminate dependence on foreign oil. And perhaps, taking out some insurance on our planet. There are many, many, many reasons for making the investment.

    And practically none for NOT doing so...

    Little to no oxygen. Which I think is a more immediate problem than acidification.

    If we have documentation about alkaline runoff - there ought to be more documentation about acid runoff.

    It's not so much there would be acid runoff, not because of CO2 at least. CO2 is an acidic oxide, which water will absorb. On land though plants will use it to grow.

    Oh, something I just recalled. You know how some people say "let's plant more trees"? While CO2 boosts the growth of some trees, it slows the growth of other trees. And guess what plant loves CO2? Poison ivy. It grows faster with higher CO2 levels.

    That's pretty damn abrupt in geologic time scales, and a shift in carbon levels will have never occurred that quickly before.

    As it happens, we have one (1) known occurrence of similarly abrupt increase in CO2 level. At the end of the Permian, a volcano system known as the "Siberian traps" set huge coal beds afire (think pacific "ring of fire" meets middle east oil fields). A large percentage of the worlds coal was burned in a geological eye-blink.

    The was immediately followed by the Permian mass extinction, the largest mass extinction event in the worlds history, when pretty much every living thing on Earth died and only a handful of species (think things like cockroaches) had enough surviving members to struggle through.
