THERE are four official global temperature data sets and there has been much debate and discussion as to which best represents change in global temperature.
Tom Quirk has analysed variations within and between these data sets and concludes there is 1. Substantial general agreement between the data sets, 2. Substantial short-term variation in global temperature in all data sets and 3. No data set shows a significant measurable rise in global temperature over the twelve year period since 1997.
INSTEAD of rising temperatures, the annual average temperature in Mississippi has declined over the past century. Instead of an increasing frequency of drought, the state’s moisture conditions have improved over the long run. Instead of failing crops, the state’s agricultural yields have been increasing. Natural cycles in the regional climate can largely explain changes in patterns of hurricane activity.
These are some of the findings in a new report entitled ‘Observed Climate Change and Negligible Global Effects of Greenhouse-gas Emission Limits in the State of Mississippi’ recently published by the Science and Public Policy Institute.
GLOBAL warming theory is not that complicated. According to Michael Hammer it can be incorporated into a simple model which readers can build themselves on an excel spread sheet.
Mr Hammer gives detailed instructions and formulae to enter for his DIY climate change model. The model then calculates the temperature rise from carbon dioxide plus water vapour forcing and allows for the time constant in the system.
A temperature rise by 2070 of 3C for a business as usual scenario, however, gives model output that is not compatible with what we know of past climates. So, what is wrong with Mr Hammer’s model?
THEY went to the Arctic lamenting global warming, but ever since they got there they have been wishing for warmer weather. That was how I started a post earlier this year, about three Brits who set off for the North Pole in February hoping to draw attention to the issue of global warming and take a few measurements of ice thinning along the way.
Still 500 kilometres from the North Pole the team now plan to be “lifted off the ice” by the end of this week because it’s just too cold – too cold to keep going and too cold to get the measurements they intended.
According to Steven Goddard blogging at WUWT, “I believe that they have done a fantastic job educating the public about the Arctic. Their mission has been followed breathlessly by BBC and Guardian reporters, who previously believed that the Arctic had melted and become a place for sunbathing.
“Following the daily reports of ice, cold, frostbite, hypothermia, pain and general misery being endured by the team – even the most daft newspaper reporter must be aware now that the Arctic is a very cold and icy place.”
ACCORDING to the anthropogenic global warming (AGW) hypothesis while surface temperatures may vary from year to year, as long as we spew out carbon dioxide there will be a gradual accumulation of heat in the climate system eventually resulting in a climate crisis.
In 2005, NASA boss James Hansen stated in an article in the journal ‘Science’ that confirmation of the planetary energy imbalance can be obtained by measuring the heat content of the oceans which are the principal reservoir for excess energy.
A problem for the AGW hypothesis now, is that the oceans have been cooling. Indeed there is no known mechanism to account for what some describe as vast amounts of missing heat, suggesting that contrary to the AGW hypothesis, heat is not accumulating in the climate system and there is no longer any radiative imbalance from all the carbon dioxide and other greenhouse gases.
According to William DiPuccio, in a guest post at the blog ‘Climate Science’, this not only demonstrates that the United Nation’s Intergovernmental Panel on Climate Change models are failing to accurately predict global warming, but also presents a serious challenge to the integrity of the AGW hypothesis.
Mr DiPuccio concludes “When all is said and done, if the climate system is not accumulating heat, the hypothesis is invalid.”
