Global warming study

A new global warming study predicts that many current climate zones will vanish entirely by the year 2100, replaced by climates unknown in today's world.
Global climate models for the next century forecast the complete disappearance of several existing climates currently found in tropical highlands and regions near the poles, while large swaths of the tropics and subtropics may develop new climates unlike anything seen today. Driven by worldwide greenhouse gas emissions, the climate modelling study uses average summer and winter temperatures and precipitation levels to map the differences between climate zones today and in the year 2100 and anticipates large climate changes worldwide.

The programme claimed to lay bare all the fallacies that have created the "great myth" that is man-made global warming. However, the programme itself was riddled with holes. We mention a few of these issues below, and provide links to other websites that have done a good job of outlining the programme's flaws.
As New Scientist's editor, Jeremy Webb, put it: previously climate sceptics were seen to deconstruct the arguments of climate change scientists. What was different about last week's documentary was that it constructed a complete argument to explain why our planet's climate is changing - in essence, variations in solar activity.

Based on three years of observations from the SCIAMACHY instrument aboard ESA’s Envisat, scientists have produced the first movies showing the global distribution of the most important greenhouse gases – carbon dioxide and methane – that contribute to global warming.
The importance of cutting emissions from these ‘anthropogenic’, or manmade, gases has been highlighted recently with European Union leaders endorsing binding targets to cut greenhouse gases by at least 20 percent from 1990 levels by 2020. Further illustrating the urgency to combat global warming, Britain became the first country last week to propose legislation for cutting the gases.

This winter was the warmest on record worldwide.
A new report has come just over a month after the Intergovernmental Panel on Climate Change said global warming is very likely caused by human actions and is so severe it will continue for centuries.
The National Oceanic and Atmospheric Administration said the combined land and ocean temperatures for December through February were 1.3 degrees Fahrenheit above average for the period since record keeping began in 1880.
The report said that during the past century, global temperatures have increased at about 0.11 degrees per decade. But that increase has been three times larger since 1976, NOAA's National Climatic Data Centre reported.
Most scientists attribute the rising temperatures to so-called greenhouse gases which are produced by industrial activities, automobiles and other processes. These gases build up in the atmosphere and trap heat from the sun somewhat like a greenhouse.

The great global warming swindle
Are you green? How many flights have you taken in the last year? Feeling guilty about all those unnecessary car journeys? Well, maybe there's no need to feel bad.
According to a group of scientists brought together by documentary-maker Martin Durkin, if the planet is heating up, it isn't your fault and there's nothing you can do about it.

The UK government is set to achieve only a third to a half of its overall policy target for reducing greenhouse gas emissions by 2020.

BBC Dispatches reports:
The expert-reviewed audit by the UCL Environment Institute is the first comprehensive investigation into the real impact of the Government's carbon-cutting policies across all government departments mandated with reducing greenhouse gas emissions. Each of the four most important sectors: Energy Supply, Business, Transport and Domestic have been reviewed.

Martian Climate change

Simultaneous warming on Earth and Mars suggests that our planet's recent climate changes have a natural—and not a human- induced—cause, according to one scientist's controversial theory.
Earth is currently experiencing rapid warming, which the vast majority of climate scientists says is due to humans pumping huge amounts of greenhouse gases into the atmosphere.
Mars, too, appears to be enjoying more mild and balmy temperatures.
In 2005 data from NASA's Mars Global Surveyor and Odyssey missions revealed that the carbon dioxide "ice caps" near Mars's south pole had been diminishing for three summers in a row.
Habibullo Abdussamatov, head of the St. Petersburg's Pulkovo Astronomical Observatory in Russia, says the Mars data is evidence that the current global warming on Earth is being caused by changes in the sun.
