To buttress the claim that solar forcing has effectively played since the mid-20th century, the IPCC has shown preference for modeled reconstructions of solar activity (i.e., the PMOD) that show a stable or decreasing trend since the 1970s. Why? Because if the modeled results can depict steady or decreasing solar activity since the last few decades of the 20th century – just as surface temperatures were rising – then attributing the post-1970s warming trend to human activity becomes that much easier.
The combined Hadley Centre and Climatic Research Unit (HadCRUT) data set — which is featured in the Intergovernmental Panel on Climate Change (IPCC) reports — underwent a revision from version 3 to version 4 in March of 2012. This was about a year before the latest IPCC report was to be released (2013). At the time (early 2012), it was quite inconvenient to the paradigm that HadCRUT3 was highlighting a slight global cooling trend between 1998 and 2012, as shown in the graph below (using HadCRUT3 and HadCRUT4 raw data from ). So, by changing versions, and by adjusting the data, the slight cooling was changed to a slight warming trend.
CO2 survives in the atmosphere for a long time—up to many centuries—so its heat-trapping effects are compounded over time. Of the many heat-trapping gases, CO2 puts us at the greatest risk of irreversible changes if it continues to accumulate unabated in the atmosphere—as it is likely to do if the global economy remains dependent on fossil fuels for its energy needs. To put this in perspective, the carbon we put in the atmosphere today will literally determine not only our climate future but that of future generations as well.

Over the last century, global average temperature has increased by more than 1°F (0.7°C). The 2001-2010 decade is the warmest since 1880—the earliest year for which comprehensive global temperature records were available. In fact, nine of the warmest years on record have occurred in just the last 10 years. This warming has been accompanied by a decrease in very cold days and nights and an increase in extremely hot days and warm nights. The continental United States, for example, has seen record daily highs twice as often as record daily lows from 2000 to 2009. While the record shows that some parts of the world are warming faster than others, the long-term global upward trend is unambiguous.
This is a perfect picture for climate change, in a way, because you have the impression they are in the middle of the ocean and they are going to die with a coke in their hands.
2, 2007 Denis Simard, a representative of Environment Canada, distributed that ladys photo to 7 media agencies, including the Associated Press, and timed it to coincide with the release of the United Nations major global warming report in Paris, France on Feb 3rd.
Nothing but straw men from you. No one has written that there was “no warming” after the 1970s. Instead, this is what the instrumental (rural) temperatures look like:
If not for adjustments and manipulation, the instrumental record would, in reality, look like the many reconstructions of Northern Hemisphere temperatures that show an oscillation rather than a nearly-linear warming trend since 1900, with the peak of the 2000s meeting or only slightly exceeding the peak reached in the 1940s. After all, as of 1981 (Hansen et al., 1981) NASA had NH rising by 0.8 C between 1880 and 1940, then dropping by -0.5 C through to 1970. Now it’s more like +0.3 C between 1880 and 1940 (instead of 0.8 C), a cooling of just -0.1 C (instead of -0.5 C), and then an abrupt warming that is almost twice as high as the satellite record since the 1970s. They’ve adjusted their own instrumental record to fit the narrative of a linear warming trend, SebastianH. And it doesn’t match up with the proxy evidence…nor with rural-only instrumental temperatures (that are not affected by urbanization).
Senate report quotes 400+ scientists who originally bought the global warming hoax, and are now confessing that they don't believe in it any more. Yes, Sen.
Must Wellesley’s 2007 seniors scour their term papers on global warming for phrases that could derail their presidential ambitions in the year 2046?
(sigh...) It ends with Hurricane Katrina and Boston almost losing the pennant. It is Hollywood at its finest, and the Deacons of La La Land give it an Oscar. Even the Nobel Committee is impressed, gives it two thumbs-up and a Nobel Prize to Gore and the other members of the IPCC for the many lives that will be saved in the future because of this brilliant early warning. And, there's still time for we miserable humans to "save" the planet by buying "carbon offsets" accomplished best by investing in Al Gore's British company which buys stock in other companies that will benefit from a world-wide global warming hysteria (keeping a healthy cut) and making, perhaps, Al Gore the richest former Vice President in history. That will buy a lot of SUV's, jets, and large mansions with mega-electric bills. Everyone wins except the taxpayer and businessman, who are soon to pay a very heavy price.
Lindzen, in his paper at the 2005 Yale Center for Globalization conference clearly points to one particular pro-hoax web site calling itself "" which tells us that it is all about "climate science from climate scientists", featuring among others, the now universally discredited work of Michael Mann and others who were too quick to become his overnight followers. The site isn't actually run by "scientists", it's actually run by , which specializes in spreading environmental junk science on behalf of numerous clients who stand to financially benefit from scare tactics through environmental fear mongering. Lindzen says, "
