Recent data also indicate the warmest year on record was still 1933, not 1998 as claimed by NASA's Jim Hanson, who helped create the climate models used to make their predictions.
Reports on arctic sea ice suggest a return to levels not seen since the late 1970's before warming was detected.
All this occurring in an environment containing more man made CO2 than ever before.
In the 1970's the same climate models predicted an approaching ice age brought on by the burning of fossil fuels. Movies were made and news magazines were producing stories similar to the ones seen today, each trying to achieve the same result: convincing the uninformed masses to accept legislation designed to prevent the alleged calamity from happening and to accept the constraints placed upon them by said legislation, especially in the form of higher costs. Interesting thing about computer models is you can change the outcome by changing the inputs.
The UN is an organization that among other things, receives money from rich countries and gives it to poor countries. The UN is corrupt and therefore the IPCC is. Rich countries use fossil fuel to produce their great wealth. The IPCC has determined that using fossil fuels for producing great wealth will damage the planet and the impoverished peoples in it. They don't suggest to stop using fossil fuel, they propose extracting more wealth from the rich countries. Thus: AGW in the UN view is more about money and control than about the saving planet or its people.
All this talk of climate change implies humans are causing the change. A study of history will tell us otherwise.
