Global warming not cosmological

Postby Brian Jordan » Fri Mar 08, 2013 7:59 pm

Well, cosmological probably isn't the right word - orbital or axial or cyclical or something. Whatever, this article - which I haven't followed up - says that such variations have indeed influenced the climate but have now been surpassed by combustion* emissions.
The study concluded that global temperatures gradually rose after the end of the ice age for about 6,000 years due to changes in the tilt of the Earth’s axis, which brought more solar radiation to the northern hemisphere in summer.

This warming trend reached a peak about 5,000 years ago when cooling began to lower average global temperatures by about 0.8C. However, around the start of the 20th Century this trend went into reversal, with global temperatures increasing by 0.8C – but over decades rather than millennia.

“Global temperature, therefore, has risen from near the coldest to the warmest levels of the Holocene within the past century, reversing the long-term cooling trend that began about 5,000 years before present,” the study says.

*combustion - something a certain creationist professor is well versed in.
