The established science shows carbon dioxide is a greenhouse gas, that humans produce greenhouse gas emissions, and that humans have had some effect on Earth’s climate. However, important issues remain unanswered: Are humans or other natural conditions responsible for the majority of the past century’s warming? Is global warming, on balance, bad or good for humanity? If humans are responsible, and the results are generally harmful, what are the best responses? On each of these points, there is widespread disagreement, and anyone who says otherwise is lying.

KaiserJeep wrote:My hypothesis is that human activities have had minimal effect upon climate. The Milanković cycles alone have produced periodic glaciation and brief periods of intense warm climate between glaciation.
KaiserJeep wrote:The truth of the matter would be that you cannot precisely calculate anything when it comes to climate. We don't have nearly enough data collection and much of the surface temperature data collected is compromised by the urban heat island effects. In fact, there is only one way that we can collecte valid temperature data, which is with infrared sensors facing Earth from space.
Unfortunately such sensors show that the Earth is cooling, not warming.
Even if it wasn't inconveniently cooling, the presence of warming does not confirm or disprove the theory of AGW.
Climate change sceptics suffer blow as satellite data correction shows 140% faster global warming
New research 'substantially undermines' claims that satellite data proved the Earth was not warming as quickly as thought, Dr Zeke Hausfather says
http://www.independent.co.uk/news/scien ... 16676.html
Writing in the Journal of Climate, the scientists said: “The changes result in global-scale warming … about 30 per cent larger than our previous version of the dataset.
“This change is primarily due to the changes in the adjustment for drifting local measurement time. The new dataset shows more warming than most similar datasets constructed from satellites or radiosonde [weather balloon] data.”
In an article on the Carbon Brief website about the new research, data scientist Dr Zeke Hausfather said it showed an even faster rate of warming since 1998 – at nearly 140 per cent – than previous satellite-based studies......

Actually the warming that is occurring does confirm the theory of AGW.
Thats how science works.....a hypothesis is generated and data is collected to test the hypothesis. IF the data is consistent with the hypothesis, then it confirms the validity of the hypothesis.
The theory of AGW predicts we should be seeing global warming due to the accumulation of greenhouse gases in the atmosphere, and that is just what the data shows.
Cheers!

...storms in the winter of 2013–2014 transported boulders at elevations up to 29 m above high water, and at inland distances up to 222 m.
Among the clasts transported are eighteen weighing more than 50 t, six of which exceed 100 t. The largest boulder moved during those storms weighs a fairly astonishing 620 t.
