Congressional Testimony: A Surprising Consensus On Climate
Lasrick writes: Many legislators regularly deny that there is a scientific consensus, or even broad scientific support, for government action to address climate change. Researchers recently assessed the content of congressional testimony related to either global warming or climate change from 1969 to 2007. For each piece of testimony, they recorded several characteristics about how the testimony discussed climate. For instance, noting whether the testimony indicated that global warming or climate change was happening and whether any climate change was attributable (in part) to anthropogenic sources. The results: Testimony to Congress—even under Republican reign—reflects the scientific consensus that humans are changing our planet's climate.

http://davidappell.blogspot.ca... "Johnson's remarks arose from a 1965 report to his Administration, “Restoring the Quality of Our Environment,” by the Environmental Pollution Panel of the President’s Science Advisory Committee, which had a chapter on CO2’s potential to cause warming.
Exactly. In the news. Not in peer reviewed scientific papers.
You know what else was in the news? UFOs. Bigfoot. Lassie.
It's probably a skewed result because half of the testimonies will have been selected by republicans because they are reject the mainstream science. This makes the finding even more surprising. For a more balanced view you can look to the statements made by scientific organizations.

You are missing what parts scientists are well agreed upon:
1.The instrumental record, which spans about 100 years, shows a clear warming trend.
2. CO2 is a greenhouse gas and increasing it's concentration will increase heat storage.
3. CO2 concentrations as observed for about the last 60ish years have been increasing.
4. Humans have been steadily contributing CO2 to the atmosphere for about the last 100 years.
5. The above points clearly are strong evidence that the recent warming has been influenced by human behaviour.
That about encompasses the consensus. 90% of everything that everyone is talking about though does NOT have a broad consensus and is still being actively studied, things like:
1.What quantitative relationship do our CO2 emissions have to future temperature change?
2. What cost is there to us from future temperature change.
3. What cost is there to us for reducing our CO2 emissions by a set factor.
Climate models are one of the key parts to answering these questions, and they are getting better at helping us study our theories on how climate works. Regrettably, the reality is that climate models still do NOT accurately predict or model global Top Of Atmosphere energy imbalance. One of the key tuning processes in model development is still adjusting loosely bound or poorly understood parameters, like clouds, to force a reasonable behaviour of global TOA energy. I hate to have to point it out, but long term predictions of climate, are pretty much entirely driven by TOA energy imbalance as it IS the entirety of the greenhouse effect.
