Nature, Not Human Activity, Rules the Climate

From Science & Environmental Policy Project (SEPP). The NIPCC (Nongovernmental International Panel on Climate Change) was created by a group of concerned scientists who wanted to explore all the evidence regarding global warming. There results are significant and published in the PDF linked above.

1. There is very weak evidence that the causes of the current warming are anthropogenic (Section 2). 2. There is far more robust evidence that the causes of the current warming are natural (Section 3). 3. Computer models are unreliable guides to future climate conditions (Section 4). 4. Sea-level rise is not significantly affected by rise in GH gases (Section 5). 5. The data on ocean heat content have been misused to suggest anthropogenic warming. The role of GH gases in the reported rise in ocean temperature is largely unknown (Section 6) 6. Understanding of the atmospheric carbon dioxide budget is incomplete (Section 7). 7. Higher concentrations of CO2 are more likely to be beneficial to plant and animal life and to human health than lower concentrations (Section 8). 8. The economic effects of modest warming are likely to be positive and beneficial to human health (Section 9).

Their overall conclusion follows:

Our imperfect understanding of the causes and consequences of climate change means the science is far from settled. This, in turn, means proposed efforts to mitigate climate change by reducing GH gas emissions are premature and misguided. Any attempt to influence global temperatures by reducing such emissions would be both futile and expensive (Section 10).
