About

Human activity, such as the burning of fossil fuels to power our homes and businesses and changes to the land caused by the rise of modern cities and expanded agriculture, undoubtedly affect the global environment. It is the extent of that effect and how it relates to changes in the modern climate which is the subject of current scientific debate.

Wise, effective climate policy flows from a sound scientific foundation and a clear understanding of what science does and does not tell us about human influence and about courses of action to manage risk. Many of the temperature data and computer models used to predict climate change are themselves as uncertain as are our understanding of important interactions in the natural climate.

Are calls about the uncertainty in the state of scientific knowledge a call for no action? Nothing could be further from the truth. The message to policy makers is not to delay actions until uncertainties are reduced. Rather, actions should flow from the state of knowledge, should be related to a long-term strategy and objectives and should be capable of being adjusted- one way or the other- as the understanding of human influences improves. There is a sufficient basis for action because the climate change risk is real. Yet it is equally true that actions must not be predicated on speculative images of an apocalyptic vision of life in the near future.

Pope Francis’ Call for Global Governance

The Pope’s encyclical appears to focus on climate change and environmental degradation but the larger focus is his indictment of capitalism and the presumed greed that it spawns, leading Pope Francis to call for a global government solution. The language in the encyclical looks like it came from the UN’s Agenda 21 and the Club […]

2015 Will Be Record Warm in Surface Temperatures…But Still Below Model Forecasts

With 5/12 (41.7%) of the votes counted, John Christy and I are now prepared to call 2015 as the winner of the Warmest Year in the Thermometer Record election. The latest exit polling of El Nino forecasts suggests an unusually hot turnout from the East Pacific region this year, which is why we are calling […]

What Causes the Greenhouse Effect?

I’ve had a request to (once again) go through an explanation of the (poorly-named) Greenhouse Effect (GHE). Hopefully there is something which follows that will help you understand this complex subject. The greenhouse effect usually refers to a net increase in the Earth’s surface temperature due to the fact that the atmosphere both absorbs and […]

Greenpeace? Or Greendeceit?

I just about made it out of Heartland’s 10th International Conference on Climate Change, now winding down near Capitol Hill, without having to deal with one of the 25 media outlets registered there known to be antagonistic to the view that global warming is neither all human-caused nor dangerous. Then, a sharply dressed, very young […]

Greenland Temperatures Weaken Theory CO2 Drives Climate

If volcanic eruptions are blamed for the cooling periods, especially in Greenland, with lack of eruptions blamed for warming, only some of the cooling dips are explained. The other cooling episodes are presumably because of ocean current/temperature cycles or the sun.

Paper finds ‘pronounced influence of solar activity on global climatic processes’

A paper published in Palaeogeography, Palaeoclimatology, Palaeoecology finds “a pronounced influence of solar activity on global climatic processes” including in “Asia, Europe, North and South America, Australia, and the Arctic and Antarctica.”

Claim: Credit Agencies are miscalculating climate risk

The Center for International Environmental Law thinks that Credit Agencies are miscalculating the risk of climate change – that climate change might be the cause of the next financial crisis.
