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.

Why 2014 Won’t Be the Warmest Year on Record

Much is being made of the “global” surface thermometer data, which three-quarters the way through 2014 is now suggesting the global average this year will be the warmest in the modern instrumental record. I claim 2014 won’t be the warmest global-average year on record. ..if for no other reason than this: thermometers cannot measure global […]

Disinvestment: Political Correct Hypocrisy

The so-called “disinvestment” movement fails to meet any standard of moral legitimacy. Disinvestment sounds powerful but if those who have joined the campaign meant to sell their holdings in fossil energy companies, why didn’t they say that they had done so? If the goal is to discourage others from investing in those companies, then arrogance […]

The Myth of Carbon Pollution – Powerpoint presentation

On October 15, 2014 Dr. William Happer, Chairman of the George C. Marshall Institute, discussed “The Myth of Carbon Pollution.” “Carbon pollution” is a propaganda slogan for the campaign against carbon dioxide (CO2). It is not science. Atmospheric CO2 is not a pollutant but is essential for plant growth. Current CO2 levels are far below […]

Ebola outbreak partly fueled by misguided priorities and misallocated resources

With each new case of the Ebola virus reported by the media, there is also more speculation about a pandemic if Ebola gets out of West Africa, which unfortunately it has. A pandemic is an epidemic that spreads across continents. The world has experienced pandemics at least as far back as the Middle Ages, when […]

North Atlantic Set to Cool Slightly, Says Research

New research into the links between currents in the North Atlantic and the pressure system that sits above them enables future changes in North Atlantic sea surface temperatures to be better predicted – and it forecasts cooling, with implications for Europe’s weather.

Root Cause Analysis of the Modern Warming

For years, climate scientists have followed reasoning that goes from climate model simulations to expert opinion, declaring that to be sufficient. But that is not how attribution works. The concept of attribution is important in descriptive science, and is a key part of engineering. Engineers typically use the term “root cause analysis” rather than attribution.

EU leaders divided over costs as climate deal talks start in earnest

European leaders aim to agree a new decade of energy policy to cut climate-warming gas emissions to 2030 at an EU summit on Thursday, but sharp differences over sharing the costs mean that securing a deal will be difficult.
