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.

How Much of Atmospheric CO2 Increase is Natural?

I frequently get asked the question, if natural CO2 emissions are about 20 times what anthropogenic emissions are, how do we know that all of the atmospheric CO2 increase is due to human activities? One answer often given (and the one I often use, too) is that since we emit twice as much as is […]

Climate Change Polls Are like the Weather: Everyone Likes to Talk About it.

Polls are interesting tools for persuasion but their validity depends on sample size and how the questions are asked. Most polls on issues that concern Americans put the environment near the bottom. While people may express concern about climate change, it is not what concerns them the most and it is less of a concern […]

Wikipedia Page on Propaganda Techniques Uses 97% Meme

If 99 billion mouths agree, shouldn’t you? Oh, this is too rich. I’ve blogged before on how global warming alarmists use all of the standard propaganda techniques to convince the not very super-sophisticated masses, using Al Gore’s own words. Well, it turns out the “97% of all scientists agree” meme is being used as an […]

The Magic of Models

A study recently published in the journal Nature Climate Change has gained a lot of attention in the environmental community and mainstream media—National Geographic for example. According to the study, the Keystone XL pipeline could produce four times more greenhouse gases than the State Department estimated in its final review in January. Since the study […]

As The Global Warming ‘Pause’ Continues Scientists Make More Dire Predictions

Global warming has been on hiatus for nearly the past two decades, according to global temperature records — and new research predicts this so-called “pause” in warming could last another decade or so.

Climate change ‘secrets’ recovered from bottom of Greenland lake

Researcher and project leader, Craig Frew said: “There are less than 100 years of detailed observations of climate available on a global scale, so to reconstruct a more comprehensive timeline of change over thousands of years, one of the things we can look at are proxy records of glacier variability. … To have confidence in climate models that are designed to predict future climate we have to be able to test and constrain them using instrumental or proxy records.”

Senior Meteorologist Demolishes, Mocks Alfred Wegener Institute Claims Of “Unprecedented Antarctica Ice Loss”

Measurements in Antarctica show a secular cooling trend. The exception is the Antarctic Peninsula and a part of West Antarctica (approx. 1% of the Antarctic area). In 2010 a new all-time record cold was measured: -93.2°C. The sea ice floating around Antarctica reached “100-year record” daily highs in 2014. With these observations, how anyone could conclude there has been a “record ice sheet retreat” remains a secret of the AWI.
