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.

Is Global Warming Causing More Snowstorms?

It has become axiomatic (and fashionable) that any change we see in nature is caused by global warming climate change. Global warming was going to make snow a thing of the past. Until someone looked out the window and decided global warming causes more snow. The epic Buffalo, NY storm this week was still in […]

What’s the Climate Pledge Worth? Absolutely Nothing

It is amazing that anyone could take this agreement seriously. It clearly demonstrates that clear thinking is a victim of zealotry. The agreement is analogous to a race between two high performance cars where the driver of one agrees to run on four cylinders. Little doubt about who wins. China, which is building a new […]

Will Happer, Princeton’s Galileo

Paul Budline of Princeton, New Jersey, writes: “I do documentary/video work for a living and took my camera to Princeton University last week to interview Will Happer, the physicist and climate skeptic. The resulting 4-minute video, which I put on YouTube Saturday, has been a big hit at enviro sites and FB, but it still […]

Our Snookered President

The applause for the climate agreement between President Obama and China ought to be an embarrassment.  The President was snookered and apparently doesn’t know.  China promised to cap emissions in 16 years and the President promised to increase emission reduction actions now.  What kind of deal is that?  It’s a bad economic and environmental. China’s […]

European Climate Institute EIKE: European Winters Show Clear Cooling Trend Since Hansen’s 1988 Testimony

Today, according to the European Institute for Climate and Energy (EIKE) here, data from the DWD German national weather service shows that winters in Germany have been cooling significantly and in parallel with those in Austria for close to three decades – despite rising CO2 emissions. If Co2 has a warming effect, it hasn’t been seen in Central Europe since James Hansen testified before Congress in 1988!

No Change In New Zealand Temperature For 60 Years

Temperatures in New Zealand have been plummeting since 1998, and are cooler now than they were 60 years ago.

Sea spray represents complex chemistry with big effects on climate

Take in a deep breath of salty ocean air and more than likely, you’re also breathing in naturally occurring sea spray aerosols. But, there’s much more in each of those tiny bursting “bubbles” than salt. They’re also bursting with ocean life, from bacteria to phytoplankton—even viruses. Because sea spray aerosols seed clouds, they affect the climate.
