A recent headline caught my eye, “Wind farms make climate change WORSE: Turbines actually heat up local areas.” This appeared in the London, England based Daily Mail. The article reported that air temperatures around four of the world’s largest wind farms had incresed over a decade by 0.72 degrees Celsius ( about 1.3 degrees Fahrenheit).

Today is Earth Day and it seems appropriate to include an article about climate change. Last week a study was published in Nature Geoscience showing that some areas of the Himalayas were gaining ice steadily. The study compared data collected on the Space Shuttle Endeavour in 2000 with the French SPOT5 satellite data collected in

If there is a canary in the coal mine of climate science, the temperature of the ocean is our best early warning system that something is amiss. As the atmosphere warms and intermixes with the ocean surface some of that heat is transferred to the water. That high heat capacity makes the ocean an ideal

Does the recent warm spell over the eastern half of North America reflect climate change induced by increased greenhouse gases? When Europe experienced an extreme heat wave in 2003, two scientists at the Potsdam Institute for Climate Impact Research began a study to see if that event could be related to global warming. Dim Coumou

For the last two weeks here in Toronto the temperature has been abnormally warm. Today, March 19, 2012, we will see late May, early June daytime high temperatures. This is the second winter in the last three to produce a winter that by Toronto standards can only be called balmy. Which brings me to the

When I was a younger man working in the world of information technology I was an avid reader of James Martin’s books on computers and telecommunications. Recently I came across one of his books of which a part is published online. Entitled, “The Meaning of the 21st Century,” it outlines 16 challenges that humanity faces

In a blog devoted to 21st century technology why are we discussing climate change? Because if climate is changing, and the evidence strongly suggests that, it will impact the planet in this century and beyond. Our response to climate change will play a critical role in determining new technologies that we apply to counter changing

Climate change as a result of human activity on Earth is a science that has more and more taken on credibility as we track rising global temperatures, ozone depletion, vanishing polar ice, shrinking alpine glaciers, and extreme weather systems that are a departure from recorded meteorological history. Humanity has several choices. We can stay the
