While looking at the weather maps yesterday I found an opportunity to measure the temperature effect of heavy rainfall in an extremely hot region during the peak of summer, with the sun at a high angle. Central Australia meets those … Continue reading →

One of my favorite science writers is Bob Berwyn, whose posts appear every few days in the Inside Climate News website (which also has many other good reporters besides Bob.)  Berwyn is special because of his uncanny knack for emphasizing … Continue reading →

Results of a major study covering the interaction between rising CO2 levels and tropical rain forest productivity have been published.  The study was conducted over a period of 21 years, with a good many significant variables taken into account.  The … Continue reading →

It’s midwinter at the North Pole and midsummer in the south. I want to save a record of how they compare on the weather maps, hoping to do so again in July when the seasons have reversed. The shape of … Continue reading →

Why are so many expert climate scientists deeply worried about “catastrophic” results from current trends of climate change?  You need to have read yesterday’s letter about the results of a survey of opinions of 92 individuals who were qualified authors … Continue reading →

What is the likelihood that the global average temperature increase—relative to pre-industrial—will remain less than1.5C? This is arguably the most important of all questions relevant to the future direction of climate change. There are a number of different ways to … Continue reading →

The globe is loaded with stunning temperature anomalies these days, with quite an array of hot and cold contrasts to the north of about 40 degrees of north latitude. This is typical of the mid-winter season. Note that south of … Continue reading →

The theory of sulfate aerosol cooling, which I have recently been writing about, is one that I find very persuasive. It involves a mechanism that is critical to the process, but it is almost impossible to understand why things should … Continue reading →

Another way to look at our commitment to future warming above 2C, even if there is a substantial lowering of CO2 and other emissions soon to come and no major increase in their concentrations.  Yesterday we reviewed a study from … Continue reading →

A new study provides strong support for James Hansen’s predictions related to the global temperature effects from aerosols created by sulfur dioxide emissions due to the burning of coal and oil.  Hansen’s views are summarized in his July Temperature Update, … Continue reading →
