"And it’s clear that Singer is not alone in his thinking. His most recent book, Unstoppable Global Warming — Every 1500 Years is on the New York Times bestseller list".
In a recent article in Le Monde, Singer laid out his arguments: “First, the climate is always changing — either warming or cooling – on time scales ranging from decades to millions of years. Nearly 20 ice ages have come and gone in the past two million years, controlled by predictable changes in Earth’s orbit and tilt of its axis,” Singer wrote. “Our present interglacial warm period is 12,000 years old and may soon end. Geological evidence has also uncovered a 1,500-year climate cycle, likely caused by the sun — and also unstoppable. On top of all this, we have irregular, unpredictable short-term fluctuations. Since 1979, weather satellites have shown a slight warming trend that is well within historical experience. How can we tell whether this recent warming is due to human influences, such as the rise in atmospheric greenhouse gases, or whether it is simply another natural fluctuation?
