Since the myth won’t die, progressives need to be armed with the facts. I am no Bishop or Priest, but here goes:
Mars does appear to be experiencing short-term regional warming, not long-term global warming, as the climate scientists of Realclimate.org have explained.
Jupiter is not experiencing global warming, but it is poised to experience regional climate change, “getting warmer near the equator and cooler at the poles,” as a U.C. Berkeley scientist noted last year.
As for Pluto, an MIT article explains “Pluto’s orbit is much more elliptical than that of the other planets, and its rotational axis is tipped by a large angle relative to its orbit. Both factors could contribute to drastic seasonal changes.”
One of the scientists involved in the research explained, Pluto’s warming was “likely not connected with that of the Earth. The major way they could be connected is if the warming was caused by a large increase in sunlight. But the solar constant–the amount of sunlight received each second–is carefully monitored by spacecraft, and we know the sun’s output is much too steady to be changing the temperature of Pluto.” And it is too steady to be changing the temperature of the Earth, for that matter: “The sunspot record and neutron monitor data,” as Realclimate.org explains, “show that solar activity has not increased since the 1950s and is therefore unlikely to be able to explain the recent warming.
This last point is key. The causal link between the Earth’s warming and the alleged warming of other planets would have to be solar activity. But a recent study has shown that solar activity, including cosmic rays, are not responsible for recent planetary warming. The study (subs. no longer req’d) concluded:
Here we show that over the past 20 years, all the trends in the Sun that could have had an influence on the Earth’s climate have been in the opposite direction to that required to explain the observed rise in global mean temperatures.
What is most sad to me is the ease with so many people believe the entire scientific community somehow failed to examine the contribution of the sun to recent global warming.
