Increased scrutiny of climate catastrophists' claims is leading to panic among the promoters of global warming hype. Rather than attempting to counter mounting evidence that global warming—at least as defined by the IPCC and its supporters—is not a valid scientific theory, a number of leading catastrophists have issued a public call to climate scientists. Their plea? Further dumbing down climate science by using a simplified “common climate language” to “advance the public's decision-making capacity.”
Currently the sun is in one of its least active periods since the Maunder Minimum, during the depths of the Little Ice Age. A quiet Sun comes along every 11 years or so—it's a natural part of the sunspot cycle, discovered by German astronomer Heinrich Schwabe in the mid-1800s. What does this have to do with global warming and climate change? It just may be why things keep getting colder as climate activists tell us Earth is melting down.
A recent article in the journal Science has provided a new, detailed climate record for the Medieval Climate Anomaly (MCA), also know as the Medieval Warm Period. It was the most recent pre-industrial warm period, noted in Europe and elsewhere around the globe. The researchers present a 947-year-long multi-decadal North Atlantic Oscillation (NAO) reconstruction and find a persistent positive NAO during the MCA. The interesting thing is that the MCA had basically been removed from the climate record by Michael Mann's infamous “hockey stick” history graph that was adopted by the IPCC a decade ago.
The current hot phrase bandied about by talking heads and parotted by news pundits is “tipping point.” We are told that the climate may be near a tipping point, if it has not crossed one already, and that can't be good. But what is a tipping point, where do they come from and how can we identify one when we see it?
Here are some interesting climate related tidbits from the science news feeds; food for thought in the new year. First, researchers at the University of Oregon have discovered evidence linking the disappearance of North American megafauna, the Clovis people and the onset of the Younger Dryas period to a comet impact. For years scientists have blamed the disappearance of the American Mammoth, Mastodon, saber toothed cats and other large land animals on human predation or climate change.
