NCA Quote: “Precipitation patterns are changing”
Reality: Precipitation patterns were never constant. Creating a crisis from the normal allows climate catastrophists to point to every abnormal bit of wet or dry as being “consistent with models” that predict one horrible outcome or another.
NCA Quote: “sea level is rising”
Reality: Yes sea level is rising, which it has done since the end of the last ice age. But the frequent claims and predictions of accelerating sea-level rise are not borne out in the data. In fact sea-level rise has slowed recently. One main-stream climatologist says this variation “makes the 21st century of sea level rise projections seem like unjustified arm waving.”
NCA Quote: “the frequency and intensity of some extreme weather events are increasing”
Reality: The latest report on the science from The Intergovernmental Panel on Climate Change and analysis provided by the adminstration’s own National Climatic Data Center conclude that there isn’t a case for extreme weather increases – no significant trends for floods, droughts, hurricanes or tornadoes.
NCA Quote: “In Arctic Alaska, the summer sea ice that once protected the coasts has receded”
Reality: Global warming is supposedly global. Global sea ice (Arctic and Antarctic) is above average and, for this time of year, it is at its highest level in 30 years, which is the third-highest on record.
The authors apparently do not think anybody is checking their statements or they couldn’t possibly think they would get away with this one:
NCA Quote: “It is notable that as these data records have grown longer and climate models have become more comprehensive, earlier predictions have largely been confirmed.”
Reality: The past 15 years have seen the climate model predictions stray farther and farther from actual temperatures (here and here). Last year, prominent climatologist, Hans von Storch, said, “If things continue as they have been, in five years, at the latest, we will need to acknowledge that something is fundamentally wrong with our climate models.” Maybe Professor von Storch needs four more years to be sure the models are wrong, but there are no grounds on which the models can be declared “confirmed.” Instead, the predictions are getting worse and worse.
