In Case You Were Worried About This…

Anthony Watts at wattsupwiththat is reporting today:

A new Policy Brief from The Heartland Institute shows there is no evidence of acceleration in the rise of global sea levels since the 1920s and concludes the U.N. Intergovernmental Panel on Climate Change’s (IPCC) concerns over this issue is “without merit.”

The Policy Brief, titled “Global Sea Level Rise: An Evaluation of the Data,” authored by Dr. Craig Idso, chairman of the Center for the Study of Carbon Dioxide and Global Change, Dr. David Legates, professor of climatology in the Department of Geography at the University of Delaware, and Dr. S. Fred Singer, is taken from a chapter of Climate Change Reconsidered II: Fossil Fuels, a report fromthe Nongovernmental International Panel on Climate Change (NIPCC).

According to IPCC’s Fifth Assessment Report, “it is very likely that the rate of global mean sea level rise during the 21st century will exceed the rate observed during 1971–2010 for all Representative Concentration Pathway (RCP) scenarios due to increases in ocean warming and loss of mass from glaciers and ice sheets.”

However, Idso, Legates, and Singer argue “sea-level rise is a research area that has recently come to be dominated by computer models. Whereas researchers working with datasets built from long-term coastal tide gauges typically report a slow linear rate of sea-level rise, computer modelers assume a significant anthropogenic forcing and tune their models to find or predict an acceleration of the rate of rise.”

…Instead of accelerated sea-level rises, the authors find “the best available data” shows “evidence is lacking for any recent changes in global sea level that lie outside natural variation.” They point out that if the negative effects of the claimed accelerated rise in sea level, such as a loss of surface area, were to be visible anywhere, it would most likely be in the small islands and coral atolls in the Pacific Ocean. However, research indicates many of these islands and atolls are actually increasing in size. Simply, they are “not being inundated by rising seas due to anthropogenic climate change.”

Fears of an accelerated rise in sea levels caused by anthropogenic climate change are misplaced and overblown. Further, this fearmongering should not be used by policymakers in coastal states and cities to advocate for policies that would seek to limit or eliminate carbon dioxide emissions.

No, we are not all going to drown in five years because of sea-level rise. Some politicians are screaming ‘the sky is falling’ because they believe it will get them the votes of young people who are not scientifically schooled. The earth’s climate is cyclical, we are in a cycle. There will be another cycle. We need to do what we can to limit pollution, but in the end, we are not important enough to make a significant difference. Pride is one of the things the fuels the extreme environmental movement.

If You Don’t Like The Data–Change It!

The Daily Caller posted an article yesterday about the latest numbers released (make that changed) by the National Oceanic and Atmospheric Administration (NOAA) about temperatures in America’s corn belt last summer.

The article includes two charts–one of the actual temperature data and one of the data after NOAA ‘adjusted’ the numbers:

These are the charts:

A picture is worth a thousand words.

The article reports:

Meteorologist Anthony Watts has also caught NOAA changing the temperature record. For two years, NOAA claimed that July 2012 was the hottest month on record — that is, until it quietly adjusted the data so that July 1936 was the hottest month on record.

“Two years ago during the scorching summer of 2012, July 1936 lost its place on the leaderboard and July 2012 became the hottest month on record in the United States,” Watts wrote. “Now, as if by magic, and according to NOAA’s own data, July 1936 is now the hottest month on record again. The past, present, and future all seems to be ‘adjustable’ in NOAA’s world.”

Generally speaking it is very easy to lie with statistics–you can make them say anything you want them to say. However, it is really easy to lie with statistics when you arbitrarily change the numbers. That seems to be what is going on with NOAA.

The Coming Ice Age

On Friday, Anthony Watts posted the graph below on his WattsUpWithThat website.

“Data adapted from ‘The Laurentide and Innuitian ice sheets during the Last Glacial Maximum’ by A.S. Dyke et. al., which was way better than the sequels ‘The Laurentide and Innuitian ice sheets during the Last Glacial Maximum: The Meltdown’ and ‘The Laurentide and Innuitian ice sheets during the Last Glacial Maximum: Continental Drift’.”

The bottom line here is simple–we are more at risk from global cooling than from global warming. Before we panic, we might also consider that as of yet we haven’t come up with an accurate computer model that correctly predicts long term trends in weather. Weather is the result of all sorts of things–carbon levels, sun spots, ocean temperatures, etc. Even at that, we really don’t know which of these things exerts the greatest influence or how they interact. Generally speaking, we need to do everything we can to keep the planet clean, but we need to balance that effort against the needs of the people who live on earth.
