Tag: climate change

[def. dictionary.com]  a long-term change in the earth’s climate, especially a change due to an increase in the average atmospheric temperature: Melting glaciers imply that life in the Arctic is affected by climate change. … Foremost among them is the role of birth control in dealing with climate change.

[added comments] The above appears to be an overly simple definition of climate change and the last sentence is open to extensive discussion.  There is much more to climate change than temperature.  There is wind, precipitation, humidity, atmospheric pressure, and other elements.  Also, there is nothing unusual about climate change, because the climate is constantly changing.  Climate is simply average weather.  What that is depends on the averaging period.  Some say that at least 30 years of measurements are required to compute climatic averages, but that is not necessarily correct.  There are good reasons to consider 60 years of measurements due to the 60-year Pacific Decadal Oscillation (PDO).  The limiting factor in computing climatological averages is the amount of measurement data available.  Generally, there is no more than 100 to 150 years of data unless proxy data are used.  Regardless, the climatological average will be different for each different averaging period.  Consequently, we must conclude that we really do not have sufficient data to know what the climatological averages are not to mention how they are changing.

Study: Sea Level Rise Revised Downward

“Satellite snafu masked true sea-level rise for decades”
“Revised tallies confirm that the rate of sea-level rise is accelerating as the Earth warms and ice sheets thaw.”

When I read that, I (like everyone else) assumed that corrections to the satellite sea level data since 1993 have now led to a revised trend toward faster (not slower) sea level rise. Right? Continue reading “Study: Sea Level Rise Revised Downward”

Supposed threats to coastal military installations ignore science

By Bob Endlich

“Data from CO2 measuring stations and from the Sewell’s Point and all other tide gages may clearly refute these assertions, but NPR and its colleagues will not change their minds.”

“The Sewell’s Point tide gage shows that the rate of sea level rise has not changed since the gage was installed in 1927, and is unchanged from our use of fossil fuels. It’s time to base our policies on sound science, instead of manmade global warming fiction and scare stories.”

National Public Radio’s March 31 “Morning Edition” program carried a “news” story claiming that rising seas threaten a number of U.S. coastal Continue reading “@NPR Bungles Sea Level Rise Story”

Audubon Goes over the Edge (Jan/Feb 2016 issue) promotes anti-science alarmism)

[This is a reprint of an article published by MasterResource.Org in 2016.  We have included it as an archive post by CASF member, Bob Endlich]

By Bob Endlich — February 4, 2016

“Audubon’s equivocal policy on wind power ostensibly calls on wind energy developers to consider planning, siting, and operating wind farms in a manner that avoids bird carnage and supports ‘strong enforcement’ of laws protecting birds and wildlife. On the other hand, the same Audubon policy speaks about ‘species extinctions and other catastrophic effects of climate change’ and ‘pollution from fossil fuels’.”

The cover of the January-February 2016 issue of Audubon Magazine  proclaims: Arctic on the Edge: As global warming opens our most critical bird habitat, the world is closing in. In reality, it is the magazine’s writers and editors who have gone over the edge with their misleading reports on the Arctic.

This magazine is so awash in misstatements of fact and plain ignorance of history, science, and culture, that Continue reading “Audubon Goes over the Edge (Jan/Feb 2016 issue) promotes anti-science alarmism)”

In science, one likes to have more examples than theories. – Dusan Djuric

Those words, spoken whimsically about cosmology, apply to climate science as well. The theory of the sensitivity of climate to the radiative SFCTforcing imposed by a doubling of carbon dioxide suffers from a lack of observed, repeatable examples. Paleo-climate studies carry with them the uncertainty of the proxy data and unmeasured assumptions on which they are based. Studies regarding the forcing from volcanoes and other transient events may not be repeatable for some time. However, Lindzen et. al. 1995 (link ) and Ramanathan and Inamdar in Frontiers of Climate Modeling, 2006 (link ) each have pointed out that the seasonal variation of earth temperature is quite large and possibly a surrogate for climate change. With this in mind, I set out to determine how the seasonal variation Continue reading “Seasonal Radiative Response”

History falsifies climate alarmist sea level claims

Seas have been rising and falling for thousands of years – without help from the EPA or IPCC

Seas have been rising and falling for thousands of years – without help from the EPA or IPCC

Guest essay by Robert W. Endlich

Sea levels are rising rapidly! Coastal communities are becoming more vulnerable to storms and storm surges! Small island nations are going to disappear beneath the waves!

Climate alarmists have been making these claims for years, trying to tie them to events like “Superstorm” Sandy, which was below Category 1 hurricane strength when it struck New York City in October 2012, and Typhoon Haiyan, which plowed into the low-lying central Philippines in November 2013.

For alarmists, it does not seem to matter that the strength and frequency of tropical storms have been decreasing in recent years, while the rate of sea level rise has fallen to about seven inches per century. Nor does it seem to matter that the lost lives and property have little to do with the storms’ sheer power. Their destructive impact was caused by their hitting heavily populated areas, where governments had not adequately informed Continue reading “History falsifies climate alarmist sea level claims”
