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.

Climate Change is normal and natural and has gone on for millions of years without any help from the human race. The scaremongering now going on by the media, politicians and climate alarmists, is so utterly misguided to be nothing but tragic. That we have an End of the World scenario is Continue reading “It’s madness, madness, madness, there is no climate emergency”

About Recent Words from Richard Lindzen

Robert W. Endlich

We have posted on this forum two recent essays by Richard Lindzen, the first, The Imaginary Climate Crisis – How can we Change the Message? from Clintel, and the second, An Assessment of the Conventional Global Warming Narrative, originally from London’s Global Warming Policy Foundation. I presented my analysis of the high points of Lindzen’s essays, along with some comments to bring these topics home, especially to those

Emeritus MIT Professor Richard S. Lindzen

of us in southern New Mexico, and also, from the world of operational meteorology.

Here is a small, but hopefully representative, sample of some of Lindzen’s most important thoughts, and some comments.

Lindzen properly says:

“…the whole narrative is pretty absurd.”

and in his writing, he goes on to provide the data and his reasoning for why Continue reading “About Recent Words from Richard Lindzen”

A New Look at NOAA’s Alleged Cat 5 Strength for 2018’s Hurricane Michael

‘More evidence that Hurricane Michael was definitely NOT a Category FIVE storm at landfall.’

In late September 2022 Category Four Hurricane Ian struck southwest Florida bringing death and destruction to southwest Florida. Ian’s arrival and wind damage spurred me to take another look at when 2018’s Hurricane Michael struck the Panhandle of Florida, and NOAA’s 2019 declaration that Michael was a Category Five storm at landfall.

This is my new look at Hurricane Michael’s winds and NOAA’s 2019 report. Continue reading “A New Look at NOAA’s Alleged Cat 5 Strength for 2018’s Hurricane Michael”

The Imaginary Climate Crisis – How can we Change the Message?

Richard S. Lindzen
Professor Emeritus of Atmospheric Sciences, MIT

[This essay is a slightly extended version of a lecture delivered to a joint zoom meeting of the Irish Climate Science Forum and CLINTEL on March 31, 2021.]

For about 33 years, many of us have been battling against climate hysteria. We have correctly noted

The exaggerated sensitivity,

The role of other processes and natural internal variability,

The inconsistency with the paleoclimate record,

The absence of evidence for increased extremes, droughts, floods, wild-fires, and so on.

We have also pointed out the very real benefits of CO2 and even of modest warming.  And, as concerns government policies, we have been pretty ineffective.  Indeed our efforts have done little other than to show (incorrectly) that we take the threat scenario seriously.  In this talk, I want to make a tentative analysis of our failure.

In punching away at the clear shortcomings of the narrative of climate Continue reading “The Imaginary Climate Crisis – How can we Change the Message?”

Explaining Mauna Loa CO2 Increases with Anthropogenic and Natural Influences

Summary

The proper way of looking for causal relationships between time series data (e.g. between atmospheric CO2 and temperature) is discussed. While statistical analysis alone is unlikely to provide “proof” of causation, use of the ‘master equation’ is shown to avoid common pitfalls.  Correlation analysis of natural and anthropogenic forcings with year-on-year changes in Mauna Loa CO2 suggest a role for increasing global temperature at least partially explaining observed changes in CO2, but purely statistical analysis cannot tie down the magnitude. One statistically-based model using anthropogenic and natural forcings suggests ~15% of the rise in CO2 being due to natural factors with an excellent match between model and observations for COVID-19 related downturn in global economic activity in 2020.

Introduction

The record of atmospheric CO2 concentration at Mauna Loa, Hawaii since 1959 is the longest continuous record we have of actual (not inferred) Continue reading “Explaining Mauna Loa CO2 Increases with Anthropogenic and Natural Influences”
