Playing God with the Weather Will Outdo Mother Nature’s Worst Nightmares

Could Lead to Severe Cooling

 By Dr. Tim Ball 


13 Apr 09 - (Excerpts) - Actions without thought or concern for the consequences are the pattern of the day as political agendas trump facts or logic. Consider the dangerous and baseless proposal to offset global warming by adding particulates to the atmosphere. It was in the news as a strategy, albeit a last resort, from a member (John Holdren) of the Obama administration.

If done it will trigger severe cooling, including global harvest failures and much more severe weather. It is a much greater threat than warming,

Even as a last resort the proposal underscores complete lack of knowledge of the science and the consequences of such actions. Simple theory says particulates reduce sunlight reaching the ground, creating a cooler surface and cooler air, because the ground heats the air.

The world is (already) cooling so to induce more cooling on the basis of a debunked hypothesis will create bigger problems than if warming occurs. Cooling is a much greater problem for flora, fauna and humans. There is an historic and natural example of what happens when a singular event exacerbates cooling.

In 1992, we organized a conference in Ottawa Canada to analyze the climate impacts of the Indonesian volcano Tambora. It was the largest eruption in historic times and considered the cause of the history changing record cold year of 1816, known as the The Year Without a Summer.”

John Eddy, who put the sunspot issue in the public arena with a 1977 Scientific American article titled “The Case of the Missing Sunspots,” presented the keynote paper.

He identified the cooling associated with the lack of sunspots from 1790 to 1830 known as the Dalton Minimum. This meant global temperatures were falling before volcanic cooling was added in 1815. Clearly the cooling due to the volcanic dust injected into the atmosphere amplified a cooling trend.

Current cooling is expected to approximate cool conditions similar to those between 1790 and 1830.

Adding particulates would exacerbate the cooling and trigger a year like 1816. The impact of that year are well documented in the Ottawa publication, but also in J D Posts’ “The Last Great Subsistence Crisis in the Western World” and Stommel and Stommel’s “Volcano Weather.” Harvest failures alone would be devastating for a world with such limited stockpiles. Consider the impact of biofuels on world food supplies.

Despite this politicians demonstrate their lack of knowledge of the science by proposing to play God. Maybe they should wait until there is enough space debris to block the sun and cause cooling.
