Editor,

The U.N. surprisingly reduced one of its warming scenarios by .5 degrees Celsius when the opposite had been predicted. While saying the sea levels had increased over 50 years it didn’t mention that they were increasing almost as fast 90 years ago. Unexplained was how a natural warming of Earth ended the Little Ice Age in 1860, not man’s emissions. 

Man is a contributing cause to warming but not “the” cause. It is well documented that warming periods on Earth coincide with the sun’s cycles. The last major ice age 10,000 years ago deposited a 2 mile thick ice sheet on North America. And the Little Ice Age reduced carbon dioxide levels to such low levels that food crops had difficulty growing. It caused the starvation of millions. The co-founder of Green Peace, Patrick Moore, says we’re lucky that carbon dioxide has risen to safer levels as reflected in photos from space showing a much greener earth than in the 1960s. It is a scientific fact that temperatures on Earth and carbon dioxide are the lowest in 460 million years.

I’m for government investing in research, but not picking winners in green technology. I’m amazed that the hydrogen/solar cycle, which is by far the least expensive generating and storing technology, has hardly been mentioned in our news media. It’s almost as if Dems prefer the issue to a very feasible inexpensive solution.

The point is that whatever nature does re. global climate change, we keep adding to it! Whenever our contribution adds to nature’s peaks, we have trouble, like now! While we may not be able to change nature’s habits, we can, and should, control what we do in order not to aggravate the problem.

I agree. We should be good stewards of the environment.

With respect to CO2 emissions, there is wisdom in your statement, "... we can, and should, control what we do in order not to aggravate the problem." I feel replacing our reliance on fossil fuels with the development of practical alternatives is a positive step in that direction.

Last year, the United States was responsible for 15% of the world's CO2 emissions... we can bring that number down. However, what can be done about China and India's combined 40% of the world's CO2 emissions? Will we just have to wait until others on our planet recognize the harm they are doing to the environment?

Jorg

Good question, Ray! Although what we can do only has a minor impact on the overall problem, perhaps we could set a good example for the rest of the world, and be a leader?

Mr. Kahl – thanks for some inconvenient (for greenies) truths. Everyone knows the Earth will do what she does, independent of what some people think man is capable of doing to her. She was around long before us and she’ll be around long after us. In regards to your last sentence, my first impression is that Dems prefer to use this silly global warming thing as a cudgel to demand obedience to yet another false narrative. However I’ll ponder upon it as I take a long drive in my V-8 gas-powered car, return for a BBQ, and if I’m not too sleepy afterwards, wash my car, water my lawn, and do the laundry. Maybe fire up the old fireplace if the evening turns chilly.

Mr. Kahl,

You make a number of statements which I am not here to argue about even if I disagree with some of them. I will toss a couple of other items into the mix. As I understand it, the little ice age (LIA) was started by an unusually high number of volcanic eruptions around the 1300 which caused the more rapid cooling. The little ice age was not global, it was mainly in the northern Atlantic region of north America and Europe and had the coldest temps at different times for different regions. The difference from then to now is it was regional then and warming now is totally global.

As for the specific cause of the end of the LIA and warming now, there is little agreement as you say. There is a lot of agreement that a combination of volcanic activities, solar cycles, ocean currents etc. all contributed to the natural end of the LIA, however, the data doesn't seem to explain the current global warming. Sun cycles have been stable and solar activity has been somewhat quiet over the last 50 years but the warming has continued.

Taffy - an interesting observation that you pose. Since we don't seem to know why there is global warming why come up with all of these ludicrous measures to combat the unknown?

Tafhdyd

Dirk,

That is a fair question although I wouldn't call the measures ludicrous. You do what you think will work until you find out what does work. If you walk into the bathroom and see water leaking from the toilet do you turn around and say I don't know what is leaking and let it keep flooding the floor? Most people will put down a towel to stop the water from the rest of the house while they shut off the supply. Maybe it is a crack in the bowl, maybe a crack in the tank, maybe a bad connector to the tank, maybe a leaky valve. The point is you do something and then try to find the problem, you don't just walk away.

Dirk van Ulden

Taffy - an obvious water leak is not the same as an unknown source of global warming.

Thank you for your insightful comments. I would agree that volcanos are one of many natural variations effects on the climate that began and ended the Little Ice Age. But I think the sun's control of cloud cover on earth is the major prime mover of natural variation effects on earth. To say (which you aren’t) that man is 100% responsible for global warm is to ignore natural variation. If man is only responsible for 50% of global warming, modeled temperature projections would drop by half and show we are not in a climate crisis and have time to develop affordable green energy.

Tafhdyd

Mr. Kahl,

Thanks for your reply. We don't agree on things political but at least we can trade ideas on some things that are "not quite" as political.
