How can we 'solve' climate change ?

The UN climate change panel has been considering some unorthodox ways to tackle global warming.
With the IPCC climate change report indicating a 95% likelihood that human activities are the dominant cause of global warming, scientists have been attempting to find ways to counteract the effects and to reduce carbon dioxide emissions.

Aside from the more traditional solutions such as reducing pollution and switching to greener methods of transportation and power generation, researchers have come up a few alternative ideas, many of which sound like something out of a science fiction movie.
Seeding clouds with salt to promote water droplet formation, sowing the ocean floor with iron to stimulate the growth of carbon absorbing plankton and spraying sulphate particles in the stratosphere to reflect the sun's radiation are some of the more outlandish concepts being suggested.

Concerns have understandably been raised with regard to these countermeasures because some of them, especially spraying aerosols, could cause more problems than they solve.

Why should we *want* to "solve" climate change? The climate has been changing since the birth of our planet. The only constant in the climate is that it is always changing. The question itself shows the ludicrious assumption on which the entire political "global warming" scam is based, namely that a) the climate is naturally stable and b ) can be controlled by us like an airconditioner.

Some talk show happened to mention that despite predictions, a person entering his senior year of high school this year has lived his entire life without any global warming.

The definition of "global warming" is human-caused warming. The temps go up and down, but with human-caused warming added in, they go a little higher and they don't go down as far, but they still go up and down... [More]

Some talk show happened to mention that despite predictions, a person entering his senior year of high school this year has lived his entire life without any global warming. A high school grad this year would have been born in 1995. In 1995, temps were still heading strongly upward. So that person lived through three years of VERY rapid warming. Temps started upward again in 2005, but slower. Since then, they have trended slowly upward. So that high school grad has seen something like three or four all-time highs in their lifetime. Doug

The definition of "global warming" is human-caused warming. Pffft..... keyboard! Gee, now THAT is convenient, isn´t it! So, you postulate a claim, and then bend the facts to suit it. How do we call this? The "non-scientific method"?? The Catholic Church would have totally agreed with your deep thought, just a couple of hundred years ago. "The definition of earth is a disc." And if it is not a disc, it is still a disc! Good grief...

Gee, now THAT is convenient, isn´t it! So, you postulate a claim, and then bend the facts to suit it. How do we call this? The "non-scientific method"?? The pertinent question is whether or not that human-caused component is zero. When we take out the variation from every source we can think of, except humans, there's still an upward trend in the data. When that is correlated with temps, it disappears. What would you conclude?

Plant more trees and create forests in desolate area's might be a start.

Plant more trees and create forests in desolate area's might be a start. That's a good start, but it's not enough. Forests have a finite limit on the amount of CO2 they can sequester. And, we're running out of places to replant. That is reflected in seedling sales by the state nurseries. There are still a considerable number of odd areas and a few small fields that aren't really workable for agriculture, but once most of those are planted, then what? Under the Conservation Reserve the US is planting farmland, but that only carries to ten-year contract. When the rental payments run out, most fa... [More]

Stop using the oceans as a garbage dump and stop overfishing with those huge nets that grab everything up off the ocean floor would be a good start. There are so many dead zones in the ocean now. Ocean deserts, you could call them, where nothing living exists. Without living, breathing oceans, may as well kiss this world goodbye.
