Is there any irrefutable evidence that any action by man will have a positive effect on climate change?

If there is no firm evidence, which I don't think has really ever been discussed - so fiery has been the argument on climate change itself - then any money to be spent on just 'hope' should be kept to help repair the economy.

Precisely, ttbn.

The entry-level questions are: what is irrefutably happening (virtually nothing), what could we do about ameliorating adverse impacts (virtually nothing) and what would such amelioration cost (trillions, for no result).

Another anti Climate Change thread. When the oceans cool and Glacial ice stops melting you may have a chance of denying climate change is happening.

Co2 at 400 parts / million did not get there on its own. So just another rant to appease a handful on Conservatives that can not have any change what so ever.

the climate has been changing every day for millions of years.

do you really think paying a carbon tax on the air we breathe to the international banksters is going to the improve the environment?

why are the left wing elites so desperate to make the 1% of the 1% even richer?

No but there is plenty of evidence that we can have a very negative effect on the atmosphere and climate.

1 Adding more CO2 to the atmosphere will increase surface temperatures.

2 Adding CFCs to the atmosphere destroys ozone at altitude and further enhances surface warming.

4 Surface global warming causes a dramatic net loss of ice, reducing the earths albedo and amplifying the warming further.

5 Warming oceans amplify the intensity of tropical storms and further enhances global warming.

6 A warming climate moves climate zones towards the poles thus increasing the size of desert zones north and south of the tropics of Capricorn and cancer.

7 Burning fossil fuels produces photo chemical smog and harmful particulates.

8 Activities by man has added incredible amounts of dust to the atmosphere, the consequences of which are probably bad.

Calwest. Succinct, clear and hitting the nail precisely on the head. Well said!

doog. "Co2 at 400 parts / million did not get there on its own". So, the millions of years wherein CO2 fluctuations have greatly exceeded these levels, (more 'up' than down thank heavens), at 270/280 ppm extinguishes plant life; so where did those fluctuations come from? ie, well before mankind came down from the trees.

ttbn. That's twice today that I completely concur with your comments! spooky innit?
