Need to focus on CO2 + MH4 having a 25 X more detrimental effect than CO2 + biomass MH4 power generation to replace landfill thus converting MH4 to energy. High investments in solar, eolic and oceanic generation. 50% CO2 reduction by 2050 inadequate. Kyoto replacement in 2012 must drive this change.

developed countries do ride the climate change, not the sun!
what we do is acelerate the process, which will last for years if it happend naturally.
who does pay you stephanie?

If the models are wrong Kyoto and carbon sequestration would be really dumb (50% more coal to stick a fertilizer underground). Regulating co2 output is like squeezing a balloon, we will constantly be dealing with unintended consequences, excessive regulation and very expensive solutions.

It is extremely unethical and inhumane to ask the developing nations to share the burden of greenhouse control for two very simple reasons: 1) the current high level of greenhouse gas is almost entirely due to the accumulation of emissions of rich nations over the last century.

2) the current rate of emission for rich nations on a per capita basis is still more than 5 times more. Cutting emission is simple economics: you have to pay for the extra cost, which should be borne by those who are responsible, not the poor and innocent!!!

Rebecca you are right ! But developed nations should take the the Upper Hand.

Dr. M.A. Sabur, Riyadh, K.S.A

Here in the UK we have 1% (60million) of the world's population (6,000million) but produce 2% of the world's emissions of greenhouse gases.
Only when we reduce our emissions to the world average will we have the right to lecture others.
We're not a poor country, just greedy !

Peter Hooper, Windsor, UK

Why are our leaders so hell bent wasting trillions of OUR money on a problem that DOES NOT EXIST?Climate change is NATURAL & CYCLIC and driven by the SUN! When will our political dummies take notice?When the new ice sheets reach London&New York? Its funnyfarm crazy folks & we are all in for a shock!

Stephanie King, larnaca, Cyprus

the most practical solution to reduce emission in the long term for controlling climate change is the developed nations in conjunction with developing ones ,in my experience.
