Essentially, by 2050 we need all activities outside agriculture to be near zero carbon emitting if we are to stop carbon dioxide levels in the atmosphere growing
First, climate change is the greatest long-term threat faced by humanity. It could cause more human and financial suffering than the two world wars and the great depression put together. All countries will be affected, but the poorest countries will be hit hardest. Secondly, the costs of inaction far outweigh the costs of action.
The scientific evidence is now overwhelming: climate change presents very serious global risks, and it demands an urgent global response.
Adaptation is the only means to reduce the now-unavoidable costs of climate change over the next few decades
Adaptation is a vital part of a response to the challenge of climate change
Adaptation can efficiently reduce the costs of climate change while atmospheric concentrations of greenhouse gases are being stabilised
Climate change will affect the basic elements of life for people around the world - access to water, food production, health, and the environment. Hundreds of millions of people could suffer hunger, water shortages and coastal flooding as the world warms.
Greenhouse gas emissions: Ultimately, stabilisation - at whatever level - requires that annual emissions be brought down to more than 80% below current levels
Climate change represents the greatest and widest-ranging market failure ever seen
Dangerous climate change... It's important not to be alarmist but it is very important to be alarmed
We're putting 70 million tonnes of pollution into the atmosphere every day, trapping an enormous amount of extra heat from the sun inside the earth's atmosphere. It's threatening to push the planet past a tipping point beyond which climate change would be difficult to stop
Although reducing human emissions to the atmosphere is undoubtedly of critical importance, as are any and all measures to reduce the human environmental "footprint", the truth is that the contribution of each individual cannot be reduced to zero... If we believe that the size of the human "footprint" is a serious problem (and there is much evidence for this) then a rational view would be that along with a raft of measures to reduce the footprint per person, the issue of population management must be addressed.
Climate change: It's here. If we don't react, war, pestilence and famine will follow close behind
Climate change: We have never faced a more critical time on our planet
Margaret Thatcher was the first political leader in any major country to warn of the dangers of climate change
We need to develop the new green industrial revolution that develops the new technologies that can confront and overcome the challenge of climate change; and that above all can show us not that we can avoid changing our behaviour but we can change it in a way that is environmentally sustainable.
If what the science tells us about climate change is correct, then unabated it will result in catastrophic consequences for our world.
Climate change is probably the greatest long-term challenge facing the human race.
The probability that we face global warming caused by fossil fuels is now so overwhelming that it is legitimate to doubt the motives of those who deny it
Can nine billion people be fed? Can we cope with the demands in the future on water? Can we provide enough energy? Can we do it, all that, while mitigating and adapting to climate change? And can we do all that in 21 years time? That's when these things are going to start hitting in a really big way. We need to act now. We need investment in science and technology, and all the other ways of treating very seriously these major problems. 2030 is not very far away
Everybody talks about population growth and its disastrous effect on climate change, food security and resource depletion, but nobody does anything about it
It is environmental illiteracy and a complete lack of forward thinking to ignore the need to halt and then reverse population growth in the context of climate change, travel congestion, unaffordable housing, and resource depletion
CO2 emissions have been increasing, but the rise in air temperature stopped around 2001. Climate change is due in large part to naturally occurring oscillations.
It used to be controversial whether smoking caused lung cancer, it used to be controversial whether HIV caused AIDS. Now, there are a few mavericks who deny those things. In the case of climate change, I think the debate is going the same way in that there is a strong consensus that it is a serious matter.
Global warming causing climate change may be the ultimate issue that unites us all.
