‘Loss of wildlife’
In a statement calling for action to cut carbon emissions, institutions said evidence for “dangerous, long-term and potentially irreversible climate change” was growing.
Global carbon dioxide levels have continued to rise, Arctic summer ice cover was lower in 2007 and 2008 than in the previous few decades, and the last decade has been the warmest on average for 150 years.
The best thing we could do is to prepare for the worst. Build better flood defences in vulnerable areas Lee, Bracknell
Persistent drought in Australia and rising sea levels in the Maldives were further indicators of possible future patterns, they said.
They argue that without action there will be much larger changes in the coming decades, with the UK seeing higher food prices, ill health, more flooding and rising sea levels.
Known or probable damage across the world includes ocean acidification, loss of rainforests, degradation of ecosystems and desertification, they said.
In 2007, the Intergovernmental Panel on Climate Change (IPCC) warned that the world faced more droughts, floods, loss of wildlife, rising seas and refugees.
But Professor Julia Slingo, chief scientist of the Met Office, Professor Alan Thorpe, Nerc’s chief executive, and Lord Rees, president of the Royal Society, said cutting emissions could substantially limit the severity of climate change.

Prof Slingo told BBC Radio 4′s Today programme the importance of the statement was that “it emphasises that whilst global mean temperature changes may not sound very large, the regional consequences of those are very great indeed”.
She said: “As the inter-governmental panel on climate change stated very clearly in 2007, without substantial reductions in greenhouse gas emissions we can likely, very likely, expect a world of increasing droughts, floods, species loss, rising seas [and] displaced human populations.
“What this statement says very clearly is that some of those things, whilst we can’t directly attribute them at the moment to global warming, are beginning to happen.”

Carbon dioxide is probably the most important of the greenhouse gases as it accounts for the largest proportion of the 'trace gases' and is mostly responsible for the greenhouse effect.
ReplyDeleteI agree with you. But it is not the only one... what do you think?
ReplyDeleteI think that our primary aim should be a shift to alternative forms of energy. There are rumors, for example, that though car companies have already the necessary technology to produce economically efficient electric cars, they are forced to slow down...
