A new study on climate change says |
| [00:02.22] |
catastrophic 4 degree rise in global temperature |
| [00:05.12] |
is increasingly likely to occur within many people's lifetimes. |
| [00:08.74] |
The studies have been compiled |
| [00:10.46] |
by one of the world's leading research bodies |
| [00:12.75] |
monitoring climate change, |
| [00:14.18] |
the Hadley Centre in Britain. |
| [00:15.76] |
Paul Harper reports. |
| [00:17.08] |
This latest prediction from the Hadley Centre |
| [00:19.68] |
brings the prospect of devastating change much closer. |
| [00:22.78] |
He challenges the assumption |
| [00:25.02] |
that severe warming is a threat only for future generations. |
| [00:28.69] |
A four degree average temperature rise by the 2050s |
| [00:33.01] |
would bring increases of 10 degrees or more in some areas |
| [00:36.41] |
such as the Arctic and Africa. |
| [00:38.20] |
It could mean a sharp decline in rainfall in some areas, |
| [00:41.66] |
flooding in others and extinction |
| [00:44.31] |
of about half of all the world's animal and plant species. |
