Radioactive carbon dating for kids

Asked by MPs on the committee whether the European Emissions Trading scheme was insufficient to meet these targets, Humphrey Cadoux-Hudson, managing director of new nuclear build at EDF, agreed.Schemes to reflect sun or absorb CO2 warrant study - to sort the real science from the science fiction Emissions of carbon dioxide are rising even faster than was expected, and if they continue to do so we are on track for global temperatures which are likely to be 4C higher, or even more, by 2100, with disastrous consequences.

Researchers in Canada are reporting for the first time that high mercury levels in certain Arctic seals appear to be linked to vanishing sea ice caused by global warming.• Threatened site is one of the most efficient • Proposed atomic plant backed by government One of the oldest and most efficient wind farms in Britain is to be dismantled and replaced by a nuclear power station under plans drawn up by the German-owned power group RWE.The site at Kirksanton in Cumbria - home to the Haverigg turbines - has just been approved by the government for potential atomic newbuild in a move that has infuriated the wind power industry.In a world were consumption becomes more calculated, the value of design is critical.Not only must the function of any new object should be validated, its cultural, economic and social impact must be accounted for, whether it has a heavy or shallow carbon footprint.Extensive climate change is now affecting every form of life in the Arctic, according to a major new assessment by international polar scientists.

In the past four years, air temperatures have increased, sea ice has declined sharply, surface waters in the Arctic ocean have warmed and permafrost is in some areas rapidly thawing.

In addition, says the report released today at a Norwegian government seminar, plants and trees are growing more vigorously, snow cover is decreasing 1-2% a year and glaciers are shrinking.

Scientists from Norway, Canada, Russia and the US contributed to the Arctic monitoring and assessment programme (Amap) study, which says new factors such as "black carbon" – soot – ozone and methane may now be contributing to global and arctic warming as much as carbon dioxide.

There are those who simply don't want to accept the evidence, because it is too much to bear, or because it threatens aspects of their lives that they don't want to change.

These are by far the most numerous, and account for most of those whose comments will follow this post. Denial is most people's first response to something they don't want to hear, whether it is a diagnosis of terminal illness or the threat presented by the rise of the Axis Powers.

The climate situation may be even worse than you think.
