Coral decline - due to climate change?
Coral growth in Australia's Great Barrier Reef has slowed to its most sluggish rate in the past 400 years. The decline endangers the species the reef supports, say researchers from the Australian Institute of Marine Science. They studied massive porites corals, which are several hundred years old, and found that calcification has declined by 13.3% since 1990. Global warming and the increasing acidity of seawater are to blame, they write in Science journal. Read the full story here. Miss M.

Global warming & humans
The rise in temperatures at Earth's poles has for the first time been attributed directly to human activities, according to a study. The work, by an international team, is published in Nature Geoscience journal. In 2007, the UN's climate change body presented strong scientific evidence the rise in average global temperature is mostly due to human activities. This contradicted ideas that it was a result of natural processes such as an increase in the Sun's intensity. At the time, there was not sufficient evidence to say this for sure about the Arctic and Antarctic. Now that gap in research has been plugged, according to scientists who carried out a detailed analysis of temperature variations at both poles. Their study indicates that humans have indeed contributed to warming in both regions. Researchers expected this result for the Arctic - because of the recent sharp increase in the melting of sea ice in the summer in the region - but temperature variations in the Antarctic have until now been harder to interpret. Today's study, according to the researchers, suggests for the first time that there's a discernable human influence on both the Arctic and Antarctica. Read the full story here. Miss M.

Power Cut Threats...
The UK will experience prolonged power cuts in about five years unless urgent action is taken now, a report warns. It said a third of generation capacity was due to be decommissioned by 2020, but was not being replaced fast enough. The report, by nuclear supporting Fells Associates, said new reactors would not be ready in time, and questioned spending on renewable energy. Read the full report here. Miss M.

Coastlines going back to the sea...
Some parts of the British coastline are so badly eroded they are not worth protecting from the sea, the new head of the Environment Agency has said. Lord Smith of Finsbury said work was already under way to identify areas of the east and south coast most at risk. He told the Independent that the UK faced hard choices over which coasts to defend and which to leave to the sea. Lord Smith said parts of north-east Norfolk and Suffolk were in the most immediate danger of collapse.
'Huge issue' The former culture secretary said it would not be possible to save all coastal homes from sea erosion, but that the agency would do its "level best" to protect places where there were significant numbers of properties.

Norfolk erosion - Year 10s!
A massive thank you to Miss Doan for spotting this - Year 10s who are going to Norfolk in September this article is extremely relevant to your coursework next year. Have a look!! Miss M.

Artic losing ice...
The Arctic is losing its old, thick ice faster than in previous years, according to satellite data.
The loss has continued since the end of the Arctic summer, despite cold weather across the northern hemisphere.
The warm 2007 summer saw the smallest area of ice ever recorded in the region, and scientists say 2008 could follow a similar pattern.
Older floes are thicker and less saline than newly-formed ice, meaning they can survive warm spells better.
Ice more than two years old now makes up about 30% of all the ice in the Arctic, down from 60% two decades ago.
The shrinking of Arctic ice has global implications, as its white surface reflects solar energy back into space whereas the open ocean absorbs it. Read the full story here. Miss M.

Ever wondered how they build stuff in the sea?!
How cool a boat on legs! Have a look at this story to see how they build off-shore wind farms. Miss M.
