Arctic sea ice melt 'even faster'
(Jun 19, 2008)
Arctic sea ice is melting even faster than last year, despite
a cold winter. Data from the US National Snow and Ice Data Center
(NSIDC) shows that the year began with ice covering a larger area
than at the beginning of 2007. But now it is down to levels seen
last June, at the beginning of a summer that broke records for
sea ice loss.

Vast cracks appear in Arctic ice
(May 24, 2008)
Dramatic evidence of the break-up of the Arctic ice-cap has emerged
from research during an expedition by the Canadian military. Scientists
travelling with the troops found major new fractures during an
assessment of the state of giant ice shelves in Canada's far north.
The team found a network of cracks that stretched for more than
10 miles (16km) on Ward Hunt, the area's largest shelf.

Sharks swim closer to extinction
(May 23, 2008)
More than half of the world's ocean-going sharks are at risk of
extinction, a new analysis concludes. Specialists with IUCN (formerly
the World Conservation Union) found that 11 species are on the
high-risk list, with five more showing signs of decline. Sharks
are particularly affected by over-fishing as they reproduce slowly.

Global biodiversity slumps 27% in 35
years
(May 13, 2008)
The latest data on the global biodiversity of vertebrates shows
that it has fallen by almost one-third in the last 35 years. But
experts say it may still underestimate the effect humans have
had on global species counts. The Living Planet Index (LPI) follows
trends in nearly 4,000 populations of 1,477 vertebrate species
and is said to reflect the impact humans have on the planet.

World carbon dioxide levels highest
for 650,000 years, says US report
(May 13, 2008)
The concentration of carbon dioxide in the atmosphere has reached
a record high, according to the latest figures, renewing fears
that climate change could begin to slide out of control. Scientists
at the Mauna Loa observatory in Hawaii say that CO2 levels in
the atmosphere now stand at 387 parts per million (ppm), up almost
40% since the industrial revolution and the highest for at least
the last 650,000 years.

Rainforest seeds revive lost paradise
(May 5, 2008)
Six years ago the area around Samboja in Borneo was like much
of the world's tropical rainforest: denuded. The trees had been
cut for timber, the land burnt, and in place of what should be
some of the richest biodiversity on the planet were thousands
of acres of grass. But from this ruined landscape a fresh forest
has been grown, teeming with insects, birds and animals, and cooled
by the return of moist clouds and rain.
