Climate change 'to halt ice age'
A new model of the Earth's climate suggests that human-made carbon dioxide emissions may prevent the onset of the next ice age.
Based on geological history, the Earth would be expected to enter a new ice age in 10,000 to 100,000 years.

Clouds can predict climate changes
The properties of clouds can be a key to predicting coming climate changes. This is shown by research at the University of Gothenburg in Sweden - which has also studied urban pollution.
The earth's climate field is regulated by the balance between incoming solar radiation and outbound heat radiation. The aerosol content of the atmosphere, that is, the proportion of particles in the air, functions as a regulator: cooling off by reflecting incoming light, warming up by absorbing the outbound heat radiation.

In a few year's time, the ecology of the UK could look very different from today.
While many new species will be harmless and add to our rich mix of biodiversity, a few could become problematic, scientists warn.
Ecologists are already keeping an eye on those non-native species that have already established in the UK but have the potential to spread.

The past decade in the northern hemisphere was the hottest in 1,300 years, scientists said.
The research was based on the makeup of corals, sediment and ice. Information on tree rings was not included in the research; otherwise the past decade would have been called the hottest in past 1,700 years.

Sea levels in parts of Scotland will have risen by about 30cm by the 2080s, a Dundee University report suggests.
Researchers were analysing the risk of coastal flooding and ways to manage it.
More than 300 coastal floods since 1849 were studied, with the Solway Firth, Moray Firth, Aberdeenshire and Firth of Clyde having suffered the most.

A group of northern California scientists have found a new bend in the Gordian knot of global warming: coastal cooling.
The team, headed by meteorologist Robert Bornstein of San Jose State University, has found that as temperatures rise in California, so do pressure differences that control cool Pacific winds. That means higher temperatures inland create lower ones at the coast.

ESA trains next generation of atmospheric scientists
In a world in which human activity is beginning to alter atmospheric composition with substantial implications for climate and air quality, it is more pressing than ever that the scientists of tomorrow understand atmospheric processes and how the processes may change in order to anticipate the effects and minimise potential dangers.

Carbon: The Deep Geological Cycle and its Effect on the Air we Breathe
This one-day meeting of the Geological Society at the Burlington House, London, brings together a number of world experts to highlight the role of the geological sciences in understanding Earths deep carbon cycle, in a series of review talks that will demonstrate how studies of the Earths interior are essential for a full understanding of climate change.

The Earth will warm about 2.4 C above pre-industrial levels even under extremely conservative greenhouse-gas emission scenarios and under the assumption that efforts to clean up particulate pollution continue to be successful, according to a new analysis by a pair of researchers at Scripps Institution of Oceanography at UC San Diego.
