Deforestation in the Amazon increased by nearly a third over the past year, according to Brazilian government figures released on Thursday.

The data confirms a feared reversal in what had been steady progress over the past decade against destruction of the world's largest rainforest.

Satellite data for the 12 months through the end of July 2013 showed that deforestation in the region climbed by 28% compared with a year earlier. ... Read more about Deforestation in Amazon jungle increases by nearly a third in one year

A new analysis of temperature records indicates that the Western Antarctic Ice Sheet is warming nearly twice as fast as previously thought.

US researchers say they found the first evidence of warming during the southern hemisphere's summer months.

They are worried that the increased melting of ice as a result of warmer temperatures could contribute to sea-level rise.

The study has been published in the journal Nature Geoscience. ... Read more about West Antarctic Ice Sheet warming twice earlier estimate

Scientists in the Arctic are warning that this summer's record-breaking melt is part of an accelerating trend with profound implications.

Norwegian researchers report that the sea ice is becoming significantly thinner and more vulnerable.

Last month, the annual thaw of the region's floating ice reached the lowest level since satellite monitoring began, more than 30 years ago.

It is thought the scale of the decline may even affect Europe's weather. ... Read more about Arctic ice melting at 'amazing' speed, scientists find

The largest power potential from wind in the spring, summer, and fall typically occurs in the evening and early morning when the regional load demand is not at its peak. Although the wind resource peak power potential does not coincide with the peak of the regional load demand, wind can still be used to meet some of the Region’s energy needs. Figure 4.1 illustrates the seasonal hourly wind potential.

July 23 (AlertNet) - Disputes over water are common around the world, exacerbated by climate change, growing populations, rapid urbanisation, increased irrigation and a rising demand for alternative energy sources such as hydroelectricity.

Following are a few of the regions where competition for water from major rivers systems is fuelling tension.
