Cleantech depends on energy policy. US President Obama deals with two core climate issues: meeting the larger goal of reducing carbon emissions, and finding a way of rescuing the renewables industry from Wall Street’s collapse. The benchmark of 450 ppm is a crucial figure issued by the Intergovernmental Panel on Climate Change. ‘Limiting concentration to [...]

Farmland and climate change are related in the way that ‘global warming will make it harder to feed the world in 2050.’ Higher temperatures are feared to possibly ‘turn arid shrub lands into deserts while improving the growing season in colder steppes.’
There are other possibilities as to the effect of global warming: evaporation could occur [...]

The billion-dollar floodgates being installed in Venice might not save the city. These mobile floodgates are being constructed with the aim of safeguarding the 1,300-year-old island city of Venice. The ambitious and costly engineering feat may not be enough to protect the city from rising sea levels due to climate change.
Having risen from mudflats in [...]

UN Secretary General Ban Ki-moon warned that ‘the Arctic is warming faster than anywhere else on Earth’ and ‘could be ice-free by 2030.’ Ban recently visited the Polar Ice Rim in the Norwegian archipelago of Svalbard where he observed firsthand the impact of climate change on the Arctic.
Ban promptly called on governments to achieve in [...]

Pakistan has started to be beset by water problems, undermining its stability even more. Water shortages in the country have led to grain shortfalls. Flour became scarce in 2008. Thousands of government troops were sent to guard wheat stores. The rivers are drying up as the glaciers that regulate Kashmir’s waters melt. It is estimated [...]

Oceans becoming more acidic and warmer due to emissions of carbon dioxide would cause the death of coral reefs around the world by the end of the century, according to a warning from several experts that recently gathered in London.
More than twenty experts on coral reefs and climate change came together on behalf of several [...]

The world is increasingly close to the atmospheric limit for carbon dioxide. Failure to drastically and urgently reduce CO2 emissions will very soon make it impossible to avoid an average warming of the Earth at the 2ºC threshold which is considered dangerous to life. Moreover, we have already spent half of a hypothetical budget of [...]

The international community set a final date to agree on a plan to reduce greenhouse gases responsible for global warming, but there was no assurance that an agreement will be forged. In the hope of averting a potential failure of the planet, nearly 2,000 scientists, including the most eminent climate scientists worldwide, met from March [...]

According to Climate Change scientific experts, the sea levels will rise much higher than the earlier estimates by UN’s Intergovernmental Panel on Climate Change (IPCC). Well, this is not good news to people living in low lying areas, which is nearly 10 percent of the world’s populations.
The latest studies of Polar ice sheets at Greenland [...]

The animals that depend on the polar sea ice are threatened by global warming. This is one of the more immediate adverse impacts of climate change. This is also one of the more important points of reference contained in the latest report of the Intergovernmental Panel on Climate Change (IPCC). Like many other polar species, [...]
