Climate Change Update: Reports Show Growing Risks

As the UN climate change talks continue in Doha, Qatar, several reports over the past month have highlighted a sombre picture of the Earth's changing climate, raising alarm bells in particular for the world's poorest regions. A report from the World Bank launched last month (18 November) warns that the planet "is on track for a four degrees Celsius warmer world" by 2100, marked by extreme heat waves, declining food stocks, loss of biodiversity and life-threatening sea level rise. This is double the generally accepted two degrees Celsius threshold beyond which catastrophic climate change impacts are expected.

Climate change mitigation ‘far cheaper than inaction’

Tackling the global climate crisis could reap significant economic benefits for both developed and developing countries, according to a new report. The impacts of climate change and a carbon-intensive economy cost the world around US$1.2 trillion a year — 1.6 per cent of the total global GDP (gross domestic product), states 'Climate Vulnerability Monitor: A Guide to the Cold Calculus of A Hot Planet'.

Geospatial initiative shows the way

GeoSUR, a Latin American and Caribbean (LAC) open access and web-based initiative for geospatial data-sharing, has received a boost at the Eye on Earth Summit in Abu Dhabi (12-15 December). The conference "Networks of Networks" working group accepted GeoSUR – one of the first such regional networks in the developing world – as a "case model".

Ten-point plan to save the oceans

The world has made lacklustre progress in meeting most of the commitments it made 20 years ago to safeguard the oceans, says a report. At the 1992 Earth Summit in Rio de Janeiro, Brazil, agreements were made on issues such as sustainable fisheries and aquaculture, capacity building, and biodiversity; later, the Johannesburg Summit in 2002 in South Africa set targets and timetables to achieve those goals.

Banana peel can purify water, say scientists

[MONTEVIDEO] Banana peels can be used to purify drinking water contaminated with toxic heavy metals such as copper and lead, according to a study. Researchers from the Bioscience Institute at Botucatu, Brazil, said that the skins can outperform even conventional purifiers such as aluminium oxide, cellulose and silica. These have potentially toxic side effects and are expensive.
