Providing clean, renewable energy to the 1.4 billion people who are living without electricity is the No. 1 priority of the United Nations, the secretary general of the U.N. said during a visit Aug. 24 to the U.S. Department of Energy's National Renewable Energy Laboratory.

For two decades, the world’s governments have failed to meet their own commitment to reduce emissions of carbon dioxide, the main heat-trapping gas. As frustration builds among scientists, some of them have begun to argue for research on a potential last-ditch option in case global warming starts to get out of control. It is called geoengineering — or directly manipulating the Earth’s climate.

The idea sounds like science fiction, but it is not.

Changes in the global climate that cut food production triggered one-fifth of civil conflicts between 1950 and 2004

Cyclical climatic changes double the risk of civil wars, with analysis showing that 50 of 250 conflicts between 1950 and 2004 were triggered by the El Niño cycle, according to scientists.

Some numbers are fundamental and iconic: think pi in mathematics and the speed of light in physics. They provide a cornerstone upon which a vast edifice of science can be built, leading ultimately to much of our prosperity and wellbeing.

Water systems at risk from growing demand for food - expert
Show

LONDON (AlertNet) – Efforts to feed an extra 2 billion people by mid-century could lead to widespread destruction of forests, wetlands and other natural systems that protect and regulate the world’s water, researchers warn.

But finding ways to boost agricultural production while protecting nature could produce big benefits, including reduced poverty and hunger in some of the world’s most fragile countries and hikes in food production that are sustainable beyond 2050.

Scientists have produced what they say is the first complete map of how the ice moves across Antarctica.

Built from images acquired by radar satellites, the visualisation details all the great glaciers and the smaller ice streams that feed them.

The map has been published online by Science magazine.

The United Nations Economic and Social Council (ECOSOC) voted to establish a committee on global geospatial information management in order to enhance international dialogue and cooperation on spatial data infrastructures. The UN recognizes the benefits of geospatial information for application to humanitarian, peace and security, environmental and development challenges as well as to responses to climate change, natural disasters, pandemics, famines, population displacement, and food and economic crises.
