Over the next few decades, global warming-related rises in winter temperatures could significantly extend the range of the southern pine beetle—one of the world’s most aggressive tree-killing insects—through much of the northern United States and southern Canada, says a new study. The beetle’s range is sharply limited by annual extreme temperature lows, but these lows are rising much faster than average temperatures—a trend that will probably drive the beetles’ spread, say the authors. The study was published today in the journal Nature Climate Change.... Read more about Climate May Quickly Drive Forest-Eating Beetles North, Says Study
São Paulo, in southeast Brazil, is the largest city in South America and the 7th largest metropolitan region in the world, with more than 21 million people. It's the engine behind Brazil's richest state, which is responsible for one-third of the country's GDP.
And right now, the region is running dangerously low on water, thanks to the worst drought in eight decades.
Big Data is transforming agriculture, and just in time. The demand for food is expected to double by 2050 as the world's population heads toward 9 billion people and increasing incomes allow many more to afford a better diet. Lack of water is a critical constraint to increasing food production, particularly as droughts and other consequences of climate change are making water scarcer. ...

Water, or the lack thereof, is one of the defining challenges of the 21st century. As temperatures rise and droughts become more frequent, the threat of dwindling water resources worries not just environmentalists and governments but companies and their investors, too. ...

NEW YORK - One year ago, I was in Brazil to launch the Brazilian chapter of the United Nations Sustainable Development Solutions Network (SDSN), an initiative of UN Secretary-General Ban Ki-moon. The main message I heard that day was that São Paulo was suffering from a mega-drought, but that state and local politicians were keeping it quiet. This is a reality around the world: too many political leaders are ignoring a growing environmental crisis, imperiling their own countries and others. ...
