A truffle is seen on a table in Alba, north-western Italy November 11, 2013. Located in the heart of the Langhe – the hilly southern area of Italy's northwestern Piedmont region – Alba is the country's capital of white truffles, a variety of the prized fungus which grows underground. Truffles are found two to eight inches (5-20cm) below the ground near the roots of trees. They give off an odour which lasts for a limited period of time and can be detected with the assistance of well-trained dogs and experienced hunters. Output of white truffles, which are not cultivated and only grow naturally in forests, has fallen in Italy over the past few years, largely because climate change has brought a damaging mix of drought and torrential rains.

A firefighter carries a woman from her car after it was caught in street flooding as a powerful storm moves across Southern California on February 17, 2017 in Sun Valley, California. After years of severe drought, heavy winter rains have come to the state, and with them, the issuance of flash flood watches in Santa Barbara, Ventura and Los Angeles counties, and the evacuation of hundreds of residents from Duarte, California for fear of flash flooding from areas denuded by a wildfire last year.

Workers carry a rope line to fasten a decommissioned ship at the Alang shipyard in the western Indian state of Gujarat, March 27, 2015. The European Union plans to impose strict new rules on how companies scrap old tankers and cruise liners, run aground and dismantled on beaches in South Asia. However the practice in India, Bangladesh and Pakistan, hazardous for humans and the environment, will still be hard to stop. European, Turkish and Chinese recyclers are set to benefit from the revamped standards. Depending on raw material prices, ship owners can make up to $500 per tonne of steel from an Indian yard, compared with $300 in China and just $150 in Europe. (Photo by Amit Dave/Reuters)
