Dramatic climate changes and weather extremes already affecting millions of lives, but solutions exist.  World Bank  WASHINGTON, November 23, 2014 – ‘ the planet warms further, heat-waves and other weather extremes that today occur once in hundreds of years, if ever, would become the “new climate normal,” creating a world of increased risks and instability.  The consequences for development would be severe as crop yields decline, water resources shift, sea-levels rise, and the livelihoods of millions of people are put at risk, according to a new scientific report released today by the World Bank Group. Climate change impacts such as extreme heat events may now be unavoidable because the Earth’s atmospheric system is locked into warming close to 1.5°C above pre-industrial levels by mid-century, the report said. Even very ambitious mitigation action taken today will not change this, it said.’
