Climate milestone demands shift to renewable energy

The world was quietly but powerfully reminded of the urgent need to shift to sustainable, clean energy sources when atmospheric levels of carbon dioxide (CO2) broached 400 parts per million for the first time in human history. Announced in May by scientists at Hawaii’s Mauna Loa Observatory, this represents a critical point on the pathway to dangerous levels of global warming, where extreme weather conditions, record high temperatures, floods and drought will become increasingly common – with associated human misery and economic loss. WWF’s Global Climate & Energy Initiative says the imperative to drive down CO2 emissions causing climate change has never been stronger, requiring a fast shift to renewable energy, supported by energy efficiency, to drastically reduce CO2 emissions.
