The World Resources Institute has put together a great timeline of this year's extreme weather events:
“Over the past several months, extreme weather and climate events in the form of heat waves, droughts, fires, and flooding have seemed to become the norm rather than the exception. In the past half-year alone, millions of people have been affected across the globe – from Europe suffering from the worst cold snap in a quarter century; to extreme flooding in Australia, Brazil, China, and the Philippines; to drought in the Sahel. Records have been broken monthly in the continental United States, with the warmest spring and 12-month period experienced this year and severe fires and drought affecting large swaths of the country.”
“So how bad has it really been? Below we have put together a timeline of extreme climate and weather events in 2012. We have by no means attempted to be comprehensive in listing events, but have aimed to include some of the most significant occurrences this year. Please let us know through the comment section if we are missing some, as we plan to update the timeline periodically.”
