The Guardian... Welcome to the climate rollercoaster, or what is being coined the "new normal" of weather. What was, until quite recently, predictable, temperate, mild and equable British weather, guaranteed to be warmish and wettish, ensuring green lawns in August, now sees the seasons reversed and temperature and rainfall records broken almost every year. When Kent receives as much rain (4mm) in May as Timbuktu, Manchester has more sunshine than Marbella, and soils in southern England are drier than those in Egypt, something is happening.
Sober government scientists at the centre for hydrology and ecology are openly using words like "remarkable", "unprecedented" and "shocking" to describe the recent physical state of Britain this year, but the extremes we are experiencing in 2011 are nothing to the scale of what has been taking place elsewhere recently.
... Meanwhile, north America's most deadly and destructive tornado season ever saw 600 "twisters" in April alone, and 138 people killed in Joplin, Missouri, by a mile-wide whirlwind. Arizonans were this week fighting some of the largest wildfires they have known, and the greatest flood in recorded US history is occurring along sections of the Missouri river. This is all taking place during a deepening drought in Texas and other southern states – the eighth year of "exceptional" drought there in the past 12 years.
... Sceptics argue that there have always been droughts and floods, freak weather, heatwaves and temperature extremes, but what concerns most climate scientists and observers is that the extreme weather events are occurring more frequently, their intensity is growing and the trends all suggest long-term change as greenhouse gases steadily build in the atmosphere.
