While climate change deniers still try to dishonestly pick holes in the science, and spread long disproved lies, the visible effects of climate change are becoming more and more obvious:
Warning: extreme weather ahead
Tornados, wildfires, droughts and floods were once seen as freak conditions. But the environmental disasters now striking the world are shocking signs of ‘global weirding’
Drought zones have been declared across much of England and Wales, yet Scotland has just registered its wettest-ever May. The warmest British spring in 100 years followed one of the coldest UK winters in 300 years. June in London has been colder than March. February was warm enough to strip on Snowdon, but last Saturday it snowed there.
Welcome to the climate rollercoaster, or what is being coined the “new normal” of weather. … 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.
Last year, more than 2m sq km of eastern Europe and Russia scorched. An extra 50,000 people died as temperatures stayed more than 6C above normal for many weeks, crops were devastated and hunderds of giant wild fires broke out. The price of wheat and other foods rose as two thirds of the continent experienced its hottest summer in around 500 years.
This year, it’s western Europe’s turn for a mega-heatwave, with 16 countries, including France, Switzerland and Germany (and Britain on the periphery), experiencing extreme dryness. The blame is being out on El Niño and La Niña, naturally occurring but poorly understood events that follow heating and cooling of the Pacific ocean near the equator, bringing floods and droughts.
Vast areas of Europe have received less than half the rainfall they would normally get in March, April and May, temperatures have been off the scale for the time of year, nuclear power stations have been in danger of having to be shut down because they need so much river water to cool them, and boats along many of Europe’s main rivers have been grounded because of low flows. In the past week, the great European spring drought has broken in many places as massive storms and flash floods have left the streets of Germany and France running like rivers.
But for real extremes in 2011, look to Australia, China and the southern US these past few months. In Queeensland, Australia, an area the size of Germany and France was flooded in December and January in what was called the country’s “worst natural disaster”. It cost the economy up to A$30bn (£19.5bn), devastated livelihoods and is still being cleaned up.
In China, a “once-in-a-100-years” drought in southern and central regions has this year dried up hundreds of reservoirs, rivers and water courses, evaporating drinking supplies and stirring up political tensions. The government responded with a massive rain-making operation, firing thousands of rockets to “seed” clouds with silver iodide and other chemicals. It may have worked: for whatever reason, the heavens opened last week, a record 30cm of rain fell in some places in 24 hours, floods and mudslides killed 94 people, and tens of thousands of people have lost their homes.
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. [My bolds]
Argue with the science if you must, but it’s pretty hard to argue with the world. The effects of climate change are upon us. If runaway feedback loops kick in (and there’s no reason to believe that they won’t) then it doesn’t end well.
The attitude of governments world wide seems to be that it’s far too expensive and inconvenient to do anything about climate change, so let’s just carry on as usual. (Key wants to dig up all the lignite.) Even in narrow economic terms business as usual is stupid short term thinking. But in broader practical and moral terms it’s nothing short of madness.
