Severe weather around the world

BlogpostbyTristan Tremschnig

The world has recently experienced a series of calamitous weather events. News headlines have painted a grim picture: flooding, drought, landslides and record ice melt in the arctic. These events stretch to every corner of the globe, but their effects are all too heavily felt by the poorest people in the world.

We need to ask ourselves: is this the world we want?

While it is true that it is difficult to attribute any single weather event to climate change, it is agreed that climate change is likely to bring more extreme weather events with it. Indeed, many of these recent events are consistent with what can be expected as global temperatures continue to rise. In very broad terms, this is because climate change is putting more energy (heat) into the world’s weather systems. It is probable that this will cause dry areas to get drier and wet areas to get wetter.

• Arctic: June 18 – Satellite images of the Artic have shown the extent of floating ice that melts and refreezes was 824,000 square kilometres less than the same period in 2007 the year of record low extent since records started in 1979. This followslast yearssecond greatest sea ice melt on record.
• Uganda: June 25 – A landslide devastated two villages, killing about 30 people and leaving more than 100 missing. A local officialsaidit rained heavily in the area for two days and that the landslides in the area may be more severe than the ones that occurred there in 2010.
• North and South Korea: 26 June The most severe drought since record keeping began 105 years ago is gripping the Korean Peninsula.According to reports, 80% of South Korea is experiencing severe drought, with Seoul experiencing only seven percent of the rainfall it experienced during the same period last year.
• Bangladesh: June 28 – The death toll from floods and landslides have been climbing. Unusually heavy monsoon rains have disrupted road, rail and air links, local officials said.
• Nigeria: June 28 Heavy rains and flooding have affected residents in the capital, Lagos. In some areasproperties were swept away and major roads were blocked.
• United Kingdom: June 28 Torrential rain has caused flash floods in parts of the UK, while Northern England, the Midlands, Scotland and NorthernIrelandwere hit by storms that brought lightning,giant hailstones, squalls and tornadoes. At the same time, southern parts of Britain experienced dryweatherand temperatures of up to 28C.
• USA: June 28 – A wildfire has forced the evacuation of 35,000 people from Colorado’s second-largest city. One person has been killed and 346 homes incinerated, making itthe most destructive blazein the states history. Waldo Canyon was the site of one ofover 40 large, uncontained wildfires being fought across the United States, the bulk of them in ten western states: Colorado, Montana, Wyoming, Utah, Idaho, South Dakota, Arizona, New Mexico, Nevada and even Hawaii.
• India: June 29 900,000 peoplehave been displaced and 27 people have died due to floods in the north-eastern state of Assam. Torrential rain has hit the region, inundating 21 of the 27 districts in the state, as the seasonal monsoon rolls across the subcontinent.
• USA: June 29 – Stifling heat and dry conditions are persisting across the centre the Midwest. The drought conditions are hitting at the worst possible time for young corn and soybean plants already suffering from a lack of rain,according to agricultural meteorologists. At least 15 climate scientiststold the Associated Pressthat the long hot summer is what could be expected in global warming. 2.1 million acres have burned in wildfires, and more than two-thirds of the country is under drought conditions, according to areport inTime.
• Greenland: 29 June – The Greenland ice sheet is set for another record melt this year.Climate Central reportsthat it is approaching a “tipping point” into a new and more dangerous melt regime in which the summer melt area covers the entire land mass.
• USA: 30 June – The Washington D.C. region, Maryland, and Northern Virginia were lashed by asudden and violent stormthat killed at least 13 people. Even theWashington Post writes (June 30, 2012): “As the intensity of the heat wave, without reservation, was a key factor in the destructiveness of this derecho event–it raises the question about the possible role of manmade climate warming (from elevated greenhouse concentrations).”
