The statement at this link points out how observed increases in air temperatures, sea levels, concentration of greenhouse gases including water vapour as well as reductions in Arctic sea ice, snow cover, permafrost and mountain glaciers are inconsistent with explanations of climate change that rely on natural influences. Deforestation, urbanisation and particulate pollution can have complex geographical, seasonal and long term effects on temperatures, precipitation and cloud properties. The statement points out this may alter atmospheric circulation and change patterns of natural variability.
Encouraged to think about what the largest threats are where I live, this is what I came up with…
Events already affecting East Anglia, UK. Eighteen months of drought in 2011-2012 affecting wildlife as well as agriculture production. Rising sea levels and coastal erosion are already problematic in this part of the world, especially pertinent as much of fenland is reclaimed marshland and sea. Increased extreme weather…well that’s more floods, storms and droughts.
The need for political leadership on climate change and deliberation about how we might achieve a healthy, sustainable world seems a million miles away from the capabilities and understanding of our current elected representatives.
