For many years I have been using the expression “Global Warming is the ultimate weapon of mass destruction” Why?

By way of an answer let me say that, without a doubt, it is likely to kill more people than human conflict ever has and is one of the most serious things facing our planet at the moment. It is likely to trigger major catastrophic events, such as flooding, storms, famine and Drought. We only borrow the planet and it is our duty to hand it onto our children and grandchildren in better shape, NOT much worse.

We CAN influence Global Warming if you “Turn Down, Switch Off, Recycle, Walk”

So what is behind Global Warming? The answer in a nutshell is ‘The enhanced Greenhouse effect’. Without it we would freeze to death as the mean Temperature of the Earth would be around -180C. Instead the temperature is around 150C, ideal for life. Carbon Dioxide, Water vapour, Methane, Nitrous Oxide and other minor gases in the Atmosphere act like panes of glass in a greenhouse, or a blanket, keeping in some of the heat we receive from the sun, instead of it escaping back into space. That was fine but now there are far more layers of the ‘blanket’ than there should be (more gases in the atmosphere) and the Earth is getting too warm.

Carbon Dioxide amounts in the atmosphere were more or less constant until the Industrial Revolution but have risen at an ever increasing rate since and as a result the temperature of the Earth has risen in tune by about 0.60C, most of that since 1970. In the EU every person produces 11 tonnes of Carbon Dioxide a year! Amounts in the atmosphere have increased by 35% and are now higher than at any time in the last 650,000 years. Methane, largely from tips, cattle and paddy fields has doubled and is far more effective as a ‘blanket’ than Carbon Dioxide, although there is less of it. Nitrous Oxide, from fertilizers and cars, is over 300 times as effective!

Believe it or not the Greenhouse Effect was first recognised in 1896 and the scientific community have been publicising it for years. Unfortunately, until recently, much of this fell on deaf ears (and in George Bush’s case still do!!) and in many ways it is too late to do anything to stop it, although if we act quickly we should be able to stabilise the effects in about 100 years time.

We can all see the effects. The seasons have shifted (here in the UK the growing Season has increased by 10 days). Diseases have become more widespread. Trees have died. Animals have lost their habitat. Glaciers have melted. The Arctic ice has shrunk. The sea has risen some 15cm, already flooding places like Tuvalu. Floods and storms have become more frequent, such as Katrina which produced more energy than the US grid does in several weeks, as it devastated the Southern States.
