With Climate Change Comes Extreme Weather
The question to consider is how global warming and climate change are affecting the weather around the world.
Droughts, wildfires, sea levels rising, storms and floods, ice caps melting, heat waves, cold snaps: Many people are asking whether these are being caused by climate change. This is the wrong question to ask, because obviously there have always been droughts, wildfires, heat waves, storms and floods. The question we need to consider is how global warming and climate change are affecting the weather around the world.
Not that this is an easy question to answer, but at least it’s an
appropriate one. It’s appropriate because if climate change is indeed contributing to these events, we need to understand the extent of such impact, and then work out what resources and efforts we need to put into mitigating it. And then a more difficult question arises about how the responsibility of addressing this global problem can be fairly and equitably managed amongst the many nations and economies of the world.
Let’s answer the easy one first and leave the more difficult question for another time.
KNOWING THE DIFFERENCE
Before I go any further, let me quickly remind us of the differences between global warming, climate change and the weather. As the saying goes, climate is what you expect, weather is what you get. In other words, climate is a long-term trend of events, while weather is what happens on a daily basis. For example, the weather can change in a few minutes, but the climate changes over much longer time frames. But they are linked, and we measure and record weather events which then give us an overall view of the long-term trends such as hotter days, more severe droughts, etc.
As for global warming, it is the increase in average global temperatures above what we would expect without the greenhouse effect, which is a result of increased levels of greenhouse gases — mainly as a consequence of human activity.
As I have done in all of my previous articles and will continue to do, I’ll start with the facts we have available. Yes folks, facts — this currently illusive concept — and not opinion, and certainly not belief. To develop appropriate measures and policies, to act on them and to do this properly, we will need a rational and scientific approach, and not be driven by ideology. We have no other choice than to have to rely on the science we have, as imperfect as it may appear.
So, let me summarize a few of the facts about extreme weather we have in front of us. According to the BBC, just this year, the UK has seen the warmest February day on record at 20.6°C (69.08°F) — the first time the country witnessed a temperature of over... LINK
