When it comes to the weather and climate, most of us think only about what is happening in the atmosphere. If we ignore the ocean, however, we miss a big piece of the picture.
Air conditioning provides welcome relief from hot weather and is an obvious solution to prevent heat-related illnesses and deaths. But AC systems themselves can lead to health problems if not maintained properly.
“Forest fires can often start in the most innocuous of circumstances, sometimes from a casually discarded item which sets one tree alight and subsequently spreads to cover an enormous area. They are also triggered by weather conditions such as unseasonable heat and high winds, a combination of which can lead to entire forests being engulfed within hours. Not only do these disasters cause devastation to land and forestry; they can also claim hundreds of innocent lives, not least those of courageous firefighters who give their lives trying to save others.”

You’ve probably heard that weather is getting more extreme and that this is in part because accumulating greenhouse gases have caused the air at earth’s surface to warm by an average of 0.8 degrees celsius over the last century. But how could a barely perceptible rise in air temperature lead to such crazy changes in weather?
Well, that air temperature rise actually only amounts to 1% of the extra energy absorbed by earth’s atmosphere over the last century – a few percent has been absorbed by land and almost all the rest has been soaked up by the oceans. That increase in ocean heat content is the energy equivalent of an atomic bomb exploding every second for the last 100 years. And THAT matters because heat stored in the oceans has a big impact on the weather.
