It seems summer has arrived. Too bad it took until almost the middle of August to get here. Not that we鈥檙e the only place enduring weird weather.

When we were lamenting the cool temperatures and cloudy skies of July, the rest of the continent was sweltering in record heat and withering humidity. Those kinds of conditions have become so commonplace, some cities, like Toronto, have instituted a system of extreme heat alerts that include a protocol to extend the operating hours of public pools, handing out water in parks and visits by public health officials to rooming houses, boarding homes and other residential premises to ensure residents aren鈥檛 suffering. So far this summer Toronto鈥檚 medical officer has issued six such alerts.

Meanwhile much of Europe has been soggy and cooler than normal this summer after a hot, dry spring.

In Africa, Somalia is suffering its worst drought in 60 years; the entire Horn of Africa, which also comprises Ethiopia and Kenya, has received two to eight inches less rainfall this year than normal. That鈥檚 sparked a famine that has claimed the lives of more than 29,000 children under the age of five over the past three months.

Climatologists like to remind us that such extremes aren鈥檛 as wild and unusual as they seem. The La Nina and El Nino 91原创ena, in which the surface temperature of the eastern tropical Pacific Ocean is warmer or cooler than normal, have been influencing the climate for more than 20,000 years.

Scientists say that it鈥檚 impossible to blame specific weather events like storms, droughts, heat waves and extreme cold on global warming caused by humans. 

But climate change, settlement of expanding populations into areas prone to extreme weather and our inaction to deal with that likelihood have a way of turning bad weather into a disaster.

So as much as we like to curse Mother Nature when the weather鈥檚 foul, we must also shoulder some of the blame.
