High temperatures spark fears of climate change

In recent years, climate change has become an increasing phenomenon with scholars arguing that temperatures had gone up by as much as two degrees on average and this spelt doom for developing countries in particular.

 

Some of the signs of climate change, scholars say, are increased famines and flooding in some areas.

 

Glaciers in the Atlantic regions are also expected to thaw, increasing flooding risks and endangering polar wildlife.

 

Several meetings have been held to come up with a global response to the threat posed by climate change, but so far a consensus has been elusive.

 

Zimbabwe has been at the throes of continuous droughts and others claim that this is a sure sign that climate change has set in.

 

Recent flooding in the Okavango Delta in Botswana seems to have affirmed the climate change theory, as the delta last flooded in the 1970s, but burst its banks recently.

 

An expert, however, warned last year, that scholars should be wary of declaring climate change as the reason for the extreme weather patterns.

 

Piotr Wolski, a hydrology expert based in Bostwana said he was able to accurately predict the flooding of the Okavango, as this was part of a 30-year cycle that moved from extreme dryness to flooding over a defined period.

 

The expert defined this phenomenon known as Pacific Decadal Oscillation, as a shift between phases of warmer and cooler surface temperatures half a world away in the Pacific Ocean.

 

“There has been no cyclicity change,” Wolski noted. “A change in climate would be a modification of the cycle, and so far we have not seen that.”

 

Wolski did not deny the existence of climate change, but rather called for further inquiry into the area.

 

So in this case the extreme heat being experienced in Zimbabwe and most of southern Africa could be a result of cyclic weather patterns, but further studies into this phenomenon still need to be carried out.

 

As the meteorological department pointed out that this is the hottest October since 1962, 49 years ago, it fits perfctly into the oscillation phenomenon that has a range of between 20 to 50 years for a cyclic weather pattern.

 

However, critics of climate change are often labeled as dissidents and denialists, raising need to further study into the global warming phenomenon.
