This week marks record temperatures around the world, scientists say

Record-high temperatures have been placed around the world this week in an unusual heat wave that has lasted a long time, intensifying concerns about climate change, reports The Guardian, the Periscope broadcast.

Last month in California, we had power cuts due to alarming air conditioning requirements. Algeria has experienced the highest temperatures recorded in Africa. Britain, meanwhile, has experienced its third wave of heat ever, melting even the peaks of a science building in Glasgow.

The World Meteorology Organization has said that these rising temperatures match the global climate cyclical phenomenon known as La Nina.

Globally, the hottest year was 2016. Last year, without La Nina, temperatures reached the highest rate. This year, the same trend is continuing.

It's not just magnitudes in any given location but high temperatures affecting such large areas. /Periscopi
