Rising temperatures and killer heatwaves around the world

A deadly heatwave has claimed at least 1,150 lives in Pakistan, even though a sea breeze brought some much-needed respite, lowering temperatures in the port city of Karachi.

The extreme heat went as high as 44 deg C - the highest temperature recorded in the country since 1981. Power outages also left many without fans, water or light at the beginning of Ramadan, when many Muslims do not eat or drink during daylight hours.

But Pakistan is not the only country to experience scorching weather.

Earlier in May, a heatwave in India also took thousands of lives. Maximum temperature in the southern states Andhra Pradesh and Telangana, which account for a third of India's poultry output, rose above 47 deg C in the last week of May.

Hospitals in India battled to treat victims as the death toll rose above 2,000 - the highest number recorded in two decades.

Spain and Portugal are also currently feeling the heat, with temperatures soaring above 40 deg C on Monday, June 29.

The fiery temperatures prompted Spain's national weather office to put the region of Cordoba on red alert, the highest level on the scale, meaning the weather posed an "extreme risk" to health.

China's meteorological authority issued a yellow warning for high temperature in the country's southern regions on Sunday, June 28. A heatwave is expected to sweep across most of the south of China with rising temperatures reaching 39 deg C in some areas.
