The entire world is experiencing the aftereffects of climate change. Some places are suffocating because of the heat, some places are suffocating due to waterlogging, and some places are suffering from floods and heat alternately.

While Pakistanis are taking stock of the toll of heavy rains over the past month, torrential rains continue to lash southern China, while Dallas, Texas, is reeling from 10 inches of rain in one day.

Spring temperatures in South Asia above 50°C are likely to warm the Indian Ocean. That warm water dumped more than three times the 30-year average on Pakistan in August and inundated a third of the country.

More than 1,100 people have been killed, crops destroyed, homes destroyed and calls for emergency aid are ongoing.

It will take weeks, if not months, to determine exactly how much climate change played a role in this year's flooding, but scientists agree that it is overstated. Heat waves are already intense around the world, and evaporation from land and ocean is increasing. Because the warm atmosphere can hold more moisture, cloudbursts occur and heavy rain falls.

The area around Dallas has been dry for three months, and more than half of Texas has experienced severe drought. Cotton crops were scorched in the fields. Ranchers were forced to kill their cattle due to lack of fodder. The soil hardens and cracks, forming a dry checkerboard across the landscape. This condition increases the chances of mountain floods.

About 10 inches of rain fell in 24 hours on August 21st. But the land was unable to absorb the water, causing a lot of water to flow through the city. Interstate traffic stopped. Flights are cancelled. Apartments in the historic area of ​​Old East Dallas have become swampland.

China's drought-stricken Yangtze River basin, hit by its worst hot summer in six decades, is struggling with power and water shortages. Desperate for rain, some provinces within the basin began "seeding" the clouds, sending planes into the sky to release a chemical called silver iodide to break up the clouds.

However, as the summer rains have arrived late, the authorities are worried that they will get more water than they need. More than 119,000 people have been evacuated from flood-prone areas in southwest China, according to state media.

Some parts of China are experiencing alternating drought and flooding," the Ministry of Emergency Management warned on Monday. The ministry also called on local authorities to store rainwater to help relieve other drought-stricken areas of the country.

Weather events across the Northern Hemisphere can be linked by the polar jet stream, a fast-moving air current that moves weather systems from one part of the world to another.

But scientists have found that warming trends along with recent disturbances in air circulation are simultaneously increasing the likelihood of extremes.

The jet stream disturbance is still a topic of intense research. But one recent study suggested that these factors combined have made it seven times more likely for heatwaves to be occurring simultaneously in the northern hemisphere than 40 years ago, according to the research published in January in the Journal of Climate.

"The warming trend is the main driver behind the increase in concurrent heatwaves," said climate scientist Kai Kornhuber at Columbia University in New York, who was part of a team including Singh that worked on the study.

But there is evidence, including the research around the jet stream, "to believe that atmospheric dynamics have contributed to this increasing trend".
