Texas A&M study proves pollution from China And India affecting world...( er months. Because of various clim...),Health

Because of various climate conditions, the northern Pacific Ocean is more susceptible to the aerosol effect in winter. Aerosols can affect the droplets in clouds and can actually change the dynamics of the clouds themselves, Zhang adds.

The Pacific storm track carries these polluted particles to the west coasts of Canada and the United States, across America and eventually, most of the world, Zhang notes.

"The Pacific storm track can impact weather all over the globe," he says.

"The general air flow is from west to east, but there is also some serious concern that the polar regions could be affected by this pollution. That could have potentially catastrophic results."

Soot, in the form of black carbon, can collect on ice packs and attract more heat from the sun, meaning a potential acceleration of melting of the polar ice caps, he believes.

"It possibly means the polar ice caps could melt quicker than we had believed, which of course, results in rising sea level rates," he adds.

The pollution from the storm tracks could also signify wild weather changes, he believes.

"You might have more storms, and these storms might be more severe than usual," he says.

"Or it could lead to the opposite severe droughts in other areas. The Pacific storm track plays a crucial role in our weather, and there is no doubt at all that human activity is changing the world's weather."
