Scientists believe that pollution on America's west coast is coming from various sources, including vehicle emissions, industrial activities, and wildfires. The prevailing winds can also carry pollution from Asia across the Pacific Ocean to the west coast. Efforts are being made to track and reduce pollution from these sources to protect the environment and public health.

How does china pollution affect the US?

Industrial pollutants from China's increasingly robust use of coal are plating out across the globe, including here in Alaska, brought here by storms crossing the Pacific Ocean transporting tons of airborne chemicals that shower onto coastal waters and inland where it they end up in the local food chain, according to scientists studying the phenomenon. The scientists doing their sciency thing can study the pollutants to find the original source, which is why they can say as a certainty the pollution in Alaska is coming from China. As well, they are attempting to measure the percentage of overall pollution in the United States coming from China, and the numbers are a little frightening. A Scientific American article published online this week noted that a brown cloud leaving China is visible from space 'and takes about a week to cross the Pacific to the western U.S., where it accounts for as much as 15 percent of the air pollution.'


Is it true the Gulf Stream cools the climate of the east coast of the US?

No, the Gulf Stream actually warms the climate of the east coast of the US. It carries warm water from the Gulf of Mexico across the Atlantic Ocean, helping to moderate temperatures along the coastline.


Why do scientists think humans migrated from Asia to the Americans during the last ice age?

No signs of humans have been found in the Americas from before the last glaciation. The first known objects found are stone tools dated at 15,000 years old, during the last part of the glaciation. From various archaeological sites from Siberia to Alaska and down the west coast, evidence has been found linking native American DNA with that of Asian origins.


Which Canadian climate region has the wettest climate?

The wettest climate region in Canada is typically found along the west coast, in British Columbia. Areas such as the Pacific coast and Vancouver Island experience high levels of precipitation due to the influence of moist air coming in from the Pacific Ocean.


Causes of air pollution in mumbai?

The main causes of air pollution in Mumbai include vehicle emissions, industrial activities, construction dust, and open burning of waste. The city's high population density and traffic congestion exacerbate these sources of pollution, leading to poor air quality. In addition, geographical factors such as being situated on the coast can trap pollutants in the city.
