Prediciton on Aerosols and Climate Change

Predict what effect aerosols may have on climate change:

There is no doubt that the climate is changing, but one thing that is becoming hard to prove is why it's changing. How do we know the Earth's climate is warming? This is proved by many, many reasons. According to the National Climate Data Center, there are many, many surface temperatures taken daily and analyzed to show that the warming trend is apparent. It is also shown by the "melting of moutain glaciers on every continent, reductions in the extent of snow cover, earlier blooming of plants in the spring, a shorter ice season on lakes and rivers, ocean heat content, reduced artic sea ice, and rising sea levels."

Now that we've proved that it is happening, we just need to figure out why. While there are both natural and human causes, it is said that humans are the primary cause of the warming. Aerosols can come from sources such as transportation, industry, agriculture, and urban land use. According to Science Daily "Recent studies suggest that increased aerosol loading may have changed the energy balance in the atmosphere and at the Earth's surface, and altered the global water cycle in ways that make the climate system more prone to precipitation extremes."

So, one of the biggest changes we can see happening are changes in precipitation patterns. This change may not only change regional water sources, but there is also a possibility it may change the regional and global circulation system- which has a huge effect on the Earth's climate.
