First_______Green house effect climate change
Ⅰ.INTRODUCTION
"Greenhouse gases from human activities are the most significant driver of observed climate change since the mid-20th century.1 The indicators in this chapter characterize emissions of the major greenhouse gases resulting from human activities, the concentrations of these gases in the atmosphere, and how emissions and concentrations have changed over time. When comparing emissions of different gases, these indicators use a concept called “global warming potential” to convert amounts of other gases into carbon dioxide equivalents."II.OPINION
The Green house effect the climate change a lot,also they will have 5 different kinds of unexpected effects of global warming.
First the price of everyday goods goes up: Framing land has been affected by low snowfall and high temperatures, which has affected crops such as corn and soybeans and the production of dairy products and meat. Than the price of the meat, corn, and soybeans will go up.
Third the disease has increased:as temperatures continue to rise, insects will migrate to warmer areas, and some diseases will follow. Fourth allergies have become more serious: as the amount of carbon dioxide in the air increases, plants that contain pollen will produce more pollen, increasing the amount to three to four times.
Fifth it will be difficult to breathe: the air in the city is mixed with automobile exhaust, industrial pollution and hot gas, and the air quality will be worse. Any smoke can worsen the health condition and affect the respiratory system, leading to chronic disease.So the Green house effect the climate change, and both give our Earth many big problem. As a result we need to solve those kinds of problem together as soon as possible.

Nice blog! I learned a lot of things about green house effect and how to protect the Earth better.
