Global warming, we need to take action against it.

Climate experts are formal : the earth is warming up at a steady pace. The reason for this is the increase in human-caused greenhouse gases, which has led to health, ecological and humanitarian crises.

Global warming is projected to have a number of effects on the oceans and our health as well. Ongoing effects include rising sea levels due to thermal expansion and melting of glaciers and ice sheets, and warming of the ocean surface, leading to increased temperature stratification.

As the climate warms, it chages the nature of global rainfall, evaporation, snow, stream flow and other factorwes that affect supply and quality. Specific impacts include: warmer water temperature affect water quality and accelerate water pollution. 

Melting glaciers, early snowmelt, and severe droughts will cause more dramatic water shortage and increase the risk of wildlife in the American West. Increasing sea levels will lead to coastal flooding on the Eastern Seaboard, especially in florida, and in other areas such as the Gulf of Mexico.

Forests, farms, and cities face troublesome new pests, het waves downpours, and inc reased flooding. All those factors wil damage or destroy agriculture and fisheries.

Disruption of habitats such as coral reefs and Alpine meadows could drive many plant and animals species to extinction which can affect humans negatively.

Allergies, asthama, and infectious  disease outbreaks will become more common due to increased growth of pollen- producing ragweed, higher levels of air pollution, and the spread of conditions favorable to pathogens and mosquitoes.

Globally, at the United Nations Conference on climate change in Paris, 195 countries- including United Sates, at the time- agreed to pollution cutting provisions with a goal of preventing the global temperature from rising more than 1.5 degrees celsius above preindustrial times.

However, some contries are now trying to reduce gas emission including china, india, australia and u.s. and takes positives step to deal with this issue.
