Answer:

hey mate here's my answer

Explanation:

Global warming is the temperature of Earth's surface, oceans and atmosphere going up over tens of years.[1] Average temperatures today are about 1 °C (1.8 °F) higher than before the Industrial Revolution, which started around 1750.[2] But in some parts of the world it is less than this and some more. Almost all scientists say that by the year 2100 temperatures will be 1.5 °C (2.7 °F) to 5 °C (9.0 °F) higher than they were before 1750.[3] The most noticeable changes because of this increase in temperature is the melting of ice caps all around the world. Sea level is rising steadily because of continental ice melting into the sea. Many cities will be partly flooded by the ocean in the 21st century.

Among the greenhouse gases, the increase of carbon dioxide in the atmosphere is the main cause of global warming, as predicted by Svante Arrhenius a hundred years ago, confirming the work of Joseph Fouriermore than 200 years ago. When people burn fossil fuels like coal, oil and natural gas this adds carbon dioxide into the air

The gas produced by cows digestion also causes global warming, because it contains a greenhouse gas called methane.

Explanation:

Global Warming is the long term rise in the average temperature of the Earth's climate system. It is a major aspect of current climate change and has been demonstrated by direct temperature measurements and by measurements of various effects of the warming.

The effects of global warming include rising of sea levels, regional changes in precipitation,more frequent extreme weather events such as heat waves and expansion of deserts .Surface temperature increases are greatest in the attic ,which has contributed to the retreat of glaciers , permafrost and sea water.Overall, higher temperatures bring more rain and wildfires increases instead . Climate change threatens to diminish crop yields , harming food security and rising sea level may flood coastal infrastructure and force the abdoment of many coastal cities. Because the climate system has a large inertia and greenhouse gases persist in the atmosphere,climatic changes and their effects will continue for many centuries even if green house gas emissions are stopped.

The main driver of today's warming is the combustion of fossil fuels. These hydrocarbons heat up the planet via the green house effect , which is caused by the interaction between Earth's atmosphere and incoming radiation from the sun

Slogans :

1) Destroy global warming before it destroys you

2) Global warming has one solution , everyone just stop POLLUTION

3)Try to reduce global warming or be ready to fry in future.
