Question

What is Global Warming. Didi please answer it. ​

Answer 1

Answer:

Climate change includes both global warming driven by human-induced emissions of greenhouse gases and the resulting large-scale shifts in weather patterns.

Answer 2

Answer:

Global warming is the temperature of Earth's surface, oceans and atmosphere going up over ten to thousands of years. Average temperatures today are about 1 °C (1.8 °F) higher than before people started burning a lot of coal around 1750. But in some parts of the world it is less than this and some more. Most climate scientists say that by the year 2100 temperatures will be 2 °C (3.6 °F) to 4 °C (7.2 °F) higher than they were before 1750. The changes people can see most easily is because of this increase in temperature is the melting of ice caps all around the world. Sea level is rising for two reasons. One reason is because of ice on the land, like Greenland, melting into the sea. The other reason is because of water getting bigger when it gets warmer. Many cities will be partly flooded by the ocean in the 21st century.

Global warming is a culmination of unsustainable human activities on the globe. Most entities have put a considerable amount of focus on their bottom line as opposed to care for the environment. Reversing the impact of climate change would need people to rethink how they conduct their activities contemporaneously with a view of safeguarding the globe for the current and future generation. Global warming is mostly because of people burning things, like gasoline to make cars go and natural gas to keep houses warm. But the heat from the burning itself only makes the world a tiny bit warmer: it is the carbon dioxide from the burning which is the biggest part of the problem. 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 Fourier more than 200 years ago. When people burn fossil fuels like coal, oil and natural gas this adds carbon dioxide into the air. This is because fossil fuels contain lots of carbon and burning means joining most of the atoms in the fuel with oxygen. When people cut down many trees (deforestation), this means less carbon dioxide is taken out of the atmosphere by those plants.

As the Earth's surface temperature becomes hotter the sea level becomes higher. This is partly because water over 4 °C (7.2 °F) expands when it gets warmer. It is also partly because warm temperatures make glaciers and ice caps melt. The sea level rise causes coastal areas to flood. Weather patterns, including where and how much rain or snow there is, are changing. Deserts will probably increase in size. Colder areas will warm up faster than warm areas. Strong storms may become more likely and farming may not make as much food. These effects will not be the same everywhere. The changes from one area to another are not well known. People in government and the Intergovernmental Panel on Climate Change (IPCC) are talking about global warming. But governments, companies, and other people do not agree on what to do about it. Some things that could reduce warming are to burn less fossil fuels, grow more trees, eat less meat, and put some carbon dioxide back in the ground. Shading the Earth from some sunlight (this is called geoengineering) could also reduce warming but we don't understand how it might change weather in other ways. Also people could adapt to any temperature changes. The Kyoto Protocol and Paris Agreement try to reduce pollution from the burning of fossil fuels. Most governments have agreed to them but some people in government think nothing should change. The gas produced by cows digestion also causes global warming, because it contains a greenhouse gas called methane.

I hope this answer helps you ☺.
