What is mean by global climate change?

Question

Please give SHORT DEFINITION answer in English and if possible, give in Marathi.

Answer 1

Some gases ("greenhouse gases") let sunlight in, which warms the Earth, and then block that heat from leaving. That's the "greenhouse effect", and it's a natural thing, mostly caused by water vapor.

Man is making excessive amounts of greenhouse gases, mostly by burning fossil fuels. That causes the delicate natural balance to go out of whack and the Earth warms. That's global climate change.

It won't be a Hollywood style disaster. Gradually coastal areas will flood and agriculture will be damaged. But it will be very bad. Rich countries will cope, but it will take huge amounts of money. In poor countries many people will die of starvation, but not all of them.

Most scientists say, in 20-50 years. But we need to start right now to fix it, fixing it will take even longer than that.

Answer 2

Climate change refers to the variation in the Earth's global climate or in regional climates over time. It describes changes in the variability or average state of the atmosphere over time scales ranging from decades to millions of years. These changes can be caused by processes internal to the Earth, external forces (e.g. variations in sunlight intensity) or, more recently, human activities.
In recent usage, especially in the context of environmental policy, the term "climate change" often refers only to changes in modern climate, including the rise in average surface temperature known as global warming. In some cases, the term is also used with a presumption of human causation, as in the United Nations Framework Convention on Climate Change (UNFCCC). The UNFCCC uses "climate variability" for non-human caused variations.

Answer 3

Climate change is a political philosophy made up to scare people into voting for them under the guise that they are the only ones who can protect us.

Here is a great quote about the nature of politics.

"The whole aim of practical politics is to keep the populace alarmed (and hence clamorous to be led to safety) by menacing it with an endless series of hobgoblins, all of them imaginary." [H. L. Mencken]

Answer 4

Ask Algore and he will sell you a carbon credit. Climate Change is a phoney problem that allows individuals with no marketable skills to shake down those of us that work in the name of saving the planet. Unelected and unaccountable UN bureaucrats will tell you and your family how to live while they ignore their own rules and live like kings from your money extorted from politicians and corporations too afraid to stand up to these envirogoons.
