Climate is the condition of weather on day to day basis over a period of 30 years. A region's climate is generated by theclimate system, which has five components:atmosphere,hydrosphere,cryosphere,lithosphere, andbiosphere.

It is measured by studying the patterns of changes occurring intemperature,humidity,atmospheric pressure,wind,precipitation, atmospheric particle count in a given region over long periods of time.

Climate is different from weather as, weather only describes the short term details of such variables.

Over the past years, we have seen major climatic changes.Climate changeoccurs when changes in Earth's climate system result in newweatherpatterns that last for at least a few decades, and maybe for millions of years.

Human activities have caused changes in the climate system of the earth. The population for its benefit undertakes such activities that possess a threat to the climate for a region.

One of the major causes of the climatic change or increased global warming is the emission of greenhouse gases due to human activities.

Greenhouse gases trap heat and make the planet warmer. Human activities are responsible for almost all of the increase in greenhouse gases in the atmosphere over the last 150 years.

Carbon dioxide from the burning of fossil fuels is the largest single source of greenhouse gas emissions from human activities. Extracting, processing, transporting, and distributing fossil fuels also releases greenhouse gases.

Deforestation is the second largest source of carbon dioxide.
Industry creates chlorofluorocarbons (CFCs) and other halocarbons for use in various products and industrial processes which again is dangerous for the environment.

However times have begun to change and more and more people are are taking steps to reduce their part of destruction to the environment.

From Bangkok to Berlin, thousands of school students from 123 countries and over 2,000 cities all over the world go on strike against government inaction on climate change.

In London, thousands of students marched from Parliament Square to Trafalgar Square holding banners that read: "The future is in our hands" and "We're missing lessons to teach you one".

More than 220 demonstrations were held across Germany. In Duesseldorf, more than 2,000 schoolchildren marched with a carnival float depicting a giant effigy of Thunberg with the words "Do something about the climate catastrophe at last," written along her raised arms.

We won’t want to live in a place that is suffocating, then why are we causing the same suffocation for our Earth?

One person cannot make a huge change, but what matters is one person can make a change.
Realise your duty, and do something about it.
