Global warming is an aspect of climate change, referring to the long-term rise of the planet's temperatures. It is caused by increased concentrations of greenhouse gases in the atmosphere, mainly from human activities such as burning fossil fuels, deforestation and farming.

The history of science is the study of the development of science, including both the natural and social sciences. Science is a body of empirical, theoretical, and practical knowledge about the natural world, produced by scientists who emphasize the observation, explanation, and prediction of real-world phenomena.

Human activities are substantial reason for climate change because:

Human activities, particularly the combustion of fossil fuels, are altering the climate system.

Human-driven changes in land use and land cover such as deforestation, urbanization, and shifts in vegetation patterns also alter the climate, resulting in changes to the reflectivity of the Earth surface (albedo), emissions from burning forests, urban heat island effects and changes in the natural water cycle.

Because the primary cause of recent global climate change is human, the solutions are also within the human domain.

Science knows no country, because knowledge belongs to humanity, and is the torch which illuminates the world-Louis Pasteur

The most beautiful thing we can experience is the mysterious. It is the source of all true art and science-Albert Einstein

Science without religion is lame, religion without science is blind-Albert Einstein

An experiment is a question which science poses to Nature and a measurement is the recording of Nature's answer-Max Planck

One machine can do the work of fifty ordinary men. No machine can do the work of one extraordinary man-Elbert Hubbard

Humankind has the science and technology to destroy itself or to provide prosperity for all. But while science offers us these opportunities, science will not make that choice for us. Only the moral power of a world acting as a community can-Margaret Beckett

Human activity is the substantial reason for climate change, yes because we cut tress( deforestation) fossil fuels water conservation... This day is founded by  Sir C raman on 28th February 1928. We humans are also a very big factor for climatic change

Deforestation plays an important role in global warming and climatic changes. Planting trees is helpful as they absorb carbon dioxide from the atmosphere and regulate the climate. Hence, there is a dire need to plant more trees because a single tree can absorb one ton of CO₂ in its lifetime.

Switch to renewable energy

One of the most effective ways to prevent global warming is to start using renewable energy sources such as solar, geothermal, wind and biomass, and stop using fossil fuels. Use renewable energy resources to supply power to your home.

Use energy-efficient devices

By investing in energy-efficient devices such as bulbs, LED lights or solar-powered shower system, you can reduce the energy consumption and help in the production of clean energy. It is not only the cheapest way to reduce greenhouse gas emissions but it also reduces the amount of carbon dioxide released in the atmosphere.

Spread awareness

Speak up about global warming, its consequences, causes and what steps we can take to prevent global warming with your friends, family and colleagues. Use the power of social media to voice out your concerns about climate change.

Save water

Make sure to turn off taps while brushing, go for shorter showers and do not waster water by cleaning your cars or bike

National Science Day is celebrated in India on 28 February each year to mark the discovery of the Raman effect by Indian physicist Sir C. V. Raman on 28 February 1928. For his discovery, Sir C.V. Raman was awarded the Nobel Prize in Physics in 1930. National Science Day is celebrated to spread a message about the importance of science used in the daily life of the people. To display all the activities, efforts and achievements in the field of science for human welfare. It is celebrated to discuss all the issues and implement new technologies for the development in the field of science. To give an opportunity to the scientific minded citizens in India. To encourage the people as well as popularize science and technology.

Humans are increasingly influencing the climate and the earth's temperature by burning fossil fuels, cutting down rainforests and farming livestock.

human activities have released increasing quantities of greenhouse gases into the atmosphere. This has led to increases in mean global temperature, or global warming.

Human activity is substantial reason for climate change

Burning of plastics and the smoke released from the factories damage the ozone layer which protects the earth from more heat and protects humans from diseases caused due to sun when the ozone layer gets damaged it leads to the increase of temperature which makes the melting of icebergs which increases the level of sea water

Humans are increasingly influencing the climate and the earth's temperature by burning fossil fuels, cutting down rainforests and farming livestock.

This adds enormous amounts of greenhouse gases to those naturally occurring in the atmosphere, increasing the greenhouse effect and global warming.

In 1986, the National Council for Science and Technology Communication (NCSTC) asked the Government of India to designate February 28 as National Science Day. The event is now celebrated all over India in schools, colleges, universities and other academic, scientific, technical, medical and research institutions. On the occasion of the first NSD (National Science Day)(28 February 1987) NCSTC announced the institution of the National Science Popularization awards for recognizing outstanding efforts in the area of science and communication.
