Detailed explanation-1: -Scientific information taken from natural sources (such as ice cores, rocks, and tree rings) and from modern equipment (like satellites and instruments) all show the signs of a changing climate. From global temperature rise to melting ice sheets, the evidence of a warming planet abounds.
Detailed explanation-2: -Ice cores drawn from Greenland, Antarctica, and tropical mountain glaciers show that Earth’s climate responds to changes in greenhouse gas levels. Ancient evidence can also be found in tree rings, ocean sediments, coral reefs, and layers of sedimentary rocks.
Detailed explanation-3: -Heat waves’ frequency and intensity are increasing in India because of climate change. Severe landslides and floods are projected to become increasingly common in such states as Assam. Climate change performance index of India ranks eighth among 63 countries which account for 92% of all GHG emissions in the year 2021.
Detailed explanation-4: -Generating power. Generating electricity and heat by burning fossil fuels causes a large chunk of global emissions. Manufacturing goods. Cutting down forests. Using transportation. Producing food. Powering buildings. Consuming too much.
