Harmful doses of greenhouse gases that
are released into the atmosphere traps the
sun's heat, causing rising temperatures

Even if Global Warming has started, that doesn't mean we can't stop it. To quote UN | ActNow:

"Climate action is a task for all of us. Concrete steps need to be taken by all sectors of society – first and foremost by governments, businesses and industry. Speak up! Appeal to world leaders, urge your city, your bank and your employer to take urgent action toward net-zero emissions"

"Much of our electricity and heat are still powered by coal, oil, and gas.
Airplanes and cars also run mostly on fossil fuels. To reduce your carbon footprint,
use less energy at home, switch to a wind or solar-energy provider,
skip a long-haul flight, and drive less"

"The production, processing, transport, consumption,
and disposal of food all contribute to greenhouse-gas emissions.
To reduce your impact on the climate, buy local and seasonal food,
eat more plant-based meals, use up what you have, and compost any leftovers"
