Frequently Asked Questions
Is the current warming definitely caused by humans?
Yes, the scientific consensus is clear that human activities are causing current warming. The amount of warming corresponds to greenhouse gas increases from human activities. Models show natural factors alone cannot explain observed warming. Past ice ages and warm periods occurred from natural factors but current rapid warming is due to human greenhouse gas emissions.
Can the Earth cool on its own if we stop emitting greenhouse gases?
Once greenhouse gases are in the atmosphere, they persist for decades to centuries. Even if emissions stop today, warming will continue for decades as the atmosphere adjusts. Cooling would require removing greenhouse gases from the atmosphere, which is technologically and economically very difficult. This is why rapid emissions reduction is critical - every bit of emissions prevented now matters.
What can India do about climate change?
India can increase renewable energy sources like solar and wind. Improve energy efficiency in buildings and industry. Expand public transportation and electric vehicles. Protect and expand forests and mangroves. Develop climate-resilient agriculture. Support climate research and innovation. Provide climate adaptation assistance to vulnerable populations. Participate in international climate efforts. Every action reduces emissions and builds resilience.
