Answers
Answer: It occurs as a result of an increased concentration of greenhouse gases in the atmosphere. The greenhouse gases include carbon dioxide, methane, and water vapour. These gases trap solar radiations released back by the Earth. This helps in keeping our planet warm and thus, helps in human survival.

Answer:
For too long, methane has often been left out of the climate conversation. In fact, it is one of the many causes of climate change, with levels of atmospheric methane now at an all-time high since the 1980s despite the economic slowdown from COVID-19, according to preliminary estimates by the US National Oceanic and Atmospheric Administration (NOAA) in April 2020. But even as a growing number of climate scientists, experts, and policymakers recognise the dire need to reduce methane emissions as a crucial aspect in preventing a widespread environmental catastrophe, recent findings have shown that there is no better time to act than the present. A recently published study has indicated that implementing rapid, full-scale efforts to cut down global methane emissions using existing technologies could slash such emissions in half and slow the current rate of Earth’s climate warming by as much as 30% by 2030.
