Global warming ka apekshit parinaam hai

Scientists from around the world serve as part of the Intergovernmental Panel on Climate Change (IPCC). These scientists have found that from 1900-2020, the world's surface air temperature increased an average of 1.1° Celsius (nearly 2°F) due to burning fossil fuels that releases carbon dioxide and other greenhouse gases into the atmosphere. This may not sound like very much change, but this warming is unprecedented in over 2000 years of records. Even one degree can impact the planet in many ways. Climate models predict that Earth's global average temperature will rise an additional 4° C (7.2° F) during the 21st Century if greenhouse gas levels continue to rise at present levels. Without swift action to reduce greenhouse gas emissions, models project that holding global average temperatures to within a 1.5-2.0°C (2.7-3.6°F) increase may no longer be possible. The amount of climate change by the end of the century depends on decisions we make today. If we reduce CO 2 amounts to stop increasing after 2050, global average temperature will increase from 1-1.5°C, and this is considered a best case scenario (blue line in graph). If we don’t reduce CO 2 and the amounts continue to increase, the worst case scenario warming will be 4.5-5°C (red line in graph). IPCC Working Group I, 2021 Predicted Impacts of Climate Change Warming is already occurring in all areas of the globe, but models of future temperatures show that the changes will not be distributed equally.
