<h1>Global carbon budget for 1.5^0C warming limit will be exhausted within three years at current emission rates</h1> Scientists warn that at current emission rates, the global carbon budget for limiting warming to 1.5 degrees Celsius will be exhausted within three years. The carbon budget for 2 degrees Celsius could be exceeded by 2048. Human activities release approximately 53 billion tonnes of carbon dioxide annually, primarily from fossil fuel burning and deforestation. Earth's temperature has risen 1.24 degrees Celsius above pre-industrial levels over the past decade, with 2024 being the hottest year recorded. A meteorological organization projects 70 percent probability that 2025-2029 average temperatures will exceed 1.5 degrees above pre-industrial baselines.
