研究报告:全球控温1.5摄氏度目标不易实现
Core Insights - A study involving top global scientists predicts that human activities will lead to a 1.5°C increase in global average temperatures by early 2028, making it difficult to achieve the temperature control goals set by the Paris Agreement [1][3] - The report published in the journal "Earth System Science Data" indicates that at the current rate of 42 billion tons of CO2 emissions per year, there is a 50% chance of reaching the 1.5°C threshold by February 2028 [1][3] - The speed of greenhouse gas emissions is accelerating faster than previously predicted, raising concerns about the worsening climate situation [3] Emission and Temperature Projections - According to the Paris Agreement, parties aim to limit the increase in global average temperature to well below 2°C above pre-industrial levels, with efforts to limit the increase to 1.5°C [3] - The imbalance between heat absorption and release on Earth is intensifying, which is alarming according to the report's lead author [3] Implications of Temperature Increase - Experts warn that surpassing the 1.5°C threshold will lead to more frequent and severe extreme weather events [5] - While crossing the 1.5°C mark does not signify an apocalyptic scenario, every 0.1°C increase in average temperature will result in worse impacts [5]
