大气二氧化碳达到430 ppm,在人类活动驱动下,至少3 000万年中创历史新高。 Atmospheric CO2 reaches 430 ppm, a record high in at least 30 million years, driven by human activities.

根据NOAA和UC San Diego的数据,大气二氧化碳含量创历史新高,达到百万分之430(ppm),是至少3 000万年中的最高水平。 Atmospheric CO2 levels have hit a record high of 430 parts per million (ppm), the highest in at least 30 million years, according to data from NOAA and UC San Diego. 这一增加主要是由于人类活动,如燃烧化石燃料,比去年的记录高出3ppm以上。 This increase, primarily due to human activities like burning fossil fuels, surpasses last year's record by more than 3 ppm. 如果趋势继续下去,今后30年的水平可能会达到500ppm,从而导致全球变暖和气候变化。 If trends continue, levels could reach 500 ppm in the next 30 years, contributing to global warming and climate change.
