Researchers in France have found that ozone depletion above Antarctica has significantly reduced the Southern Ocean’s ability to absorb atmospheric CO 2 and has also accelerated acidification of southern polar waters, despite lesser CO 2 uptake. The results revealed that, between 1987 and 2004, around 2.3 Lenton, A., Tagliabue, and J.

Started in 2004, the AGGI reached 1.29 This is slightly higher than the 2009 AGGI, which was 1.27—i.e., It also includes several chemicals known to deplete Earth’s protective ozone layer, which are also active as greenhouse gases. Methane measured 1794 ppb in 2009, and 1714 ppb in 1990. in 2010—i.e.,

This could explain satellite measurements showing high levels of stratospheric ozone, water vapor and other chemicals over Asia during summer. Satellite records from 2004 to 2009 showed a pattern of increases in the chemical’s presence in the stratosphere each summer, correlating with the timing of the monsoon.

The on-road transportation (ORT) and power generation (PG) sectors are major contributors to CO 2 emissions and a host of short-lived radiatively-active air pollutants, including tropospheric ozone and fine aerosol particles, that exert complex influences on global climate. 2009) Click to enlarge.

Significant climate anomalies 2008/2009. A new climate modeling system, forecasting average temperatures over a decade by combining natural variation with the impacts of human-induced climate change, projects that at least half of the 10 years following 2009 will exceed the warmest year currently on record.

Many of the strategies employed to reduce GHG emissions will also work to meet the national ambient air quality standard for ozone in 2032. California’s vehicle GHG standards—authorized by AB 1493 (Pavley) in 2002, first approved in 2004, and extended in 2012—are delivering fuel consumption and CO 2 reductions.
