Illustration of projected ozone changes in the South Coast region due to climate change in 2050. Areas in orange and red could see ozone concentrations elevated by 9 to 18 parts per billion. We already know that climate change will bring us increased forest fires, shorter winters, hotter summers and impact our water supply.
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
solar, wind, hydroelectric, and nuclear) as compared to the eastern US (EUS), where the electricity market is dominated by pollutant and precursor emitting combustion sources (i.e., Among the findings: Summer surface ozone (O 3 ) decreases in most locations due to widespread reductions of traffic NO x emissions. NH 3 -poor for PM).
They found that reductions in ground ozone during this 35-year period resulted in $600 million in increased production annually by the early 2010s. Another difference is that some grains can be annually modified to withstand greater heat and even higher ozone levels in the air. An open-access paper on the work appears in Nature Food.
Arrows denote winds at this level derived from meteorological analysis, showing that the HCN maximum is linked with the upper tropospheric Asian monsoon anticyclone. This could explain satellite measurements showing high levels of stratospheric ozone, water vapor and other chemicals over Asia during summer. Source: Randel et al.,
However, emissions do not just remain in conurbations; particles and gaseous pollutants can be transported thousands of kilometers by the wind. The transport and transformation of plumes from selected European and Asian major population centers (MPCs) will now be investigated with special focus on the rate of formation of ozone and aerosols.
Other notable highlights in the inventory include: For the first time since California started to track GHG emissions, in-state and total electricity generation from zero-GHG sources (for purposes of the GHG inventory, these include solar, hydro, wind, and nuclear) exceeded generation from GHG-emitting sources.
Markey of the Energy and Environment Subcommittee on Tuesday released a draft of far-reaching energy and climate legislation that targets job creation, promotes renewables and energy efficiency, and places limits on emissions of greenhouse gases. Waxman of the Energy and Commerce Committee and Chairman Edward J.
Health and other non-climate damages by life-cycle component for different combinations of fuels and light-duty automobiles in 2005 (top) and 2030 (bottom). Climate-related monetary damages range from 0.1 Estimated climate damages from natural gas were half that of coal, ranging from 0.05 Source: “Hidden Costs of Energy”.
Since 1990, there has been a 40% increase in total radiative forcing—the warming effect on the climate—by all long-lived greenhouse gases, and a 2.5% WMO is also striving to improve weather and climate services for the renewable energy sector and to support the Green Economy and sustainable development. parts per billion.
Eliza Strickland: Man-made climate change is already reshaping our planet, and carbon emissions aren’t coming down fast enough to stave off real disaster in the decades to come. It’s often called geoengineering in the popular press, but the preferred term is climate intervention. Transcript. Kelly Wanser : Thank you, Eliza.
Depletion of Antarctic ozone is a more important factor than increasing greenhouse gases in shifting the Southern Hemisphere jet stream in a southward direction, according to researchers at Penn State. Understanding the differences between these two forcings is important in predicting what will happen as the ozone hole recovers.
