Study: 2/3 of aviation climate impact due to emissions other than CO2

SEPTEMBER 6, 2020

It makes an important contribution to the scientific understanding we have of the role of aviation for climate change—an understanding decision-makers and politicians may need on the way to achieving the goals of the Paris Agreement. This new study is based on a thorough review of a decade of research on aviation emissions.

KIT study finds extraordinarily cold Arctic stratospheric winter enhanced ozone degradation above the Arctic

Extraordinarily cold temperatures in the stratosphere during the winter of 2010/2011 caused the most massive destruction of the ozone layer above the Arctic so far, according to a study by climate researchers at KIT (Karlsruhe Institute of Technology). Their paper appears in the journal Geophysical Research Letters.

NASA-led study identifies unprecedented depletion of stratospheric ozone layer above Arctic

OCTOBER 2, 2011

A NASA-led study has documented an unprecedented depletion of Earth’s protective ozone layer above the Arctic last winter and spring caused by an unusually prolonged period of extremely low temperatures in the stratosphere. The same ozone-loss processes occur each winter in the Arctic.

The climate change benefit is estimated for 2050 and human health and crop benefits are for 2030 and beyond. Black carbon and tropospheric ozone are harmful air pollutants that also contribute to climate change. Click to enlarge. Both near-term and long-term strategies are essential, the report concludes.

EPA says methane emissions from natural gas production have dropped 36% from 2007-2011

In its recently released Inventory of US Greenhouse Gas Emissions and Sinks: 1990 – 2011 ( earlier post ), the US Environmental Protection Agency (EPA) reported that methane (CH 4 ) emissions from the field production of natural gas have declined by 36% from 2007 to 2011 (from 83.1 Tg CO 2 eq) in 2011.

Circle areas are proportional to values for (A and B) climate change, (C and D) human health (values for population over age 30), and (E and F) agriculture. Methane is both a potent greenhouse gas and an important precursor to ground-level ozone. National benefits of the CH 4 plus BC measures versus the reference scenario.

The MIT group paid especially close attention to how changes in emissions caused by policy translate into improvements in local and regional air quality, using comprehensive models of both the economy and the atmosphere. In 2011, 231 counties in the US exceeded the EPA’s regulatory standards for ozone, the main component of smog.

Aviation climate change impacts pathway. In the months following a pulse of NO x in the upper atmosphere, ozone production is stimulated causing a short-term warming. The corresponding reduction in CH 4 , which is an important ozone precursor, leads to a long-term reduction in ozone. Credit: ACS, Stratton et al.
