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

Green Car Congress

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. 2 (5–95% likelihood range of (55, 145)) with major contributions from contrail cirrus (57.4?mW?m

Black carbon is a much larger cause of climate change than previously assessed; about twice previous estimates, and 2/3 the effect of CO2

Green Car Congress

Accounting for all of the ways black carbon can affect climate, it is believed to have a warming effect of about 1.1 Emission rates of BC in the year 2000 by region, indicating major source categories in each region. Black carbon aerosol plays a unique and important role in Earth’s climate system. W m -2 range).

Study projects thermoelectric power in Europe and US vulnerable to climate change due to lower summer river flows and higher river water temperatures

Green Car Congress

Projected changes in summer mean usable capacity of power plants in the US and Europe for the SRES A2 emissions scenario for the 2040s (2031–2060) relative to the control period (1971–2000). A study published in Nature Climate Change suggests that thermoelectric power plants (i.e., Source: van Vliet et al. Michelle T.

PwC: Global Carbon Budget For 2000-2050 Could Be Exhausted By 2034

Green Car Congress

Global accounting firm PricewaterhouseCoopers has analyzed carbon emissions from 2000 to 2008 and concluded that the world’s “carbon emissions budget”, or ability to emit carbon dioxide while still maintaining a “fair chance” of limiting average global temperatures to no more than 2 ºC (3.6 Click to enlarge.

Cutting Non-CO2 Pollutants Can Delay Abrupt Climate Change; The Fast Action Climate Agenda

Green Car Congress

Shown are the tipping elements [large-scale components of the Earth’s system] and the temperature threshold range that initiates the tipping. The Montreal Protocol has already delayed climate change by seven to 12 years, and put the ozone layer on the path to recovery later this century. From Molina et al. Madhava Sarma.
