Scientists call for careful use of time scales, reference dates and statistical approaches in analyzing climate change trends to avoid distortion and hampering of response

Green Car Congress

Demonstrating that the use of different time scales, reference dates, and statistical approaches can generate highly disparate results in climate reports, scientists at the University of Alaska Anchorage argue that careful use of these tools is critical for correctly interpreting and reporting climatic trends in Alaska and other polar regions.

Study measures the effect of regional change in clouds caused by ships’ emissions; masking GHG warming

Green Car Congress

New research led by the University of Washington (UW) is the first to measure this phenomenon’s effect over years and at a regional scale. The authors compared cloud properties inside the shipping route with an estimate of what those cloud properties would have been in the absence of shipping based on statistics from nearby, unpolluted areas.

New inventory of black carbon emissions from China finds 2007 levels higher than previously reported

Green Car Congress

The paper by researchers from Peking University and Environment Canada appears in the ACS journal Environmental Science & Technology. Black carbon is released into the atmosphere via incomplete combustion of carbonaceous fuel and is of major concern because of the impact on climate systems. Earlier post.). Earlier post.).

Colorado State University Forecasters Predict Above-Average 2010 Hurricane Season

Green Car Congress

The Colorado State University forecast team predicts an above-average 2010 Atlantic basin hurricane season based on the premise that El Niño conditions will dissipate by this summer and that anomalously warm tropical Atlantic sea surface temperatures will persist. The team began using a new early April statistical model in 2008.

Study finds some improved cookstoves may emit more black carbon pollution than traditional mud cookstoves

Green Car Congress

The first real-world, head-to-head comparison of improved cookstoves (ICs) and traditional mud stoves has found that some ICs may at times emit more of the black carbon particles that are linked to serious health and environmental concerns than traditional mud stoves or open-cook fires.

Study finds rising temperatures increase risk of unhealthy ozone levels absent sharp cuts in precursors

Green Car Congress

The RCPs were chosen to represent a broad range of climate outcomes, based on a literature review. Warmer temperatures and other changes in the atmosphere related to a changing climate, including higher atmospheric levels of methane, spur the chemical reactions that lead to ozone. The RCP 8.5 Supercomputing.
