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. Phil Klotzbach, lead forecaster on the CSU Hurricane Forecast Team.

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 anthropogenic precursor emission scenarios.

Study finds methane leaks from three large US natural gas fields in line with EPA estimates

Green Car Congress

CIRES is a partnership of NOAA and the University of Colorado Boulder. If leak rates are too high, natural gas does not compare favorably with one alternative, coal, in terms of climate impact. Where leak rates are low, the comparison favors natural gas. —co-author Joost de Gouw, a CIRES scientist who also works at NOAA.

Converting Oil Shale to Gasoline via Alberta Taciuk Processor Results in Full Fuel Cycle GHG Emissions 1.5-1.75 Larger Than From Conventionally Produced Gasoline

Green Car Congress

The largest global oil shale deposits—estimated to be equivalent to 1,500 Gbbl oil equivalent—are found in the Green River formation of Colorado, Utah, and Wyoming. For comparison, upstream consumption for reformulated gasoline produced from conventional oil is ~0.2-0.25 MJ upstream. MJ/MJ fuel.

Study on Greenhouse Gas Emissions from Global Cities Highlights Importance of Geophysical and Technical Factors

Green Car Congress

An international study of 10 global cities found that a balance of geophysical factors (climate, access to resources, and gateway status) and technical factors (power generation, urban design, and waste processing) determine the greenhouse gas emissions (GHGs) attributable to cities. Timothy Hillman, University of Colorado.

Road Test: 2021 GMC Sierra 1500 Duramax 4WD Crew Cab AT4 CarbonPro

Clean Fleet Report

The power rear sliding window and power sunroof were nice features, along with the wireless charger for mobile phones, dual zone climate control and leather-wrapped, heated steering wheel with audio and cruise controls. About those radio knobs and the climate control wheels: they are constructed using a cheap-feeling chromed plastic.

Study casting doubt on GHG benefits of corn stover ethanol draws sharp criticism by other researchers; Liska responds

Green Car Congress

A study published earlier this year in the journal Nature Climate Change that cast doubt on whether biofuels produced from corn residue could meet federal mandates for cellulosic biofuels to reduce greenhouse gas emissions by 60% compared to gasoline ( earlier post ) has drawn critical response published as correspondence in the same journal.
