Growing Arctic carbon emissions can go unobserved

A new NASA-led study has found that in at least part of the Arctic, scientists are not doing as good a job of detecting changes in carbon dioxide during the long, dark winter months as they are at monitoring changes during the short summer. That's a concern, because growing Arctic plants can act as a brake on global warming rates by removing carbon from the atmosphere, but increasing cold-season emissions could overwhelm the braking effect and accelerate global warming.

Wind technologies: Opportunities and barriers to a low carbon shipping industry

A recent study reveals that the abatement potential of wind technologies on ships is estimated to be around 10–60% by various sources. To date there has been minimal uptake of this promising technology, despite a number of commercially available solutions that have been developed to harness this free and abundant energy source. Several barriers have been referred to in the literature that inhibit uptake of energy efficiency measures in shipping.

Carbon emissions to decline after 2030

ExxonMobil’s new report ''The Outlook for Energy: A view to 2040'' forecasts that global CO2 emissions are likely to peak around 2030, and then begin declining. In coming decades, although populations and living standards will rise significantly, ongoing improvements to energy efficiency – and increasing efforts to use lower-carbon fuels wherever practical – will slow the growth in energy-related CO2 emissions.
