Greenhouse Gas Emissions Up 7.8% in Brazil in 2013
2014-11-20 06:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Herald Tribune: Greenhouse gas emissions in Brazil amounted to 1.5 million tons in 2013, up 7.8 percent from 2012 and the highest total since 2008, non-governmental organizations said in a report released on Wednesday. The study by the Climate Observatory mainly attributes the increase in emissions to Amazon deforestation, increased use of thermoelectric plants and greater fuel consumption. Emissions from deforestation accounted for 35 percent of the total, followed by those from the electricity and agricultural...
NASA findings show no excessive methane emissions from Alaska

Anchorage Dispatch: Though Arctic Alaska is warming and permafrost is thawing, the area so far has been spared from the scourge of excessive methane emissions, according to data collected by a NASA-managed research project. Concentrations of methane measured in the atmosphere over Alaska from May to September 2012 -- the first of five seasons for NASAs Carbon in Arctic Reservoirs Vulnerability Experiment, or CARVE -- turned out to be about equal to the global average for a similar-sized area. The findings, gleaned...

Nasa animation shows stunning year in life of carbon emissions
2014-11-19 13:58:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: This is what your atmosphere looks like in carbon dioxide (CO2). And its not a pretty sight. Nasa provides a stark and stunning view of a year in the life of our planet as humans continue to emit greenhouse gases that warm the planet. The animation comes courtesy of one of the highest-resolution computer models in existence. Since the industrial revolution, CO2 has been rising in the atmosphere due to human activities. Seasonal cycles mean that CO2 rises progressively throughout autumn and winter...

At This Rate, World Will Have to Cease All Carbon Emissions in 2040 to Stay Under 2°C
2014-11-18 06:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Think Progress: By 2040, the world will emit all the carbon it can afford while remaining within safe ranges of climate change, according to a report released last week. Scientists and policymakers have generally settled on 2°C as the amount of global temperature increase, over pre-industrial levels, the climate can take without creating truly dangerous upheavals. Because the effect of carbon in the atmosphere is cumulative, staying below that threshold requires a hard limit on the amount of carbon the world emits...
Ending deforestation won't stop carbon emissions from land use change

Mongabay: Even if the world stopped cutting down forests, carbon dioxide emissions from land use change would still pose a major challenge, according to a new paper in Nature Climate Change. The research finds that eliminating deforestation would mean agriculture would be pushed into non-forest ecosystems and still release significant quantities of carbon dioxide. "While protecting forests to abate climate change is definitely worthwhile, our results illustrate for the first time that forest protection...
