Fight fiercely, Harvard, against global warming, alumnus says

Sydney Morning Herald: 'Fight fiercely, Harvard', a favorite college's song, doesn't seem to apply to climate change, an alumnus says. More than 40 years ago, as a Harvard sophomore, I sat in the classroom of Professor Roger Revelle, who was teaching a course on human population. We learned about Malthus, Norman Borlaug and the green revolution. Revelle, in his heavily stained necktie, would entertain us with mental calculations he'd performed while taking a shower earlier in the morning. Over the course of the semester,...

No Quick Fix For Global Warming
2014-11-05 19:19:00| Climate Ark Climate Change & Global Warming Newsfeed
RedOrbit: When fossil fuels are burned, other climate-forcing gases are produced in addition to long-lasting carbon dioxide. Diesel combustion in vehicles or coal in power plants creates soot particles, which also contribute to global warming, albeit only briefly as they disappear quickly from the atmosphere. Short-lived climate pollutants (also known as Short Lived Climate Forcers or SLCF) caused by human activities include methane and sulphur dioxide, and to a lesser extent fluorocarbons. They all have a...

Climate change: no quick fix for global warming 'without cutting down carbon emissions'

Business Times: Short-term fixing of the global climate will not help, says a new interdisciplinary study by showing how long-term emissions of carbon dioxide and short-lived climate pollutants like methane and sulphur dioxide are related. Soot particles, methane and fluorocarbons originating from fossil fuels, coal mines, cows and diesel engines are called short-lived climate forcers (SLCF) due to their brief lifetime of a few days to a decade. On the other hand carbon dioxide lasts thousands of years in...
India: Warming signals

Indian Express: Attitudes toward climate change in India can appear paradoxical. Although India is one of the countries most deeply vulnerable to climate impacts, climate change does not rank high on policymakers list of concerns. Two factors explain this inattention. First, India has pressing and immediate development concerns, such as providing sanitation, improved healthcare and access to affordable energy to its population, while the effects of climate change appear abstract and distant. Second, there is a...

Cutting Methane, Soot Not Enough to Tackle Warming
2014-11-04 22:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate Central: If the race to warm the planet were a children's allegory, carbon dioxide would be considered the tortoise, while soot and methane would play the role of the hare. In reality, as in fairy tales, the tortoise is going to win. Recent focus on targeting methane, soot and other short-term pollutants to combat climate change is not going to keep global warming in check if CO2 is not also slashed to stop its long-term impact, a new study says. The research, published this week in the Proceedings...
