Earth’s love-hate relationship with carbon dioxide

At last month’s international Pint of Science Festival, the Grantham Institute co-sponsored three events themed around Planet Earth. SSCP DTP student Rachel Bertram, who organised several of the talks, summarises some of the discussions about carbon dioxide, the most well-known greenhouse gas. Over a few nights each May, Pint of Science brings scientists out of their universities and research environments to the local pub where they … Continue reading Earth’s love-hate relationship with carbon dioxide

How can we generate a hundred per cent renewable electricity?

Charlie Cook, a student on the first cohort of Imperial’s new MSc in Climate Change, Management and Finance, checks on the roadmap leading to a world with electricity generated from a hundred per cent renewable sources. If you don’t know where you’re going, any road will take you there; Lewis Carroll’s Cheshire Cat points out to Alice. The Paris Agreement has set our sights on a … Continue reading How can we generate a hundred per cent renewable electricity?

Peering into the emissions gap

Grantham Affiliate Dr Heather Graven gives us the lowdown on the emissions gap. What is the emissions gap? The international community agreed on a 2°C target for the upper limit on global average temperature rise at the Conference of the Parties to the United Nations Framework Convention on Climate Change in Cancun in 2010 (COP16). The emissions gap is the difference between pledges made this … Continue reading Peering into the emissions gap

Apollo has landed: the role of the private sector in completing the race for 100% renewables

China’s carbon intensity reductions continue

By Ajay Gambhir A fortnight ago a journalist at New Scientist asked me if I’d seen the latest report by the Netherlands Environment Assessment Agency (PBL) and Joint Research Centre (JRC) on last year’s global CO2 emissions figures. He wanted some quick reactions on analysis that showed China’s emissions per unit of economic output (its “emissions intensity”) had declined by over 4% in 2012, compared … Continue reading China’s carbon intensity reductions continue
