Potential contribution of wind energy to climate change mitigation

It is still possible to limit greenhouse gas emissions to avoid the 2 °C warming threshold for dangerous climate change. Here we explore the potential role of expanded wind energy deployment in climate change mitigation efforts. At present, most turbines are located in extra-tropical Asia, Europe and North America, where climate projections indicate continuity of the abundant wind resource during this century. Scenarios from international agencies indicate that this virtually carbon-free source could supply 10–31% of electricity worldwide by 2050.

The 'Solar Scam' and the siege at Thiruvananthapuram

41

The Communist Party of India (Marxist)-led Left Democratic Front had announced an indefinite siege of the Kerala state secretariat until the chiefminister owned responsibility for the "solar scam" and resigned. The calling off of this indefinitesiege within 30 hours raises a number of questions, including about the political conduct of the CPI(M) itself.

Trade-offs between mitigation costs and temperature change

This paper uses the MERGE integrated assessment model to identify the least-cost mitigation strategy for achieving a range of climate policies. Mitigation is measured in terms of GDP foregone. This is not a benefit-cost analysis. No attempt is made to calculate the reduction in damages brought about by a particular policy. Assumptions are varied regarding the availability of energy-producing and energy-using technologies. We find pathways with substantial reductions in temperature change, with the cost of reductions varying significantly, depending on policy and technology assumptions.
