Overcoming The North-South Divide in Climate Change Research and Policy

by Claudia Chandra

Nature Climate Change published a research paper in January 2017 by Malgorzata Blicharska and her associates from countries including Brazil, Kenya, Sweden, South Africa and India. The paper discusses the global North-South divide in climate change research, policy and practice, which originates from the Southern countries’ smaller capacity to undertake research. Countries are categorized into either “Northern” (members of the Organization for Economic Cooperation and Development such as Europe, North America, East Asia and Australasia) or “Southern” (lower income economies such as Asia, Latin America and Africa.) The report highlights how the disparities that exist between Northern and Southern countries, in terms of science and knowledge, will become a greater hindrance to the development and practice of effective climate change reduction actions and policies. The researchers explore the extent of this particular North-South divide, study the underlying issues associated with it, and examine the potential consequences for climate change policy development and implementation.

Depletion of Fossil Fuels and Climate Change

by Makari Krause

Fossil fuels, while a large part of our energy production, are not a renewable resource and will eventually be depleted. Current climate models, such as the ones used by the IPCC, use levels of future fossil fuel production that Hook and Tang (2013) think are improbable. While fossil fuel combustion currently causes a large part of anthropogenic greenhouse gas emissions, these emissions are linked to fossil fuel production and will decrease as we begin to run out of these resources. There is a multitude of different scenarios that predict future fossil fuel emission and they range hugely in their predictions. The IPCC uses a set of six scenarios called the Special Report of Emission Scenarios (SRES), which are an input for many of their aggregated climate models and influence their conclusions. Hook and Tang question the accuracy of these SRES and aim to review the assumptions that the scenarios make about fossil fuel availability. Continue reading
