To stabilize climate change, we need to get to zero net carbon emissions by the end of the century. A key question then for policymakers is when and how to reduce emissions. Imagine you are a policymaker, and you have two options for reducing emissions. Energy efficiency measures in the building sector (LED lights instead of light bulbs, better thermal insulation) can reduce … [Read more...] about Climate Policy: When the Expensive Options Make Sense
The last few months have been big ones for conservation in Latin America. New and expanded national parks covering millions of hectares have been created, encompassing everything from the towering tepuis and ancient rock art of Colombia's Amazon to the lowland rivers of the Peruvian Amazon and the temperate rain forests of Chile's Patagonia. It couldn't come soon enough. … [Read more...] about New National Parks Can Help Latin America Tackle its Drought Problem
When researchers consider the economic costs of climate change, they often estimate models based on historical temperature and economic data. But it can be difficult to account for adaptation. Typically, these models estimate an upper bound of the economic costs of climate change. Future adaptation, it is assumed, will reduce those costs. But adaptation could play a more … [Read more...] about Can Small Farmers Adapt to Climate Change Shocks?
The word out of Bonn, where the latest United Nations Climate summit came to an end Nov. 18, is hardly encouraging. Assuming that countries honor their commitments to reduce greenhouse gas emissions made to date, the globe's temperature will still rise at least 3 degrees Celsius (5.4 degrees Fahrenheit) this century, 1 degree Celsius above the agreement established at the Paris … [Read more...] about Stepping Up the Struggle Against Climate Change
Mexico was the world's first developing nation to commit. The rest of Latin America and the Caribbean followed. Taking stock of climate change’s effects on sea rise, extreme weather, crop failures and disease, the region united at the 2015 United Nations climate summit in Paris to pledge to reduce greenhouse gas emissions and lay out paths for doing so. Now, governments face … [Read more...] about Modeling Tradeoffs in the Fight Against Climate Change
