Areas of Latin America, like Mexico and Chile, have some of the world's greatest solar potential. But a new technological development in solar cells could allow them to harness more of the sun's energy and speed the growth of solar in the region. The new solar cells are known as perovskites. They are made of a crystalline structure and can be printed on sheets of plastic or … [Read more...] about Pushing the Frontier of Solar Cells
Environment and Climate Change
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
The lashing rains and 185-mile-per-hour winds pounding the Caribbean from Hurricane Irma; the toppled homes and flooded streets in Texas and Louisiana from Hurricane Harvey, with its tens of thousands of people made homeless and billions of dollars in property losses: it's hard to imagine things getting much worse. Unfortunately, they almost surely will. If scientists agree … [Read more...] about Bracing for Impact: Preparing Nations for Natural Disasters
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
