Urbanization and human-caused climate changes have led to increases in heat events around the world. For example, in July 2012, an extreme heat wave hit the Chicago area, causing temperatures to skyrocket to 40°C (104°F) and above. Chicago, like most cities, is affected by urban heat islands (UHIs), which occur when changes in land cover create spaces that are warmer than their surrounding area. Satellite measurements can be used to inform models to characterize the intensity of UHIs, yet satellite techniques have some limitations—expensive sensors and low temporal resolution, among other drawbacks. But quantifying the intensity of UHIs could help public health officials and city planners learn to mitigate the impacts of future heat waves.

Research On the Line
The renewable energy sector is booming, and as demand for clean energy rises, so too does demand for the metals it relies on—copper and nickel chief among them. As the world continues scaling up renewables to meet the goals of the Paris Agreement, demand will almost certainly top supply in the coming decades. To address this future gap, an international group of researchers and the mining giant BHP teamed up to identify the processes that determine whether or not these metals make it into accessible deposits in the crust.
