To prevent worsening and potentially irreversible effects of climate change, the world’s average temperature should not exceed that of preindustrial times by more than 1.5 degrees Celsius. But why 1.5 degrees C and how close are we to achieving this goal?

Methane is the second most impactful human-generated greenhouse gas after carbon dioxide. Desirée Plata, an environmental engineer and professor at MIT, is developing tools to reduce methane with the goal of cutting emissions by 45% by 2030, which would save up to 0.5 degree Celsius of warming by 2100.

Cities around the world have been adopting policies and incentive programs to encourage building retrofits to reduce their energy use and carbon emissions. But analyses from an MIT team have revealed that cities’ retrofit plans often won’t achieve their goals—although decarbonizing the local grid could make the difference.
