Solar power has a major role to play in cutting carbon emissions, but producing photovoltaic cells from silicon – the long-time market leader – is an energy-intensive process. Cells made from perovskites offer a promising alternative, and recent advances have pushed their efficiencies beyond 25.5%, just shy of silicon’s record.

Lo first became interested in this area while studying physics and astronomy at Durham University , UK, where her final-year project looked at how to calibrate telescopes to correct for atmospheric effects on the radiation they detect. Eunice Lo is a researcher at the University of Bristol and frequently contributes to climate reports.

This is because of black carbon’s enhanced ability to absorb visible light; it actually absorbs nearly a million times more energy per unit mass than CO 2. Black carbon’s lifetime is on the order of days to a couple weeks, which is about 0.004% of the lifetime of other pollutants like CO 2 (which has a lifetime of 300 – 1000 years).

What’s harder is knowing the carbon footprint of building materials throughout their lifecycle, which requires reams of data about supply chains and logistics that either don’t exist or have never been tracked. Overall, cement accounts for 3% of the world’s carbon emissions. Wood you believe?

We are at a game-changing moment for all of humanity, as climate science tells us exactly where we’re headed if we don’t reduce carbon emissions urgently. However, with the right policy changes and a commitment to diplomacy, the United States can be a leader in reducing the nuclear threat.
