The exploration of ocean worlds in the outer Solar System offers the opportunity to search for an independent origin of life, and also to advance our capabilities for exploring and understanding life in Earth’s oceans.
Making sense of exoplanet observations requires better understanding of terrestrial atmospheres in our solar system, especially for Venus. We need to not just intermittently explore, but continuously monitor these atmospheres — like we do for Earth.
Temperature overshoot scenarios that make the 1.5 °C climate target feasible could turn into sources of political flexibility. Climate scientists must provide clear constraints on overshoot magnitude, duration and timing, to ensure accountability.
