How scientists calculate climate change
Vilhelm Bjerknes, Oliver Morton
Building on Wilhelm Bjerknes' 19th-century formulas, modern atmospheric computers now operate 25 trillion times faster than early models to simulate global climate behavior through complex grid systems. Although technical limitations regarding small-scale cloud dynamics create divergent warming projections, historical data confirms these tools accurately forecast observed trends when paired with economic scenarios that link human policy to temperature outcomes. Ultimately, while these models cannot predict human decisions, they remain the essential instrument for quantifying carbon dioxide's impact and guiding the stringent emission reductions necessary to meet Paris Agreement targets.

Why politicians have failed to tackle climate change
Following James Hansen's 1988 congressional testimony, global climate diplomacy progressed through the binding yet flawed 1997 Kyoto Protocol to the 2015 Paris Agreement, which replaced mandatory targets with voluntary commitments. While fossil fuel interests historically obstructed regulation and developing nations like China initially grew emissions unchecked, strategic shifts now drive a transition toward renewable leadership despite emissions doubling since the 1970s. Current international strategy relies on a ratcheting mechanism to incrementally raise ambition, though avoiding effective inaction requires breaking a half-century of political compromise to meet temperature thresholds.

Who owns the Moon?
Dennis Hope, Vicky Jeong, Oliver Morton, Anna
Driven by geopolitical rivalry and plummeting launch costs, the international community is preparing for a surge of lunar missions targeting the South Pole to secure water and strategic minerals. While the 1967 Outer Space Treaty prohibits national ownership of the Moon, it leaves the legal status of resource extraction ambiguous, creating a landscape where nations like the US favor "finders keepers" principles over existing international precedents. This legal uncertainty and the potential for disputes mirroring terrestrial conflicts will likely persist until commercial operations, such as mining or tourism, become physically established on the surface.
