How America is racing China to the Moon | The Economist
The Artemis II crew successfully launched on NASA's largest rocket, marking the first human spaceflight beyond Low Earth Orbit since the Apollo era. Under Administrator Jared Isaacman's leadership, this reconnaissance mission accelerates U.S. lunar ambitions to counter China's 2030 landing plans and establish a permanent lunar presence rather than a temporary visit. The spacecraft is currently executing a unique trajectory designed to culminate in a splashdown near San Diego by mission day ten, paving the way for the eventual Artemis III lunar landing.

Heatwaves: how hot can it get?
Global heat extremes driven by a 1°C rise in atmospheric temperatures are causing record-breaking mortality rates in South Asia, Europe, and the United States, with specific meteorological patterns like heat domes and jet stream blocking intensifying these events. Critical survival thresholds are being approached as wet bulb temperatures near lethal limits in vulnerable regions, while secondary factors such as sleep disruption and pre-existing health conditions accelerate heat-related fatalities. To mitigate these escalating risks, successful adaptation strategies modeled after France's post-2003 welfare interventions must be implemented alongside public education and urban policy shifts in areas lacking historical heat precedents.

What causes hurricanes?
Hurricanes are classified tropical storm systems defined by sustained winds of at least 74 mph that form over warm oceans when specific atmospheric and thermal conditions converge. These massive energy engines generate winds exceeding 200 mph and release rainfall at rates capable of causing billions in damages, with water-driven phenomena like storm surges accounting for the vast majority of fatalities. While climate change may not increase the total number of storms, warming oceans and rising sea levels are intensifying rainfall and slowing storm movement, necessitating a strategic shift toward infrastructure adaptation rather than intensity reduction.

Green building: can mushrooms help?
Addressing the construction sector's contribution of 11% to global CO2 emissions, experts are evaluating alternatives to carbon-intensive concrete such as sustainably sourced wood and emerging materials like mycelium. While renewable energy-powered aluminum and flexible architectural designs offer promising pathways for decarbonization, significant barriers remain, including wood price volatility and the structural limitations of biological composites in terrestrial environments. Consequently, achieving global sustainability goals requires distinct strategies for developed nations versus emerging economies, where the informal nature of the industry necessitates government intervention in high-density housing to effectively reduce per-capita greenhouse gas output.

Who should fix climate change?
Sasha Nauta, Katrine Braik, Oliver Morton
The discussion establishes that democratic governments must lead climate action through policy intervention, citing Germany's solar subsidies as proof that state support is essential for market transformation where laissez-faire approaches fail. Corporate leaders are expected to integrate climate strategies into core business models rather than relying on individual goodwill, a shift exemplified by Tesla's high-margin entry strategy and Microsoft's commitment to offsetting its entire historical carbon footprint. By coupling sharp emissions reductions with economic growth, the event argues that prioritizing long-term systemic protection for vulnerable populations is the only viable path to a sustainable future.

Nuclear power: why is it so unpopular?
Although nuclear energy currently supplies 10% of global electricity as a reliable low-carbon alternative, its growth is stifled by high construction costs, severe public fear stemming from accidents like Chernobyl and Fukushima, and complex geopolitical proliferation risks. While statistical data suggests nuclear power is among the safest energy sources per unit of electricity, the industry faces a stagnation in reactor numbers and a lack of a projected "nuclear renaissance" due to competition from falling renewable costs. Consequently, the future of the sector hinges on whether advanced modular technologies can resolve long-standing issues with standardization and economic viability against established alternatives.

The carbon cycle is key to understanding climate change
Human fossil fuel combustion has disrupted Earth's natural carbon equilibrium, accelerating the transition into the Anthropocene and trapping heat at unprecedented rates. While the "Growing Green" movement reflects public demand for reduction, current political and technological limitations, particularly regarding the scalability of negative emission schemes, prevent a rapid restoration of pre-industrial conditions. Ultimately, reversing this geological shift demands a fundamental transformation of the global economic structure, a process that will span centuries regardless of whether the transition is driven by policy or necessity.

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.
