Continuing business-as-usual with regards to greenhouse-gas emissions will increase the likelihood of 'dangerous' climate changes. In response to this risk, Crutzen1 argued in 2006 that a 5 °C warmer world will probably have catastrophic consequences and that the only way out may be to engineer the Earth's climate by injecting aerosols into the stratosphere. The possibility of a future 'climate emergency' has subsequently been used to justify research on climate engineering2 — the deliberate modification of the Earth's climate. Over time, the emergency framing has evolved to become a central argument for why we should consider investigating solar radiation management (SRM) techniques, which reduce the amount of sunlight absorbed at the Earth's surface. But whether SRM can possibly prevent or counteract a climate emergency raises the more fundamental question of what a climate emergency actually is.
