    Opinion – Climate change is usually discussed in terms of rising temperatures.
    But scientists often use a different measure, known as “equilibrium climate sensitivity”. This is defined as the global mean warming caused by a doubling of pre-industrial carbon dioxide (CO₂) levels in the atmosphere.
    We use this measure to describe the range of potential temperature increases on longer timescales, and to compare how well climate models reproduce observed warming….

    Measuring long-term climate sensitivity is central to future predictions, but we are already seeing the effects of warming across the world with extremes in weather, even at the low end of the range. We argue efforts to boil down Earth’s response to climate change to one number may be unhelpful…

    About a century before the first computational estimates of Earth’s climate sensitivity were published in 1967, the Swedish physicist and 1903 Nobel laureate Svante August Arrhenius was the first to estimate values at 4-6°C.

    Since the early efforts to model Earth systems, computer simulations have steadily increased in complexity. The first models only simulated the atmosphere, but they have evolved to include vegetation, processes in the ocean and sea ice.
    While undoubtedly beneficial to the understanding of fundamental science, each of these added processes has introduced uncertainties in the models’ warming response…
