On a simplified solution of climate-carbon dynamics in idealized flat10MIP simulations Open
Idealized experiments with coupled climate-carbon Earth system models (ESMs) provide a basis for understanding the response of the carbon cycle to external forcing and for quantifying climate-carbon feedbacks. Here, we analyze globally-ave…

The carbon and climate impacts of forestation in Australia Open
Forestation is a feasible and cost-effective strategy to remove CO2 from the atmosphere and store it in natural reservoirs. However, it is highly uncertain how much carbon new forests can remove, how those changes will affect the climate a…

ESD Ideas: Extended net zero simulations are critical for informed decision making Open
Climate changes under net zero emissions will take many centuries to play out, particularly in the Southern Hemisphere and in the ocean and cryosphere. New millennial-length Earth System Model simulations are required to better understand …

Heatwaves in a net zero World Open
While historical and future increases in heatwave frequency, duration and intensity are well documented, no studies have yet examined heatwave changes after anthropogenic greenhouse gas emissions reach net zero. We address this by examinin…

The Sequestration Efficiency of the Deep Ocean Open
The abyssal ocean may provide adequate sequestration for Carbon Capture and Storage and Carbon Dioxide Removal. The transit of carbon from seafloor release to ocean surface can take millennia, as it occurs through many water pathways chara…

flat10MIP: an emissions-driven experiment to diagnose the climate response to positive, zero and negative CO <sub>2</sub> emissions Open
The proportionality between global mean temperature and cumulative emissions of CO2 predicted in Earth system models (ESMs) is the foundation of carbon budgeting frameworks. Deviations from this behavior could impact estimates of required …

Revised estimates of temperature changes under net zero CO2 emissions Open
It is critical that climate changes beyond net zero are well understood to inform policymaking. Here we present a new estimate of post-abrupt net zero CO2 temperature changes using a method that filters for variability on multiple timescal…

Enhancing communication of climate changes under net zero emissions Open
Much of the public discourse around climate changes under net zero carbon dioxide emissions has been focused on global mean temperature changes after emissions cessation, which are expected to be limited. More attention needs to be paid to…

Simulated ocean oxygenation during the interglacials MIS 5e and MIS 9e Open
Recent studies investigating future warming scenarios have shown that the ocean oxygen content will continue to decrease over the coming century due to ocean warming and changes in oceanic circulation. However, significant uncertainties re…

Biogeochemical versus biogeophysical temperature effects of historical land-use change in CMIP6 Open
Anthropogenic land-use change (LUC) substantially impacts climate dynamics, primarily through modifications in the surface biogeophysical (BGP) and biogeochemical (BGC) fluxes, which alter the exchange of energy, water, and carbon with the…

European heat extremes under net-zero emissions Open
Projections of European heat extremes have been widely explored in the context of continued global warming. However, analyses of recent Earth system model simulations point to substantial climatic changes over multi-centennial timescales i…

Evolution of Heat Extremes Under Net‐Zero CO<sub>2</sub> Emissions Open
Anthropogenic emissions of greenhouse gases have warmed the planet by around 1.3°C and have contributed to the intensification of heat extremes. To stop continued global warming, we understand that we must reach and sustain net‐zero global…
