Current emissions of anthropogenic greenhouse gases (GHGs) have already committed the planet to an increase in average surface temperature by the end of the century that may be above the critical threshold for tipping elements of the climate system into abrupt change with potentially irreversible and unmanageable consequences. This would mean that the climate system is close to entering if not already within the zone of “dangerous anthropogenic interference” (DAI). Scientific and policy… Expand
Coping with Climate Change in the Next Half-Century
GREENHOUSE GAS (GHG) concentrations are trending far * off the path needed to avoid dangerous interference in the cli- mate system, and nations are making little progress in the di- plomacy to cutExpand
Well below 2 °C: Mitigation strategies for avoiding dangerous to catastrophic climate changes
TLDR
This work outlines a three-lever strategy to limit the central warming below the dangerous level and the LPHI below the catastrophic level, both in the near term (<2050) and in the long term (2100): the carbon neutral lever to achieve zero net emissions of CO2, the super pollutant lever to mitigate short-lived climate pollutants, and the carbon extraction and sequestration lever to thin the atmospheric CO2 blanket.

What Role for Short-Lived Climate Pollutants in Mitigation Policy?
TLDR
An emerging strategy, which is referred to as hybrid climate mitigation (HCM), emphasizes reducing SLCPs in parallel with long-lived carbon dioxide (CO2) so as to achieve climate goals, as well as health and food security benefits, associated with some of the S LCPs. Expand

TLDR
Even the most aggressive CO2 mitigation steps as envisioned now can only limit further additions to the committed warming, but not reduce the already committed GHGs warming of 2.4°C. Expand

TLDR
A comprehensive probabilistic analysis aimed at quantifying GHG emission budgets for the 2000–50 period that would limit warming throughout the twenty-first century to below 2 °C, based on a combination of published distributions of climate system properties and observational constraints is provided.

Irreversible climate change due to carbon dioxide emissions
TLDR
The climate change that takes place due to increases in carbon dioxide concentration is largely irreversible for 1,000 years after emissions stop, showing that thermal expansion of the warming ocean provides a conservative lower limit to irreversible global average sea level rise. Expand
The importance of the Montreal Protocol in protecting climate
TLDR
Using historical ODSs emissions and scenarios of potential emissions, it is shown that the ODS contribution to radiative forcing most likely would have been much larger if the O DS link to stratospheric ozone depletion had not been recognized in 1974 and followed by a series of regulations. Expand
