  • O Say Can You CO2?
    Guest Commentary by Scott Denning The Orbiting Carbon Observatory (OCO-2) was launched in 2014 to make fine-scale measurements of the total column concentration of CO2 in the atmosphere. As luck would have it, the initial couple of years of data from OCO-2 documented a period with the fastest rate of CO2 increase ever measured, more […]

  • 1.5ºC: Geophysically impossible or not?
    Guest commentary by Ben Sanderson Millar et al?s recent paper in Nature Geoscience has provoked a lot of lively discussion, with the authors of the original paper releasing a statement to clarify that their paper did not suggest that ?action to reduce greenhouse gas emissions is no longer urgent?, rather that 1.5ºC (above the pre-industrial) […]

  • ?the Harde they fall.
    Back in February we highlighted an obviously wrong paper by Harde which purported to scrutinize the carbon cycle. Well, thanks to a crowd sourced effort which we helped instigate, a comprehensive scrutiny of those claims has just been . Lead by Peter Köhler, this included scientists from multiple disciplines working together to clearly report on […]

  • Unforced variations: Oct 2017
    This month’s open thread. Carbon budgets, Arctic sea ice minimum, methane emissions, hurricanes, volcanic impacts on climate… Please try and stick to these or similar topics.

  • Is there really still a chance for staying below 1.5 °C global warming?
    There has been a bit of excitement and confusion this week about a new paper in Nature Geoscience, claiming that we can still limit global warming to below 1.5 °C above preindustrial temperatures, whilst emitting another ~800 Gigatons of carbon dioxide. That?s much more than previously thought, so how come? And while that sounds like […]
