You really can’t go home again: An update of “Getting back to 350 ppm CO2 …”

I have made an important update to an earlier post here, Getting back to 350 ppm CO2: You can’t go home again. The message, essentially based upon recent work Tokarska and Zickfield on one hand, and by The Global Carbon … Continue reading

Getting back to 350 ppm CO2: You can’t go home again

(Major update of this piece included below.) You can’t. It’ll cost much more than 23 times 40 times the Gross World Product to do it. And, in any case, you need to go to where you need to be to … Continue reading

That two degree limit is closer than it appears

The UNFCCC’s COP21 concluded goals which aimed for limiting global warming to C, and certainly keeping it below C, both measured with respect to pre-industrial temperatures. Bad news. According to the United States National Center for Atmospheric Research (“NCAR”), in … Continue reading

Paris’ COP21: Great cheerleading from the diplomats, but … +ENSO is here

This target is, however, extremely demanding. Climate researchers have explored only a few scenarios that limit warming to 1.5 °C. They show that global emissions of greenhouse gases must be between 70% and 95% lower in 2050 than they were in … Continue reading
