Two decades ago, the so-called “Hockey Stick” curve , published in 1999 by me and my co-authors (Mann, Bradley and Hughes, 1999) , was featured in the all-important “Summary for Policy Makers” (SPM) of the 2001 IPCC Third Assessment report. The relevant statements in the SPM and Technical Summary are: A.2.2

For instance in Tokyo and Seoul, the first hot day of the year (30°C or higher) arrived on average 11 days earlier during the period 2001-2020 compared to the previous two decades. Between 2001 and 2020, the frequency of heatwaves in Beijing was nearly three times that of the previous 40-year period. in the morning. .

For context, 10 out of 17 models in CMIP2 (~1995) used flux adjustments, and 6 out of 24 in the CMIP3 ensemble (~2001), but none in CMIP5 or CMIP6, while each generation has greater skill than the previous one. As you will recall, Hansen had declared in 1988 that “the greenhouse effect is here!”, Gnanadesikan et al.,

These nature-based solutions actively contribute to mitigating greenhouse gas emissions and harnessing the immense potential of forests as carbon sinks. On the other hand, soil carbon capture methods involve conservation agriculture techniques such as reduced tillage, cover cropping, and agroforestry (Robert, 2001). Mulligan, J.,

Many see this cutting edge enactment as crucial to making possible the State’s ESG goal of reducing greenhouse gas emissions in buildings. In 2001, Maryland was one of the first states to incentivize green building, to reduce GHG emissions, with an income tax credit. The backstory is important.

The CERES estimates of the top-of-atmosphere radiative fluxes are available from 2001 to the present. We can explore the issues and pitfalls of this using the ‘simple model’ of the greenhouse effect we explored back in 2007. The simplest model for the greenhouse effect. A simple model with feedbacks.

One formulation that has been suggested is, “What are the obligations under international law of a State for ensuring that activities under its jurisdiction or control that emit greenhouse gases do not cause, or substantially contribute to, serious damage to another State or State?” Once the opinion is issued, what impact would it have?
