RT by @parholmgren: How We Know that Global Warming is Accelerating and that the Goal of the Paris Agreement is Dead

Summarized here:

The drive for global temperature change is Earth’s energy imbalance (EEI), the difference between the energy Earth receives from the Sun and energy Earth reflects and radiates back to space. We have good measurement of EEI today based on precise satellite data for change of reflected and emitted radiation calibrated by decadal ocean heat content change measured by deep-diving Argo floats. Interpretation of global temperature change and prediction of future temperature requires knowledge of the principal forcings that now affect EEI: human-made greenhouse gases (GHGs) and atmospheric aerosols (fine airborne particles). Aerosol climate forcing is not being measured, but information on aerosol forcing can be extracted from an ongoing “great inadvertent aerosol experiment” as a result of discrete changes in International Maritime Organization (IMO) regulations on the sulfur content of ship fuels. These limited assessment tools are threatened by the absence of firm plans to continue direct EEI observations. A shortcoming of our climate science is failure to communicate well what is known from existing data. Global warming in the pipeline and emissions in the pipeline assure that the goal of the Paris Agreement – to keep global warming well below 2°C – is already dead, if policy is constrained only to emission reductions plus uncertain and unproven CO2 removal methods.
