A globally warm medieval period could be a simple forced response to increased solar, in which case it doesn't imply any larger intrinsic variability than already assumed, and since solar has been pretty much constant over the last 50 years, improvements to our understanding of solar forced climate changes are irrelevant for the last few decades.

Starting from an old equilbrium, a change in radiative forcing results in a radiative imbalance, which results in energy accumulation or depletion, which causes a temperature response that approahes equilibrium when the remaining imbalance approaches zero — thus the equilibrium climatic response, in the global - time average (for a time period long enough to characterize the climatic state, including externally imposed cycles (day, year) and internal variability), causes an opposite change in radiative fluxes (via Planck function)(plus convective fluxes, etc, where they occur) equal in magnitude to the sum of the (externally) imposed forcing plus any «forcings» caused by non-Planck feedbacks (in particular, climate - dependent changes in optical properties, + etc.).)

The uncertainties in the historical tropical cyclone records, the incomplete understanding of the physical mechanisms linking tropical cyclone metrics to climate change, and the degree of tropical cyclone variability provide only low confidence for the attribution of any detectable changes in tropical cyclone activity to anthropogenic influences.

The disagreement arises from different assessments of the value and importance of particular classes of evidence as well as disagreement about the appropriate logical framework for linking and assessing the evidence — my reasoning is weighted heavily in favor of observational evidence and understanding of natural internal variability of the climate system, whereas the IPCC's reasoning is weighted heavily in favor of climate model simulations and external forcing of climate change.

In principle, changes in climate on a wide range of timescales can also arise from variations within the climate system due to, for example, interactions between the oceans and the atmosphere; in this document, this is referred to as «internal climate variability».

We can not rule out the possibility that some of the low - frequency Pacific variability was a forced response to variable solar intensity and changing teleconnections to higher latitudes that are not simulated by the models, or that non-climatic processes have influenced the proxies... the paleodata - model mismatch supports the possibility that unforced, low - frequency internal climate variability (that is difficult for models to simulate) was responsible for at least some of the global temperature change of the past millennium.»
