Not “may” as the natural cycles are turning down with respect to atmospheric temperature.
As with the annual seasons, the longer cycles of natural warming and cooling lag the causal factors.
The Solar activity peaked around the turn of the century. Using an annual cycle in the Northern Hemisphere as an analogy, we are in September or October. That’s an annual equivalent to 3 months after the peak of energy from the sun. Cold spells become apparent. But, winter officially starts on the first day in December.
If the atmospheric temperature measurements are not continually ‘adjusted’ up, we should see the clear downward trend over the next few years.
I wish it were not true, cold is the killer, both directly and indirectly with loss of food crop yields.
