Europe's recent summers were the 'warmest in 2,000 years'

I notice Google Chrome doesn't put a line break between copied paragraphs. I usually use FireFox, which does, but I'm going to be working on Tax-Aide certification, which doesn't work right on FireFox.

The past 30 years in Europe have likely been the warmest in more than two millennia, according to new research.
The study used tree ring records and historical documents to reconstruct yearly temperatures going back 2,100 years.
Scientists say that past natural variability in temperatures was greater than previously thought.
As a result, climate models may be underestimating the frequency and severity of heat waves in the future.
According to the study, Europe has seen an increase in summer warming of 1.3C [2.3F] between 1986 and 2015.
In this period there has also been an increase in severe heat waves, most notably in 2003, 2010 and 2015.
The 2003 event was linked to the extra deaths of thousands of elderly people due to heat stroke, dehydration and increased air pollution.


"We've got 2,000 years of reconstruction where we have values for every year and the big surprise was that there wasn't a single 30-year period that was as warm as the last 30 years; that was unexpected," said Prof Danny McCarroll from Swansea University, UK, who was part of the research group.


Even though the new reconstruction has a wider range of natural variability in summer temperatures than previous attempts, the temperature data recorded in the past 30 years still sits outside it, pointing towards the same inference as made by the IPCC - that the recent warming is mainly caused by humans.
