Global warming will not reduce deaths in the winter months, British study concludes

New information released today finds that global warming is not likely to lessen britain's excess winter dying rate as formerly thought. The research is released within the journal Character Global Warming and debunks the broadly held view that warmer winters will cut the amount of deaths normally seen in the very coldest season.

Examining data in the past six decades, scientists in the College of Exeter and College College London (UCL) checked out the way the winter dying rate has transformed with time, and just what factors affected it.

They discovered that from 1951 to 1971, the amount of cold winter days was strongly associated with dying rates, while from 1971 to 1991, both the amount of cold days and flu activity were accountable for elevated dying rates. However, their analysis demonstrated that from 1991 to 2011, flu activity alone was the primary cause in year upon year variation in the winter months mortality.

Lead investigator Dr Philip Staddon stated "We have proven that the amount of cold days inside a winter no more describes its quantity of excess deaths. Rather, the primary reason for year upon year variation in the winter months mortality in recent decades continues to be flu."

They claim that this reduced outcomes of the amount of cold days and deaths inside a winter could be described by enhancements in housing, healthcare, earnings along with a greater understanding of the potential risks from the cold.

As global warming progresses, the United kingdom will probably experience growing weather extremes, including more less foreseeable periods of utmost cold. The study highlights that, despite a generally warmer winter, a far more volatile climate could really result in elevated amounts of winter deaths connected with global warming, instead of less.

Dr Staddon thinks the findings have important implications for policy:

"Both policy makers and health care professionals have, for a while, assumed that the potential take advantage of global warming is a decrease in deaths seen over winter. We have proven this is not likely to be. Efforts to combat winter mortality because of cold spells shouldn't be lessened, and individuals against flu and flu-like ailments ought to be maintained."

Co-author, Prof Hugh Montgomery of UCL stated:

"Global warming seems unlikely to reduce winter dying rates. Indeed, it might substantially increase them by driving extreme weather occasions and greater variation in the winter months temps. Action must automatically get to prevent this happening."

Co-author, Prof Michael Depledge of College of Exeter School Of Medicine stated:

"Studies from the kind we've carried out provide information that's key for policymakers and political figures planning to handle the impacts of global warming. We are hopeful that the significance of this problem is going to be understood, to ensure that matters of health insurance and environment security could be worked with seriously and effectively."
