It has been suggested here that cold extremes lead to more mortality than heat. I refer you to new published research on the subject http://www.sciencedaily.com/releases/2015/05/150520193831.htm
That source also had a link to: http://www.sciencedaily.com/releases/2012/09/120918184816.htm Their thinking is: Risk of premature CVD death rose more when extreme heat was sustained for two or more days, researchers found. "This might be because people become exhausted due to the sustained strain on their cardiovascular systems without relief, or health systems become overstretched and ambulances take longer to reach emergency cases," said Adrian G. Barnett, Ph.D., co-author of the study and associate professor of biostatistics at QUT. "We suspect that people take better protective actions during prolonged cold weather, which might be why we did not find as great a risk of CVD during cold spells." Bob Wilson
Yes, here we might look at only the thermal side. Cardio pulmonary consequences for urban air pollution (PM2.5, ozone, oxides of nitrogen) are handled extensively elsewhere.
wasn't this a big deal a few years back, when the french went on holiday, leaving their parents at home to die in an extreme heat wave?
Not just the French. But it makes sense that heat deaths are rare and would show up in the press. Meanwhile the cold related death barely raise an eyebrow. Bob Wilson
According to this new research, cold-weather deaths would not decline much with anticipated degree of warming. http://www.sciencedaily.com/releases/2015/06/150619084609.htm
After they killed the witches, it became warmer. Little Ice Age, Big Consequences — History in the Headlines "Great Famine Beginning in the spring of 1315, cold weather and torrential rains decimated crops and livestock across Europe. Class warfare and political strife destabilized formerly prosperous countries as millions of people starved, setting the stage for the crises of the Late Middle Ages. According to reports, some desperate Europeans resorted to cannibalism during the so-called Great Famine, which persisted until the early 1320s. Black Death Typically considered an outbreak of the bubonic plague, which is transmitted by rats and fleas, the Black Death wreaked havoc on Europe, North Africa and Central Asia in the mid-14th century. It killed an estimated 75 million people, including 30 to 60 percent of Europe’s population. Some experts have tied the outbreak to the food shortages of the Little Ice Age, which purportedly weakened human immune systems while allowing rats to flourish."
I was very glad to read that history.com story from 2012 It includes this quote: "According to the latest study, described by an international team in this week’s Geophysical Research Letters, volcanic eruptions just before the year 1300 triggered the expansion of Arctic sea ice, setting off a chain reaction that lowered temperatures worldwide. Find out about some of the numerous trends and events climatologists and historians have chalked up to the Little Ice Age—either rightly or wrongly—over the years." It refers to this article: Abrupt onset of the Little Ice Age triggered by volcanism and sustained by sea-ice/ocean feedbacks - Miller - 2012 - Geophysical Research Letters - Wiley Online Library It may be surprising that mojo is drawing our attention towards possible causes of LIA other than absence of 3 (4?) solar cycles.But it's probably good for us to keep an open mind about it.
and yet humanity survived the Ice Age. I doubt those folk had much luck putting their camp fires inside igloos To have food, you have to have water. Not much of that water thing going on in the middle of the hot Sahara, or Mojave Desert. On the other hand you hardly ever see a skinny Eskimo. This, coming from a fella that just sold their 2nd home maybe 45 minutes south of Glacier National Park. Lots of big / edible critters in cold regions. And whether man made or not, the cold regions are quickly withering away. .
People migrated or died. or migrated and died. Or coped you know wih that fire in side ice You often have to have a fire to drink safe water. Not quite sure where you are going here. If we are talking fat, I think samoans not inuit. If I'm thinking really fat humans, I'm thinking that Carl Thompson that died yesterday at 33 and around 910 pounds. What makes no sense to me is this guy was on welfare, but they kept bringing him food. Carl Thompson, Britain's fattest man, inundated with offers of weight loss help | Daily Mail Online But yes you need water. Now that we have airconditioning and guns people are able to live easily in hotter places ;-), and desert people with money can import food and desalinate water. It takes a lot of land to feed a human in a cold place. Since there is oil and prisons in cold places more people have moved there.
I'd rather deal with the cold than heat (which is probably why I live in Minnesnowta). I can always put more layers on.
Stimulated by #12, I found two published articles that found weak connections between solar cycles and these geophysical events. So what we have so far are highly variable process rates, with a small part of that variability coincident with solar cycles. It does not quite rise to the level of 'solar cycles cause...' because that implicitly excludes other causes. Other, more adventurous minds might take it a bit further. We have a better chance of further exploring this with volcanic, than earthquake history. The long ice cores have annually resolvable sulfate deposition. Old earthquakes can (and have been) 'dated' but with much less than 11-year resolution.
15,000 died in France in 2003 due to the August heat wave. Many of the deaths were older and single people living in the lower rent apartments at the top of many very old Paris buildings. (Paris being an old city.) These apartments were formerly servants quarters with very limited ventilation. There the heat accumulated at the top apartments and turned a great many of these places into infernos.
