heat wave

It really is true that global warming has made heat waves more common and more severe. The heat wave last month that affected the American southwest was one of these. Yet, of the 433 local broadcast events in local TV affiliates in Phoenix and Las Vegas to mention the heatwave (which was current news at the time) only one event mentioned a climate change connection, and that was to downplay it. Similarly, governments are ignoring the connection. This is the people who are supposed to help or at least disseminate correct information, letting everyone down for, I assume, political reasons.…
Humans have been releasing greenhouse gas pollution into the atmosphere for a long time now, and this has heated up the surface of the planet. This, in turn, has caused a number of alarming changes in weather. Several current weather events exemplify the effects of climate change. Record High Temperatures Being Shattered South Asia recently experienced a number of killer heatwaves, and that is still going on in the region. More recently, we've seen long standing record highs being broken in the American West. The Capital Climate group recently tweeted this list of records: Hot Whopper…
Some remarkable weather in North America recently as most of you probably know.  Check out Jeff Masters for some of the details. Record warmth and precipitation in AlaskaAs of January 26, 13.83" of precipitation had fallen in Valdez during the month of January. This is more than 8" above average for this point in the month, and close to the all-time record for January precipitation of 15.18", set in 2001 (records go back to 1972.) With more rain on the way Monday and Tuesday, this record could easily fall. Numerous locations in Southeast Alaska have beaten their rainiest January day on record…
So, how has the Atlantic hurricane season shaping up so far? According to data accumulated by the National Weather Service, as shown (with added items) here ... ... we should have had about four or five named storms at this point in the season. Since numbers for this time of year are small, variation is large, so this is not too meaningful but it can give us an idea. So far, we have had these storms in the Atlantic: Tropical Storm ANDREA Tropical Storm BARRY Tropical Storm CHANTAL Tropical Storm DORIAN Tropical Storm ERIN The next storm will be named Fernand, and it may be forming as we…
So Tasmania is in the news, which is where I am living (see here for links).  The stories are about heat and bush fires.  So far, nothing as dramatic as "Black Saturday" four years ago has happened, thank goodness, but conditions are very similar. The post's "featured image" above is of the electronic weather station monitor sitting in my kitchen, taken last Friday.  The official Hobart record was set at 41.8 oC, we had a reading of 43.3 oC (33.5 was the inside temperature).  I have no idea if this device is well calibrated or subject to some particular siting problem (I tried) or if it…
As most of the country slowly roasts in one of the worst heat waves so far, I thought it was worth reminding people that one can stay safe in the heat, even without air conditioning. This is important now for the millions of people who don't own air conditioners, who don't want the environmental impact of an air conditioner, or who find themselves for various reasons, without power in the hot weather. As we all know, this is peak season for brown and blackouts. There are a lot of parallels between dealing with extreme heat and extreme cold in a difficult situation. The first and most…
Today, I took out the trash. I may or may not have taken the trash out last week, but I can tell you that the last time I did take it out, whenever it was, I had to drag the trash barrel across ice. Yesterday I went to the gym without a coat or jacket. That made me have to decide if I wanted to go to the locker room to stow the contents of my pockets (car keys, etc.) or just keep those things in my pocket. The grass outside is green. We expect snow on Friday. Where I grew up, in what is now known among gardeners and cooperative extension agents as Zone 5b (though a short drive from a…
The northeast is having its first heatwave of the year, and I thought it was a good time to re-run a piece I wrote about what to do in extreme heat if you don't have air conditioning. Because we all know what heatwaves mean - not just physical stress, health crises and unnecessary deaths from heat, but also blackouts and brownouts as everyone charges up their a/c. So what do you do when the power is out and the heat is on? These suggestions include, I think, the most important strategy - be aware of other people. There are a lot of parallels between dealing with extreme heat and extreme…
I recently wrote about the tragic bushfires in Australia and how it seems to me that it is reasonable to ask if this would have happened without anthropogenic climate changes. Real Climate has the details on this in their latest post: Bushfires and extreme heat in south-east Australia. The post is by David Karoly, Professor of Meteorology at the University of Melbourne in Australia. He identifies four factors in the fire's ferocity - maximum temperatures, relative humidity, wind speeds and the ongoing drought - and discusses the possible role of climate change in each of them. For three of…
Adelaide, South Australia, Australia, is a place that many have told me I must visit (although perhaps not now as they are experiencing record heat). In fact, a twist of science and friendships nearly brought me there for my sabbatical before I had a big change in my life. The University of Adelaide is outstanding (and home of colleague and Astroblog blogger, Ian Musgrave), the surrounding wine appellations are world-famous, and the mountains to the northwest would be a combination I'm told I'd be certain to enjoy. Therefore, I was delighted to receive the following e-mail on 3 January from…
