It introduces the Accumulated Winter Season Severity Index, which seeks to combine several factors that make winter miserable: temperatures, snowfall and a winter season&#39;s duration. As of March 17, the index would suggest the 2013-2014 was the third-worst since the 1950s. Additionally, the season ranks third-highest when it comes to&nbsp;</em><em><a href="#snow">snowfall</a>&nbsp;measured from Dec. 1 to the end of February.&nbsp;</em><em>Continue reading to see how recent decades (not just this season) compare to those of Chicago&#39;s past when it comes to&nbsp;<a href="#temps">temperature</a>,&nbsp;<a href="#windchill">wind chill</a>,&nbsp;<a href="#extremes">extreme events</a>,&nbsp;<a href="#grey">grey skies</a>, and&nbsp;<a href="#city">city response</a>.&nbsp;</em></p><p>Maybe you&rsquo;re still warming up from January&rsquo;s <a href="http://www.wbez.org/tags/polar-vortex">polar vortex</a> &mdash; replacing your car&rsquo;s battery or repairing the plastic insulation taped into your window frames &mdash; but bear with us: What&rsquo;s the worst part of winter?</p><p>Curious City recently got a related question from Edgewater resident Tracey Rosen:</p><p style="text-align: center;"><em>&ldquo;Is it&nbsp;true&nbsp;that Chicago winters were worse than they are now?&quot;</em></p><p>I asked Illinois State Climatologist <a href="http://www.wbez.org/results?s=jim%20angel">Jim Angel</a>, who pointed out Tracey&rsquo;s query raises questions of its own.</p><p>&ldquo;I have wrestled with that question before &mdash; what constitutes a &lsquo;bad&rsquo; winter. Is it the snow, the cold temperature, the length of the season, etc.,&rdquo; Angel said in an email. &ldquo;I can tell you that by most measures the winters in the late 1970s were the worst.&rdquo;</p><p>But it depends on what you deem &ldquo;worse.&rdquo; Would that be a winter with more snow? One with more big snowstorms? Should the coldest winter count? Or maybe one where city services like public transportation freeze to a halt?<img alt="" class="image-original_image" src="http://www.wbez.org/system/files/styles/original_image/llo/insert-images/tracey%20rosen%20WEB.jpg" style="float: right; height: 195px; width: 260px;" title="Question-asker Tracey Rosen, who asked Curious City if Chicago winters were really worse than they are now. (Photo courtesy Tracey Rosen)" /></p><p>To answer Tracey&rsquo;s question, we broke down some of the more universal descriptors of a &ldquo;bad&rdquo; winter and found out which years had it the worst (<a href="#temps">temperature</a>, <a href="#windchill">wind chill</a>, <a href="#snow">snowfall</a>, <a href="#extremes">extreme events</a>, <a href="#grey">grey skies</a>, and <a href="#city">city response</a>).</p><p>Along the way we found out what effect a brutal Chicago winter has on the people who live here and how some of them cope. But we also struck gold when we found there&rsquo;ve been attempts to scientifically assign a value to each winter&rsquo;s particular blend of meteorological misery; this would be <a href="#misery">one measurement to rule them all</a> &mdash; or at least allow us to compare a snowy, but mild winter to one that was cold but had clear skies.</p><p><strong><a name="misery"></a>Winter and our discontent</strong></p><p>A scientist with the National Oceanographic and Atmospheric Association researches the question we&rsquo;re asking: How do you judge a severe winter? Barbara Mayes Boustead developed the <a href="https://ams.confex.com/ams/93Annual/webprogram/Paper218513.html" target="_blank">Accumulated Winter Season Severity Index</a> (AWSSI, pronounced &ldquo;aussie&rdquo;) to mathematically pin all of this down.</p><p>AWSSI assigns points to each winter based on its daily temperature maximums and minimums, its snowfall and lingering snow depth, and its length. The index designates the &quot;start&quot; of winter when the first snow falls, or the first high temperature that&rsquo;s 32 degrees or colder. If neither of these happens before Dec. 1, then that&rsquo;s when the index starts counting. The &quot;end&quot; of winter is set by the last snowfall date, the last day with one inch or more of snow depth, or the last day when the maximum temperature is 32 degrees or colder. If none of these occurs after February, then the last day of February is the end of winter.</p><p>The winter of 2013-2014 &ldquo;began&rdquo; in Chicago on Nov. 11, according to AWSSI, with 0.4 inches of snow. That&rsquo;s close to the average start date of Nov. 13, which means it&rsquo;s unlikely to rank as one of the city&rsquo;s longest winters &mdash; several have stretched five or six months. In 2006, winter started on Oct. 12 and didn&rsquo;t end until April 12.</p><p>The following chart represents the trajectory of misery within specific seasons.

The red and blue areas are periods where warmer and cooler temperatures, respectively, dominated. A relatively cold period for northeastern Illinois (compared to its average winter temperature of 25.1 degrees Fahrenheit) began in 1976 and continued through 1987. Relatively mild winters, average-temperature-wise, immediately followed, from 1988 through 2006.</p><p><a href="http://www.crh.noaa.gov/lot/?n=chi_records">Chicago&rsquo;s coldest month was January 1977</a>, with an average temperature of just 10.1 degrees Fahrenheit. The coldest single temperature reading, however, was eight years later. On January 20, 1985 the thermometers hit 27 degrees below zero. And Chicago&rsquo;s coldest year on record was 1875, with an annual average temperature of 45.1 degrees.</p><p>On Jan. 26, a press release issued by Gov. Pat Quinn&rsquo;s office reminded Illinoisans that some freezes can be fatal:</p><p>&ldquo;Extreme cold temperatures are dangerous and can be deadly. Since 1995, more than 130 fatalities related to cold temperatures have occurred in Illinois, making it the second-leading cause of weather-related deaths in Illinois in the past two decades.&rdquo;</p><p><iframe align="right" allowfullscreen="" frameborder="0" height="300" scrolling="no" src="//www.youtube.com/embed/zZVElJBkO7Q?rel=0" width="405"></iframe></p><p>We&rsquo;ve had a few bouts of persistently cold temperatures this winter, including one that approached a length not seen since 1996, when a 66-hour run of subzero temperatures became the area&rsquo;s second longest. That record belongs to a 98-hour period beginning on Dec. 26, 1983.</p><p>Chicago&rsquo;s temperature as measured at O&rsquo;Hare Airport has dropped below zero 15 times this winter, <a href="http://blog.chicagoweathercenter.com/category/tims-weather-world/">as of</a> the end of January &mdash; that&rsquo;s twice the long-term average. That puts us not far from the winter of 1978-79, when the city saw subzero temperatures 23 times.</p><p>The1970s were indeed cold and snowy, enough to be a point of pride for the Chicagoans who weathered those years.</p><p>&ldquo;When people comment and say, &lsquo;Oh winters are not as cold as they used to be,&rsquo; it&rsquo;s a way to say, &lsquo;My Chicago is not what it used to be,&rsquo;&rdquo; said our question asker, Tracey Rosen. &ldquo;You know, the identity of the Chicago that I drew from is not what these young people are doing with Chicago.&rdquo;</p><p>Statistically speaking, though, the winter of 2013-14 could give young Chicagoans an idea of what their late 70s forbears had to deal with. Again, Barbara Mayes Boustead&#39;s &ldquo;winter severity index&rdquo; ranks this season &mdash; as of March 17 &mdash; the city&rsquo;s third-most &ldquo;severe&rdquo; since the 1950s.&nbsp;</p><p><strong><a name="windchill"></a>Wind chill: The wind blows cold</strong></p><p><img alt="" class="image-original_image" src="http://www.wbez.org/system/files/styles/original_image/llo/insert-images/Meridith112%20st%20charles%202014.jpg" style="float: left; height: 230px; width: 260px;" title="Wind chills can add some misery to any Chicago winter.

But, Chicago&rsquo;s coldest wind chill ever was -82 degrees. It came on Christmas Eve, 1983.</p><p>The wind in the term &ldquo;wind chill&rdquo; can compound a winter season&rsquo;s misery. For example, gusts can make it hard to clear snow. Tim Gibbons has owned Tim&rsquo;s Snowplowing, Inc. for 30 years. They&rsquo;re located in Humboldt Park now, but Gibbons started plowing in the neighborhood he grew up in and still calls home &mdash; North Center. Lately wind has been making his job difficult.</p><p>&ldquo;What we&rsquo;ve had is the phenomenon of a light, dry snow followed by a heavy-wind vortex, as these systems pass, that is taking that same light, dry snow and moved it back across whatever surface it was on,&rdquo; he said. &ldquo;If it was a wet, heavy snow &hellip; it&rsquo;s less likely to be driven by any wind.

Average snowfall for winters in the 1970s was just over 40 inches per year.

And, despite some notable snowfalls, some key operations are able to keep up. According to climatologist Jim Angel, this winter we have not gone more than about four days in a row with snow cover at O&rsquo;Hare. &quot;Of course,&quot; he adds, &quot;some of the piles of snow in parking lots are lasting a lot longer.&quot;&nbsp;</p><p><strong><a name="extremes"></a>Finding the extremes</strong></p><p>Just as averages can blur individual data points, looking at total snowfall can miss the difference between a quaint winter wonderland and <a href="http://en.wikipedia.org/wiki/Hoth">Hoth</a>: huge snowstorms.</p><p><img alt="" class="image-original_image" src="http://www.wbez.org/system/files/styles/original_image/llo/insert-images/winter%20%20Forest%20Preserve%20District%20of%20Cook%20County%20Records%2C%20University%20of%20Illinois%20at%20Chicago%20Library.jpg" style="float: right; height: 241px; width: 300px;" title="One good thing about lots of snow? Tobagganing. (Photo courtesy Forest Preserve District of Cook County Records, University of Illinois at Chicago Library)" />Since 1886, there have been 42 storms that brought 10 inches of snow or more to Chicago, said Ben Deubelbeiss of the National Weather Service. (The most recent one was in 2011, when <a href="http://www.wbez.org/tags/2011-blizzard">more than 20 inches of snow blanketed the city, stranding cars on Lake Shore Drive</a>.) Every decade has had at least one such storm, but the 1890s leads the pack with seven. The 1970s is a close second, however, with six snowstorms that dropped at least 10 inches. The 1960s were third, with five.</p><p>How about individual years? It&rsquo;s rare for any given year to have more than one Chicago snowstorm that big. In fact, Deubelbeiss said since NWS&rsquo; records began in 1886, only five years have had two storms with more than 10 inches of snow each: 1894, 1895, 1896, 1978, and 1970.</p><p>Here are Chicago&rsquo;s ten biggest snowstorms:</p><p>1. 23.0 inches Jan 26-27, 1967<br />2. 21.6 inches Jan 1-3, 1999<br />3. 21.2 inches Feb. 1-2, 2011<br />4. 20.3 inches Jan 13-14, 1979<br />5. 19.2 inches Mar 25-26, 1930<br />6. 16.2 inches Mar 7-8, 1931<br />7. 15.0 inches Dec 17-20, 1929<br />8. 14.9 inches Jan 30, 1939<br />9. 14.9 inches Jan 6-7, 1918<br />10. 14.3 inches Mar 25-26, 1970</p><p>Chicago&rsquo;s single <a href="http://www.chicagotribune.com/news/politics/chi-chicagodays-1967blizzard-story,0,1032940.story">biggest snowstorm</a> occurred on Jan. 26, 1967. At 5:02 a.m. it began to snow. It snowed all day and night, until 10:10 a.m. the next day, dropping 23 inches of snow in all. Looting broke out, some people were stranded overnight at work or in school, and 26 people died as a result of the storm.</p><p>(Not everything was bad about the massive snowfall. Chicago Public Library researchers said <a href="https://web.archive.org/web/20040402070119/http://www.chipublib.org/004chicago/disasters/snowstorms.html">some of the 75 million tons of snow that fell that year made its way to &quot;as a present to Florida children who had never seen snow before.&quot;</a>)</p><p>Cold temperatures and periodic snow continued for the next ten days, aggravating attempts to cleanup after the storm and get city services back to normal. All that was made a bit more shocking by the fact that just two days before the storm, the temperature had reached a record 65 degrees.</p><p><strong><a name="grey"></a>Grey skies: The not-so-fluffy stuff</strong></p><p><img alt="" class="image-original_image" src="http://www.wbez.org/system/files/styles/original_image/llo/insert-images/Jon%20Pekelnicky.jpg" style="float: left; height: 278px; width: 370px;" title="On average, Chicago gets sunshine 54 percent of the time.

One thing he keeps track of is the amount of sunlight that shines each day.</p><p>Of the years tracked in Wachowski&rsquo;s records, 1992 had the most winter days (November through February) with no sunshine &mdash; 46 of those 121 days registered zero percent on Wachowski&rsquo;s sunshine recorder. Of the 25 gloomiest years using this measure, only five have occurred since 1990.</p><p>On average, Chicago only gets sunshine 54 percent of the time. That annual average has stayed about the same for 30 years, Wachowski said.</p><p>In the winter, it&rsquo;s even grayer. Winter months typically get sunshine less than 44 percent of the time. In November 1985, the sun only shined on average 16 percent of the time.</p><p>That&rsquo;s not surprising to people with Seasonal Affective Disorder, like <a href="http://arlenemalinowski.com/not_normal.htm">Arlene Malinowski</a>. SAD, as it&rsquo;s known by its acronym, afflicts about six percent of Americans. Malinowski&rsquo;s an actor and playwright who <a href="http://www.huffingtonpost.com/arlene-malinowski-phd/seasonal-affective-disorder_b_4551574.html">has written about</a> the depression that sets in during long, gray winters.</p><p>&ldquo;You&rsquo;re tired all the time, there is this decreased energy, a real lack of focus and productivity. It is more than just, &ldquo;oh blah I&rsquo;m having a bad day&rdquo; &mdash; it is a deep, deep sadness and emptiness,&rdquo; she said. &ldquo;Last week I looked out the window and the streetlights were on at 11 o&rsquo;clock in the morning, and I thought, &lsquo;This is not right.&rsquo;&rdquo;</p><p>But there&rsquo;s a light at the end of the tunnel, literally.

But when city services grind to a halt, the agony of a winter storm can go on for much longer.</p><p>When 20.3 inches of snow fell on Chicago Jan. 13-14, 1979, <a href="http://www.wbez.org/blog/best-game-town/great-lsd-gridlock-blizzard-1979-redux">it snarled both city streets and Mayor Michael Bilandic&rsquo;s reelection ambitions</a>.Jane Byrne went on to win the municipal election less than two months later, <a href="http://www.npr.org/2010/12/30/132478152/Political-Lessons-From-Old-Chicago-Blizzard-Still-Linger">and the politics of snow would become associated with her term forever</a>.</p><p>New CTA lines running in expressway medians choked on all the de-icing salt. Unlike previous storms, the 1979 blizzard saw massive closures of rapid transit lines, in addition to buses, cars and flights.</p><p><a href="https://www.youtube.com/watch?v=cvFwjhpkjL0">WBBM Channel 2 News did a Special Report</a> on the city&rsquo;s response during that storm&rsquo;s aftermath. In his intro to the segment, newsman Bill Kurtis described a scene that may sound familiar to those who have weathered more recent blizzards:</p><p>&ldquo;Side streets still unpassable. Public transportation snarled. Expressways buried. O&rsquo;Hare Airport closed for one of the few times in its history. This is turning out to be Chicago&rsquo;s winter of discontent, alright.&rdquo;</p><p>About O&rsquo;Hare closing &mdash; Chicago Department of Aviation spokeswoman Karen Pride said while they always have staff on hand to maintain the airport, winter weather has temporarily knocked out all available runways on several occasions. There were &ldquo;nearly half a dozen&rdquo; such occasions in the 1970s and 80s, Pride said, but that hasn&#39;t happened since.</p><p>Another major blizzard struck the Midwest in 1999, dropping <a href="http://www.ncdc.noaa.gov/oa/climate/extremes/1999/january/blizzard99.html">22 inches of snow on Chicago</a> before temperatures plummeted to -20 degrees or lower in parts of Illinois on January 3 and 4. The National Weather Service ranked it as the second worst blizzard of the 20th century, behind only the blizzard of 1967.</p><p>Later that month in 1999, President Bill Clinton declared a disaster area in half of Illinois&rsquo; counties. Areas of Indiana were also declared disaster areas. The Midwest storm caught Detroit off guard but, <a href="http://www.ncdc.noaa.gov/oa/climate/extremes/1999/january/blizzard99.html">according to Stanley A. Changnon of the NCDC</a>, &ldquo;Chicago was prepared. The city put 850 snow removal trucks on the streets (240 is the normal number for heavy snow).&rdquo;</p><p>The 1999 storm was slightly larger than the one in 1979, at least in terms of snowfall, but it doesn&rsquo;t carry the weight of a mayor&rsquo;s political career. It did, however, set some records. Lake Shore Drive was shut down altogether for the first time in history, and Interstate 65 in Northwest Indiana was also closed. Chicago Public Schools extended winter break by two days. By Jan. 9, one week after the storm, <a href="http://www.examiner.com/article/chicago-s-11th-year-anniversary-of-the-1999-new-years-snowstorm">only about half of Chicago students were back in class</a>.</p><p>Our most recent massive snowstorm &mdash; the 20.2-inch blizzard of 2011, responsible for the city&rsquo;s third highest snowfall on record &mdash; shares some things with its 1999 predecessor. <a href="http://www.reuters.com/article/2011/02/03/us-weather-chicago-idUSTRE71180W20110203">Chicago Public Schools were again closed</a>, for the first time since 1999, and cars were once again stranded on Lake Shore Drive.</p><p><strong>Climate change</strong></p><p>In terms of cold and snow, generally speaking, the trend is toward milder winters.

It was really quite an interesting means of transportation.&rdquo;</p><p>Now that he&rsquo;s older, he admits business can be stressful during extreme winters. But he said that&rsquo;s not the whole story. His advice? People should help each other shovel out their cars (he&rsquo;s no fan of dibs), and remember that even the coldest winter&rsquo;s only temporary.</p><p>&ldquo;I think it&rsquo;s time we all take a deep breath, count our blessings, soldier on in the true &lsquo;I will&rsquo; spirit of Chicago,&rdquo; Gibbons said. &ldquo;Hearty people live in Chicago. We get through our winters and we celebrate our summers as a result.&rdquo;</p><p><em><a href="http://cabentley.com/">Chris Bentley</a> is a reporter for Curious City.

This highly networked global society means record numbers of the world&#39;s population are moving into the middle class, especially in Asia. However, as illustrated by the global financial crisis, interconnectedness carries risks of contagion as well. <strong>Kishore Mahbubani</strong> argues that new policies and approaches to governance are needed to solve pervasive problems such as financial volatility and health and climate issues. How does Asia, which accounts for over 60 percent of the world&rsquo;s population and a significant portion of the emerging global middle class, fit into this era of convergence?</p><div>Kishore Mahbubani is the dean and professor in the practice of public policy at the Lee Kuan Yew School of Public Policy at the National University of Singapore. From 1971 to 2004 he served in the Singapore Foreign Ministry, where he was permanent secretary from 1993 to 1998, served twice as Singapore&rsquo;s ambassador to the UN, and in January 2001 and May 2002 served as president of the UN Security Council. Mahbubani is the author of Can Asians Think?, Beyond the Age of Innocence: Rebuilding Trust Between America and the World, and The New Asian Hemisphere: the Irresistible Shift of Global Power to the East. Foreign Policy and Prospect magazines have listed him as one of the top 100 public intellectuals in the world, and in 2009 the Financial Times included him on their list of the top 50 individuals who would shape the debate on the future of capitalism.</div><div>&nbsp;</div><div>His most recent book is,&nbsp;<em>The Great Convergence: Asia, the West, and the Logic of One World.</em><br />&nbsp;</div><div><div class="image-insert-image "><img alt="" class="image-original_image" src="http://www.wbez.org/system/files/styles/original_image/llo/insert-images/CCGA-webstory_8.jpg" title="" /></div></div><p>Recorded live Wednesday, March 6, 2013 at The Chicago Club.&nbsp;</p></p> Wed, 06 Mar 2013 11:28:00 -0600 http://www.wbez.org/series/chicago-amplified/asia-and-great-convergence-106669 Al Gore's crystal ball http://www.wbez.org/blogs/chris-bentley/2013-02/al-gores-crystal-ball-105446 <img typeof="foaf:Image" src="http://llnw.wbez.org/main-images/Al Gore.jpg" alt="" /><p><p><iframe frameborder="0" height="392" scrolling="no" src="http://www.ustream.tv/embed/recorded/29128342?v=3&amp;wmode=direct" style="border: 0px none transparent;" width="480"></iframe><br /><a href="http://www.ustream.tv/" style="padding: 2px 0px 4px; width: 400px; background: #ffffff; display: block; color: #000000; font-weight: normal; font-size: 10px; text-decoration: underline; text-align: center;" target="_blank">Video streaming by Ustream</a></p><p>Al Gore has been thinking. Since the former Vice President&rsquo;s fateful 2000 presidential bid, he has tried <a href="http://www.goodreads.com/author/list/5658.Al_Gore?auto_login_attempted=true">writing</a>, <a href="http://www.npr.org/templates/story/story.php?storyId=5441976">documentary filmmaking</a>, <a href="http://www.npr.org/2013/01/03/168508578/al-gores-current-tv-sold-to-al-jazeera">broadcast journalism</a>, and <a href="http://www.telegraph.co.uk/earth/energy/6491195/Al-Gore-could-become-worlds-first-carbon-billionaire.html">venture capital</a>&nbsp;&mdash; among other things &mdash; largely to keep one message in the national conversation: climate change is a serious and immediate threat to society.</p><p>That campaign has made his name an epithet in some conservative circles, while many typically left-leaning climate activists view him as somewhat of an icon. Gore has apparently grown accustomed to his assumed role as cultural touchstone, bestowing his new book, which he discussed at the Chicago Council on Global Affairs Friday, with the sagely title <em>The Future</em>.</p><p>Six factors will drive change in the years to come, Gore said, and the ability of society to cope with them will determine its fate.</p><p>Gore considered many topics &mdash; he jumped from cataloguing advances in life sciences (goats that produce spider silk) to globalization and the <a href="http://www.radiolab.org/2013/feb/05/million-dollar-microsecond/">mania of modern high-speed trading</a> &mdash; but he ultimately deferred to the democratizing power of the internet to inspire individual action and organization.</p><p>&ldquo;Short-termism,&rdquo; he said, has come to dominate political planning, while a two-dimensional view of economic growth has served as &ldquo;a mental shortcut&rdquo; preventing the emergence of a sustainable way forward.</p><p>&ldquo;We&rsquo;re going to see growth that wrecks our supply of freshwater and topsoil,&rdquo; he said, &ldquo;that destroys the web of living species with which we share this land and on which we depend.&rdquo; He likened current inaction on climate change to 19<sup>th</sup> century city-dwellers tracing the cause of cholera to contaminated drinking water, yet refusing to cap or abandon the poisonous well.</p><p>Gore levied much of the blame on a political system corrupted by economic disparity and unequal political access.</p><p>He said growing up he knew the battle for civil rights had been won when he heard people standing up against off-hand racist remarks. He placed his faith for the future in the power of such &ldquo;individual conservations,&rdquo; touting the disruptive power of the internet, where he said ideas trump clout.</p><p>&ldquo;New reform movements are thriving on the internet, leading to dramatic change,&rdquo; Gore said. &ldquo;I know we can win conversations about the future.&rdquo;</p></p> Sat, 09 Feb 2013 09:00:00 -0600 http://www.wbez.org/blogs/chris-bentley/2013-02/al-gores-crystal-ball-105446
