Australia’s Sizzling Summer of 2019

This summer Australia shattered its heat records, with temperatures nationwide 3.8°F, above the 1961-90 average, according to Australia’s Bureau of Meteorology (BOM).  In a summary put out by the Bureau, they summed it up this way, “Mean and maximum temperature for the season broke previous records by large margins; both almost one degree above the record set in 2012–13.”  Here are some of the other “highlights” from the government’s summer heat summary report:

  • Exceptional heatwaves occurred during early December on the tropical Queensland coast and across much of Australia during December and January
  • Significant fires affected eastern Queensland, large parts of Tasmania, eastern Victoria, northeastern New South Wales, and South West Western Australia
  • Rainfall was below to very much below average across most of Australia, but above average for large parts of northern Queensland
  • Severe tropical cyclone Owen caused flooding in the Queensland’s eastern Cape York Peninsula in mid-December, and contributed to thunderstorms over southeast Australia, with flooding in western and northern Victoria
  • Dust storms originating from Central Australia affected the East on several occasions; one storm stretched over 1500 km
  • And two temperature jaw-droppers: 96.6°F, which was the overnight low temperature on Jan. 17 in New South Wales and was the country’s hottest nighttime low on record, and 104°F, which was the temperature reached or exceeded in Canberra for 4 consecutive days, something that had not occurred since records began there in 1939.

The implications are far-reaching. For example, Reuters reported that Australia’s severe heat resulted in several industries taking a hit, including the $4.4 billion wine industry with grape yields set to drop to the lowest in years.  Wildfires are continuing to torch the Australian state of Victoria — firefighters struggled to battle 25 blazes there on Sunday, with more than 2,000 firefighters, water-bombing aircraft and volunteers on the front lines.

Why This Matters: This is continuing a string of years of extreme summer heat in Australia, and the Bureau of Meteorology there stated that the “pattern is consistent with observed climate change….This means that natural climate variability sits on top of this background warming, and temperature records are likely to continue to be broken in the coming years.”    Those high temperatures — exceeding both high temperature and low temperature records, will impact human health as well, not to mention cause power demand to increase for air conditioning.  Temperatures like these are beyond uncomfortable, they can be deadly, and many there are not prepared for them.  There will be an election in May in Australia and many are predicting, particularly after this hot summer, that climate change will be a key issue there too.

Ho Ho No: Ice on Top of Snow — Bad for Humans and Reindeer Too

An Associated Press report earlier this week went viral because it hits a little too close to home this time of year — unusual weather patterns are causing reindeer to go hungry because as rain (as opposed to snow) falls during the winter in the Arctic, it creates thick layers of snowy ice that blocks their access to food.  In much of the U.S. we will likewise be battered with a “parade” of combo snow/ice storms for the days until Christmas, snarling all kinds of travel plans.

Why This Matters: Ice is only good in Disney movies.

Attribution Science Connects Extreme Weather to Climate Change

If you read my (Miro’s) Bright Ideas op-ed over the weekend then you saw that the tired argument of “yes the climate is changing, but we don’t know how much humans are contributing to it” has been around for at least 20 years. Luckily, that excuse for inaction is finally starting to wear thin as […]

Thanksgiving Travel: Weather Could Cause Problems, Meanwhile NOAA Leader Still “Acting”

Forecasters are calling for three major storms this week to snarl travel plans for much of the country — with cities from Denver to Detroit expecting snow, freezing rain and soaking rain and winds on Tuesday into Wednesday, the heaviest travel day of the year.  And in other weather news, the Trump Administration’s nominee to be the Administrator of the National Oceanic and Atmospheric Administration (NOAA) is withdrawing his name from consideration — he was nominated but never confirmed — leaving the Acting Administrator to continue to lead the agency.

Why This Matters:  This will be the longest time NOAA has gone without a confirmed Administrator in its history.
