Milli Vanilli "Blame it on the Rain" Meteorology Awards - 2015 Nominees

climate change canada

OUR INSPIRATION - 1989

Milli Vanilli had a hit song "Blame it on the Rain" in 1989 - it was number one for 2 weeks on the U.S. Billboard Hot 100 ! And why not?  It had :

1) Phat beat with that Roland TR-808 groove in the back of the mix with tasty cowbell tinkles - who doesn't need more cowbell from an iconic analog beat box?

2) Catchy lyrics per this excerpt:


Gotta blame it on something
Gotta blame it on something
Blame it on the rain (rain)
Blame it on the stars (stars)
Whatever you do don't put the blame on you
Blame it on the rain yeah yeah

3) High production promotion with a couple of 'singers' delivering it all.

As we all know now, the 'singers' we all saw weren't singing at all, but just lip syncing to recorded tracks telling us to "Blame it on the Rain" because we gotta blame it on something.

OUR NOMINEES - 2015

In honour of Milli Vanilli, CityFloodMap.Com now announces the Milli Vanilli Meteorology Award nominees - those who, with little substance "Blame it on the Rain" when it comes to weather science, extreme value statistics, flood risk assessment, and flood damage reduction policy.  TR-808 drum roll please ...... and the 2015 nominees are:

#1 (Acting) Environment Commissioner of Ontario
Connecting The Dots on Climate Data in Ontario, Toronto, January 8, 2015, The Environmental  Commissioner's Eco Climate Data Roundtable for saying :



"But now “1-in-100 year” storms, which are often the threshold for resilient design, are happening more frequently than in the past." (per summary brochure)

See full details:

Why this is a worthy nominee:

Coles Notes: Environment Canada states there has been no significant change in rainfall over decades. Also old systems built pre-1980's to 1-in-5 year storm level of service will continue to flood as they always have - rain is not more frequent as the data clearly shows.  Runoff has increased though in our cities and watersheds.  And flow conveyance systems are more constrained resulting in more frequent back-ups and damage.

*****

#2 (Acting) Environment Commissioner of Ontario
Feeling the Heat: 2015 Annual Greenhouse Gas Progress Report, July 7, 2015 for saying:



"The report notes that extreme weather associated with climate change has already damaged the province’s infrastructure; for example, intense storms and flash floods in recent years have caused costly damage to provincial roadways and commuter rail lines. And future projections for the province point to an even more unpredictable and unstable climate."  (per release document)

See full details:


Coles Notes:  This GO Train rail line area has always flooded, with records going back to the "Great Flood" on September 13, 1878. But the watershed hydrology has changed and there is more runoff than during the 1981 flood inquiry that noted during the March 21, 1980 flood "Part of the CNR track flooded to the north and east of a point south of Bloor Street."  During the April 14, 1980 flood, after a 5-6 hour period of rain, CNR tracks at the Bloor Street ramp were flooded.  The inquiry report indicates that train operation has halted, or trains were detoured during floods, including December 25, 1979, January 11, 1980, March 21, 1980, April 14, 1980, February 11, 1981 and May 11, 1981. Lack of recent Keating Channel dredging may reduce flow capacity of the river system, aggravating flood risks. SO DREDGE THE CHANNEL! IT'S LIKE A METAMUCIL FLUSH FOR FLOOD PREVENTION!

WAKE UP! The May 29, 2013 flood was worse - higher recorded water level at Todmorden gauge, higher flow rate than July 8, 2013 - but luckily missed trains due to the schedule.

*****

#3 Insurance Bureau of Canada
Municipal Risk Assessment Tool & Telling the Weather Story for saying:

"Extreme weather events that used to happen every 40 years now occur every 6 years. IBC is piloting ground-breaking technology – a tool known as MRAT – to help communities reduce flooding caused by sewer backups....How Does MRAT Fight Urban Flooding? Canada’s weather is changing and it’s hurting communities...." (per IBC website)

See full details:
(well you can't because MRAT has some proprietary information, but you can read about the source of the statement in IBC's Telling the Weather Story in our link below)

Why this is a worthy nominee:

Coles Notes: IBC`s report misreports a theoretical normal bell curve shift for temperature changes as actual Environment Canada weather data and then misreports weather to mean extreme rainfall.


Honourable mentions include those who have repeated the IBC statement that storms that used to occur every 40 years occur every 6 years now, including:

Institute for Catastrophic Loss Reduction
Craig Alexander - TD Economics
thestar.com
cbcnews.ca
Canadian Chamber of Commerce
The Tree - Content for Energy and Climate Communicators
Columbia Institute Centre for Civic Governance
Civic Action
Calgary Sun

Gotta Blame Flooding on Something? And not the rain?  Here you go:

Our letter to the Minister of the Environment of Ontario has some ideas:

Our research into overland flood risk factors is has some ideas as well:

Overall, instead of blaming it on the rain, look to runoff / hydrology changes in our watersheds and urban catchments, and at flow / hydraulics in drainage infrastructure, including the neglected overland flow system.  See the post below on Rain-Runoff-Flow-Flood.

It is noted that the ECO in the 2014 report Looking for Leadership, The Costs of Climate Inaction has repeated the "Weather Story" statement saying:

"For example, the Insurance Bureau of Canada estimates that extreme storms of a magnitude expected to happen every 40 years are now predicted to occur every six years."

Why Flood Damages Are Increasing in Urban Areas in Canada

The important factors that explain why urban flood damages are increasing in Canada.
The only houses that flood directly because of Rain do not have a roof - not many.  Floods occurs because of the Flow of Runoff, not Rain.

Rain intensities are not increasing in Canada, on average, or to any statistically significant degree, in relation to urban flooding (short duration intensities, as opposed to number of days with rain through the year).

Rain turns into Runoff and is influenced by land use development patterns and any mitigation measures that control runoff (stormwater management).  Hydrology ([hahy-drol-uh-jee]) is the study of the rain-runoff transformations.  Stormwater management is a specialized field of Civil Engineering.  Runoff is increasing in urban areas through intensification.

Runoff turns into Flow as it is collected and concentrated in urban infrastructure, or conveyance systems (sewers, overland flow routes).  As Runoff has increased, so has flow, sometimes despite earlier mitigation efforts.

When Flow exceeds the conveyance systems capacity (Rain is above the designed level of service, or Flow capacity is reduced), collected Runoff backs-up, surcharges or spills into homes, causing Floods.  Sometimes, modifications to the conveyance system for environmental protection (prevent sewage splils) reduce capacity and contribute to Floods.

Rain storm intensity not increasing shows how junk reporting has metastasized through media, economic reports and policy statements, ignoring and misrepresenting Environment Canada data

Rain - cbc news reports bogus insurance industry claim on increasing storm frequency shows that no fact checking occurs when reporting even the most outrageous claims on insurance flood damages (i.e, that there are 20 times more storms now)

Runoff and Flow - Go Train flooding not new per 1981 provincial inquiry highlights incorrect explanation of recent rail flood damages by climate change, as explained decades ago to Premier Davis using science and engineering principles like runoff hydrology (Don Watershed development) and flow hydraulics (Keating Channel dredging)

Flow -  Toronto overland flow factors affect flood risk includes recommendations on urban flood hazard management, backed up by informative new overland flood risk mapping.  Given this exposed correlation of historical basement flooding incidents and overland flow risks, you would be right to question whether insurance companies have indirectly, inadvertently insured overland flood risk in conventional sewer back-up policies. Flow is a continuum from flood plains to floor drains, whether property insurance policies try to make a distinction or not.

 And Connecting dots on climate change shows how infographics and anecdotes have replaced data and statistics in the myopic explanation of flooding that points to climate change, and ignores factors in the rainfall-runoff process (watershed development, stormwater management), and runoff conveyance (infrastructure design and operation) and ignores Environment Canada rain data.






Bogus statements on storms in cbcnews.ca report - 'twenty times more storms' in Windsor-Essex

Update: CBC has updated their story in response to our complaint on the accuracy in the original news report.  Thank you for listening CBC Windsor.  Here is the clarification offered:

Clarifications

  • This story has been updated to include comment from Environment Canada on heavy rainfall events in the Windsor region.
    Nov 20, 2015 12:06 PM ET
The highlighted text below has been added to the report.  Note, we provided information to CBC on rainfall trends between 1946 and 2009 as shown below, and it appears Environment Canada has also reviewed trends from 1953 to 2012 to respond to the complaint :

"A lot of it has to do with the frequency of the storms and I think you could even extrapolate that it's got to do with climate change," ...

 ... "we're getting 20 times more storms now than we were 20 years ago."

However, Environment Canada says it has recently looked at the trends in heavy rainfall events and there were "no significant changes" in the Windsor region between 1953 and 2012.

It appears that the interviewee based statements on an insurance industry newsletter.  

Excerpt. CBC response to complaint on storm statistics and frequency causing flooding.

****** Updated Post Below *******

(Originally) no fact checkers at cbcnews.ca this week for a story on storm frequency.  Hence bogus statements  introduce an article on why storm damage claims are increasing:

"The more storms Mother Nature dishes out, the more problems homeowners have with their sewers and basements.
And with an increasing frequency of storm events, insurance companies serving homeowners in Windsor and Essex County are taking a harder line on what coverage they can offer and what their customers must pay to receive it."
And the interviewee seems to back this up by doubling down:
"On a statistical basis ... "we're getting 20 times more storms now than we were 20 years ago.""
Well this embodies the quote about there being lies, damn lies and statistics, because the true statistics on rainfall frequency shows the opposite in Windsor-Essex, from whence many a Tecumseth tall tale teller hail.  Environment Canada statistics show us decreasing intensities - i.e., REAL downward trends in annual maxima for rainfall volumes over a range of durations from 5 minutes to 24 hours. 

climate change toronto

This data is freely available to anyone with an internet connection, and is readily applied by those water resources engineers and municipal drainage designers who work with rainfall statistics as part of their professional practice.  Certainly, storms did not increase twenty times and storms cannot explain the change in insurance claims over the past decades.  Storm intensities are decreasing at the Windsor Airport gauge (station ID 6139525) since the mid 1940's (CBC has clarified through Environment Canada correspondence that "there has been no significant change in rainfall events over several decades").  Other possible factors affecting damages:
1) Runoff increased due to development
2) Overland drainage systems have been compromised
3) More expensive stuff in basements
No doubt cbcnews.ca needs better fact checking (some fact checking?).  There is no QA/QC in reporting on extreme weather in Canada.  Sad.  It took all afternoon to summarize the trends in rain intensity for climate stations across Canada in one simple graph, but its not hard to do because Environment Canada does the trend analysis on the raw data and categorizes trends as significantly significant or not in their publications - this summary of rain intensity trends is for 565 stations:

climate change canada
Real climate data from Environment Canada shows no change in historical rainfall intensities.
 The statistics for 565 weather gauges show us the following:
  • there is no statistically significant change in rainfall intensity for 86% of data points
  • there is a statistically significant decrease for 2 to 3% of data
  • there is a statistically significant increase for 3 to 5% of data
  • there is incomplete data for trend analysis 7% of the time
  • for shortest duration rainfall that affects urban flooding, just less than 3% of data shows increases in intensity (5 minute intensity increases at 2.7% of gauges)
If the rainfall frequency distribution is stationary (no change), after a long, long time, half of gauges would have increases and half decreases.  Looking at all data points including the non-significant trends what are the changes? :
  • 41% of data showed a decrease in intensity
  • 52% of data showed an increase in intensity
  • 7%  of data was incomplete (no data trend)
So it is not like there are a lot of increases just shy of statistical significance ... its a fairly even split for a random sample. I redid the analysis screening out rain gauge records shorter than 20 years (the data above was 10+ years) and using only gauges whose record ended in since the year 2000 to focus on newer data and more long-term reliable records.  For these screened 345 gauges we find more or less the same:
  • 42% of data showed a decrease in intensity
  • 56% of data showed an increase in intensity
  • 2%  of data was incomplete (no data trend)
So has Mother Nature dished out more rain, or have developed municipalities dished out more runoff over the decades?  Saying there are 20 times more storms than there were 20 years ago is just plain wrong - in fact it is a 'worse-than-useless' statement because it diverts attention from real risk factors and effective management approaches.  Canada needs evidence-based policy on flood risk management and open data to support better decision making.  The real Environment Canada data is available for download here:

Environment Commissioner of Ontario infographic non-data

The cbcnews.ca data  is available in the Government of Ontario infographic at right.  Notice there is no real data there, no labels on the access, no data sources, nothing really.  But it seems quite definitive with the exclamation point and all.

Further Government of Ontario climate data is available in the rubber-chicken graph below, because data does not matter to those who do not believe in evidence based policy, science, statistics, or informed decision making.

Government of Ontario climate data.  Oh my, it is getting big and scary just like the infographic and cbcnews.ca foretold!
