Climate change will knock one-third off world economy, study shows

Umm chuck, hate to be a science denier and all that, but if emissions are caused by burning oil and oil is derived from decayed plant matter from millions of years ago and plants absorb CO2 through their leaves and branches, wasnt all that CO2 already in the atmosphere back then.

And wasn't there an explosion of life to take advantage of the beneficial levels of co2? Everything grew bigger and better and with more variety, and inhabited more of the Earth.

So Crop, you have heard of the natural causes of climate change?

Just give cc. time to think about what he would tax us on to handle natural causes of climate change.

Huh?

Slow natural climate change is not a risk compared to relatively rapid and unprecedented human caused climate change that could send us into uncontrollable irreversible climate change.

And there is no evidence of a return to the glaciers anytime in the next several thousands of years unless an asteroid or super volcano erupts.

And if that happens you will have bigger things to worry about!

You and I will be long dead.

Chuck, you really should study some climate history before making a fool of yourself in public. The pace of natural climate change throughout geological history has been breathtaking at times. Our current climate is so stable and benign compared to much of History that our ancestors wouldn't recognize how good we have it.
Check out the book by Michael Fagan about the little ice age. He is a hardcore climate change supporter just like you, so you won't be offended when you read it.

More human caused climate change denial?

More CO2 will be good for us?

Have you considered responding to my actual post?

And then the rains return in the natural 20 year cycle across the prairies , from drought to rains as the natural changes occur in the La Niña to El Niño…

[furrowtickler]

Subsoil moisture levels being replenished in all areas in western Canada , except far NW Alberta and NE BC for now
although some areas very wet now , most areas the crop is in or will get in the next two weeks as a drier pattern will set up now after the full moon .
will be a struggle for some areas for sure as they are very wet now .
Drought crop insurance payments won’t be even mentioned by fall and the high crop insurance payments will be added to provincial general coffers with not a word .
life will carry on

Weather is still going to vary from year to year. And its great there is more moisture this year.

But climate is measured over 30 year periods. And we have an ongoing decline in precipitation in many areas for several years along with often higher temperatures and more drying.

A few weeks won't change or make up for the past moisture deficit.

[furrowtickler]

A few weeks of moisture already has made up moisture deficits in 90% of western Canada , as it did in the western U.S. last year and all through the mid west US the past 2 weeks .

[chuckChuck]

Not the deficit for the last 5 years! That would take above average precipitation for several years.

[furrowtickler]

Watch soil moisture maps the next few weeks .

[chuckChuck]

Furrow, Regina and Saskatoon had a 700 mm precipitation deficit from 2018-2023.With several summers of above average temperatures.

The longer term drought doesn't get reversed in one rainy May. But it is still welcome to be sure.


The slow slide into drought

The current Prairie moisture situation is the result of years of ongoing precipitation deficits

Source: Daniel Bezte We had a fairly major storm system on the Prairies last week, but it was not strong enough to warrant major attention.

Manitoba received the most moisture from this system, with widespread 20 to 30 millimetres of rain mixed with snow. The northern half of agricultural Saskatchewan, along with the far eastern regions, also saw totals ranging from five to 15 mm. Parts of southern and central Alberta had precipitation, mostly as snow, with amounts ranging from four to 12 cm.


While this moisture is welcome, it will do little to alleviate drought conditions ([url]https://www.manitobacooperator.ca/news-opinion/news/another-drought-year-maybe-not-so-much/[/url]) that have been developing across the Prairies for several years.
The last time we looked at weather data, I showed it in tables because it seemed the best way to get the information across. This time I created a series of graphs to tease out precipitation. I looked at yearly precipitation for two main centres in each province going back five years (2018-2023).
The first graph shows the precipitation anomaly for each location over those five years, done by adding up precipitation each year compared to the average amount for each year. What jumps out at me is the precipitation deficit in Regina and Saskatoon. Both locations have received 700 mm less than average. Calgary and Edmonton had much lower deficits, around 200 to 300 mm.
The second graph shows yearly precipitation totals for each location compared to average. What jumps out to me right away is that very few locations and years were above average, which shows why the Prairies have been slowly slipping into a longer-term drought.

The third graph shows precipitation at each location over the last five years. Like the first graph, it helps to visualize total amounts without considering averages. Of interest is that totals for Winnipeg, Brandon and Edmonton are close to each other and Calgary is only a little behind. As expected, Regina and Saskatoon received much less precipitation than the other locations, more than a metre less.
The fourth graph breaks total precipitation into yearly amounts. There is not a lot of difference between the years, but 2022 was a wet year for Winnipeg and Brandon.
There is no obvious cause for the build up of drought conditions, such as a couple of super dry years. Rather, the slow lack of precipitation over the past five years has brought us to this point.

We have also seen several summers with well above average temperatures across the Prairies, which increases evaporation and evapotranspiration and makes below average precipitation even worse It will take more than a couple of wet months to bring an end to the drought. Hopefully, with El Nino coming to an end, we will see a shift toward a wetter pattern.
