Global Warming: Seeing the Negative Side of Longer Growing Seasons

Spring Flowers. You can just see the bad happening

Guest essay by Eric Worrall

Even if you believe the predictions of alarmists, climate change is not going to be universally bad; cold countries like Canada and Russia will benefit from longer growing seasons.

But for people who write for The Conversation, nothing good can be allowed to come from global warming.

Longer growing seasons have a limited effect on combating climate change

Climate warming is leading to early springs and delayed autumns in colder environments, allowing plants to grow for a longer period of time during each growing season. Plants are absorbing more carbon dioxide (CO2) as a result of this longer growing season. 

The earlier arrival of spring is fighting climate change by allowing plants to absorb CO2 over a longer period of time and thus slowing the rate at which atmospheric CO2 is rising. What we don’t know is how long can we count on earlier springs and longer growing seasons.

I am a remote sensing scientist who studies the impact of climate change on seasonal cycle of plant activity. Using satellite observations, long-term ground measurements and mechanistic computer models, I also study the impacts of climate change and variability on global land ecosystems and related feedbacks to the atmosphere through carbon cycle.

In addition, in many northern ecosystems, the benefits of warmer springs on increased CO2 absorption is offset by the accumulation of seasonal water deficits. New evidence shows that the increased spring plant growth and earlier start of the growing season actually deplete summer soil moisture and decrease the overall summer time plant growth in boreal and tundra ecosystems. With increasing warming throughout the growing season, summer moisture stress may be exacerbated in the future in temperate, boreal and Arctic ecosystems.

Climate change is leading to warmer and longer growing seasons, reduced snow pack in winter, earlier spring snow melt and soil water depletion. This in turn increases moisture stress on plants and makes forests more susceptible to severe wildfire, which already becoming increasingly frequent and severe in large parts of Canada. Severe fires can release huge amounts of CO2, not only from the burning plant tissues but also from top soils and peat lands.

Read more:

Assuming global warming continues, warmer temperatures might melt a little snow, but Skeptical Science tells us global warming will also increase rain and snowfall, because warmer air can carry more moisture, so the author’s claim that water stress will rise is at best uncertain.

A little warming might even open the far North of Arctic countries to people who currently find the polar climate unbearably cold. Any demographic map of Canada or Russia shows most people cluster along the warm Souther edge of Northern countries, likely because most people can’t stand the long, dark and bitterly cold winters in the far North.

Of course, all of this assumes the warming predicted by climate models will actually occur. Given climate model’s dismal track record of prediction failure, predictions of future global warming are far from certain.

History has shown that, when the data fail to agree with the models, the data are altered to bring them back into line with the models. If there was a downturn in global temperatures, do you really think the powers that be would allow the data to show it?

Is the proper Canadian spelling “eh” or “aye”?

Reply to  DocSiders
May 12, 2020 7:59 am

It’s typically spelled “eh”?” – usually followed by a question mark. It’s either expressed as a question or as the request for an affirmation – as in “Do you agree?”.

I had to drop “eh” when I lived in the USA – I got teased… that is, until I pointed out that the USA-equivalent of “eh?” is the even dumber-sounding “huh?

We declared an international truce at that point, and even agreed to forgive each other for the War of 1812 – where the Americans burned Toronto and we burned the White House. [Everyone in Canada hates Toronto – so we got the better of that deal. Sorry about the White House – you can burn Toronto again if you want – eh?] 🙂

“Huh” is usually interpreted as “please repeat, I did not understand?”

Yes but I got the perfect comeback to someone saying huh, “Huh, hell can’t you hear?” I think saying huh shows ignorance.

I think still the ‘khasee’ (amongst us Codgers) at home.

Not too many years before we moved into our Victorian cottage 30 years ago, there was an outside Water closet and adjoining clothes washroom.

They were served by a well in the garden we discovered when we excavated a 1m deep trench to supply waste, water and electrical services to our summerhouse.

We broke two Kango Hammers trying to remove four bricks from the well to run the pipes through.

Not a traditional well as one would imagine, but a domed affair, built of traditional Victorian brick and lime mortar that, having been buried for probably 50 years before we discovered it, was as hard as Pig Iron.

We did the usual shining torches down it and throwing stones, but never heard one land or splash. It chills me to this day that had we not discovered it, a person could have disappeared down it without trace.

We sealed it with a concrete cover, buried it, and built a deck over it with a hatch to monitor it.

I might be more concerned about having too much of a good thing with expended growing seasons (like during the MWP when agriculture flourished in Greenland) IF WE WERE ACTUALLY seeing longer seasons.

Everybody wears hipboots and lays on multiple defenses against mosquito attack (the mosquitos don’t suck your blood, they carry you off to their village and share with all of the other family, with giant straws). I have walked through summer tundra, both working and for sport, and for someone, ostensibly in possesion of their faculties, to worry about summer soil moisture is profoundly stupid. By the way, Eric, the photo of the summer flowers should be saved for posterity, because, you know, they breathe CO2, or something.

Is it not true that rising CO2 helps plants tolerate drought (by allowing respiratory pores on leaves stay closed more of the time)? They better add this into their models re the summer drying defeating the benefits of a longer growing season.

Just like with covid-19 models, a poor model is worse than no model at all, because a poor model misleads, while with no model, ignorance is correctly understood.

There is this casual assumption without society that university is this semi-mystical centre of excellence and wisdom that selflessly spreads the collected knowledge it has collected to those pure and patience enough to sit wide eyed at their metaphorical feet.

It is not only a honour, but a basic human right to be selected to take part in this important ritual as students so that one day the student can cast off the robes of undisputed cleverness and go out into the great unwashed to lead society into a better, perhaps even progressive, new understanding, also with a six figure starting salary.

The reality is that this is bollocks.

Universities are a business. Threaten them with enough fees and they will ‘teach’ you anything, regardless of practical merit and slap a nice parchment into your hands at the end as a gift to remember them by. Far from being cutting edge, most of their subject matter is by necessity, several years established and while it may be new and exciting to bushy tailed high school leavers, in the real world industry – who probably developed it in the first place – has absorbed and moved on.

While for STEM type subjects university allows graduates a base level with which to enter their industry, in practical terms they are far from being the young Turks that have the new skills required to ensure their employer remains competitive in the challenging and developing world. Instead they will spend the next few years under near constant supervision to ensure they don’t cut themselves on things they were deliberately told not to touch while doing hack work from someone else’s dust covered in tray.

In real terms the only practical benefit of higher education is it keeps the unemployable out of the crowded youth employment market for a few more years. Apart from that they are smug parasites on society and if the ivory education tower crashes anytime soon I will not be shedding tears.

I guess the longer growing season and corresponding reduced soil moisture is why the Great Lakes are at record high levels right now. Of course, less than 10 years ago the lakes were at record low levels due to climate change, so why not have record high levels due to climate change?

BTW, this morning here (SE Michigan) there was another snow flurry. We’ve had mornings with temps below freezing lately. No longer growing season this year.

Nor do I care what side of the debate they are on.

Nor am I interested in femininity being used as an emotional bludgeon. That event should have been dealt with within seconds. If she was breaking the law she should have been tossed in the back of that van and driven to the Police Office for processing.

The kid, assuming it was hers, should have gone with his mother into the van where he could have been taken care of at the Police Office. His father or a responsible adult could then be contacted to collect the child.

Instead we have God knows what kind of man pleading for the child to be given to him.

What we witnessed was far too many cops, dealing with a minor situation badly, because they don’t have a clue what the prevailing law is, and are so scared for their own employment future they are terrified to make a decision.

And we wonder why our streets are teeming with violent criminals and drug users.

“the accumulation of seasonal water deficits.”

What seasonal water deficits? Does this fellow understand that plants have roots? Most plants will extend their roots underground sufficiently to reach the moisture they need. Some of these climate scientists need to actually learn something about farming. You actually do *NOT* want excessive moisture content near the surface. This contributes to a shallow root system that lessens access of the plant to necessary nutrients. Ask anyone who has ever grown a tomato plant and overwatered it. They simply do not produce fruit very well.

“New evidence shows that the increased spring plant growth and earlier start of the growing season actually deplete summer soil moisture and decrease the overall summer time plant growth in boreal and tundra ecosystems.”

What new evidence? boreal ecosystems (i.e. subarctic areas) are not known for plant growth today! They are primarily forested areas. And tundra ecosystems already get little rainfall. They are areas that are largely frozen during most of the year. The growing season in the tundra is so short that plant life consists primarily of mosses, short grasses, and shrubs that grow close to the ground (i.e. needing fewer nutrients). A longer growing season isn’t going to affect this very much.

“Climate change is leading to warmer and longer growing seasons, reduced snow pack in winter, earlier spring snow melt and soil water depletion.”

What reduced snow pack? Where is this happening exactly? What does it matter if the snow melts in April instead of May? And increased plant growth DECREASES evaporation of ground moisture. Higher CO2 levels increases the efficiency of most plants so they need less water thus conserving soil moisture.

Why are none of these beneficial impacts to the ecosystem mentioned?

Tom Abbott

“Climate change is leading to … reduced snow pack in winter, earlier spring snow melt ”

The man is just not in touch with reality. 2019-2020 northern hemisphere non-mountainous snow mass is well above the 30-year 1982-2012 average. Around 700 gigatons greater at the moment.

Forest fires occur wherever there are forests from boreal Canada to the Amazon. Climate has nothing to do with forest fires; availability of fuel has everything to do with it.

Weather is also a factor, but weather is not climate. Fire weather also occurs in every climate zone where forests grow. Even rain forests get some dry weather sometimes, and then they can and do burn. You cannot find a forest that doesn’t have charcoal in the soil.

Offing all the cows and banning SUV’s will not prevent forest fires. Forest management, however, can make forests resilient to fires and lessen the scope and impact. We should spend our tax dollars on forest management instead of silliness like McMaster University. Slash their budget and put the money to good use instead.

Natural forest fires don’t occur in rain forests with no dry season, no matter how much fuel there is.

The much-touted fires in the Amazon are nearly 100 % set by humans.

The cerrado and caatinga south of the Amazon on the other hand are naturally fire-prone and fire-adapted.

Increasing CO2 levels are helping plant respiratory efficiency, reducing the sizes of the stoma on leaves. This results in less evapotranspiration, and greater drought resistance.

This is an excellent point. Coastal WA rainforests like the Hoh have been burned by indigenous peoples (Klallam, Skokomish, Quinault, Hoh, Quileute, and Makah, for instance) for millennia. The huckleberry and salal fields are ample evidence, as well as oral histories and testimonies.

Similarly, the Cerrado and other SA savannas have been burned by the resident natives for thousands of years. The natives also cleared and burned Amazonian rainforests in much the same fashion. The evidence of human presence(terra preta and ancient canals and mound systems) is abundant.

“Natural fire” is a poorly defined concept and must remain so because the amount of historical anthropogenic fire has been so large and has gone on for so long. Nobody knows what the amount of “natural fire” was; it can’t be distinguished from human-set fires. Even today a lightning fire in a landscape managed (or unmanaged) by humans is an artifact of, or conditional response to, prior human impacts and influences.

Another poorly defined concept is “fire adapted”. All forests have experienced fire, and all forest vegetation is thus “adapted” to fire. There are no endemic species that cannot withstand fire; if there were, they wouldn’t be there.

Mike our indigenous tribes here in Australia also have a long history of using fire to there advantage. Even our early settlers learned their techniques. It’s only in fairly modern times that the National Parks were gated up and it became near impossible to remove dangerous trees from your own property, in the name of environmentalism.

People are still mostly the cause of fires though, we had four fires within 7 kilometers of our property that required the fire brigade. That was in a three month period, two were from lit cigarette buts flicked out of the car window, one from a campfire that wasn’t extinguished properly and one from a fencing welder. Sadly too many are lit deliberately.

Lightening isn’t as common as people think. There is a species of bird bird that has been known to pick up twigs with embers burning at one end from a dying fire only to drop them in a different place and start a new fire. It does this to flush out small animals.

May 12, 2020 9:52 am

So when are these dire conditions expected to show up? Because it’s nice and warm here for the past couple weeks, but before that we had a cold early spring and snowpack levels are 130% to 150% of normal.

Northern Maine had a foot of snow last week. I know there are not a lot of folks up there but they would appreciate a little warming. We visits Quebec City for the skiing and the great food. In summer it’s for the sidewalk cafes. I don’t know the French pronunciation of eh. But then, all of my friends up there speak English, many of them a more correct version than my neighbors here in Maine. If we look at history, cold is bad and warming is good. And I’m old enough to remember the coming ice age that the same people who now predict global warming were predicting in 1970. FYI, the biggest snowstorm I remember was in 1952 and the newspapers I was supposed to deliver didn’t arrive for two days from the city 24 miles away.

“New evidence shows that the increased spring plant growth and earlier start of the growing season actually deplete summer soil moisture and decrease the overall summer time plant growth in boreal and tundra ecosystems.”

They neglect to mention that the longer growing season with plants having more CO2 also means plants are more efficient with the water as their water transpiration decreases.

Someone’s got to eat all the extra food you can grow in a longer growing season. Longer growing seasons will increase obesity and diabetes. Global warming bad.

I hope that it is not entirely off topic to draw attention to the ENSO meter which seems to be continuing to fall.
Does this mean a LaNina in prospect?
If so what will the effects be , and I have to admit I succumbed to Wiki:
For us in the UK it seems the major effect will be an increase in Atlantic hurricanes which inevitably ends up as heavy rain storms over Britain at the end of their easterly track. Another typical summer then , just slightly colder and wetter.
Over Canada if it persists into winter it means , apparently, a colder , snowier winter. If this coincides as seems likely with a green obsessed new president in the US refusing exports of certain fuels (assuming Canada needs them) then canadians may be short of fuel – but there are plenty of trees of course.
I was a bit surprised that on the subject of climate change and ENSO the Wiki article was relatively neutral:

-“The recent discovery of ENSO Modoki (ie “similar but different”) has some scientists believing it to be linked to global warming.[42] However, comprehensive satellite data go back only to 1979. Generally, there is no scientific consensus on how/if climate change may affect ENSO.[43] “-

One thing puzzled me however about the effects in SE Asia : they give an example of its effect:
-” In March 2008, La Niña caused a drop in sea surface temperatures over Southeast Asia by 2 °C (36 °F). It also caused heavy rains over Malaysia, the Philippines, and Indonesia.[26]”-
I thought increased precipitation was associated with an increase , not decrease , in SST.

“…climate model’s dismal track record of prediction failure, …” What are you talking about? They have a sterling record of prediction failure.

The area forecast for my area is 7 more days of rain which started on Sunday evening. Then 3 days of clouds finishes the 10 day forecast. Quite a change from years past for this time of year.

I live in southern Ontario, about an hour’s drive from McMaster U. I almost fell off my chair when I read this latest research. Our spring this year has been, for the most part, unusually cool and wet. Yesterday, I had to sweep about 2 inches of heavy, wet snow off the car. Last night in toronto, the temperature fell to a low of minus 3 degrees celsius – beating the record for that day, set in 1939. PLEASE BRING ON WARMING.

The Alarmist have a continually expanded list of tasks to combat the increasing number of benefits to seen coming from warmer weather. People generally welcome warmer weather and also plants welcome and like increased CO2. Increased food production and reduced tempests are a spin-off that Alarmists must deal with. The adjustment of data in search of catastrophe is becoming a severe task for them.

More food means more people.

That has to be bad…

and well it may be, at least partly so. More people possibly means more crazy thinking of the sort seen in the quoted article.

I’ll take the increased chance of Australian bushfires due to slightly higher temperatures, as the offset is probably more rain (in my case – welcome summer rain) reducing that probability as well as making it easier to farm.

A gradually warming earth (0.05C/decade since 1850/0.14C/decade since 1979) and higher CO2 levels have been a huge boon for all life on earth because: growing seasons are longer, less crop frost loss, higher CO2 levels reduce plant water requirements, massive increase in global greening, huge expansion of arable land in northern latitudes, much higher crop yields, lower Winter heating costs, more plankton, expanded tree lines, and fewer exposure deaths, etc.,

Leftists predicting global warming is an existential threat is utterly insane..

BTW, it’s likely we’ll soon enter a 30-year global cooling cycle when the PDO/AMO enter their respective 30-year cool cycles and a 50-year Grand Solar Minimum plays out.

There is a huge 4.5 million KM^2 cold blob developing along the Gulf Stream in the North Atlantic, and a strong La Niña cycle is developing:

We are in that cooling cycle.

WHAT “longer growing seasons? In the Midwest we’re getting October snowstorms and May snowstorms. We’re getting hit by frost in May when we’re not getting snow.
