But for the Norway and Sampdoria star, there’s one game that he and humanity cannot afford to lose.
The climate emergency is fast approaching extra-time, but can he and the football community be the vehicle to deliver a game-changing moment?
Two recurring words come to light when speaking with the mild-mannered midfielder: purpose and potential.
For Thorsby, it’s football’s marriage with the natural world that provides the drive behind both impulses.
Growing up, the fair-haired Norwegian was conscious of “all the possibilities that nature gave [him]” with the very game he loved itself dependent on the living, breathing ecosystem around it.
His awareness of the changing environment was brought into sharp focus when leaving his homeland as an 18-year-old to sign for Dutch top-flight outfit Heerenveen.
It was a moment which left him questioning both the world around him and his very purpose as a footballer — but also one that would come to define who he is today.
“When I started speaking about [climate] six, seven years ago, approximately […] it was very hard getting through to my colleagues, other players and also the clubs,” he admits.
“Being a professional athlete and football player is a very personal project. It’s an egoistic project.
“I felt: ‘Is this the right way or use of my time? […] Does it give anything back to society?'”
After consultations with his parents, a decision was reached.
“The best thing I can do is become as good as possible in football and keep on using my voice and spreading the word,” he says with a smile.
The 3.5 billion-strong football community
How then to rally the wider football community to regain mankind’s balance with nature?
The mission statement is one of engaging and empowering players and clubs around the world to take on environmental initiatives and spread the word to the game’s 3.5 billion-strong global community.
“It was the reaction by me being an engaged individual in the football world that I was missing,” he says of his motives.
And the mechanism to enable this scaling up? Social media.
Quite simply, as Thorsby puts it: “If we can get the word out to three-and-a-half billion people, that could make a huge difference.”
In practice, Thorsby hopes to launch a sustainability league in Norway next year with the goal of establishing coaching programs to help “greenify the football community.”
It’s a project which he hopes will sow the seed for the football family to make an impression on the wider community.
“The argument that politics and football is not related is no longer valid,” he says.
“We need to find solutions across borders, across culture, across religion — all these things that football can bridge.
“The industry is realizing this wave is coming — there’s no turning back.”
Changing mindsets
Heatwaves and heat stroke will threaten the health of both players and fans alike.
With the consequences of inaction becoming ever more tangible, Thorsby is convinced matters of sustainability and climate are growing larger and larger in the minds of the football community.
“Fans are starting to care […] and they want to see their clubs care about it, and they want the players to play for the clubs to care about it. It’s kind of a circle we have to make happen,” he explains.
It was a reaction the Norwegian says was “pure [and] that’s real.”
And with the distance between the game’s power brokers and fans seemingly the widest it has ever been, for Thorsby, it’s the players who “are the key elements in the football industry.”
“If you’re a player today, you would never play for a racist club, no matter what money was involved,” he explains.
“The same thing I think will happen when it comes to climate. You will see a shift [with] players choosing to play for clubs that actually take this social responsibility.
“That can also create a bigger value for football. I think it’s just a matter of time before it starts to happen.”
An imperfect system
It’s why the sharing of existing knowledge is instrumental to equalizing what he calls “an imperfect system.”
The world, as Thorsby sees it, is split between the informed and the uninformed with the task now being to bridge that divide.
“We’re in the very difficult phase because nothing is sustainable because we don’t have a solution,” he says candidly.
“You can’t blame somebody who is not aware and not taking the right decisions. The people who are informed, [they] have to now start to take responsibility.
“The people who is not [informed] we have to make them aware, so they can start to make concrete action.”
While Thorsby acknowledges that, at least in the short term, the game largely remains without practical tangible solutions to take on the climate emergency, we can still all play our part.
He sets out three basic principles: first, assess how we can cut down our own footprint; second, educate ourselves and influence others on environmentalism; and third and perhaps most importantly, use our voting powers to elect environmentally conscious representatives.
Small steps but with the collective potential for a bigger change.
‘I wanted the 1.5 degree shirt’
Perhaps the most important step on this journey of change is to create awareness.
He sings the praises of Swedish climate activist Greta Thunberg — whom he regularly retweets — describing her as “unhuman.”
“She’s the perfect example we’re all trying to look up to and we need that role model.”
And it’s in that spirit that the skilled midfield operator has made a symbolic and significant statement this season.
“Before every season we have the ability to change the [shirt] number. And I was thinking ‘What can I do?’,” he explains.
“I saw the No. 2 shirt and I was thinking that can symbolize the primary objective in the Paris Agreement on limiting global warming to above two degrees.”
Thorsby, who joined Serie A club Sampdoria in 2019, had previously worn the No.18 shirt.
“Of course, I wanted to have the 1.5 [degree] shirt — but I mean, that’s quite difficult on the football shirt to have 1.5! So I had to stick with the two,” he laughs.
“I will keep on playing with the No. 2 until we see that we reach that goal.”
A moral obligation
Under countries’ current targets, the world will continue to warm to 2.7 degrees, according to UNEP.
It’s little surprise, therefore, that the forthcoming COP26 summit in Glasgow is being viewed as a once-in-a-lifetime opportunity to hit the reset button on the climate crisis.
“We have to be hard on ourselves and say that we haven’t done much things right the last 30 years,” he admits.
“We’ve been doing things not in denial but without the right information.
“Now, we have the right information, and now, we have the moral obligation to do something with it.”
And for all the talk of urgency, clear, real-world actions are now needed.
So how long does he believe the world has to turn the tide?
“The next 20 years will be decisive of where we go and probably also what the world will look like in the next 1,000 years.”
The reality is stark, and the outlook unpredictable, but it’s now up to us to collectively take Thorsby’s ball and run with it.
