Woolly mammoth extinction blamed on climate change, not human hunting

«This is a stark lesson from history and shows how unpredictable climate change is — once something is lost, there is no going back.»

About 4,000 years ago, the last majestic woolly mammoth roaming Earth vanished, and for decades, scientists believed the colossal ancestors of elephants went extinct because humans hunted them relentlessly. DNA analysis of the animals’ old stomping grounds, however, reveals a different story.

The likelier culprit, researchers now say, was rapid climate change that ultimately wiped out the creatures’ food supply. But besides solving the mystery of the disappearing mammoths, these findings may offer a glimpse into the fates of other species if our present climate crisis isn’t controlled.

«We have shown that climate change, specifically precipitation, directly drives the change in the vegetation — humans had no impact on [the mammoths] at all based on our models,» Yucheng Wang, a zoologist at the University of Cambridge and first author of the paper published Wednesday in the journal Nature, said in a statement.

Co-author Eske Willerslev, a fellow at the University of Cambridge and director of the Lundbeck Foundation GeoGenetics Centre at the University of Copenhagen, added, «This is a stark lesson from history and shows how unpredictable climate change is — once something is lost, there is no going back.»

These gentle beings that dined on grass and flowers lived alongside Neanderthals. While many encounters might have been peaceful, the animals were a hot commodity when it came to making fur coats, musical and artistic instruments and hearty meals. That’s because of their thick, chocolate-colored fur, their sturdy, enormous tusks and their huge size.

They weighed approximately 6 tons and stood about 13 feet (4 meters) tall — as Wang puts it, woolly mammoths could «grow to the height of a double-decker bus.»

«Scientists have argued for 100 years about why mammoths went extinct,» Willerslev said. «Humans have been blamed because the animals had survived for millions of years without climate change killing them off before, but when they lived alongside humans they didn’t last long and we were accused of hunting them to death.»

It makes sense that prehistoric people were suspected to be behind woolly mammoths’ eventual demise instead of climate change. These animals somehow withstood the Ice Age about 12,000 years ago — the fanciful Disney movie Ice Age has some thoughts on that — but the new study’s researchers decided to dig a little deeper.

Over a period of 10 years, Willerslev led a team in dissecting DNA fragments collected from the Arctic soil where mammoths were known to graze. The samples were collected over 20 years and analyzed using a method called DNA shotgun sequencing.

DNA shotgun sequencing is an indirect way to create genetic profiles without requiring a person or animal to physically be there. Instead of collecting genetic information from bones or teeth, the method sequences DNA from traces of urine or discarded cells. Scientists have also used this tool to track the movement of COVID-19 by creating DNA profiles from sewage remnants.

The researchers looking into ancient mammoths discovered populations of the enormous animals — uncovered using the sequencing method — were depleted at a rate consistent with the quick speed of climate change at the time. Willerslev says it was because «as the climate warmed up, trees and wetland plants took over and replaced the mammoth’s grassland habitats.»

«When the climate got wetter and the ice began to melt, it led to the formation of lakes, rivers and marshes,» he said. «The ecosystem changed and the biomass of the vegetation reduced and would not have been able to sustain the herds of mammoths.»

Wang also notes that prehistoric humans would’ve probably spent most of their time hunting animals much smaller and easier to capture than enormous woolly mammoths, suggesting their impact on the animals’ extinction was arguably smaller than intuitively thought.

Another important aspect of the findings, Wang said, is «we have finally been able to prove that it was not just the climate changing that was the problem, but the speed of it that was the final nail in the coffin — they were not able to adapt quickly enough when the landscape dramatically transformed and their food became scarce.»

Such speed is why the researchers naturally drew parallels between what happened back then and what appears to be in store for us now. For instance, our global temperature is rising so quickly that many countries’ former goal of limiting the increase to 1.5 degrees Celsius (2.7 degrees Fahrenheit) is now considered nearly impossible by the UN’s Intergovernmental Panel on Climate Change. That’s unless immediate, drastic measures are taken, they say.

«It shows nothing is guaranteed when it comes to the impact of dramatic changes in the weather,» Willerslav said. «The early humans would have seen the world change beyond all recognition. That could easily happen again, and we cannot take for granted that we will even be around to witness it.»

«The only thing we can predict with any certainty is that the change will be massive.»

Why Are Switch 2 Games So Expensive? Trump’s Tariffs May Not Be Sole Factor

It still comes down to money.

Wednesday’s reveal of the Switch 2 had a lot of buzz from Nintendo surrounding its successor to the Switch. One shocking bit, though, was the high price of its games. There’s a lot of confusion, especially with news of President Donald Trump’s increased tariffs on many trading partners, including Japan.

After the Switch 2 Direct, Nintendo released the full details of the upcoming console and games on its website. The price of Mario Kart World shocked gamers and led to some disdain, as the $80 MSRP was $10 more than what most new games cost today. This led many to wonder if this would be a new normal for game prices due to Trump’s tariffs or if Nintendo was just being greedy. The answer, however, might be something completely different.

Are Nintendo Switch 2 game prices hiking?

To start, some details need to be cleared up. Some people have posted on social media that the price of Nintendo’s Switch 2 games, at least in the US, will be $90. That is incorrect, as of right now.

One X user posted Switch 2 EU prices for Mario Kart World, which start at 80 euros for a digital version and 90 euros for the physical copy. Typically, US and EU games match in price, which caused some to assume that this pricing would be the case for the US.

US retailers, however, already posted their Switch 2 game prices, and Nintendo-published games are listed at $80.

Will Trump’s tariffs cause the Switch 2 to cost more?

As for Trump’s tariffs, that is unlikely to be a driver of this price bump. Tariffs are not applied to digital goods, and when the prices were published, there were no tariffs on Japan. Plus, games are similarly expensive in other countries like Canada and the UK.

With that cleared up, why are Nintendo games on the Switch 2 so expensive? One likely reason is game storage.

The Switch 2 uses what Nintendo calls game-key cards, which are Switch 2 cartridges that don’t have all the game data on the cartridge itself. This helps save on production costs as storage is expensive. The original Switch cartridges went up to 32GB of storage, which doesn’t seem like a lot these days, with some games taking up 100GB or more of storage, but this is for the original Switch. Only a few games, like The Witcher 3, went above 32GB because the graphics for the Switch weren’t on the high end like with a PC, PS5 or Xbox Series console, where a Witcher 3 install size starts at 50GB.

Switch 2 games are going to be bigger in size — there is little doubt about it. CD Projekt Red confirmed it would put its Cyberpunk 2077: Ultimate Edition on one 64GB cartridge, and there will likely be other games to surpass that 64GB. With the max size of the cartridge doubling in size, it adds to the price of the physical card, as not only does storage have to be bigger, but they will need to transfer data faster. That can get more expensive for physical copies, unlike optical discs, which are still the same price whether it has 20GB or 100GB on the disc.

What does all this mean for gamers?

This leads to a dilemma for publishers: Put the entire game on the physical card and sell it at a loss, increase the price of the physical copy with the full game on it or use the game-key card to have a card with minimal storage, requiring gamers to download the entire game.

It appears that Nintendo went with door No. 2. This doesn’t come as much of a surprise, knowing the company. Anyone who wants to save money on games knows that Nintendo will seldom bring the price down of its own games. Mario Kart 8 Deluxe, for example, is 8 years old and is still full price on Nintendo’s website.

According to an industry analysis from Niko Partners, this new pricing could become the new normal in a couple of years when it comes to physical cartridges.

«While there has been some sticker shock regarding the price of games increasing from $60 to $70 or $80, these price points are set to become industry standard over the next two years, especially so for Nintendo first-party games,» Niko Partners said in a statement Wednesday. «One reason for the higher price is the increased cost of the new and faster Game Cards themselves, with higher capacities being more expensive to manufacture than a PS5 Blu-ray disc.»

Nintendo didn’t respond to a request for comment about the higher price of its games.

That said, this doesn’t explain the lower price of Donkey Kong Bananza, which comes out in July; that’s listed on Nintendo’s site for $70. This could mean the game isn’t using a larger storage card, but that can’t be said for sure until the game comes out. It’s unclear how things will change in the future.

Nintendo Switch 2 Pre-orders in US Delayed Due to Trump’s Tariffs

The Switch 2 launch is still happening on June 5, and preorders outside the US seem unchanged.

Nintendo Switch 2 preorders in the US were to start April 9, but it appears those plans have changed due to the new tariffs imposed this week by President Donald Trump. It’s unclear if this means Nintendo will also have to increase the price of the Switch successor, which currently starts at $450.

Nintendo said Friday that it’s delaying Switch 2 preorders in the US, but its June release date is unaffected.

«Pre-orders for Nintendo Switch 2 in the U.S. will not start April 9, 2025 in order to assess the potential impact of tariffs and evolving market conditions,» the company said in a statement. «Nintendo will update timing at a later date. The launch date of June 5, 2025 is unchanged.»

Nintendo didn’t indicate if preorder dates outside the US would change, but Eurogamer reports that preorders are live at various retailers in the UK.

A tariff of 24% has been applied by the US to goods from Japan. Were that rate to be applied directly to the Switch 2’s announced price, it would rise to $558, but it would be up to Nintendo how much of the tariff it will pass on to consumers.

This is a developing story.
