Global Ice Loss

The Briefing

  • Due to global warming, 28 trillion tonnes of ice have melted in just over two decades
  • Over half (58%) of this global ice loss occurred in the Northern Hemisphere

Visualizing Earth’s Global Ice Loss Between 1994-2017

Nearly 70% of the Earth’s freshwater is locked up in glaciers and ice caps, ground ice, and permafrost. However, this ice is melting at an unprecedented rate.

Based on data from a new scientific survey, this visualization reveals that 28 trillion tonnes of Earth’s ice has been lost between 1994 and 2017.

How Much Ice Is Being Lost Exactly?

Figures at such scales can be difficult to wrap our heads around. For the record, one billion tonnes of water is equal to 400,000 Olympic swimming pools.

It’s then a bit easier to comprehend why, when multiplied tens of thousands of times, this much melted ice—specifically, grounded ice—has resulted in global sea levels rising by 34.6mm on average.

Cryosphere categoryIce typeChange (1994-2017)
Arctic sea iceFloating7.6 trillion tonnes
Antarctic ice shelvesGrounded6.5 trillion tonnes
Mountain glaciersGrounded6.1 trillion tonnes
Greenland ice sheetGrounded3.8 trillion tonnes
Antarctic ice sheetGrounded2.5 trillion tonnes
Southern Ocean sea iceFloating0.9 trillion tonnes

Over half (58%) of the ice loss occurred in the Northern Hemisphere, from Arctic sea ice and also grounded ice previously trapped in the Greenland ice sheet.

In fact, the rate of ice loss has risen from 0.8 trillion tonnes to 1.2 trillion tonnes per year, an increase of 57% since the 1990s.

The Impacts of the Ice Meltdown

Rapidly disappearing sea ice has severe impacts on the environment, both in the short and long term:

  • Wildlife habitat loss
  • Coastal erosion
  • Changing ocean currents
  • Extreme temperatures

While rising temperatures are behind most of this historical global ice loss, it’s worth noting that lower levels of ice lead to a positive feedback loop. Less ice means less of the sun’s heat is reflected away from the Earth, instead being absorbed back and further amplifying the global warming effect.

Charting the Continued Rise of Remote Jobs

Remote job postings are up nearly across the board, but a few key industries are have seen a significant shift over the last year.

which industries are embracing remote work

The Briefing

  • Four industries saw massive growth in the proportion of remote-friendly job postings
  • Nearly one-third of new software and IT service jobs are listed as remote / work-from-home

Charting the Continued Rise of Remote Jobs

When the pandemic first took hold in 2020, and many workplaces around the world closed their doors, a grand experiment in work-from-home began.

Today, well over a year after the first lockdown measures were put in place, there are still lingering questions about whether remote work would now become a commonplace option, or whether things would generally return to the status quo in offices around the world.

New data from LinkedIn’s Workforce Report shows that remote work may be here to stay, and could even become the norm in a few key industries.

Broadly speaking, 12% of all Canadian paid job postings on LinkedIn offered remote work in September 2021. Prior to the pandemic, that number sat at just 1.3%.

While this data was specific to Canada, the country’s similarity to the U.S. means that these trends are likely being seen across the border as well.

Which Industries are Embracing Remote Work?

The nature of work can vary broadly by job type—for example, mining is tough to do from one’s living room sofa—so remote jobs were not distributed equally across industries.

Here are the numbers on job postings that were geared towards remote work:

Industry% Remote (Sept 2020)% Remote (Sept 2021)Change (p.p.)
Software & IT Services12.5%30.0%17.5
Media & Communications12.5%21.3%8.8
Wellness & Fitness3.3%21.2%17.9
Healthcare3.2%14.4%11.2
Nonprofit4.6%14.1%9.5
Hardware & Networking2.2%12.9%10.7
Corporate Services5.2%9.5%4.3
Education9.4%8.8%-0.6
Entertainment3.0%7.7%4.7
Finance1.8%6.5%4.7
Consumer Goods2.2%6.0%3.8
Recreation & Travel0.2%3.7%3.5
Manufacturing1.4%3.0%1.6
Energy & Mining1.0%2.7%1.7
Retail0.5%0.7%0.2

Tech and healthcare industries are showing big shifts towards remote work, with the latter being influenced by a number of tech-driven changes, including telemedicine.

Physical distancing measures forced some industries to pivot quickly. Whether virtual fitness and wellness options (e.g. Peloton and Headspace) would remain popular beyond the pandemic was a big question mark, but this jobs data seems to indicate continued digital growth in these industries.

What the Future Holds

Since COVID-19 outbreaks are still underway, the true test for this trend will be whether these numbers hold up a year or two from now. When offices and gyms are reliably open again, will companies dial back the work-from-home options?

Today, hybrid solutions are proving popular amidst worries that fully distributed teams suffer from lower levels of collaboration and communication between colleagues, and that innovation could be stifled by lack of in-person collaboration.

Of course, employees themselves are reporting being more productive and happy at home, with 98% of people wanting the option to work remotely for the rest of their careers.

It’s clear that the culture of work is undergoing an evolution today, and companies and employees will continue to seek the perfect balance of productivity and happiness.

Where does this data come from?

Data Note: LinkedIn analyzed hundreds of thousands of paid remote job postings in Canada posted on LinkedIn between February 2020 and September 21, 2021. A “remote job” is defined as one where either the job poster explicitly labeled it as “remote” or if the job contained keywords like “work from home” in the listing.

Print Has Prevailed: The Staying Power of Physical Books

When e-books hit the mainstream in the early 2000s, many predicted they’d eventually make print books obsolete. So far, that prediction has not come true.

Print Books Have Prevailed

The Briefing

  • Survey data from 10 different countries shows that a majority of people still prefer print books over e-books.
  • 42.5% of respondents purchased at least one print book in 2020—that’s significantly more than the 15.5% who’d bought at least one e-book.
  • Out of the 10 countries surveyed, Germany has the most print book lovers. 58% of German respondents bought a print book in 2020.

The Staying Power of Print Books

E-books are certainly not a new phenomenon. In fact, they’ve been around longer than the internet.

Yet, while the emergence of e-books dates back to the early 1970s, they didn’t hit the mainstream until the 2000s, when big companies began launching their own e-book readers, and digital libraries started to become more accessible to the public.

Around this time, sales for e-books started to soar, and by 2013, e-book sales made up 20% of all books sales in America. Many wondered if this was the end for print books.

But fast forward to 2021, and e-books haven’t made print books obsolete. At least, not yet.

E-book versus Print Book Purchases

A recent poll found that people still favor print books over e-books, at least when it comes to their purchasing behavior.

Of the 10 countries included in the survey, an estimated 42% of people had purchased at least one print book in 2020, while only 15.5% had bought an e-book that same year.

Here’s a look at all 10 countries, and the estimated share of their population who bought physical versus e-books in 2020:

CountryPhysical BooksE-books
🇨🇳 China32.0%24.4%
🇺🇸 United States44.5%22.7%
🇬🇧 United Kingdom48.7%20.0%
🇯🇵 Japan40.1%17.3%
🇰🇷 South Korea34.6%16.8%
🇦🇺 Australia41.2%15.9%
🇪🇸 Spain49.3%14.3%
🇩🇪 Germany58.0%10.4%
🇫🇷 France52.1%7.5%
🇮🇳 India24.5%5.6%
Average42.5%15.5%

China had the highest portion of e-book lovers—an estimated 24.4% of its population purchased an e-book in 2020, which is more than 8 percentage points higher than the average across the whole list.

On the other end of the spectrum, e-books are least popular in India, where an estimated 5.6% of the country’s population purchased an e-book in 2020. Keep in mind, the country has a lower percentage of book purchasers in general.

Why Print Has Prevailed

Why are print books still more popular than e-books? There are many theories. One study suggests that readers retain information better from a print book versus an e-book, while other consumer surveys found that e-books haven’t yet managed to fully simulate the tactile experience of a print book.

However, while e-books might not eradicate print books entirely, the market for digital books is expected to grow in the near future. By 2025, global revenue from e-books could reach $18.4 billion, with 1.2 billion users across the globe.
