Since 1880, the Earth’s average surface temperature has risen by 0.07°C (0.13°F) every decade. That number alone may seem negligible, but over time, it adds up.

In addition, the rate of temperature change has grown significantly more dramatic over time—more than doubling to 0.18°C (0.32°F) since 1981. As a result of this global warming process, environmental crises have become the most prominent risks of our time.

In this global temperature graph, climate data scientist Neil R. Kaye breaks down how monthly average temperatures have changed over nearly 170 years. Temperature values have been benchmarked against pre-industrial averages (1850–1900).

What is Causing Global Warming?

The data visualization can be thought of in two halves, each reflecting significant trigger points in global warming trends:

  • 1851-1935
    Overlaps with the Second Industrial Revolution
    Low-High range in global temperature increase: -0.4°C to +0.6°C
  • 1936-2020
    Overlaps with the Third Industrial Revolution
    Low-High range in global temperature increase: +0.6°C to +1.5°C and up

The global temperature graph makes it clear that for several years now, average surface temperatures have consistently surpassed 1.5°C above their pre-industrial values. Let’s dig into these time periods a bit more closely to uncover more context around this phenomenon.

Industrial Revolutions and Advances, 1851–1935

An obvious, early anomaly on the visual worth exploring occurs between 1877–1878. During this time, the world experienced numerous unprecedented climate events, from a strong El Niño to widespread droughts. The resulting Great Famine caused the deaths of between 19–50 million people, even surpassing some of the deadliest pandemics in history.

In the first five rows of the global temperature graph, several economies progressed into the Second Industrial Revolution (~1870–1914), followed by World War I (1914-1918). Overall, there was a focus on steel production and mass-produced consumer goods over these 80+ years.

Although these technological advances brought immense improvements, they came at the cost of burning fossil fuels—releasing significant amounts of carbon dioxide and other greenhouse gases. It would take several more decades before scientists realized the full extent of their accumulation in the atmosphere, and their resulting relation to global warming.

The Modern World In the Red Zone, 1936–2020

The second half of the global temperature graph is marked by World War II (1939-1945) and its aftermath. As the dust settled, nations began to build themselves back up, and things really kicked into hyperdrive with the Third Industrial Revolution.

As globalization and trade progressed following the 1950s, people and goods began moving around more than ever before. In addition, population growth peaked at 2.1% per year between 1965 and 1970. Industrialization patterns began to intensify further to meet the demands of a rising global population and our modern world.

The Importance of Historical Temperature Trends

The history of human development is intricately linked with global warming. While part of the rise in Earth’s surface temperature can be attributed to natural patterns of climate change, these historical trends shed some light on how much human activities are behind the rapid increase in global average temperatures in the last 85 years.

The following video from Reddit user bgregory98, which leverages an extensive data set published in Nature Geoscience provides a more dramatic demonstration. It looks at the escalation of global temperatures over two thousand years. In this expansive time frame, eight of the top ten hottest years on record have occurred in the last decade alone.

Global warming and climate change are some of the most pressing megatrends shaping our future. However, with the U.S. rejoining the Paris Climate Agreement, and the reduction of global carbon emissions highlighted as a key item at the World Economic Forum’s Davos Summit 2021, promising steps are being taken.

The Biggest Carbon Emitters, By Sector

It’s no secret that greenhouse gas emissions need to decrease drastically in order to fight the effects of climate change.

As countries across the globe ramp up efforts to reduce global warming, every industry needs to do its part. So who’s lagging and who’s leading?

Although often less discussed, the manufacturing and construction sector is a large contributor to global greenhouse gas emissions.

The above graphic from Northstar Clean Technologies takes a look at the biggest contributors by sector in relation to greenhouse gas emissions.

Breakdown Of Emissions

The manufacturing and construction sector is a growing one, and as population and infrastructure expand, it’s vital that we take all actionable paths to reduce emissions.

Manufacturing and construction contributed to 6.3 billion tonnes of global greenhouse gas emissions in 2019. Let’s look at the breakdown of greenhouse gas emissions by sector over the years from Our World In Data.

In 2019 electricity and heat were the biggest carbon emitters, while transport came in second place.

Manufacturing and construction overtook the agriculture sector in 2007 to become the third largest contributor to global greenhouse gas emissions.

Building a Solution

One solution to reducing the impact of the manufacturing and construction sector is to repurpose materials. This reduces emissions and waste while also being both energy and cost-efficient.

Take a material like asphalt shingles as an example. This product is found on the roofs of approximately 75% of single-family detached homes in the U.S. and Canada.

In 2018, 86% of total asphalt shingles waste was dumped in landfills where they do not decompose or biodegrade. Reusing and recycling existing materials like asphalt shingles is a vital step in reducing greenhouse gas emissions in the industry.

Northstar Clean Technologies repurposes the three primary components of asphalt shingles which are then recycled back into the market.

By reprocessing asphalt shingles into three primary components, Northstar’s clean technology has been shown to reduce CO₂ emissions by 60% compared to virgin production of liquid asphalt.

Mapped: Carbon Dioxide Emissions Around the World

Mapped: Carbon Dioxide Emissions Around the World

According to Our World in Data, the global population emits about 34 billion tonnes of carbon dioxide (CO₂) each year.

Where does all this CO₂ come from? This graphic by Adam Symington maps out carbon emissions around the world, using 2018 data from the European Commission that tracks tonnes of CO₂ per 0.1 degree grid (roughly 11 square kilometers).

This type of visualization allows us to clearly see not just population centers, but flight paths, shipping lanes, and high production areas. Let’s take a closer look at some of these concentrated (and brightly lit) regions on the map.

China, India, and the Indian Ocean

As the two most populated countries and economic forces, China and India are both significant emitters of CO₂. China in particular accounts for about 27% of global CO₂ emissions.

And looking at the oceans, we see how much shipping adds to emissions, with many shipping lanes east of China clearly outlined as well as the major Indian Ocean lane between the Strait of Malacca and the Suez Canal.

The United States and Central America

The United States is one of the world’s biggest carbon emitters. While other countries like Qatar and Saudi Arabia technically have higher emissions per capita, their overall emissions are relatively low due to smaller populations.

Across the U.S., the most brightly lit areas are major population centers like the Boston-Washington corridor, the Bay Area, and the Great Lakes. But also lit up are many of the interconnecting highways linking all these population centers, even in the less-populated middle of the country.

With so much traffic in and out of the U.S., the oceans become a murky mix of shipping and flight paths. To the south, very clearly visible is the major concentration of people around Mexico City and the traffic flowing through the Panama Canal.

South America’s Network of Emissions

Like the other regions, some of South America’s most populated areas are also the biggest emitters, such as São Paulo and Rio in Brazil and Buenos Aires in Argentina. This map also highlights the continent’s rough terrain, with most of the population and highway emissions limited to the coasts.

However, the cities aren’t the only big emitters in the region. There are clear lines intersecting the Amazon forest in many sections where cities and roads were constructed, including the economic hub city of Manaus along the Amazon River. Likewise, the oceans have many major shipping lanes highlighted, particularly East of Brazil.

Europe and North Africa

Germany is one of Europe’s biggest carbon emitters—in 2021, the country generated almost 644 million tonnes of CO₂.

Also making an impression are Italy (which is the second-highest CO₂ emitter after Germany) and the UK, as well the significant amount of trade along the English Channel.

Compared to the intricate network of cities, towns, and bustling highways spanning Europe, across the Mediterranean are far clearer and simpler lines of activity in Northern Africa. Two major exceptions are in the Middle-East, where Egypt’s Nile River and Suez Canal are massively lit up, as well as Israel on the east of the sea.

But a more significant (albeit murkier) picture is drawn by the massive amounts of shipping and flight paths illuminating the Atlantic and Mediterranean at large.

Net Zero by 2050

To mitigate the negative effects of climate change, countries around the world have made commitments to reach net-zero emissions.

Imagining the global map of emissions with these commitments in action requires a complete transformation of energy production, consumption habits, transportation infrastructure, and more. And even then, a future generated map wouldn’t be fully dark, as “net-zero” is not equivalent to zero emissions but a balance of emissions and removal.

How might this map of global emissions look in the near and distant future? And what other interesting insights can you generate by browsing the world this way?
