What Will the World Look Like in the 2020s?

2024 – Over 120,000 People Left to Die

Extreme heatwaves have resulted in some 120,000 deaths.¹ France has been most affected, where some 40,000 people have lost their lives.² Doctors blame the deaths on a combination of extreme temperatures and a lack of ventilation in European buildings.³ They explain that the human body is usually capable of dealing with extreme heat as long as it has sufficient time to recover.⁴ However, with many buildings unable to cool down sufficiently overnight,⁵ body temperatures have continued to rise. This has led to the body temperatures of many Europeans rising to more than 41.5°C, at which point widespread damage occurs to vital organs, including the brain, unless immediate medical attention is obtained.⁶ Worryingly, the Global Health Organisation warns that body temperatures exceeding 41.5°C are going to become commonplace over the course of the next two decades.⁷ Furthermore, the organisation states that we should expect the number of lives lost to increase from tens of thousands to hundreds of thousands by the end of the century if human-made emissions of greenhouse gases continue to increase.⁸

2025 – Carbon Emissions Rise by 40%

In a statement today, the UN announced that human-made greenhouse gas emissions have increased by 41% since the turn of the century.⁹ This means that humans are responsible for pumping the equivalent of 52.2 billion tonnes of carbon dioxide into the atmosphere each year.¹⁰ This has resulted in the amount of carbon dioxide equivalent in the atmosphere rising to a record high of 455 ppm.¹¹

2026 – Half the World’s Coral Declared Dead

Scientists have released a report revealing that more than 50% of the world's coral has now died.¹² They go on to explain the consequences of this, as, despite occupying only a tiny fraction of the ocean's surface, coral reefs are home to around a quarter of all marine species.¹³ Scientists explain that the coral losses are the result of sea temperatures rising above 30°C, at which point the water becomes too hot for the coral to survive.¹⁴ The report adds, even if we stop all emissions now, further rises in sea temperatures are now unavoidable leading to the loss of nearly all the ocean's coral by as early as 2045.¹⁵

2027 – Dust Storms Ravage the States

The USA is in a state of emergency as vast swathes of the country are left devastated by the biggest drought in nearly 1,000 years.¹⁶ Monstrous dust storms span from Florida to Dakota, with water shortages now gripping 80% of the nation.¹⁷ Over seven states have been struck so far, with fifteen more expected by 2050.¹⁸ Government scientists report that the last comparable event occurred in the middle ages when freak heatwaves left nearly half of America beneath the sands.¹⁹ Sadly, if temperatures continue to rise, it is only a matter of time before many states become completely uninhabitable.²⁰ Emergency food imports have been organised as crop production has been decimated.²¹ In total, some 5.5 million people have been forced to relocate with more than 33 million expected to relocate by the middle of the century.²² Additionally, agricultural losses alone are expected to top $2 trillion by 2050, bringing even more damage to the now fragile American economy.²³

2028 – The End of the North Pole

One of the Last Sightings of a Polar Bear in the Wild

Climate change is now undeniably confirmed as the North Pole has become ice-free for the first time in more than 100,000 years.²⁴ Only thirty years ago, as much as seven million square kilometres of the North Pole was covered in ice.²⁵ Now, all that can be seen are thousands of kilometres of open ocean. Scientists explain that the rapid melting of the ice was inevitable once pockets of the ocean became exposed to the sun's light.²⁶ This is because ice absorbs around 40% of the sunlight that strikes its surface, whereas seawater absorbs some 94%.²⁷ As a result, the temperatures in the Arctic have risen roughly twice the average rate.²⁸ This has led to unprecedented rates of arctic melting with as much as 400,000 square kilometres disappearing in a single season.²⁹ Unfortunately, such rapid melting has proved to be too much for polar bears which are now doomed to extinction.³⁰ The loss of sea ice has also provided access to even more fossil fuels,³¹ which if used, will further increase the rate at which the planet warms. Scientists gloomily state that the melting of the ice cap marks the beginning of a new era for humankind – the era of climate change.

2029 – The Deserts Are Growing

The planet is drying up as the world's deserts continue to expand.³² Scientists estimate that an additional six million square kilometres have emerged within the past decade alone.³³ That is an area roughly twice the size of India.³⁴ This is just the beginning though, with the world's desert area predicted to cover some 40 million square kilometres by the end of the century.³⁵ That is an increase of 15 million square kilometres.³⁶ Worst hit is Africa where some 500 million people are already suffering from chronic malnutrition.³⁷
