Environmental pessimism despite the facts

Alexander Hammond refutes one of the many, many articles preaching global environmental doom and disaster:

Last week, The Scotsman published an article by the journalist Anastasiia Zagoruichyk. In the piece, Zagoruichyk claims that thanks to climate change, fires, and deforestation in her native Ukraine, her children won’t get to experience childhood joys like “walking in the autumn forest, picking mushrooms and breathing fresh air.”

Forest coverage in Ukraine is, admittedly, a niche topic, but alarmism about the future of our forests and our children is unfortunately widespread. Indeed, it was not long ago that Extinction Rebellion founder Roger Hallam confidently declared that due to deforestation and other environmental damage, “our children are going to die in the next 10-20 years.” Thankfully for humanity, these far-fetched claims are not based in reality.

Contrary to what Zagoruichyk would have you believe, forest coverage in Ukraine has increased drastically in recent years. Between 1992 (the oldest data available) and 2020, the share of land in Ukraine covered by forest increased from 16.1 percent to 16.7 percent. While a 0.6 percentage point increase might seem like a small amount, this equates to an additional 3,622 square kilometers of forest – a land area roughly 1.5 times larger than the country of Georgia.

Globally, the world does continue to lose forest area. However, according to the United Nation’s Food and Agriculture Organisation (FAO), the rate of deforestation between 2010-2020 was 40 percent lower than in 1990-2000. At this rate, even without additional promises from world leaders at COP, the global deforestation rate will likely hit zero. Indeed, over the last 30 years, net afforestation has occurred in Europe (including Russia), North America, Oceania, and Asia.

The world’s two poorest regions, South America and Africa, are also the only ones that continue to experience net deforestation. This is no coincidence; many environmental scientists and commentators suggest that economic and ecological well-being are intimately related. According to one hypothesis, called the Environmental Kuznets Curve, a region’s environment worsens in tandem with economic growth but only until a certain income per capita is reached. At that point, people can afford to protect the environment, and ecosystems flourish. This environmental recovery has occurred across Europe and North America and is currently happening in China, Russia, India, and Vietnam.

Therefore, as South America and Africa continue to become richer, we can expect their rate of forest loss to slow and eventually reverse. Given this good news, why is there so much pessimism about the future of our forests? Zagoruichyk’s article offers some answers.

Earlier this month, Michael Shellenberger also had good-but-ignored environmental news to report in UnHerd:

No global problem has ever been more exaggerated than climate change. As it has gone from being an obscure scientific question to a theme in popular culture, we’ve lost all sense of perspective.

Here are the facts: in Europe, emissions in 2020 were 26% below 1990 levels. In the United States, emissions in 2020 were 22% below 2005 levels. Emissions are likely to start declining, too, in developing nations, including China and India, within the next decade. Most nations’ emissions will be bigger this year than last, due to post-Covid economic growth. But global emissions are still likely to peak within the next decade.

And the result will be a much smaller increase in global average temperatures than almost anyone predicted just five years ago. The best science now predicts that temperatures are likely to rise just 2.5-3°C above pre-industrial levels. It’s not ideal, but it’s a far cry from the hysterical and apocalyptic predictions of 6°C, made just a decade ago. A 3°C increase is hardly an existential threat to humanity.

Not that you’d know it, if you had half an eye on the headlines this summer. The floods, fires and heatwaves that plagued the world were, for many observers, proof that the impacts of climate change have already become catastrophic. In Europe, more than 150 people died in flooding. In the United States, wildfire season started earlier and lasted longer, razing hundreds of thousands of acres. Around the world, hundreds died from heatwaves.

But again, it’s worth reminding ourselves of the facts: there has been a 92% decline in the per decade death toll from natural disasters since its peak in the 1920s. In that decade, 5.4 million people died from natural disasters. In the 2010s, just 0.4 million did. Globally, the five-year period ending in 2020 had the fewest natural disaster deaths of any five-year period since 1900. And this decline occurred during a period when the global population nearly quadrupled — and temperatures rose more than 1°C degree centigrade above pre-industrial levels.
