UN report says nature is in worst shape in human history

Published

9 minute read

Nature is in more trouble now than at any other time in human history, with extinction looming over 1 million species of plants and animals, scientists said Monday in the United Nations’ first comprehensive report on biodiversity.

It’s all because of humans, but it’s not too late to fix the problem, the report said.

Species loss is accelerating to a rate tens or hundreds of times faster than in the past, the report said. More than half a million species on land “have insufficient habitat for long-term survival” and are likely to go extinct, many within decades, unless their habitats are restored. The oceans are not any better off.

“Humanity unwittingly is attempting to throttle the living planet and humanity’s own future,” said George Mason University biologist Thomas Lovejoy, who has been called the godfather of biodiversity for his research. He was not part of the report.

“The biological diversity of this planet has been really hammered, and this is really our last chance to address all of that,” Lovejoy said.

Conservation scientists from around the world convened in Paris to issue the report, which exceeded 1,000 pages. The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) included more than 450 researchers who used 15,000 scientific and government reports. The report’s summary had to be approved by representatives of all 109 nations.

Some nations hit harder by the losses, like small island countries, wanted more in the report. Others, such as the United States, were cautious in the language they sought, but they agreed “we’re in trouble,” said Rebecca Shaw, chief scientist for the World Wildlife Fund, who observed the final negotiations.

“This is the strongest call we’ve seen for reversing the trends on the loss of nature,” Shaw said.

The findings are not just about saving plants and animals, but about preserving a world that’s becoming harder for humans to live in, said Robert Watson, a former top NASA and British scientist who headed the report.

“We are indeed threatening the potential food security, water security, human health and social fabric” of humanity, Watson told The Associated Press. He said the poor in less developed countries bear the greatest burden.

The report’s 39-page summary highlighted five ways people are reducing biodiversity:

— Turning forests, grasslands and other areas into farms, cities and other developments. The habitat loss leaves plants and animals homeless. About three-quarters of Earth’s land, two-thirds of its oceans and 85% of crucial wetlands have been severely altered or lost, making it harder for species to survive, the report said.

— Overfishing the world’s oceans. A third of the world’s fish stocks are overfished.

— Permitting climate change from the burning of fossil fuels to make it too hot, wet or dry for some species to survive. Almost half of the world’s land mammals — not including bats — and nearly a quarter of the birds have already had their habitats hit hard by global warming.

— Polluting land and water. Every year, 300 to 400 million tons of heavy metals, solvents and toxic sludge are dumped into the world’s waters.

— Allowing invasive species to crowd out native plants and animals. The number of invasive alien species per country has risen 70% since 1970, with one species of bacteria threatening nearly 400 amphibian species.

Fighting climate change and saving species are equally important, the report said, and working on both environmental problems should go hand in hand. Both problems exacerbate each other because a warmer world means fewer species, and a less biodiverse world means fewer trees and plants to remove heat-trapping carbon dioxide from the air, Lovejoy said.

The world’s coral reefs are a perfect example of where climate change and species loss intersect. If the world warms another 0.9 degrees (0.5 degrees Celsius), which other reports say is likely, coral reefs will probably dwindle by 70% to 90%, the report said. At 1.8 degrees (1 degree Celsius), the report said, 99% of the world’s coral will be in trouble.

“Business as usual is a disaster,” Watson said.

At least 680 species with backbones have already gone extinct since 1600. The report said 559 domesticated breeds of mammals used for food have disappeared. More than 40% of the world’s amphibian species, more than one-third of the marine mammals and nearly one-third of sharks and fish are threatened with extinction.

The report relies heavily on research by the International Union for the Conservation of Nature, or IUCN, which is composed of biologists who maintain a list of threatened species.

The IUCN calculated in March that 27,159 species are threatened, endangered or extinct in the wild out of nearly 100,000 species biologists examined in depth. That includes 1,223 mammal species, 1,492 bird species and 2,341 fish species. Nearly half the threatened species are plants.

Scientists have only examined a small fraction of the estimated 8 million species on Earth.

The report comes up with 1 million species in trouble by extrapolating the IUCN’s 25% threatened rate to the rest of the world’s species and using a lower rate for the estimated 5.5 million species of insects, Watson said.

Outside scientists, such as Lovejoy and others, said that’s a reasonable assessment.

The report gives only a generic “within decades” time frame for species loss because it is dependent on many variables, including taking the problem seriously, which can reduce the severity of the projections, Watson said.

“We’re in the middle of the sixth great extinction crisis, but it’s happening in slow motion,” said Conservation International and University of California Santa Barbara ecologist Lee Hannah, who was not part of the report.

Five times in the past, Earth has undergone mass extinctions where much of life on Earth blinked out, like the one that killed the dinosaurs. Watson said the report was careful not to call what’s going on now as a sixth big die-off because current levels don’t come close to the 75% level in past mass extinctions.

The report goes beyond species. Of the 18 measured ways nature helps humans, the report said 14 are declining, with food and energy production noticeable exceptions. The report found downward trends in nature’s ability to provide clean air and water, good soil and other essentials.

Habitat loss is one of the biggest threats, and it’s happening worldwide, Watson said. The report projects 15.5 million miles (25 million kilometres) of new roads will be paved over nature between now and 2050, most in the developing world.

Many of the worst effects can be prevented by changing the way we grow food, produce energy, deal with climate change and dispose of waste, the report said. That involves concerted action by governments, companies and people.

Individuals can help with simple changes to the way they eat and use energy, said the co-chairman of the report, ecological scientist Josef Settele of the Helmholtz Center for Environmental Research in Germany. That doesn’t mean becoming a vegetarian or vegan, but balancing meat, vegetables and fruit, and walking and biking more, Watson said.

“We can actually feed all the coming billions of people without destroying another inch of nature,” Lovejoy said. Much of that can be done by eliminating food waste and being more efficient, he said.

Net Zero goal is a fundamental flaw in the Ottawa-Alberta MOU

Published on

From the Fraser Institute 

By Jason Clemens and Elmira Aliakbari

The challenge of GHG emissions in 2050 is not in the industrial world but rather in the developing world, where there is still significant basic energy consumption using timber and biomass.

The new Memorandum of Understanding (MOU) between the federal and Alberta governments lays the groundwork for substantial energy projects and infrastructure development over the next two-and-a-half decades. It is by all accounts a step forward, though, there’s debate about how large and meaningful that step actually is. There is, however, a fundamental flaw in the foundation of the agreement: it’s commitment to net zero in Canada by 2050.

The first point of agreement in the MOU on the first page of text states: “Canada and Alberta remain committed to achieving net zero greenhouse gas emissions by 2050.” In practice, it’s incredibly difficult to offset emissions with tree planting or other projects that reduce “net” emissions, so the effect of committing to “net zero” by 2050 means that both governments agree that Canada should produce very close to zero actual greenhouse gas (GHG) emissions. Consider the massive changes in energy production, home heating, transportation and agriculture that would be needed to achieve this goal.

So, what’s wrong with Canada’s net zero 2050 and the larger United Nations’ global goal for the same?

Let’s first understand the global context of GHG reductions based on a recent study by internationally-recognized scholar Vaclav Smil. Two key insights from the study. First, despite trillions being spent plus international agreements and regulatory measures starting back in 1997 with the original Kyoto agreement, global fossil fuel consumption between then and 2023 increased by 55 per cent.

Second, fossil fuels as a share of total global energy declined from 86 per cent in 1997 to 82 per cent in 2022, again, despite trillions of dollars in spending plus regulatory requirements to force a transition away from fossil fuels to zero emission energies. The idea that globally we can achieve zero emissions over the next two-and-a-half decades is pure fantasy. Even if there is an historic technological breakthrough, it will take decades to actually transition to a new energy source(s).

Let’s now understand the Canada-specific context. A recent study examined all the measures introduced over the last decade as part of the national plan to reduce emissions to achieve net zero by 2050. The study concluded that significant economic costs would be imposed on Canadians by these measures: inflation-adjusted GDP would be 7 per cent lower, income per worker would be more than $8,000 lower and approximately 250,000 jobs would be lost. Moreover, these costs would not get Canada to net zero. The study concluded that only 70 per cent of the net zero emissions goal would be achieved despite these significant costs, which means even greater costs would be imposed on Canadians to fully achieve net zero.

It’s important to return to a global picture to fully understand why net zero makes no sense for Canada within a worldwide context. Using projections from the International Energy Agency (IEA) in its latest World Energy Outlook, the current expectation is that in 2050, advanced countries including Canada and the other G7 countries will represent less than 25 per cent of global emissions. The developing world, which includes China, India, the entirety of Africa and much of South America, is estimated to represent at least 70 per cent of global emissions in 2050.

Simply put, the challenge of GHG emissions in 2050 is not in the industrial world but rather in the developing world, where there is still significant basic energy consumption using timber and biomass. A globally-coordinated effort, which is really what the U.N. should be doing rather than fantasizing about net zero, would see industrial countries like Canada that are capable of increasing their energy production exporting more to these developing countries so that high-emitting energy sources are replaced by lower-emitting energy sources. This would actually reduce global GHGs while simultaneously stimulating economic growth.

Consider a recent study that calculated the implications of doubling natural gas production in Canada and exporting it to China to replace coal-fired power. The conclusion was that there would be a massive reduction in global GHGs equivalent to almost 90 per cent of Canada’s total annual emissions. In these types of substitution arrangements, the GHGs would increase in energy-producing countries like Canada but global GHGs would be reduced, which is the ultimate goal of not only the U.N. but also the Carney and Smith governments as per the MOU.

Finally, the agreement ignores a basic law of economics. The first lesson in the very first class of any economics program is that resources are limited. At any given point in time, we only have so much labour, raw materials, time, etc. In other words, when we choose to do one project, the real cost is foregoing the other projects that could have been undertaken. Economics is mostly about trying to understand how to maximize the use of limited resources.

The MOU requires massive, literally hundreds of billions of dollars to be used to create nuclear power, other zero-emitting power sources and transmission systems all in the name of being able to produce low or even zero-emitting oil and gas while also moving to towards net zero.

These resources cannot be used for other purposes and it’s impossible to imagine what alternative companies or industries would have been invested in. What we do know is that workers, entrepreneurs, businessowners and investors are not making these decisions. Rather, politicians and bureaucrats in Ottawa and Edmonton are making these decisions but they won’t pay any price if they’re wrong. Canadians pay the price. Just consider the financial fiasco unfolding now with Ottawa, Ontario and Quebec’s subsidies (i.e. corporate welfare) for electric vehicle batteries.

Understanding the fundamentally flawed commitment to Canadian net zero rather than understanding a larger global context of GHG emissions lays at the heart of the recent MOU and unfortunately for Canadians will continue to guide flawed and expensive policies. Until we get the net zero policies right, we’re going to continue to spend enormous resources on projects with limited returns, costing all Canadians.

Canada is failing dismally at our climate goals. We’re also ruining our economy.

Published on

From the Fraser Institute

By Annika Segelhorst and Elmira Aliakbari

Short-term climate pledges simply chase deadlines, not results

The annual meeting of the United Nations Conference of the Parties, or COP, which is dedicated to implementing international action on climate change, is now underway in Brazil. Like other signatories to the Paris Agreement, Canada is required to provide a progress update on our pledge to reduce greenhouse gas (GHG) emissions by 40 to 45 per cent below 2005 levels by 2030. After decades of massive government spending and heavy-handed regulations aimed at decarbonizing our economy, we’re far from achieving that goal. It’s time for Canada to move past arbitrary short-term goals and deadlines, and instead focus on more effective ways to support climate objectives.

Since signing the Paris Agreement in 2015, the federal government has introduced dozens of measures intended to reduce Canada’s carbon emissions, including more than $150 billion in “green economy” spending, the national carbon tax, the arbitrary cap on emissions imposed exclusively on the oil and gas sector, stronger energy efficiency requirements for buildings and automobiles, electric vehicle mandates, and stricter methane regulations for the oil and gas industry.

Recent estimates show that achieving the federal government’s target will impose significant costs on Canadians, including 164,000 job losses and a reduction in economic output of 6.2 per cent by 2030 (compared to a scenario where we don’t have these measures in place). For Canadian workers, this means losing $6,700 (each, on average) annually by 2030.

Yet even with all these costly measures, Canada will only achieve 57 per cent of its goal for emissions reductions. Several studies have already confirmed that Canada, despite massive green spending and heavy-handed regulations to decarbonize the economy over the past decade, remains off track to meet its 2030 emission reduction target.

And even if Canada somehow met its costly and stringent emission reduction target, the impact on the Earth’s climate would be minimal. Canada accounts for less than 2 per cent of global emissions, and that share is projected to fall as developing countries consume increasing quantities of energy to support rising living standards. In 2025, according to the International Energy Agency (IEA), emerging and developing economies are driving 80 per cent of the growth in global energy demand. Further, IEA projects that fossil fuels will remain foundational to the global energy mix for decades, especially in developing economies. This means that even if Canada were to aggressively pursue short-term emission reductions and all the economic costs it would imposes on Canadians, the overall climate results would be negligible.

Rather than focusing on arbitrary deadline-contingent pledges to reduce Canadian emissions, we should shift our focus to think about how we can lower global GHG emissions. A recent study showed that doubling Canada’s production of liquefied natural gas and exporting to Asia to displace an equivalent amount of coal could lower global GHG emissions by about 1.7 per cent or about 630 million tonnes of GHG emissions. For reference, that’s the equivalent to nearly 90 per cent of Canada’s annual GHG emissions. This type of approach reflects Canada’s existing strength as an energy producer and would address the fastest-growing sources of emissions, namely developing countries.

As the 2030 deadline grows closer, even top climate advocates are starting to emphasize a more pragmatic approach to climate action. In a recent memo, Bill Gates warned that unfounded climate pessimism “is causing much of the climate community to focus too much on near-term emissions goals, and it’s diverting resources from the most effective things we should be doing to improve life in a warming world.” Even within the federal ministry of Environment and Climate Change, the tone is shifting. Despite the 2030 emissions goal having been a hallmark of Canadian climate policy in recent years, in a recent interview, Minister Julie Dabrusin declined to affirm that the 2030 targets remain feasible.

Instead of scrambling to satisfy short-term national emissions limits, governments in Canada should prioritize strategies that will reduce global emissions where they’re growing the fastest.
