Worried about Earth’s future? Well, the outlook is worse than even scientists can grasp

From an Article by Corey J. A. Bradshaw, Daniel T. Blumstein and Paul Ehrlich, The Conversation, January 13, 2021

Anyone with even a passing interest in the global environment knows all is not well. But just how bad is the situation? Our new paper shows the outlook for life on Earth is more dire than is generally understood.

The research published today reviews more than 150 studies to produce a stark summary of the state of the natural world. We outline the likely future trends in biodiversity decline, mass extinction, climate disruption and planetary toxification. We clarify the gravity of the human predicament and provide a timely snapshot of the crises that must be addressed now.

The problems, all tied to human consumption and population growth, will almost certainly worsen over coming decades. The damage will be felt for centuries and threatens the survival of all species, including our own.

Our paper was authored by 17 leading scientists, including those from Flinders University, Stanford University and the University of California, Los Angeles. Our message might not be popular, and indeed is frightening. But scientists must be candid and accurate if humanity is to understand the enormity of the challenges we face.

First, we reviewed the extent to which experts grasp the scale of the threats to the biosphere and its lifeforms, including humanity. Alarmingly, the research shows future environmental conditions will be far more dangerous than experts currently believe.

This is largely because academics tend to specialize in one discipline, which means they’re in many cases unfamiliar with the complex system in which planetary-scale problems—and their potential solutions—exist.

What’s more, positive change can be impeded by governments rejecting or ignoring scientific advice, and ignorance of human behavior by both technical experts and policymakers.

More broadly, the human optimism bias – thinking bad things are more likely to befall others than yourself—means many people underestimate the environmental crisis.

Our research also reviewed the current state of the global environment. While the problems are too numerous to cover in full here, they include:

>> A halving of vegetation biomass since the agricultural revolution around 11,000 years ago. Overall, humans have altered almost two-thirds of Earth’s land surface

>> About 1,300 documented species extinctions over the past 500 years, with many more unrecorded. More broadly, population sizes of animal species have declined by more than two-thirds over the last 50 years, suggesting more extinctions are imminent

>> About 1 million plant and animal species globally threatened with extinction. The combined mass of wild mammals today is less than one-quarter the mass before humans started colonizing the planet. Insects are also disappearing rapidly in many regions

>> Some 85% of the global wetland area lost in 300 years, and more than 65% of the oceans compromised to some extent by humans

>> A halving of live coral cover on reefs in less than 200 years and a decrease in seagrass extent by 10% per decade over the last century. About 40% of kelp forests have declined in abundance, and the number of large predatory fishes is fewer than 30% of that a century ago.

The human population has reached 7.8 billion – double what it was in 1970—and is set to reach about 10 billion by 2050. More people equals more food insecurity, soil degradation, plastic pollution and biodiversity loss.

High population densities make pandemics more likely. They also drive overcrowding, unemployment, housing shortages and deteriorating infrastructure, and can spark conflicts leading to insurrections, terrorism, and war.

Essentially, humans have created an ecological Ponzi scheme. Consumption, as a percentage of Earth’s capacity to regenerate itself, has grown from 73% in 1960 to more than 170% today.

High-consuming countries like Australia, Canada and the US use multiple units of fossil-fuel energy to produce one energy unit of food. Energy consumption will therefore increase in the near future, especially as the global middle class grows.

Then there’s climate change. Humanity has already exceeded global warming of 1°C this century, and will almost assuredly exceed 1.5 °C between 2030 and 2052. Even if all nations party to the Paris Agreement ratify their commitments, warming would still reach between 2.6°C and 3.1°C by 2100.

Our paper found global policymaking falls far short of addressing these existential threats. Securing Earth’s future requires prudent, long-term decisions. However this is impeded by short-term interests, and an economic system that concentrates wealth among a few individuals.

Right-wing populist leaders with anti-environment agendas are on the rise, and in many countries, environmental protest groups have been labeled “terrorists.” Environmentalism has become weaponised as a political ideology, rather than properly viewed as a universal mode of self-preservation.

Financed disinformation campaigns against climate action and forest protection, for example, protect short-term profits and claim meaningful environmental action is too costly—while ignoring the broader cost of not acting. By and large, it appears unlikely business investments will shift at sufficient scale to avoid environmental catastrophe.

Fundamental change is required to avoid this ghastly future. Specifically, we and many others suggest:

>> Abolishing the goal of perpetual economic growth
>> Revealing the true cost of products and activities by forcing those who damage the environment to pay for its restoration, such as through carbon pricing
>> Rapidly eliminating fossil fuels
>> Regulating markets by curtailing monopolisation and limiting undue corporate influence on policy
>> Reining in corporate lobbying of political representatives
>> Educating and empowering women around the globe, including giving them control over family planning.

Many organizations and individuals are devoted to achieving these aims. However their messages have not sufficiently penetrated the policy, economic, political and academic realms to make much difference.

Failing to acknowledge the magnitude and gravity of problems facing humanity is not just naïve, it’s dangerous. And science has a big role to play here.

Scientists must not sugarcoat the overwhelming challenges ahead. Instead, they should tell it like it is. Anything else is at best misleading, and at worst potentially lethal for the human enterprise.

For more than 3.5 billion years, living organisms have thrived, multiplied and diversified to occupy every ecosystem on Earth. The flip side to this explosion of new species is that species extinctions have also always been part of the evolutionary life cycle.

But these two processes are not always in step. When the loss of species rapidly outpaces the formation of new species, this balance can be tipped enough to elicit what are known as “mass extinction” events. Five major mass extinctions have been identified in the geological record, and the sixth extinction is now evident.

The Ohio Valley needs protection from huge explosion & fire hazards

Storing explosive gases under the Ohio River is unacceptable?

From an Invitation by the Concerned Ohio River Residents, CORR, January 15, 2021

Dear Friends and Other Concerned Citizens,

The Ohio Department of Natural Resources is currently considering a permit application to construct the Mountaineer natural gas liquids (NGL) storage facility 2.5 miles from Clarington, OH, along Rt. 7 in Salem Township.

The facility would store up to 3.25 million barrels of highly flammable, explosive natural gas liquids (NGLs) in underground caverns adjacent to and potentially beneath the Ohio River and just one mile from Clarington’s drinking water wells, posing a significant threat to our region’s public health and natural resources.

Join us this Thursday at 6:30 P.M. via Zoom to learn more about the risks posed by the Mountaineer NGL storage facility — and what you can do to help stop it.

Click the link below to RSVP: “MountaineerNGLMeeting”

Please also sign our petition that will be sent to the ODNR regarding this permit.
