World faces ghastly future if urgent climate change action isn’t taken, leading scientists say
The world faces a ghastly future, threatening the survival of all species, unless urgent and decisive action is taken to slow climate change and biodiversity loss, an international group of 17 leading scientists says.
The group has looked at 150 studies to produce a “perspective paper”, published on today, which outlines future trends in biodiversity decline, mass extinction, climate disruption and planetary toxification.
It says all these events are tied to human consumption and population growth and demonstrate the near certainty that these problems will get worse over the coming decades, with negative impacts for centuries to come.
Professor Paul Ehrlich of Stanford University says no political or economic system, or leadership, is prepared to handle the predicted disasters.

Stopping biodiversity loss is nowhere close to the top of any country’s priorities, trailing far behind other concerns such as employment, healthcare, economic growth, or currency stability,” he said. “Humanity is running an ecological Ponzi scheme in which society robs nature and future generations to pay for short-term economic enhancement today.” The study’s lead author Professor Corey Bradshaw of Flinders University in Adelaide said humanity was causing a rapid loss of biodiversity and, with it, the earth’s ability to support complex life.
But he said most people had difficulty grasping the magnitude of the losses and the dangers ahead.
“In fact, the scale of the threats to the biosphere and all its life forms is so great that it is difficult to grasp for even well-informed experts,” he said.
“The problem is compounded by ignorance and short-term self-interest, with the pursuit of wealth and political interests stymieing the action that is crucial for survival.”

Professor Dan Blumstein from UCLA said the scientists were choosing to speak boldly and fearlessly because “life literally depends on it”. “What we are saying might not be popular, and indeed is frightening,” he said. “But we need to be candid, accurate, and honest if humanity is to understand the enormity of the challenges we face in creating a sustainable future.

“Human population growth and consumption continues to escalate, and we’re still more focused on expanding human enterprise than we are on devising and implementing solutions to critical issues such as biodiversity loss.”
Prof Blumstein said by the time the world fully comprehended the impact of ecological deterioration, it would be too late.
“Without fully appreciating and broadcasting the scale of the problems and the enormity of the solutions required, society will fail to achieve even modest sustainability goals, and catastrophe will surely follow,” he said.
The perspective paper is published in Frontiers in Conservation Science.
