New UNSW research reveals dramatically higher loss of GDP under 4°C warming

New projections by the UNSW Institute for Climate Risk & Response (ICRR) reveal a 4°C rise in global temperatures would cut world GDP by around 40% – a stark increase from previous estimates of around 11%.

(Press-News.org) New projections by the UNSW Institute for Climate Risk & Response (ICRR) reveal a 4°C rise in global temperatures would cut world GDP by around 40% by 2100 – a stark increase from previous estimates of around 11%. 

The recently-published analysis fixes an oversight in the current economic model underpinning global climate policy, toppling previous carbon benchmarks. 

The results support limiting global warming to 1.7 °C, which is in line with significantly faster decarbonisation goals like the Paris Agreement, and far lower than the 2.7°C supported under previous models.

Accounting for an interconnected world 

Lead researcher Dr Timothy Neal, a Scientia Senior Lecturer in the School of Economics and also the ICRR, says his analysis uses traditional economic frameworks that weigh immediate transition costs against long term climate damages, but refine a key input.

"Economists have traditionally looked at historical data comparing weather events to economic growth to cost climate damages,” he says.

What they fail to account for, he says, are interruptions to the global supply chains currently buffering economic shocks.

“In a hotter future, we can expect cascading supply chain disruptions triggered by extreme weather events worldwide.”

Dr Neal says the economic case for stronger climate change actions is clear. 

“Because these damages haven’t been taken into account, prior economic models have inadvertently concluded that even severe climate change wasn't a big problem for the economy – and it’s had profound implications for climate policy.” 

The local-only damage models have been used in the economic forecasting that has shaped the major powers’ climate policies and played a crucial role in international agreements. 

No nation immune to climate change harm 

Dr. Neal says the updated projection should underscore to all nations that they are vulnerable to climate change. 

“There’s an assumption that some colder countries, like Russia or Canada, will benefit from climate change, but supply chain dependencies mean no country is immune.” 

But, Dr. Neal says, there’s still work to be done. His research doesn’t account for climate adaptation, like human migration, which is politically and logistically complex and not yet fully modelled. 

“We continue learning from how we see climate change impacting our economy right now, from rising food prices to insurance costs, and we need to be responsive to new information if we’re going to act in our best interest.”

Discovery of Quina technology challenges view of ancient human development in East Asia

2025-03-31
While the Middle Paleolithic period is viewed as a dynamic time in European and African history, it is commonly considered a static period in East Asia. New research from the University of Washington challenges that perception. Researchers discovered a complete Quina technological system — a method for making a set of tools — in the Longtan site in southwest China, which has been dated to about 50,000 to 60,000 years ago. Quina technology was found in Europe decades ago but has never before been found in East Asia. The team published its findings March ...

A new clue to how multicellular life may have evolved

A new clue to how multicellular life may have evolved
2025-03-31
Life emerged on Earth some 3.8 billion years ago. The “primordial soup theory” proposes that chemicals floating in pools of water, in the presence of sunlight and electrical discharge, spontaneously formed organic molecules. These building blocks of life underwent chemical reactions, likely driven by RNA, eventually leading to the formation of single cells. But what sparked single cells to assemble into more complex, multicellular life forms? Nature Physics published a new insight about a possible driver of this key step in evolution — the fluid ...

New study validates lower limits of human heat tolerance

2025-03-31
A study from the University of Ottawa’s Human and Environmental Physiology Research Unit (HEPRU) has confirmed that the limits for human thermoregulation—our ability to maintain a stable body temperature in extreme heat—are lower than previously thought. This research, led by Dr. Robert D. Meade, former Senior Postdoctoral Fellow and Dr. Glen Kenny, Director of HEPRU and professor of physiology at uOttawa's Faculty of Health Sciences, highlights the urgent need to address the impacts of climate change on human health. The study found that many regions may soon experience heat and humidity levels that exceed the safe limits ...

UTA takes lead with mobile lab to address rural health care crisis

UTA takes lead with mobile lab to address rural health care crisis
2025-03-31
Texas has the most rural residents of any state, with nearly 3 million people spread across a vast landscape. If rural Texas were its own state, it would rank as the 36th most populous. Yet, rural Texans face significant barriers to health care that their urban counterparts do not. More than a quarter of the state’s 172 rural counties lack a hospital, and those with at least one hospital often struggle with a shortage of qualified health care personnel, such as nurses and first responders. To address these growing challenges, The University of Texas at Arlington introduced its new Mobile Simulation Lab on Friday. It’s the first in Texas dedicated ...

New flexible hydrogel could improve drug delivery for post-traumatic osteoarthritis treatment

2025-03-31
Post-traumatic osteoarthritis (PTOA) is a condition that affects joints after an injury. Current treatments focus on relieving symptoms but do not prevent or stop the progression of the condition. Although emerging therapies have shown promise in preclinical studies, a major obstacle is delivering these therapies effectively into the joint, a highly dynamic environment subjected to constant mechanical stress. Researchers at Mass General Brigham have created a new hydrogel to improve drug delivery for treating PTOA. The hydrogel, ...
