(Press-News.org) Key takeaways:
A new study suggests global future economic growth will be slower than predicted, with developing nations taking longer to close the wealth gap and approach the income of wealthier nations
Governments need to start planning for slower-growth scenarios, which may involve wealthier nations providing lower-income countries with financing for climate change adaptations
National debt and debt-ceiling talks may become more contentious in the coming decades
The global economy will grow slower in the 21st century than economists have expected, a finding that has implications for our ability to adapt to climate change in the coming decades, according to new research.
A new study projecting the economic futures of four income groups of countries over the next century finds growth will be slower than predicted, with developing countries taking longer to close the wealth gap and approach the income of wealthier nations. What economists have thought of as a worst-case scenario for global economic growth may, in fact, be a best-case scenario, according to the new study published today in Communications Earth & Environment.
The findings suggest governments need to start planning for slower growth and wealthier countries may need to help lower-income nations finance climate change adaptations in the coming decades, according to the study authors.
“We're at a point where we maybe need to significantly increase financing for [climate] adaptation in developing countries, and we're also at a point where we might be overestimating our future ability to provide that financing under the current fiscal paradigm,” said Matt Burgess, a CIRES fellow, director of the Center for Social and Environmental Futures, and assistant professor of environmental studies at CU Boulder who led the new study.
“We can now start to winnow down the range of possibilities and move forward in more tangible ways,” said Ryan Langendorf, a postdoctoral scholar at CU Boulder and co-author of the new study.
In the new study, Burgess and his colleagues used two economic models to project how much the global economy will grow over the next century and how quickly developing countries will approach the income levels of wealthier nations.
Both models found the global economy will continue to grow, but that growth will be slower than most economists expected and there will be a larger income gap between wealthier and poorer nations. This means richer countries may need to help finance climate adaptations for poorer countries, and debt-ceiling crises, like what the United States experienced this spring, may become more common.
“Slower growth than we think means higher deficits than we expect, all else equal,” Burgess said. “That means debt would likely become more contentious and important over time, and could mean more frequent debt-ceiling fights.”
Similar to a flight emergency, where individuals should put their own oxygen masks on first, wealthier nations should focus on getting their own financial houses in order so they can be in a position to support lower-income nations in financing climate adaptations, according to the researchers.
“We're talking about relatively less growth, relatively more inequality, but we're still talking about a world that is richer than today and more equal across countries than today's world,” Burgess said.
Still, many wealthy nations are accustomed to growing their way out of debt, but that may not be possible under the new scenario, according to Ashley Dancer, a graduate student at CU Boulder and co-author of the study.
“The next question is: what are some ways that we should be or could be helping [lower-income countries] adapt, if the expectation is that they're not going to meet the level of wealth that would allow them to do that quickly and aggressively?” Dancer said.

New analysis: Kaepernick was denied his “right to work” because he, like other Black male athletes before him, challenged structural racism and white supremacy
2023-06-23
A nascent literature is emerging that analyzes the case of Colin Kaepernick who was “locked out” of the National Football League (NFL) beginning in 2017 because he chose to protest police brutality, systemic racism, and white supremacy. Using status expectations states theory and prototypicality theory, this research re-conceptualizes Kaepernick’s lock-out as an infringement on his right to work. First, researchers utilize a modified case-study approach comparing his experiences to those of six other Black male athletes who were “locked out.” Second, researchers utilize data and “matched cases” to demonstrate empirically ...
All the immunity, none of the symptoms
2023-06-23
LA JOLLA (June 23, 2023)—Worldwide, more than a million deaths occur each year due to diarrheal diseases that lead to dehydration and malnutrition. Yet, no vaccine exists to fight or prevent these diseases, which are caused by bacteria like certain strains of E. coli. Instead, people with bacterial infections must rely on the body taking one of two defense strategies: kill the intruders or impair the intruders but keep them around. If the body chooses to impair the bacteria, then the disease can occur without the diarrhea, but the infection can still be transmitted—a process called asymptomatic carriage.
Now, Salk scientists have found that ...
Higher efficiency catalyst key to green hydrogen
2023-06-23
The race to make the widespread use of intermittent renewable energy a reality has taken a step forward with new research by experts from the University of Adelaide who are improving the efficiency of iridium-based catalysts.
“Currently it is difficult for commercial iridium oxide catalysts to achieve high activity and stability at the same time in proton exchange membrane water electrolysis (PEMWE),” said the University of Adelaide’s Associate Professor Yao Zheng, ARC Future Fellow, School of Chemical Engineering.
“We have found that a lattice-water-assisted mechanism – a ...
Drug decelerates bacterial race to antibiotic resistance
2023-06-23
A team of researchers at Baylor College of Medicine is gaining ground in their search for solutions to the global problem of bacterial antibiotic resistance, which was responsible for nearly 1.3 million deaths in 2019.
The team reports in the journal Science Advances a drug that, in laboratory cultures and animal models, significantly reduces the ability of bacteria to develop antibiotic resistance, which might prolong antibiotic effectiveness. The drug, called dequalinium chloride (DEQ), is a proof-of-concept for evolution-slowing drugs.
“Most people with bacterial infections ...

FSU assistant professor’s research helps determine origins of plate tectonics
2023-06-23
A Florida State University faculty member’s research is helping to uncover more about the conditions necessary for the beginnings of life on Earth.
FSU Assistant Professor Richard Bono was part of a multi-institution team that found evidence that the planet’s magnetic field was stable from 3.9 to 3.4 billion years ago, a time when scientists think life may have first originated. Their research was published in Nature.
Bono explained more about what the team found and its implications for the origins of plate tectonics and life on Earth.

The force of blows to the head, not just how many, raises likelihood of CTE
2023-06-23
For years, researchers studying chronic traumatic encephalopathy, or CTE, believed the primary cause of it was repetitive hits to the head, whether or not those hits caused concussions. They believed the more frequently that a person sustained head blows, the more likely they were to develop neurological and cognitive struggles later in life.
A new collaborative study conducted by researchers at Boston University, Mass General Brigham, and Harvard Medical School—using brains donated to BU’s ...

Researchers show how a tumor cell’s location and environment affect its identity
2023-06-23
Using 3-D models of ovarian cancer tumors, scientists found differences in gene activity based on where a cell is in a tumor, demonstrating how a cell’s location and environment in a cancerous tumor can strongly influence which genes are active and the cell’s role in the cancer’s biology. More specifically, the team co-led by researchers at the National Center for Advancing Translational Sciences (NCATS), part of the National Institutes of Health, showed that gene activity in cells at or near a tumor’s surface differed from that of cells closer to the tumor center.
The approach pairs the use of a technology to reveal the genetic activity of single ...
