Scientists raise red flag over concerning trend among polar bears — here's why it has bigger implications
The U.S. Fish and Wildlife Service has estimated that there have been sharp declines in Alaska's polar bear population.
Alaska polar bears face serious threats because of rising global temperatures and human activity.
As Defenders of Wildlife reported, approximately one-tenth of the global polar bear population lives around Alaska's Beaufort Sea and Chukchi Sea. The estimates of their numbers from earlier this year signal that polar bears' livelihood is at risk, and their long-term survival prospects are dim.
The FWS estimated that only approximately 819 polar bears are in the Southern Beaufort Sea population. Bears in this region saw a 40% population decline during the 2000s. They are considered one of the most at-risk populations of polar bears worldwide.
Along the Chukchi Sea, the FWS estimated the polar bear population to be around 2,937. Although this population is considered more stable than that of the Beaufort Sea, officials aren't fully confident in the accuracy of this number since tracking them is quite challenging.
The Alaskan polar bear population's decline is attributed to sea ice declines and behavioral changes, as bears must spend more time on land in the summer. Oil and gas development also threatens polar bear habitats because drilling and dirty energy exploration projects displace them and destroy the resources they need to survive.
Declining polar bear populations disrupt the Arctic food chain and the people and animals who rely on the region's natural resources. Polar bears are the top predators in the region and help balance the natural ecosystem.
Unfortunately, this isn't an isolated issue to just Alaska. Polar bears also struggle to survive in other regions, while even grizzly bears are dying in increasingly disturbing numbers because of environmental conditions and extreme weather shifts.
Polar bear population declines indicate the overall health of the Arctic environment and are a cultural symbol for Indigenous communities. Protecting and rebuilding their populations is crucial to preserving regional biodiversity and cultural heritage.
Fortunately, scientists have been improving polar-bear tracking strategies to monitor their populations and inspire conservation efforts. Reducing our world's reliance on dirty energy and choosing clean energy for power can slow the steadily rising temperatures and help protect polar bears.
As an individual, you can spread the news about declining polar bear populations by discussing critical climate issues like sea ice melt and oil drilling with people you know. You can also contact your elected officials to urge them to support sustainable policies that protect polar bears.

Researchers call for urgent exploration of methods to cool Earth
It is already obvious that some governments are not acting fast enough to keep the planet's temperature from rising dangerously. While it is essential to continue to concentrate on reducing methane and carbon dioxide emissions as quickly as possible, other methods of cooling the planet need to be urgently explored, according to academics at the University of Cambridge's engineering department. Related: UK scientists to launch outdoor geoengineering experiments One of the problems is that many of the ideas put forward so far, including injecting sulphates into the atmosphere to reflect sunlight back into space, could do more harm than good. This is because sulphates cause acid rain and interfere with rainfall patterns. To avoid controversy researchers are experimenting with alternatives to sulphates, substances that reflect sunlight but are benign. They will hoist them into the stratosphere using weather balloons then recover them to see what changes this exposure causes. No materials will be released but their cooling effect and whether they could otherwise be harmless can be gauged. Other ideas like drilling holes in the Arctic ice in the winter and pumping seawater over existing ice floes in below freezing air temperatures to thicken them are also being tried, along with spraying seawater to form clouds over the ocean, also to reflect sunlight. If these ideas are otherwise harmless, and work, they might yet save us.

As the ocean warms, a new study found it's also changing color
For thousands of years, writers have come up with increasingly creative ways to describe the 'wine-dark sea.' But a new study suggests that modern poets may be faced with a slightly different palette. A study published Thursday in the journal Science found that the ocean is changing color as it warms. By analyzing satellite data from 2009 to 2022, researchers from Duke University and the Georgia Institute of Technology noticed that waters near the equator were getting greener, while areas near the poles were turning bluer. Lead author Haipeng Zhou calls it 'this greener greens or bluer blues phenomenon.' The culprit, the paper suggests, is the teeny tiny plant-like creatures that form the building blocks of the marine food web — phytoplankton. Phytoplankton are filled with a green pigment called chlorophyll that allows them to absorb energy from sunlight through photosynthesis. As waters near the equator warm, they're less hospitable to the microscopic critters, so the water appears bluer. At the poles, the colder water is far more nutrient-dense, so there's lots more phytoplankton to go around, giving the waters a rich, blue tinge. It's not a new phenomenon. There's a reason the Caribbean is known as the land of dazzling turquoise waters, while Arctic waters are a dark navy contrast to the ivory ice floes around them. But Zhou, who began the research at Duke University and completed it as a postdoctoral researcher at Georgia Tech, found that as the ocean warms, this phenomenon is getting stronger. Their study only looked at the open ocean, not coastal waters. Near the coast, there are plenty of complicating factors that make it hard to clearly point to phytoplankton as the main cause of color changes, like dirt and sand floating in the water, shifting winds, pollution or even seagrass die off. To understand the concentrations of phytoplankton, the research team relied on a National Oceanic and Atmospheric Administration database made up of samples scooped from various research cruises all over the world. This database, plus satellite imagery, helped show the color shift in different regions of the ocean. The changing levels of phytoplankton could be bad news for fish in the tropics, or for communities that rely on those fish. But it could also be a boon for their northern and southern cousins. 'We all know that phytoplankton is the bottom of the food chain. Any impact on phytoplankton will have impacts on its predators,' Zhou said. Phytoplankton need sun and nutrients to flourish, but when the ocean warms, the individual layers that make up the sea grow more stratified, so it's harder for phytoplankton to float up and down the water column to access the same light and nutrients they're used to, he said. So while scientists can clearly say that warmer waters lead to fewer phytoplankton, and they know that climate change is one of the main reasons the oceans are heating up, it's not clear if climate change is the reason for the color shift. 'We need longer records, 30 years, 40 years, to make us more confident whether it is linked to climate change or global variability,' Zhou said. The study only looked at about 20 years of data, which Zhou said is enough to confidently say that something has changed, but not long enough to know what caused that change. Other factors can and do affect water temperature, like the shift in trade winds over the Atlantic that led to a coral-killing marine heat wave in 2023. 'The study period was too short to rule out the influence of recurring climate phenomena such as El Niño,' wrote co-author Susan Lozier, Dean of the College of Sciences at Georgia Tech, in a statement. However, Zhou added, more research may very well find that this color-shifting trend continues into the future as human-caused climate change continues to heat up the oceans. 'The temperature of the water is rising. While there's no evidence showing that this progress will slow down, it's very likely we'll have warmer waters in the future, which means we'll have a continuous impact on the ocean ecosystem.'

Arctic warming spurs growth of carbon-soaking peatlands
Arctic peatlands are expanding as the climate warms, new research showed Thursday, a change that could slow global heating in the near term but have the opposite effect in future. Peatlands are the largest terrestrial store of carbon, locking away twice as much heat-trapping CO2 from the atmosphere in their waterlogged soils as all the world's forests. These carbon-rich reservoirs, composed of partially decayed organic matter, only cover three percent of Earth's surface, and generally fade out in the far north, where harsh weather limits plant growth. But warmer temperatures caused by climate change have improved growing conditions for plants in the Arctic, and satellite data has shown a general "greening" of this frosty region. Using drones, satellite imagery and on-the-ground observations, an international team of scientists assessed peatlands in the European and Canadian Arctic to see if they had benefited from warmer climes. They found strong evidence that peatlands "have likely undergone lateral expansion over the last 40 years" in the Arctic, which is the fastest-warming region on Earth. "The permafrost thaws a little, provides a water source for vegetation, and surface vegetation recovers. In this study, we specifically see a lateral expansion," Michelle Garneau, a professor at the University of Quebec in Montreal, and co-author of the study, told AFP. The most marked change was observed where summer temperatures have risen the most, such as in the Norwegian archipelago of Svalbard. "All these new vegetated surfaces that didn't exist three decades ago are currently actively absorbing carbon," Garneau added. How Arctic peatlands respond to climate change in future is "still highly uncertain", said the study, published in the peer-reviewed journal Communications Earth & Environment. Recent modelling suggests these northern peatlands "may become a carbon source from mid-century" as they dry out and permafrost thaws, the study said. They are also at risk from wildfires, which release masses of stored up carbon at once. "This means that in the short term, these expanding peatlands are a growing carbon sink in the Arctic," said study co-author Karen Anderson, a professor from the University of Exeter, which led the research. "But in the future, this could switch back, and this will happen because of higher temperatures and potentially things like fires," she told AFP. As peatlands expand, they also release methane, a potent greenhouse gas with far more heat-trapping capacity than CO2, though these emissions decline over time. "So while our study gives us some positive news, it does not detract from the urgent need to reduce greenhouse gas emissions and stabilise our climate," said Anderson. jmi/np/jhb
