Climate change poses an existential threat to society. Rising temperatures and shifting weather patterns are fueling environmental degradation, natural disasters, weather extremes, food and water insecurity, economic disruption, conflict, and terrorism. The World Economic Forum’s Global Risks Report 2024 identifies climate-related changes as some of the most severe risks over the next decade. And nearly two-thirds of the 1.2 million participants in the United Nations Development Programme’s 2021 People Climate Vote said that climate change is a ‘global emergency.’

by Deborah Pirchner, Frontiers science writer Image: Shutterstock.com Women working in agricultural sectors in low- and middle-income countries are disproportionally at risk from climate change induced hazards, such as droughts, floods, or shortened crop-growing seasons. Now, researchers have developed a map showing localities where climate change risk for women in agri-food systems is especially high. Ranking 87 countries, they found that women in central, east, and southern Africa, as well as west and south Asia are at particular risk. Threats posed by the climate crisis disproportionally affect certain communities and social groups that are more exposed. People living in low- and middle-income (LMIC) countries are at heightened risk. Within these countries, women typically face higher climate risk than men. To show where women working in agri-food systems – systems that encompass production, but also post-harvest handling and distribution – are most threated by climate change, an international team of researchers has developed a hotspot map that identifies and ranks localities by threat level. “We show that significant climate hazards, high exposure faced by women in agri-food systems, and high vulnerability faced by women due to systemic gender inequalities converge particularly in central, east, and southern Africa, as well as in […]

by Liad Hollender, Frontiers science writer Image: Shutterstock.com The UN Climate Panel’s latest best estimate is that global warming will end once we reach net zero CO2 emissions – but a study in Frontiers in Science warns significant warming could still occur. Researchers including those from Imperial College London and University of Exeter assess factors controlling global temperatures post ‘net zero’ and offer a pioneering framework for better estimating climate change risks. These risks must inform climate mitigation and adaptation policies to protect future generations. From scorching heatwaves to torrential downpours and devastating storms, the disastrous effects of global warming are sweeping across the world. Being the predicted outcome of burning fossil fuels, our best and only plan to limit warming is to reduce CO2 emissions from human activities to ‘net zero’ – where the amount of CO2 we emit into the atmosphere is equal to the amount we remove from it. To keep within the 1.5°C limit of the 2015 Paris Agreement, this needs to happen as soon as possible. Though the scientific community’s current best estimate from models is that global warming will stop at net zero, an article published in Frontiers in Science raises a red flag. […]

By Prof Martin Siegert, University of Exeter (Cornwall) Image: Shutterstock.com 42 governments around the world have agreed to protect Antarctica’s environment. While the main focus has been on operational activities in Antarctica, global warming caused by fossil-fuel burning by these (and other) countries has left Antarctica on the brink of irreversible change. A new study published in Frontiers in Environmental Science has revealed that, in addition to the influence of gradual global heating, Antarctica is increasingly affected by extreme environmental events; a recognized and predicted outcome of our heating world. Writing as part of Frontiers’ guest editorials series, the study’s lead author – Prof Martin Siegert, deputy vice chancellor of the University of Exeter (Cornwall) – discusses how without there being a rapid shift to net-zero greenhouse gas emissions by 2050, the Antarctic environment will experience ever more drastic changes. Extreme weather events appear to be increasing in size and occurrence, with disastrous outcomes for lives and livelihoods, whether it be from intense heatwaves, severe droughts, deluge rainfall, flooding, and deep storms. All-time records are being shattered not from those of decades ago, but from the last few years and months, exemplifying the human-induced forces we are subjecting our planet […]

By Deborah Pirchner, Frontiers science writer Image: Shutterstock.com Methane production in the livestock sector greatly contributes to greenhouse gas emissions. Animals with four-chambered stomachs produce methane while digesting, however, their manure also emits the gas when decomposing. Recently, natural methane inhibitors have been discussed as a solution. Researchers in Sweden have now examined how supplementing cow feces – rather than cow feed – with such an inhibitor influences methane emission from manure. They found that if a tropical alga was added to dairy cows’ feces, significantly less methane was emitted. Approximately a third of all anthropogenic methane is emitted by ruminant livestock. These animals get nutrients through fermenting food in four-chambered stomachs found in cows, sheep, and goats. They produce methane in two ways: through belching and from the decomposition of their manure under certain conditions. Now, researchers in Sweden have examined if adding the tropical alga Asparagopsis taxiformis (AT), also known as red sea plume, to cow feces impacts greenhouse gas emissions from the manure of dairy cows. They have published their results in Frontiers in Sustainable Food Systems. “We showed that adding AT to the feces of dairy cows significantly reduced methane production from the feces by 44% […]

by Angharad Brewer Gillham, Frontiers science writer Image/Shutterstock.com Scientists investigated whether environmental hazards put people off moving to regions at risk and found that heatwaves and hurricanes deter newcomers, but wildfires don’t. The climate crisis has caused humans to move both within their countries of origin and across borders. Although climate migration is often treated as a phenomenon of the ‘global south’, a team of scientists led by Mahalia Clark at the University of Vermont (UVM) turned the spotlight on the US. The US has experienced numerous destructive weather events recently, which have killed and injured many people and done billions of dollars of damage. But the team found that despite the death toll, more people are moving to areas in the United States that are at serious risk of wildfires. “Our original motivation was the increasing number of headlines each year about record breaking heat waves, hurricanes, and wildfires,” said Clark, a researcher at UVM’s Gund Institute for Environment. “I had been studying natural amenities — features of the climate and environment that are attractive to movers — but I began to wonder if the threat of these hazards might have a deterring effect on migration.” Read original article […]

by Angharad Brewer Gillham, Frontiers science writer Image: Shutterstock.com Researchers using NASA’s Earth observing system find that Antarctic sea ice allows enough light in to let hidden phytoplankton bloom in the Southern Ocean. Until now, we thought the packed sea ice of the Southern Ocean blocked all light from reaching the sea beneath, preventing phytoplankton — tiny algae which are the base of aquatic food webs — from growing there. The less light available, the less the phytoplankton can photosynthesize and therefore the less phytoplankton there will be, heavily restricting life beneath the ice. But research inspired by increasing under-ice blooms of phytoplankton in the Arctic has shown that Antarctic waters also have unexpected denizens, indicating that there is underestimated ecological variability under the ice. Blooms are often spotted as soon as the sea ice begins its seasonal retreat, supported by plenty of light and freshwater with high iron content. Yet a team led by Dr Christopher Horvat of Brown University and the University of Auckland suspected that there would already be potential phytoplankton blooms in waiting. Writing in Frontiers in Marine Science, they described using sampling from independent BGC-Argo floats and climate model output to estimate light availability beneath […]
