Telemedicine use in 2023 reduced monthly carbon dioxide emissions by the equivalent of up to 130,000 gas operated vehicles, suggesting it could have a positive effect on climate change, new UCLA-led research finds. The findings, to be published April 22 in the peer-reviewed American Journal of Managed Care, suggest that telemedicine could have a modest but noticeable impact on the environment by decreasing the number of vehicles traveling to and from medical appointments. They could also have policy implications, said co-senior author Dr. John N.

Climate tipping points pose grave risks to human health—and, unsurprisingly, approaching them while tipsy only makes the fallout more blistering, according to a case study in the New England Journal of Medicine. In this week's issue, NEJM spotlights the effects of the climate crisis on clinical health with a series of case studies. One is the searing story of an inebriated gentleman who regrettably took a one-minute walk while barefoot during the unprecedented 2021 Northwest heat dome. The man walked across asphalt during the extreme weather, in which air temperatures...

How much of a $450 pot would you give to a charity that cuts carbon emissions by investing in renewable energy, and how much would you keep for yourself? That was the question posed in a recent academic experiment. The answers mattered: real money was handed out as a result to some randomly chosen participants. The average person gave away about half the money and kept the rest. But what if you had been told beforehand that the vast majority of other people think climate action is really important? Might...

Environmental activist says ‘be a little less of an individual’ to save the planet To protect the planet this Earth Day, scholars recommended Americans make a conscious effort to cut back on eating meat, traveling, and having children in interviews with the New York Times. “Take a moment to reflect on what a good life within planetary limits look like,” University of Leeds environmental scientist Diana Ivanova told the newspaper. “What does ‘enoughness’ look and feel like?” The first reason the newspaper highlighted came from University of British Columbia Professor...

Editors have highlighted the following attributes while ensuring the content's credibility: Climate change is one of the most pressing challenges of our time, demanding urgent and effective action to mitigate its severe impacts. One barrier to effective climate change action is its polarizing nature, largely driven by the media, as people prefer to consume news that aligns with their political beliefs.

In 1879, explorer and geologist John Wesley Powell reported one of the planet’s most striking climate transitions — a curiosity of nature that’s about to have significant repercussions in Dallas and much of Texas. Powell, the first non-indigenous person to canoe the Grand Canyon, observed a nearly straight line across the spine of the U.S. that marks a stark divide between east and west, shaping how this country developed. Stretching along the 100th meridian — a line of longitude running roughly from Laredo to Bottineau, N.D. — Powell’s line marks...

AUSTIN — Each year, Texas residents, industries and transportation emit more than 800 million tons of greenhouse gases with an impact on climate change that is comparable to Germany, which has a population 2.5 times larger. Despite the state’s relatively high emissions, according to data from the Texas Commission on Environmental Quality and the European Union, Texas has done little to address past and future climate change. California, the only state that comes close to Texas’ level of planet-warming greenhouse gases, has enacted aggressive policies to reduce emissions.

Canada's top candidates talk up fossil fuels as climate slips down agenda As the threat posed by US President Donald Trump tops Canada's federal election agenda, the issue of the country's contribution to global warming has been largely overshadowed. The two main contenders are pushing plans for new energy infrastructure as the country seeks to pivot away from its reliance on the US. Mark Carney's Liberals are promising to make Canada a global superpower in both conventional and green energy. The Conservatives under Pierre Poilievre want to invigorate the oil...

Editors have highlighted the following attributes while ensuring the content's credibility: Farmers apply nitrogen fertilizers to crops to boost yields, feeding more people and livestock. But when there's more fertilizer than the crop can take up, some of the excess can be converted into gaseous forms, including nitrous oxide, a greenhouse gas that traps nearly 300 times as much heat in the atmosphere as carbon dioxide. About 70% of human-caused nitrous oxide comes from agricultural soils,...
