Scientists issue dire warning after discovering why viruses and bacteria could soon become more dangerous: 'Urgent need for global cooperation'
A new study predicts that warming global temperatures could make it harder to fight infections caused by bacteria, viruses, and other microorganisms.
A team of Chinese scientists has projected that if we continue down a path of heavy reliance on planet-warming fuels, antimicrobial resistance — the ability of microorganisms like bacteria and viruses to survive against the drugs designed to treat them — could rise by more than 2% globally by 2050.
The paper, summarized by the University of Minnesota, also predicted that if countries are able to meet sustainable development goals, AMR levels could be reduced by about 5%.
But even if some of the sustainable development goals are met, the authors say an overheating planet could still raise AMR levels due to factors like more extreme weather events that bring heavy precipitation and flooding, or altered animal habitats and natural microbial ecosystems that facilitate the spread of zoonotic and vector-borne diseases.
"These challenges highlight the urgent need for global cooperation in developing and implementing strategies to address the interconnected and evolving threats posed by climate change and AMR," they said.
AMR "puts many of the gains of modern medicine at risk," according to the World Health Organization, which said it makes infections harder to treat and makes other medical procedures like chemotherapy riskier. In addition to death and disability, the organization also projects AMR could result in $1 trillion in additional healthcare costs by 2050, and $1-3.4 trillion in gross domestic product losses per year by 2030.
Still, it is just one of the many health concerns associated with rising global temperatures.
For instance, scientists say a warmer planet is likely to blame for an uptick of infections from "brain-eating" amoebas, which led to several deaths in India and Israel in 2024. Plus, warmer temperatures are helping disease-carrying ticks spread further west and north in North America. For example, Lyme disease risk doubled in the Canadian province of Quebec and tripled in Manitoba between 2000 and 2015.
A number of governments are taking steps to address planet-heating pollution, which will also help clean up the air we breathe. For instance, Wales is banning most new roadway projects to cut down on traffic pollution.

China 'firmly rejects' US claim that it violated tariff deal
China said Monday it "firmly rejects" US claims that it had violated a sweeping tariffs deal, as tensions between the two economic superpowers showed signs of ratcheting back up. Beijing and Washington last month agreed to slash staggeringly high tariffs on each other for 90 days after talks between top officials in Geneva. But top Washington officials last week accused China of violating the deal, with Commerce Secretary Howard Lutnick saying Beijing was "slow-rolling" the agreement in comments to "Fox News Sunday". China hit back Monday, saying Washington "has made bogus charges and unreasonably accused China of violating the consensus, which is seriously contrary to the facts". "China firmly rejects these unreasonable accusations," its commerce ministry said in a statement. US President Donald Trump said last week that China had "totally violated" the deal, without providing details. Beijing's commerce ministry said it "has been firm in safeguarding its rights and interests, and sincere in implementing the consensus". It fired back that Washington "has successively introduced a number of discriminatory restrictive measures against China" since the Geneva talks. The ministry cited export controls on artificial intelligence chips, curbs on the sale of chip design software and the revocation of Chinese student visas in the United States. "We urge the US to meet China halfway, immediately correct its wrongful actions, and jointly uphold the consensus from the Geneva trade talks," the ministry said. If not, "China will continue to resolutely take strong measures to uphold its legitimate rights and interests," it added. - Trump-Xi talks? - US officials have said they are frustrated by what they see as Chinese foot-dragging on approving export licences for rare earths and other elements needed to make cars and chips. But Washington's Treasury Secretary Scott Bessent looked to ease the pressure on Sunday, saying the two sides could arrange a call between their respective heads of state to resolve their differences. "I'm confident... this will be ironed out" in a call between Trump and Chinese President Xi Jinping, Bessent said on CBS's "Face the Nation". He added, however, that China was "withholding some of the products that they agreed to release", including rare earths. On when a Trump-Xi call could take place, Bessent said: "I believe we will see something very soon." China has been less forthcoming, and the commerce ministry's statement on Monday did not mention any planned conversations between the two leaders. The Geneva deal was "an important consensus reached by the two sides on the principle of mutual respect and equality, and its results were hard-won", the ministry said. It warned Washington against "going its own way and continuing to harm China's interests". Global stocks finished mixed on Friday after Trump made his social media post accusing Beijing. The Hong Kong stock exchange was down around 2 percent shortly after opening on Monday. mjw/je/rsc

Ontario inks trade deals with Saskatchewan and Alberta ahead of meeting with Carney
SASKATOON - Alberta and Saskatchewan signed agreements with Ontario on Sunday to remove trade barriers ahead of a meeting with Prime Minister Mark Carney to hash out a plan they hope will supercharge the economy. The memorandum of understanding between Saskatchewan and Ontario sees both provinces mutually recognize each other's goods, workers and investment, while a statement from the Alberta government says its MOU with Ontario aims to improve the free flow of goods and services between the two provinces. The Alberta statement also says the agreement will simplify requirements for regulated professions such as skilled trades, making it easier for professionals to work across provincial boundaries. Both deals, which were signed in Saskatoon ahead of a first ministers meeting in the city Monday, pledge to advance measures that would see willing provinces allow the sale of alcohol directly to consumers. Ontario Premier Doug Ford said the deals help grow provincial economies as U.S. President Donald Trump threatens more tariffs on Canadian steel. 'We're going to band together,' Ford said when talking about the agreement with Saskatchewan. 'We've never been attacked by any leader in the world like we have by President Trump. He doesn't give two hoots about Canada.' '(But) he's going to have a rude awakening. We're going to fight like we've never fought before.' It's Ford's latest deals with provinces to open trade, measures he says could unlock $200 billion in economic gains. Alberta said its agreement with Ontario also welcomes the possibility of Ontario joining the New West Partnership Trade Agreement, which has worked to streamline regulations and standards across British Columbia, Alberta, Saskatchewan and Manitoba. 'It's time to stop letting outdated rules hold us back and show Canadians what real economic leadership looks like,' Alberta Premier Danielle Smith said in a news release Sunday. The premiers are meeting Monday with Carney to discuss major nation-building projects that could boost the economy. Ford said the prime minister needs to remove regulations to make it easier to build projects. That includes scrapping the Impact Assessment Act, he said. 'It all depends on the speed right now (in getting projects built),' Ford said. Saskatchewan Premier Scott Moe said he's hoping for a port-to-port corridor in Western Canada to ship more goods out of northern B.C. and Hudson Bay in northern Manitoba. 'It's the largest single opportunity that I've seen in my lifetime,' Moe said. 'All we need to do is come together, and then stand by side by side and defend the opportunities we have from a trade perspective. Defend them like hell.' Building more oil and gas pipelines must be part of Canada's future, Moe added. 'If we truly are going to become the strongest economy in the G7 nations, if we truly are going to become a global energy superpower, it means we need to open up the opportunity for all of our industries,' Moe said. 'I think (Carney) is aware that there's a feeling of alienation in certain areas of the nation.' Both Alberta and Saskatchewan have long had grievances with former prime minister Justin Trudeau, who they say made it difficult for the industry to build energy projects. Smith has said more pipelines are the only way to get more products to market efficiently and without one, there could be a national unity crisis. She has called on Carney to scrap the oil and gas emissions cap and clean electricity regulations, repeal industrial carbon pricing and overhaul regulations. But getting a pipeline through Quebec might be difficult. The province had opposed the former Energy East oil pipeline from Alberta and rejected the GNL Quebec project in Saguenay in 2021. However, Quebec Premier François Legault said last month he's open to some projects. Ford said all provinces must be on the same page for any pipeline to move forward. 'I hope (Legault) is going to bring a pipeline through,' he said. 'Last time I checked, Quebecers drive cars, they need gas.' This report by The Canadian Press was first published June 1, 2025.

Northern lights could be visible tonight if hazy skies clear up
COLUMBUS (WCMH) — A powerful solar eruption from the sun's surface early on June 1 sent charged particles streaming toward Earth at more than four million miles per hour, which could provide a view of the northern lights across portions of the United States and Canada Sunday night, and possibly Monday night. The geomagnetic storm reached the level of G4 Sunday morning on a scale of 1 (minor) to 5 (extreme), which brings a higher likelihood of seeing the northern lights farther south than usual, in places such as northern California, Illinois, and the northern Mid-Atlantic region. The best time to look for the shimmering display of color is between 10 p.m. and 2 a.m. near the northern horizon if you reside in a more rural area with darker skies away from city lights. However, smoke from Canadian wildfires may preclude the view in some areas of the country. A coronal mass ejection (CME) sends electrically charged particles (ions) and magnetic material streaming into space, generating currents in the magnetic field. When the solar wind collides with Earth's magnetic field (magnetosphere), the interaction with gases (oxygen, nitrogen) in the upper atmosphere produces streaks or curtains of light, known as the aurora borealis in the Northern Hemisphere. The most common color arising from collisions between solar particles (atoms) and oxygen molecules is green, because the red veils occur higher up in the atmosphere and are harder to view. Nitrogen interactions at lower altitudes trigger blue curtains of light. Last year on May 10, a G4 storm triggered spectacular views of the northern lights in parts of central Ohio. Another view of the northern lights occurred on Oct. 10, 2024, but was much more limited in our area. Severe geomagnetic storms can affect high-frequency communications, disrupting GPS systems and low-frequency satellite navigation signals. In extreme events, the CME voltage can impact the electric energy or power grid, resulting in regional blackouts. Copyright 2025 Nexstar Media, Inc. All rights reserved.
