Why Climate Change Could Mean More Delayed Flights 

    No one enjoys a delayed flight, but as our weather gets warmer, we can expect more of them.

    That's according to experts, who say that the heat of the summer might cause more delays.

    Bloomberg looked at US data for flight delays at airports in Chicago and New York from June to August in 2022 and from January to March in 2023. It found that there were more delayed flights in the summer months at both airports. 

    When the temperature rises above 39 degrees Celsius, things get very difficult for airlines, Bijan Vasigh, a professor at Embry-Riddle Aeronautical University in the US, told Bloomberg.

    The air is thinner when it gets hot and that makes it harder for planes to take off. In thinner air there is not as much lift, so more power is needed.

    When they need more power, it helps to have a lighter airplane.

    That might mean pilots have to make last-minute decisions to reduce the weight on board by dumping fuel, passengers or baggage — meaning the plane will probably be delayed.

    The problem gets worse at airports that are at a higher altitude where the air is already thinner, and at airports with short runways, since planes need more space to get up to a high speed.

    But thin air is not the only problem. Smoke from wildfires — that have been happening all around the world in the summer of 2023 — can also cause flights to be delayed and canceled.    

    Of course, the summer is also a busy time when millions of people fly, and weather is not the only cause of delays — but our hotter climate doesn't seem to be helping.

There have been 18 opioid-related deaths in Nova Scotia so far this year

        Paramedics in Nova Scotia used naloxone to save 165 people from opioid overdoses in 2018 and 188 people in 2019. In 2020, 102 people were saved as of July 31.

        Eight years ago, Matthew Bonn watched his friend turn blue and become deathly quiet as fentanyl flooded his body. Bonn jumped in, performing rescue breathing until paramedics arrived. That was the first time Bonn fought to keep someone alive during an overdose.

        But it wouldn't be his last. Over the years, he tried more dangerous ways to snap people out of an overdose.

        "I remember doing crazy things like throwing people in bathtubs, or, you know, giving them cocaine. As we know now, that doesn't help," said Bonn, a harm-reduction advocate in Halifax. "But ... in those panic modes, you try to do whatever you can to keep that person alive."

        This was before naloxone – a drug that can reverse an opioid overdose – became widely available to the public. In 2017, the Nova Scotia government made kits with the drug available for free at pharmacies.

        Whether used by community members or emergency crews, naloxone has helped save hundreds of lives in the province. Matthew Bonn is a program co-ordinator with the Canadian Association of People Who Use Drugs, and a current drug user himself.

        Almost every other day in Nova Scotia, paramedics and medical first responders in the province use the drug to reverse an opioid overdose, according to Emergency Health Services (EHS).

        While plastic refuse littering beaches and oceans draws high-profile attention, the Food and Agriculture Organization’s (FAO) Assessment of agricultural plastics and their sustainability: a call for action suggests that the land we use to grow our food is contaminated with even larger quantities of plastic pollutants. “Soils are one of the main receptors of agricultural plastics and are known to contain larger quantities of microplastics than oceans”, FAO Deputy Director-General Maria Helena Semedo said in the report’s foreword.

        According to data collated by FAO experts, agricultural value chains each year use 12.5 million tonnes of plastic products while another 37.3 million are used in food packaging. Crop production and livestock accounted for 10.2 million tonnes per year collectively, followed by fisheries and aquaculture with 2.1 million, and forestry with 0.2 million tonnes. Asia was estimated to be the largest user of plastics in agricultural production, accounting for almost half of global usage. Moreover, without viable alternatives, plastic demand in agriculture is only set to increase. As the demand for agricultural plastic continues surge, Ms. Semedo underscored the need to better monitor the quantities that “leak into the environment from agriculture”.

        Since their widespread introduction in the 1950s, plastics have become ubiquitous. In agriculture, plastic products greatly help productivity, such as in covering soil to reduce weeds; nets to protect and boost plant growth, extend cropping seasons and increase yields; and tree guards, which protect young plants and trees from animals and help provide a growth-enhancing microclimate. However, of the estimated 6.3 billion tonnes of plastics produced before 2015, almost 80 per cent had never been properly disposed of. While the effects of large plastic items on marine fauna have been well documented, the impacts unleashed during their disintegration potentially affect entire ecosystems.
