New research highlights the health and environmental benefits of substituting animal proteins with plant-based alternatives in Canadian diets, finding significant gains in life expectancy and reductions in carbon footprint, especially when replacing red and processed meats. Benefits vary by the type of animal protein replaced and show a sex difference in health outcomes.Researchers at McGill have discovered that substituting plant protein foods for red and processed meats can extend life expectancy and reduce the impact…

A privately funded satellite is set to push methane tracking into a new era, once it launches into space on Monday.A collaborative mission between Environmental Defense Fund, Google, the Government of New Zealand and several other partners, MethaneSAT will track methane emissions around the globe in attempts to identify and quantify sources spewing the climate-heating greenhouse gas. For 20 years after its release into the atmosphere, methane gas is 80 times more harmful than carbon dioxide in its ability to increase…

For the ninth straight month, Earth has obliterated global heat records — with February, the winter as a whole and the world's oceans setting new high-temperature marks, according to the European Union climate agency Copernicus.The latest record-breaking in this climate change-fuelled global hot streak includes sea surface temperatures that weren't just the hottest for February, but eclipsed any month on record, soaring past August 2023's mark and still rising at the end of the month.And February, as well the previous two…

The Current24:29Will lab-grown meat ever reach our plates?Read transcribed audio.What's cultivated, meat-like, and could help lower greenhouse gas emissions? Lab-grown meat — and it could be the future of protein.Sometimes known as cultured meat, lab-grown meat is unlike plant-based alternatives from companies such as Beyond Meat or Impossible Foods. Instead, it's made by taking a few stem cells from an animal's muscle, then placing them in a nutrient broth where they multiply and are triggered to turn into muscle…

The world just experienced its hottest January on record, but that wasn't the only new record it set, the European Union's Copernicus Climate Change Service (C3S) said on Thursday.For the first time, the global temperature pushed past the internationally agreed upon warming threshold for an entire 12-month period, with February 2023 to January 2024, running 1.52 C, according to C3S.Last month surpassed the previous warmest January, which occurred in 2020, in C3S's records going back to 1950.Every month since June has been…

Researchers found that carbon credits for efficient cookstoves are overestimated by a factor of 10, challenging the effectiveness of these offsets in combating climate change and calling for a shift towards cleaner, health-standard-compliant cooking solutions. Credit: SciTechDaily.comNew study finds that global carbon markets overcredit cookstove greenhouse gas reductions by a factor of 10.The fastest growing type of offset on the global carbon market subsidizes the distribution of efficient cookstoves in developing…

Canada's forestry sector is responsible for far more greenhouse gas emissions than show up in official tallies, potentially leading to policies that aren't in line with the country's climate goals, a new study suggests.The peer-reviewed study, published in the academic journal Frontiers in Forests and Global Change, found that annual greenhouse gas emissions attributable to forestry between 2005 and 2021 were, on average, nearly 91 million tonnes of carbon dioxide equivalent — which would put the sector on par with…

A recent paper emphasizes broader strategies for tackling climate change, including addressing CO2 sensitivity, aerosol impacts, and policy measures. It predicts accelerated global warming and underscores the need for political action against environmental degradation driven by financial interests.According to a recent paper in Oxford Open Climate Change, published by Oxford University Press, effective strategies to combat climate change must encompass more than just reducing greenhouse gases. This comes from an analysis…

As more greenhouse gases are released into the atmosphere, it becomes harder and harder for heat to seep into space. This causes the global temperature to rise, and could even result in more greenhouse gases being released. This runaway greenhouse gas effect is a massive danger to planets like Earth, and researchers have finally figured out how it might happen.Understanding the effect that runaway greenhouse gasses can have on our planet is exceptionally important, not only to protect our own home but also to…
