It's not too late to mitigate global warming.
The climate crisis is not a distant threat; it's happening right now and affecting what matters most to us. Hurricanes intensified by a warming planet and drought-fueled wildfires are destroying our communities.
Rising seas and flooding are swallowing our homes. And record-breaking heatwaves are reshaping our way of life. The good news is we know how to turn the tide and avoid the worst possible outcomes. However, understanding what needs to be done can be confusing due to a constant stream of climate updates, scientific findings, and critical decisions that are shaping our future. That's why the ABC News Climate and Weather Unit is cutting through the noise by curating what you need to know to keep the people and places you care about safe. We are dedicated to providing clarity amid the chaos, giving you the facts and insights necessary to navigate the climate realities of today -- and tomorrow.EPA cancels toxic pesticide used in growing produce The United States Environmental Protection Agency said it's canceling any product containing the pesticide dimethyl tetrachloroterephthalate , also known as Dacthal. Migrant farm workers harvest broccoli in a field at a farm in Stouffville, Ontario, Canada, Sept. 22, 2024.According to the EPA, their decision is based on comprehensive scientific studies that indicate potential thyroid toxicity linked to DCPA. The agency says research suggests that exposure to this pesticide during pregnancy can lead to changes in thyroid hormone levels in unborn children. Studies cited by the EPA indicate that these hormonal changes could be associated with various health concerns, including low birth weight, impaired brain development and reduced IQ. That research suggests that these developmental challenges may also have long-term effects on motor skills. DCPA is used in the industrial farming of broccoli, Brussels sprouts, cabbage and onions. While pregnant women working in agriculture are most at risk, pesticides can travel into neighboring communities via the air and runoff, putting non-agricultural workers at risk as well. In a press release, EPA's assistant administrator for the office of chemical safety and pollution prevention, Michal Freedhoff, wrote, "With the final cancellation of DCPA, we're taking a definitive step to protect pregnant women and their unborn babies. The science showing the potential for irreversible harm to unborn babies' developing brains, in addition to other lifelong consequences from exposure, demands decisive action to remove this dangerous chemical from the marketplace," Freedhoff added.The number of billion-dollar weather and climate disasters in the United States keeps growing. The National Oceanic and Atmospheric Administration has added Hurricanes Debby, Helene and Milton to their official 2024A drone view shows a bulldozer removing debris from a road after Hurricane Milton made landfall in Matlacha, Fla., Oct. 10, 2024.This brings the year-to-date total for billion-dollar disasters to 24 unique events. That's the second-highest total for the same period, only eclipsed by 2023, when there were 27 billion-dollar disasters in the same time frame. The final damage costs for Hurricane Helene and Milton are still being determined, but NOAA says they will both surpass the billion-dollar threshold.. According to NOAA, tropical cyclones cause more damage than any other kind of weather disaster, with over $1.3 trillion in damages since 1980.UN says it will take 'a quantum leap in ambition' to avoid climate disaster The United Nations is calling out the world's largest polluting nations for failing to take decisive action in their efforts to reduce greenhouse gas emissions significantly. And they're warning that it will require nothing short of "a quantum leap in ambition" if we are to avoid the worst-case global warming scenarios.According to the United Nations Environment Programme's Emissions Gap Report 2024, aptly titled, "No more hot air … please!" the world has made little progress in reversing the use of fossil fuels and faces twice as much warming as agreed to during the Paris Climate Agreement. The report finds that unless we significantly reduce our global emissions and do so quickly, the planet is headed toward a 3.1° C increase in warming above pre-industrial levels by 2100. The annual report looks at countries' emission reduction promises and where we are in meeting those goals. The report said that despite the urgent need to reduce GHG emissions, global emissions actually set a new record in 2023, increasing by 1.3%. However, the report made a point to emphasize that the majority of global emissions are coming from G20 countries, specifically China, the United States and India. Only the U.S. showed a slight reduction in emissions in 2023, down 1.4%. China and India saw an increase of 5.2% and 6.1% respectively. Both countries produce many of the products purchased and used by American consumers, and some experts say their emissions are our emissions. In 2015, during a summit in Paris, the majority of the world's governments agreed to work toward limiting global warming to 1.5° C . This new report said it would require a 42% cut in yearly GHG emissions by 2030 if we want to try to avoid surpassing that milestone. World leaders will meet in Azerbaijan next month for the UN climate summit COP29 to work on meeting the goals first agreed to in Paris.The Northeast and Mid-Atlantic regions are experiencing an unprecedented dry spell, raising concerns of fire danger. Central Park in New York City is also facing an unusually dry October. The world-renowned landmark has seen zero rainfall this month. Since record-keeping began in 1869, there has never been a month in Central Park that didn't have some rainfall. With no rain in the forecast through the end of the month, this could be a first.Similarly, Philadelphia is on the brink of shattering its record for the longest period without rain, reaching 25 days as of Oct. 24. If the city doesn't receive any precipitation by the end of Monday, Oct. 28, it will surpass an historic 29-day dry streak, the current record. Records go back to 1871. As a result of these near-record dry conditions, fire danger levels have surged. Elevated warnings stretch from Massachusetts to Virginia, with humidity levels plummeting to around 30% and gusty winds of nearly 30 mph. New Jersey is particularly vulnerable, with most of the state under a Red Flag Warning, indicating a high threat of wildfires. The combination of low moisture and wind creates an environment ripe for the spread of any fire, making it crucial for residents to remain vigilant.
