Fig. 1. Left: monthly global temperature anomalies. Right: Nino 3.4 temperature anomaly for past six years and 8 months, and NCEP forecast (green line). By Dr James Hansen and Dr Makiko Sato First the good news: NOAA’s newest prediction for the tropics has a deeper La Nina (Fig. 1, Right), which should keep global temperature […]
The United Nations warned Friday that the planet is barreling toward 2.7°C of warming by the end of the century, a nightmare scenario that can be averted only if policymakers take immediate and sweeping action to slash greenhouse gas emissions. By Jake Johnson Common Dreams Even if the 191 parties to the Paris climate accord meet their current […]
For many in the United States, the first sign of fall is the start of football season. College students are back on campus and broadcasting networks are gearing up for the usual Thursday-to-Monday coverage. But the impacts of climate change have undeniably worsened in recent years, converging in a cluster of disasters each summer and […]
People’s views about climate change, from how worried they are about it affecting them to how willing they are to do something about it, have shifted in developed countries around the world in recent years, a new survey by the Pew Research Center finds. Kate T. Luong, George Mason University; Ed Maibach, George Mason University, […]
Canadian voters concerned about the environment and climate change find themselves presented with a series of dilemmas with the Sept. 20 election almost upon us. By Mark Winfield, York University, Canada The Conversation The environment is often a forgotten issue once politicians are on the campaign trail. But this time, propelled by the catastrophic wildfires […]
Record downpours from Hurricane Ida overwhelmed cities across the Northeast on Sept. 1, 2021, hitting some with more than 3 inches of rain an hour. Water poured into subway stations in New York City, and streets flooded up to the rooftops of cars in Philadelphia. The storm had already wreaked havoc on the Gulf Coast […]
Sixteen years to the day that Hurricane Katrina made landfall, Hurricane Ida struck at Port Fourchon, La., on Aug. 29, as a Category 4 hurricane with 240 kilometres per hour winds. Given the date and location of the area affected, Katrina and Ida comparisons are being made. By Jack L. Rozdilsky, York University, Canada The […]
Historically excluded racial and ethnic groups, along with low-income and less educated populations will likely face greater harm from the impacts of climate change, an EPA report detailed Thursday. The study comes at the end of a week dominated by devastating climate impacts across the country. By Nathan Kauffman Nexus Media NewsUnder a scenario in […]
For many years, federal, state and corporate proponents of building more dams in California have touted cold water river releases provided by increased water storage behind dams as a key tool in “saving” struggling salmon and steelhead populations. Yet a just published study by the UC Davis Center for Watershed Sciences, Dams Ineffective for Cold-Water Conservation – 8/25/21, has found […]
Bolstering the case for meaningful climate action, a major report released Wednesday found that Earth’s atmospheric greenhouse gas concentrations and sea levels both hit record highs in 2020. By Kenny Stancil Common Dreams Based on the contributions of more than 530 scientists from over 60 countries and compiled by the U.S. National Oceanic and Atmospheric Administration […]
By Kevin Trenberth, National Center for Atmospheric Research The Conversation Climate change has been accumulating slowly but relentlessly for decades. The changes might sound small when you hear about them – another tenth of a degree warmer, another centimeter of sea level rise – but seemingly small changes can have big effects on the world […]
The approach of summer in the U.S. means that it’s time to be ready for hurricanes and wildfires. The incidence of weather and climate disasters is increasing in the U.S., a trend due partly to climate change but also to human decisions. By Erik Salna, Florida International University The Conversation Since the 1950s, population growth […]
The U.S. government announced its first-ever water shortage declaration for the Colorado River on Aug. 16, 2021, triggering future cuts in the amount of water states will be allowed to draw from the river. The Tier 1 shortage declaration followed the U.S. Bureau of Reclamation’s forecast that the water in Lake Mead – the largest reservoir in the U.S., […]
The United Nations’ Intergovernmental Panel on Climate Change (IPCC) has published the first part of its sixth assessment report (AR6), which will form the cornerstone of climate science for the years ahead. Summarizing the “physical science basis” for climate change, the report pulls together the findings from more than 14,000 peer-reviewed studies. By Simon Evans, Josh Gabbatiss, Zeke […]
July global temperature (+1.16°C relative to 1880-1920 mean) was within a hair (0.02°C) of being the warmest July in the era of instrumental measurements (Fig. 1, left). That’s remarkable because we are still under the influence of a fairly strong La Nina (Fig. 1, right). Global cooling associated with La Ninas peaks five months after the […]
