National Weather Forecast

On the last day of 2023, a clipper system will be moving through the Great Lakes, leading to rain and snow chances in the region. A system over the Pacific near California will lead to rain and higher-elevation snow. Some scattered rain and snow will be possible in the Northwest, with some rain showers in Louisiana.

An inch or two of rain could fall across portions of California through Monday evening.

A few inches of snow is expected to fall in the Great Lakes, Northeast, Appalachian Mountains, and the Sierra through Monday evening.

Meanwhile, for the Ball Drop in Times Square Sunday evening, quiet conditions are expected with temperatures hovering around 40F.

Earth Was Due for Another Year of Record Warmth. But This Warm?

More from the New York Times: “Earth is finishing up its warmest year in the past 174 years, and very likely the past 125,000. Unyielding heat waves broiled Phoenix and Argentina. Wildfires raged across Canada. Flooding in Libya killed thousands. Wintertime ice cover in the dark seas around Antarctica was at unprecedented lows. This year’s global temperatures did not just beat prior records. They left them in the dust. From June through November, the mercury spent month after month soaring off the charts. December’s temperatures have largely remained above normal: Much of the Northeastern United States is expecting springlike conditions this week.”

Scientists uncover link between the ocean’s weather and global climate

More from the University of Rochester: “An international team of scientists has found the first direct evidence linking seemingly random weather systems in the ocean with climate on a global scale. Led by Hussein Aluie, an associate professor in the University of Rochester’s Department of Mechanical Engineering and staff scientist at the University’s Laboratory for Laser Energetics, the team reported their findings in Science Advances. The ocean has weather patterns like what we experience on land, but on different time and length scales, says lead author Benjamin Storer, a research associate in Aluie’s Turbulence and Complex Flow Group. A weather pattern on land might last a few days and be about 500 kilometers wide, while oceanic weather patterns such as swirling eddies last three to four weeks but are about one-fifth the size.”

Low economic growth can help keep climate change within the 1.5°C threshold

More from the Universitat Autonoma de Barcelona: “A recent study by the Institute for Environmental Science and Technology of the Universitat Autònoma de Barcelona (ICTA-UAB) shows that pursuing higher economic growth may jeopardise the Paris goals and leave no viable pathways for humanity to stabilise the climate. On the contrary, slower growth rates make it more feasible to achieve the Paris goals. The scientific study, published recently in the journal One Earth, was conducted in collaboration with researchers from the University of Barcelona, the University of Leeds, and the London School of Economics and Political Science (LSE), and led by Aljoša Slameršak, Giorgos Kallis, Daniel W. O’Neill, and Jason Hickel. The article focuses on the period between 2023 and 2030, crucial for keeping the goals of the Paris Agreement alive and challenges the established assumption of high economic growth in existing scenarios of climate mitigation, since growth itself is a major driver of greenhouse gas emissions.”
