Extreme rain and snowfall precipitation exacerbated by humans

Man-made climate change has been influencing extreme rain and precipitation events for decades, according to new research using machine learning. Climate models have long predicted that extreme precipitation (rain, snow or hail that dramatically exceeds normal levels) will happen more often as anthropogenic climate change advances. But this new study, published today in Nature Communications, … Continue reading Extreme rain and snowfall precipitation exacerbated by humans

What’s the difference between climate and weather?

One of the first things I get asked when I talk to school students is: “What’s the difference between weather and climate?” The answer – that climate is the statistics of the weather – doesn’t bring a lot of excitement to the classroom, so I use an analogy from a friend at the Bureau of … Continue reading What’s the difference between climate and weather?

Fire and rain and the smoke that lingers

Wildfire-driven thunderstorms, such as those created in Australia a year ago, produce lingering impacts that may affect much of the globe, scientists have told the virtual annual meeting of the American Geophysical Union. Such storms occur when fires funnel hot air upward, much like a massive chimney, says David Peterson, a meteorologist at the US … Continue reading Fire and rain and the smoke that lingers

Future hurricanes may cause havoc inland

North Atlantic hurricanes are weakening more slowly than they used to when they hit land, according to a new study in the journal Nature, and it’s linked to climate change. Japanese researchers say those that develop over warmer oceans carry more moisture and therefore stay stronger for longer. There is thus a real risk than … Continue reading Future hurricanes may cause havoc inland

We need better weather warnings

More than 11,000 disasters have been attributed to weather, climate and water-related hazards over the past half century, involving two million deaths, yet one in three people around the world are still not adequately covered by early warning systems. That is one of the key findings of the 2020 State of Climate Services multi-agency report … Continue reading We need better weather warnings

Last five years confirmed as warmest on record

The World Meteorological Organisation published a definitive climate report card showing concentrations of greenhouse gases continue to rise, and the last five years were the warmest on record. The Statement on the State of the Global Climate also confirmed that the ongoing drought and recent bushfires in Australia were a globally significant climate event. The report is … Continue reading Last five years confirmed as warmest on record
