The high-impact weather in the second half of April underlines yet again the vulnerability of society to weather, water and climate-related hazards and the need for Early Warnings For All.The waning El Niño event, alongside a phenomenon known as the Indian Ocean Dipole, is playing a role, notably in the floods in East Africa and drought in Southern Afri…
The extreme rainfall event was associated with a low-pressure system, initially originating from mid latitude Eastern Europe, that induced violent storms, also bringing heavy rainfall to other parts of Asia. In Dubai, most of the rain fell on Monday 15th of April and exceeded all previous records of daily rainfall in the last 75 years, when r…
There is likely to be a significant increase in the danger of wildfires through the 21st century. Indeed, the expectation is that by 2100 the danger will be high even in regions where it is very low today. Those are the findings of a study by Julia Miller, a PhD student in the Hydrology & Climate Impacts in Mountain Regions research group…
Stretching across seven Central and Eastern European countries, the Carpathian mountain range is home to some of the continent's largest intact forests. It boasts nearly 4,000 plant species, as well as large populations of brown bears and grey wolves.In 2003, the Carpathian Convention was established, bringing together the Czech Republic, Hungary, Polan…
“Natural disasters have always been part of human history, but the frequency and intensity of natural disasters have been accelerated by climate change, and in the wake of that, we’re finding exaggerated mental health symptoms,” says Jyoti Mishra, PhD ’08, MBA ’22, associate professor in the Department of Psychiatry at UC San Diego School of Medicine.We…
With climate adaptation set to be a major topic at Cop28, UNEP has published a new policy brief to better inform climate adaptation planning and implementation. The new policy brief summarises lessons and best practices from 23 different National Adaptation Plans that UNEP is supporting around the world. The brief focuses particularly on…
The past year has seen vulnerable communities across the globe experience numerous water-related disasters that have either threatened or completely decimated lives and livelihoods. Countries in the Global South are exposed to this type of disaster, with their vulnerability often directly related to both the short- and long-term effects of the clim…
Firefighters light and carefully monitor prescribed burns with the aim of preventing large wildfires. But climate change may narrow the window of opportunity for these prevention efforts, according to a new study published in Communications Earth and Environment.The study’s authors used historical and projected trends to forecast future weather conditio…
Sub-Saharan African countries strongly rely on the agricultural and forestry sectors. Agriculture contributes up to 60% of some countries’ gross domestic product. But the sector is highly vulnerable to climate change because it relies heavily on climatic factors. This vulnerability is particularly marked in the region because of its slow rate of te…
[...]Writing in the Science Advances journal in 2018, climatologists Carlos Nobre and Thomas Lovejoy used the phrase "tipping point" to refer to the possible impact of environmental destruction in the Amazon, especially deforestation, climate change and fires.Their influential article estimated that between 20% and 25% of the Amazon forest must be kept…
[...]Dengue fever is a climate-sensitive disease that is spread through the saliva of an infected female Aedes mosquito when it bites an uninfected person. Dengue fever presents with high fever, severe headache, flu-like symptoms, intense joint and muscle pain, and other flu-like symptoms. It is usually a mild disease that can be adequately treated with…
During May and June 2023 Canada witnessed exceptionally extreme fire-weather conditions, leading to extensive wildfires that burned over 13 million hectares.Extreme wildfire conditions in Canada have been fueled by intense, spatially extensive and persistent fire-conducive weather conditions, known as fire weather, which has been observed since the begi…
The planet experienced the hottest day on record earlier this month and climate projections estimate the intensity of heat waves and poor air quality will increase and continue to cause severe impacts. Researchers from the University of Waterloo and Toronto Metropolitan University have refined and expanded a method of data collection to assess their hea…
