Attribution science has led to major advances in linking the impacts of extreme weather and human-induced climate change, but large gaps in the published research still conceal the full extent of climate change damage, warns a new study released today in the first issue of Environmental Research: Climate, a new academic journal published by IOP Publishing.
Extreme dry conditions contributed to the decline of the ancient South Arabian kingdom of Himyar.
Climate change gives rise to more unstable weather, local droughts and extreme temperature records, but a coherent theory relating local and global climate is still under active development.
Certain rootstocks may improve plant performance by enhancing the amount of root biomass used to support shoot function
Plants — they’re just like us, with unique techniques for handling stress.
Humanity is “at a crossroads” when it comes to managing drought and accelerating mitigation must be done “urgently, using every tool we can,” says a new report from the United Nations Convention to Combat Desertification (UNCCD).
The lake level of the Dead Sea is currently dropping by more than one metre every year - mainly because of the heavy water consumption in the catchment area.
Drought and the potential increase in the number of droughts worldwide due to climate change remains a concern for scientists. A recent study led by Stony Brook University researchers suggests that human migration due to droughts will increase by at least 200 percent as we move through the 21st Century.
A new UC Riverside study shows it’s not how much extra water you give your plants, but when you give it that counts.
Spatially isolated “hot spots” and brief “hot moments” shape methane emissions from tropical forest soils. In this research, scientists used model simulation to understand how microbes and soil variables contribute to the soil’s methane production and consumption. The models indicate that drought alters the diffusion of oxygen and microbes into and out of soil, leading to increased methane release from the entire hillslope during drought recovery. This finding is important for understanding sources of methane, an important greenhouse gas.
Partnerships between water utilities, irrigation districts and other stakeholders in California will play a critical role in funding new infrastructure under the Water Resilience Portfolio Initiative announced in 2020 by Gov. Gavin Newsom, but a new study warns that benefits might not be evenly distributed without proper structure to the agreements.
A new study, “Global field observations of tree die-off reveal hotter-drought fingerprint for Earth’s forests,” compiled a global database of the published locations of climate-induced forest die-off events, from 1970-2018, across 675 locations. After analyzing the climate conditions at each location during each event, researchers found a common ‘hotter-drought fingerprint’ for Earth’s forests, a term that describes the combination of higher temperatures and more frequent droughts for a lethal set of climate conditions.
Record-breaking Victorian weather has been revealed after millions of archived rainfall records dating back nearly 200 years were rescued by thousands of volunteers during the first Covid-19 lockdown.
New research, led by Dr Petra Holden from the African Climate and Development Initiative (ACDI) at the University of Cape Town (UCT), has shown how catchment restoration – through the management of alien tree infestation in the mountains of the southwestern Cape – could have lessened the impact of climate change on low river flows during the Cape Town “Day Zero” drought.
Droughts occurring at the same time across different regions of the planet could place an unprecedented strain on the global agricultural system and threaten the water security of millions of people, according to a new study in Nature Climate Change.
Scientists have long hypothesized that climate change, by intensifying stressors like drought or wildfires, would make an ecosystem more vulnerable to invasive plants. Those invasive plants may in turn alter the environment in ways that amplify the impacts of climate change, explained Luke Flory, a professor of ecology in the UF/IFAS agronomy department. A new long-term field study conducted by Flory’s lab offers the first experimental evidence to support this hypothesis.
Two Clemson University civil engineers said their newly published research is the most comprehensive analysis so far of what causes flash drought, a weather phenomenon that has been blamed for billions of dollars in crop damage and increased wildfire risk.
