New research maps the global extent of glacial lakes and shows that climate change is causing an increase in the size of these lakes across the planet. As glacial lakes grow, the likelihood of glacial lake outburst floods (GLOFs) in high altitude areas is increasing. This study highlights the urgent need for adaptation planning in high risk mountainous communities that may be exposed to GLOFs as the planet warms.
Climate change is increasing evapotranspiration in the European Alps and causing a decline in surface water supply in the region. Understanding future changes in surface runoff is essential for managing the water supply for over 170 million people.
The United Nations has set a Sustainable Development Goal to end world hunger by 2030. Increasing crop yields is necessary to achieve this goal. However, intensive irrigation practices can also increase the uptake of ozone by plants, damaging sensitive leaf tissues. Lack of ozone pollution mitigation efforts may prevent future progress towards global food security.
