Markku Kulmala, from the Institute for Atmospheric and Earth System Research, discusses the ACCC Flagship concerning adaptation to climate change, from deep scientific understanding to practical solutions...
International agreements such as the Convention on Biological Diversity (CBD) have committed to conserve, and sustainably and equitably use, biodiversity. The CBD is a vital instrument for global conservation because it guides 195 countries and the European Union in setting priorities and allocating resources, and requires regular reporting on progress. However, the CBD and similar policy agreemen...
Frost damage is among the major limitations to reforestation and forest restoration projects worldwide. Investigations of environmental and genetic effects on frost resistance have focused on boreal and temperate tree species rather than tropical trees. Koa (Acacia koa A. Gray) is a valuable tropical hardwood tree species endemic to the Hawaiian Islands, USA. Koa occurs across a wide elevational g...
Most agree that urgent action needs to be taken to tackle the growing crisis caused by climate change. That is why leaders from 196 countries are meeting in Glasgow in November for a major climate conference, called COP26. But adaptation to climate change also comes at a price - writes Nikolay Barekov, journalist and former MEP....
Abstract The shape of leaf laminae exhibits considerable diversity and complexity that reflects adaptations to environmental factors such as ambient light and precipitation as well as phyletic legacy. Many leaves appear to be elliptical which may represent a ‘default’ developmental condition. However, whether their geometry truly conforms to the ellipse equation (EE), i.e., (...
Seasonal summer rains have done little to offset drought conditions gripping the western United States, with California and Nevada seeing record July heat and moderate-to-exceptional drought according to the National Oceanic and Atmospheric Administration (NOAA). Now, new NASA research is showing how drought in the region is expected to change in the future, providing stakeholders with crucial inf...
The COVID-19 pandemic has increased attention on links between public health and the planet's health-areas traditionally addressed in separate science and policy circles. Now, an international research collaboration conducted the first comprehensive review of urban climate change responses and potential human health improvements....
To promote the sustainability of forest ecosystems and maintain ecosystem services to human populations in the context of climate change, forest managers are considering several adaptation tools. One of those, assisted migration, consists of displacing tree species and/or populations to locations with suitable future climate conditions. Assisted migration plantations, however, could fail to produc...
Silvics of North America (SNA) is a widely used silvicultural manual. However, the last SNA was published in 1990. Therefore, 2,589 registered foresters were surveyed across four US states to answer two broad questions: (1) Should SNA be updated? And (2) would an updated SNA still be a useful tool for forest management? Most respondents indicated that the type and extent of content contained in th...
Climate risk is a consequence of climate hazards, exposure, and the vulnerability (IPCC 2014). Here, we assess future (2040���2049) climate risk for the entire contiguous US at the county level with a novel climate risk index integrating multiple hazards, exposures and vulnerabilities. Future, weather and climate hazards are characterized as frequency of heat wave, cold spells, dryer, and he...
Up to 500 representatives of Ministries responsible for water, environment, foreign affairs and development cooperation, river basin organizations, international and non-governmental organizations and academia from all regions of the world will gather in Geneva and online from 29 September to 1 October 2021 (hybrid format), to discuss transboundary water cooperation, at the ninth session of ...
