Knowledge

Climate change is already altering the distribution of species and the make-up of ecosystems. To be effective, conservation practice must plan for the growing impacts of climate change. IUCN mobilizes research to measure the impacts climate change is having on biodiversity and to identify conservation and mangement solutions. For example, connecting habitats has a key role to play in enabling nature to adapt to the impacts of climate change. Further, ecosystems can store carbon and maintain the critical ecosystem services on which livelihoods depend on.

IUCN expert Commission networks, members, partners and staff use sound scientific expertise in conservation and sustainable natural resource management to produce tools and guidelines on climate change. They work to ensure that political decisions at any level are based on the best available science, and have received inputs from a wide set of relevant stakeholders.

Oceans and climate change

IUCN is working to understand the role of marine ecosystems as carbon sinks and providing goods and services. As a direct consequence of human induced CO2 in the atmosphere, the oceans are undergoing acidification with profound impacts on marine life and our life support system. A new guide, 'Ocean Acidification: Questions Answered', provides the latest science on the speed and scale of impact that CO₂ emissions will have on the ocean and on humanity. Learn more
 

Species and climate change

Which species are most vulnerable to climate change? Which species, ecosystems and regions should we prioritise for conservation? IUCN is developing a tool to systematically assess the vulnerability of species to climate change impacts which is currently being tested and will complement Red List assessments. Learn more

Protected areas and climate change

Protected area systems provide powerful tools to combat climate change. Protected areas can help in two ways: mitigating climate change by sequestering carbon in organic matter and adapting to impacts of climate change by maintaining ecosystem functioning and the services upon which millions of people depend.
