Climate change is reshaping how we think about conservation. Even if fully protected from the ongoing threats imposed by human activities, the ecosystems and biota we have been protecting will not remain the same. Conservation planners must change the way decisions are made because aspects of the environment we have always considered to be relatively constant, including weather patterns, water supply, temperature extremes, even biotic communities, will be changing.
Global warming is a key threat to biodiversity, but few researchers have assessed the magnitude of this threat at the global scale. We used major vegetation types (biomes) as proxies for natural habitats and, based on projected future biome distributions under doubled-CO2 climates, calculated changes in habitat areas and associated extinctions of endemic plant and vertebrate species in biodiversity hotspots.
Carbon Brief has extracted data from around 70 peer-reviewed climate studies to show how global warming is projected to affect the world and its regions. Scroll to see how these impacts vary at different temperature levels, across a range of key metrics. Find specfic categories and regions below.
Climate change is expected to result in range shifts and habitat fragmentation for many species. In the Arctic, loss of sea ice will reduce barriers to dispersal or eliminate movement corridors, resulting in increased connectivity or geographic isolation with sweeping implications for conservation.
As the Earth's climate has changed, Arctic sea ice extent has decreased drastically. It is likely that the late‐summer Arctic will be ice‐free as soon as the 2030s. This loss of sea ice represents one of the most severe positive feedbacks in the climate system, as sunlight that would otherwise be reflected by sea ice is absorbed by open ocean. It is unlikely that CO2 levels and mean temperatures can be decreased in time to prevent this loss, so restoring sea ice artificially is an imperative.
The Community-based Mangrove Rehabilitation Project of the Zoological Society of London ran from 2008 to 2012 with the aim of increasing coastal protection, food resources and livelihood income of coastal communities in Panayand Guimaras by rehabilitating abandoned government-leased fishponds to mangroves, re-establishing legally mandated coastal greenbelts, and securing tenure on coastal land through Community-based Forest Management Agreements (CBFMAs).
This solution aims to create a better governance (shared governance) of natural resources in the coastal zone of Soc Trang Province, Mekong Delta, Vietnam to protect its first line of coastal defense (mangroves) and to improve the livelihood of local communities through resource conservation.
Hoa Binh village - located along the coastline in central Vietnam - is seriously exposed to strong storms, sea encroachment, sand moving, drought and coastline erosion. In addition, the village has approximately 123ha of sandy protection forest areas along a 3.5km coastal stretch. The forest was degraded because of bombing in the war, serious storms and over-harvesting of trees for firewood by local people, making the communities more vulnerable to climate change and extreme weather impacts.
Fertilisers are essential to farming. They provide crops with the nutrients they need to grow.
The severe coral bleaching event in 2010 led to coral mortality in many dive sites of Thailand. This study focused on management strategies for degraded recreational dive sites following the 2010 coral bleaching event in a marine national park in the Andaman Sea. Popular dive sites in marine national parks such as East of Eden and Ao Faiwab in Mu Ko Similan National Park have been temporarily closed since 2010 in order to build resilience and to enhance coral recovery.
