Temperate Rainforests Face Severe Climate Threats

 





Recent research marks that over 68 percent of these ecosystems could vanish by 2100 if current greenhouse gas emissions continue, which is termed ‘business-as-usual.’ Temperate rainforests are unique and vital, yet they occupy less than one percent of the Earth’s land surface

Importance of Temperate Rainforests

These forests support diverse species and store substantial carbon, which is crucial for mitigating climate change impacts. Their unique ecosystems are found in specific regions, including parts of Canada, the US, Chile, Japan, Australia, New Zealand, and the UK

Historical Context and Current Status

Approximately 43 percent of temperate rainforests have already been lost due to deforestation. Only 37 percent of primary old-growth forests remain. Regions like Europe have seen nearly complete loss of these ecosystems.

Vulnerability to Climate Change

Temperate rainforests thrive in cool, moist climates. Rising summer temperatures threaten their survival. The research warns that unmitigated climate change could lead to disaster for these forests globally.

Need for Protection and Restoration



The study stresses the urgent need for conservation efforts. Protection and restoration of temperate rainforests are critical. This includes addressing ongoing degradation and safeguarding remaining forest areas.




The research may underestimate the impacts of climate change. It does not fully account for extreme weather events like landslides and heatwaves. These factors could further accelerate the decline of temperate rainforests.

The Role of Microclimates

Intact forests typically create cooler microclimates, which can mitigate warming impacts. However, fragmented forests are more susceptible to temperature increases.

Isolated and edge forests are particularly vulnerable. Maintaining intact forest ecosystems is essential for their resilience against climate change. The future of temperate rainforests hinges on immediate and effective conservation strategies.
