Climate scenarios are commonly required in climate change impact, vulnerability and adaptation assessments to provide alternative views of future conditions considered likely to affect society, systems and sectors, including a quantification of climate risks, challenges and opportunities.
Climate Change in the Philippine Context. As an archipelago in the Pacific, the Philippines experiences the effects of climate change through extreme weather events such as typhoons reaching the (highest) Category 5 intensity on the Saffir–Simpson Hurricane Scale or “supertyphoons’’.
Climate change is having serious impacts in the Philippines such as increased frequency and severity of natural disasters, sea level rise, extreme rainfall, resource shortages, and environmental degradation. [1] .
The observed temperature in the Philippines has increased by 0.68°C over the past 65 years (1951-2015); warming at an average rate of 0.1°C per decade. The average temperature in all areas in the Philippines is expected to continue to rise by as much as 0.9°C to 1.9°C (under RCP 4.5) and 1.2°C to 2.3°C (under RCP8.5) by mid-21st century.
Impacts of climate change in the Philippines are immense, including: annual losses in GDP, changes in rainfall patterns and distribution, droughts, threats to biodiversity and food security, sea level rise, public health risks, and endangerment of vulnerable groups such as women and indigenous people.
