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 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 Philippines Country Climate and Development Report (CCDR) comprehensively analyzes how climate change will affect the country's ability to meet its development goals and pursue green, resilient, and inclusive development. The CCDR helps identify opportunities for climate action by both the public and private sectors.

The Philippines is highly vulnerable to the adverse impacts of climate change, which increase the frequency and intensity of heat-waves, floods, droughts, typhoons; alter agricultural and coastal and marine ecosystem output and productivity; reduce water availability and quality; and increase the incidence of climate-sensitive infectious diseases.

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.

In 2022 and 2023, the World Risk Index ranked the Philippines as the country with the highest disaster risk. The Philippines’ rich but increasingly depleted natural resources provide critical protection against the impacts of climate change, offering shoreline protection, flood control, soil stability, and habitats for biodiversity.

The Philippines is highly vulnerable to the impacts of climate change. Rising sea levels, higher temperatures, and increased frequency of typhoons and extreme weather events can cause floods, landslides, and erosion that pollute water resources, damage infrastructure, destroy crops, and lead to loss of lives and livelihoods.

The Philippine Climate Change Assessment (PhilCCA) prepared by Oscar M Lopez Center (OMLC) in partnership with the Climate Change Commission (CCC) is a three-volume report synthesizing “scientific information from international and local literature to provide an assessment of climate change for the Philippines and identify gaps in the ...

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-21 st century.

In 2021, the National Panel of Technical Experts (NPTE) identified the top ten (10) climate-induced risks being faced by the Philippines, namely: (a) sea level rise, (b) coastal erosion, (c) flooding, (d) increase in frequency and severity of tropical cyclones, (e) extreme drought, (f) temperature increase and rising urban heat index, (g) extrem...
