Due to its geographical location, climate, and topography, the Philippines is ranked third on the World Risk Index for highest disaster risk and exposure to natural disasters. [20] 16 of its provinces, including Manila, Benguet, and Batanes, are included in the top 50 most vulnerable places in Southeast Asia, with Manila being ranked 7th. [21]
According to the UN Office for the Coordination of Humanitarian Affairs (OCHA), the Philippines is one of the most disaster-prone countries in the world. [15] The archipelago is situated along the Pacific Ocean's typhoon belt, leaving the country vulnerable to around 20 typhoons each year, a quarter of which are destructive. [ 16 ]
A sign on South Tarawa, Kiribati pointing out the threat of sea level rise to the island, with its highest point being only three metres above sea level.. The effects of climate change on small island countries are affecting people in coastal areas through sea level rise, increasing heavy rain events, tropical cyclones and storm surges.
Some climate change effects: wildfire caused by heat and dryness, bleached coral caused by ocean acidification and heating, environmental migration caused by desertification, and coastal flooding caused by storms and sea level rise. Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an overall ...
Severe impacts are expected in South-East Asia and sub-Saharan Africa, where most of the local inhabitants are dependent upon natural and agricultural resources. [250] [251] Heat stress can prevent outdoor labourers from working. If warming reaches 4 °C then labour capacity in those regions could be reduced by 30 to 50%. [252]
Probability of 20-year, 50-year and 100-year extremes consistently increases with warming across Asia - up to a 7-fold average increase for 100-year extremes under 3 °C (5.4 °F) of warming. [ 13 ] Precipitation trends are more complex than temperature trends.
Elevation factors significantly in the variation of temperature in the Philippines. In Baguio, with an elevation of 1,500 m (4,900 ft) above sea level, the mean average is 18.3 °C (64.9 °F) or cooler by about 4.3 °C (8 °F).
The first chapter describes the expected effects of climate change with one degree Celsius (1 °C) increase in average global temperature since pre-industrial times.. The second chapter describes the effects of two degrees average temperature and so forth until Chapter 6 which shows the expected effects of an increase of six Celsius degrees (6 °C) average global temperature.
