3. PHILIPPINE VULNERABILITIES TO GLOBAL WARMING/ CLIMATE CHANGE
VISITED BY AVERAGE
20 TYPHOONS
EVERY YEAR
With the projected increase in temperature this could mean much stronger and more intense tropical cyclones.
This graph shows the actual tracks of tropical cyclones that entered the PAR during the period A total of tropical cyclones entered the PAR and 56 % of this tropical cyclone reached typhoon intensity. The Northweastern Pacific is the most active tropical basin in the world and any increase in sea surface temperature as a result of climate change will affect future intensity of tropical cyclone. This only shows how the Philippines is vulnerable to climate change. With the projected increase in temperature this could mean stronger and more intense tropical cyclones.
