Limiting the global temperature rise to 1.5°C


According to 2019 Statement on the State of the Global Climate, the year 2019 ended with a global average temperature of 1.1 °C above estimated pre-industrial averages, second only to the record set in 2016. Without the role of El Niño in the warming increase observed in 2016, 2019 would have been a record year. The past five years are the five warmest on record, and the past decade, 2010–2019, is also the warmest on record. Since the 1980s, each successive decade has been warmer than any preceding one since 1850.

The Statement on the State of Global Climate outlines the latest science and illustrates the urgency for far-reaching climate action. It brings together data from across the fields of climate science and lists the potential future impacts of climate change – from health and economic consequences to decreased food security and increased displacement.

Since 2015, the Philippines, together with other nations, aims to strengthen the global response to the threat of climate change by pursuing efforts to limit the global temperature increase even further to 1.5 degrees Celsius – through the Paris Agreement.

But the report reflects that in 2019, the global atmospheric mole fractions of greenhouse gases continues to rise, the sea-ice extent in Arctic and Antarctic remains low, the ocean-heat content reached record-high levels again, and the global mean sea level rise has reached its highest value. The results of this report demonstrate that climate change is already very visible in various ways. More ambitious climate mitigation efforts are needed to keep the warming below 2 °C by the end of the century.

1.5°C limit can only be achieved with an unchanging collective resolve for immediate and drastic action at global and local levels as called for by the Paris Agreement.
