Climate change in the current global scenario
2019 was the second hottest year on record, at only 0.04 °C below the 2016 record, with a global average temperature of over 1.1°C above the average since the late 19th century. In addition, the decade that just ended was the warmest in history. Against this backdrop, fossil fuels represent the main driver of global warming. Already in 2018, the Intergovernmental Panel on Climate Change (IPCC) had pleaded with the international community to respect the limit of 1.5°C—the key threshold outlined in the Paris agreement on climate change beyond which global warming would cause devastating consequences for natural ecosystems and humanity.
The IPCC says that the next decade will be decisive in limiting global warming, however, despite this warning, the most recent reports on climate change point to a critical scenario when it comes to global warming. Just consider that, according to the latest estimates, the current scenario will bring Earth towards a temperature increase of 3 to 5 °C by the end of the century.
