Climate change: threats and challenges

Summary:
From Maria Alejandra Madi Global warming and global CO2 emissions are interconnected. In 2018, heatwaves were observed in Europe, Asia, North America and northern Africa, while the extent of Arctic sea ice has been continuously dropping. According to the World Meteorological Organization (WMO), the last four years (2015-2018) have been the warmest years on record. In particular, between January and October 2018, global average temperature increased 0.98 degrees Celsius above the levels of 1850-1900. If this trend continues, temperatures may rise by 3-5 degrees Celsius by 2100. Global CO2 emissions have also been increasing in the last years. China and the US together account for more than 40% of the global total CO2 emissions, according to 2017 data from the European Commission’s Joint

Global warming and global CO2 emissions are interconnected. In 2018, heatwaves were observed in Europe, Asia, North America and northern Africa, while the extent of Arctic sea ice has been continuously dropping. According to the World Meteorological Organization (WMO), the last four years (2015-2018) have been the warmest years on record. In particular, between January and October 2018, global average temperature increased 0.98 degrees Celsius above the levels of 1850-1900. If this trend continues, temperatures may rise by 3-5 degrees Celsius by 2100.

Global CO2 emissions have also been increasing in the last years. China and the US together account for more than 40% of the global total CO2 emissions, according to 2017 data from the European Commission’s Joint Research Centre and the PBL Netherlands Environmental Assessment Agency. After the withdrawal from the Paris climate change agreement, the US’s environmental policy shifted to a pro-fossil fuels agenda on behalf of the need to overcome the disadvantage of American businesses and workers. Trump called climate change a “very, very expensive form of tax”. Fossil fuel lobbies in Saudi Arabia, Russia and Canada are powerful forces against government climate policies.  read more
