The Paris Agreement survived the U.S. withdrawal and standardized net zero, but emissions continue to rise and vulnerable people suffer from climate disasters In order to limit the increase in global temperature to a level well below 2 degrees Celsius and as close as possible to 1.5 degrees Celsius above pre-industrial levels, it is essential that companies , policy makers and civil society are pursuing comprehensive actions to combat climate change in the short and long term, in line with the goals of the Paris Agreement on climate change. The agreement commits all countries to reduce their emissions and cooperate to adapt to the effects of climate change and calls on countries to strengthen their commitments over time. The agreement provides developed countries with a means to assist developing countries in their mitigation and adaptation efforts, while establishing a framework for monitoring and reporting transparently on developing countries` climate goals. The early stages of implementing these agreements have further watered down ambitions, while ICAO has harassed climate critics on social media. In light of the above, 179 countries and the EU spent two weeks in Paris in December 2015 to draft the final text of an agreement to keep global temperature rise well below 2 degrees Celsius and, if possible, below 1.5 degrees Celsius. Hansen and Lebedeff`s (1987) graph shows almost the same high temperature peak in the 1930s and 1940s as the oldest Graph of the National Academy of Sciences, published in 1975 (NAS 1975). In the new GISS-2008 and GISS-2017 temperature datasets from the NASA Goddard Institute for Space Studies (GISS, 2008; GISS, 2017), this summit has all but disappeared. The decades from 1910 to 1940 in GISS-2017 were 0.05 to 0.1 degrees Celsius colder than in GISS-2008. Satellite temperature measurements (UAH, 2017) have been virtually non-existent since 2000.
The UAH temperature data begin in 1979 and were compensated at the same level as the GISS-2017 in 1979. The continued warming of GISS-2017 in the 2010s appears to be about 0.2oC above the UAH temperature. Climate change is one of the greatest challenges facing the world today. It is responsible for the increase in extreme weather events, as well as an uninterrupted series of record-breaking warmest years. Environmental concerns and the threat of climate change over the past decade have been a consistent feature of the World Economic Forum`s global risk report. Perhaps the strangest development since the Paris agreement is China, which has pledged in Paris to end the annual growth of its climate-changing pollution rates by 2030.
