Climate change and the new IPCC 2018 report.

Climate change is a hot topic among different groups of society and has been highly debated in both business and political circles. However, in the scientific literature, there is a strong consensus that global surface temperatures have increased in recent decades and that trend is caused by human-induced emissions of greenhouse gases. For instance, the National Aeronautics and Space Administration (NASA) shows a graph that captures data collected by different research organizations including NASA that shows global temperatures in an upward trend in the past few decades.

According to NASA, multiple studies published in peer-reviewed scientific journals show that 97% or more of actively publishing climate scientists agree that climate-warming trends over the past century are extremely likely due to human activities while at the same time most of the leading scientific organizations worldwide endorse this position. Among these scientific bodies including the U.S. National Academy of Sciences, American Chemical Society, Intergovernmental Panel on Climate Change, etc

Science & Data & Policy Decisions.

The private sector, government, and non-governmental organizations all have one thing in common, that is they rely on data and information to make informed decisions. As such, it is with anticipation that the best science will inform the ways that decision-makers frame issues, consider solutions, decide on programs, and implement outcomes.

The IPCC has published several reports on climate change and today (October 8th, 2018), it released one of its most important ClimateChange reports as it calls it, that requires unprecedented changes in society, which will have huge benefits in reversing the trends of climate warming.

This current IPCC report is a follow-up to the 2015 Paris Agreement on climate change. The Paris agreement was reached at COP21 in Paris on December 12th, 2015 were Parties to the UNFCCC forged the agreement to combat climate change and accelerate and intensify the actions and investments needed for a sustainable low carbon future. The Paris agreement is adopted by about 195 nations.

The new IPCC report calls for “rapid and far-reaching” transitions in land, energy, industry, buildings, transport, and cities.

According to the new IPCC report, through the year 2017, the concentration of greenhouse gases (GHG) emissions in the atmosphere had already warmed the world by one (1) degrees Celsius and it notes that if the average global temperatures rise more than 1.5 degrees Celsius above pre-industrial levels; climate risks to society will increase. These risks include, but not limited to extreme weather, rising sea levels and diminishing Arctic sea ice, etc

Also, the summary for policymakers of IPCC Special Report on Global Warming of 1.5 degrees Celsius approved by governments that were released on October, 8th, 2018 noted that limiting global warming to 1.5 degrees Celsius would require rapid, far-reaching and unprecedented changes in all aspects of society, the IPCC said in a new assessment. With clear benefits to people and natural ecosystems, limiting global warming to 1.5oC compared to 2oC could go hand in hand with ensuring a more sustainable and equitable society.

The new report suggests that Global net human-caused emissions of carbon dioxide (CO2) would need to fall by about 45 percent from 2010 levels by 2030, reaching ‘net zero’ around 2050. This means that any remaining emissions would need to be balanced by removing CO2 from the air.

A shift in energy systems, transport, etc needed to help not exceed 1.5 degrees Celsius: Removal of CO2 from the air is not sustainable. 

However, IPCC scientists suggest that the final last thing needed to help resolve this global issue is political will. The report will be presented to governments at the UN climate change conference in Poland at the end of this year (2018).
