2018 Was The 4th Hottest Year on Record

The results are in… 2018 was the fourth hottest year on record for the globe. According to the National Oceanic and Atmospheric Administration (NOAA), “This marks the 42nd consecutive year (since 1977) with an above-average global temperature. Nine of the 10 warmest years have occurred since 2005, with the last five years comprising the five hottest.”

This trend is the result of global warming from burning fossil fuels such as oil, gas, and coal.

According to NASA GISS Director Gavin Schmidt, “The impacts of long-term global warming are already being felt — in coastal flooding, heat waves, intense precipitation and ecosystem change.”

This statement is consistent with the findings of the National Climate Assessment released late last year, which stated that “Earth’s climate is now changing faster than at any point in the history of modern civilization, primarily as a result of human activities. The impacts of global climate change are already being felt in the United States and are projected to intensify in the future— but the severity of future impacts will depend largely on actions taken to reduce greenhouse gas emissions and to adapt to the changes that will occur.”

The warming has gotten faster too. The National Oceanic and Atmospheric Administration (NOAA) found that land and ocean warming since 1981 has been more than twice as fast as the overall average, including the late 19th- and early-mid 20th century. While new global high temperature records were set about every 13 years during the span of 1880-1980, since 1981, new global high temperature records have been set every 3 years on average.

In the United States, 2018 was the 14th warmest year on record and had 14 separate billion-dollar weather and climate disasters. In total, these hurricanes, wildfires, and other storms killed at least 247 people and caused $91 billion in damages. In the Southeast, the most notable weather and climate disasters of 2018 were Hurricanes Michael and Florence, which caused $25 and $24 billion in damages, respectively. Hurricanes and wildfires are made worse by global warming.

To avoid the worst impacts of climate change, we must quickly phase out fossil fuels and transition to a clean energy economy. This will mean continued progress in both the power and transportation sectors. The Southeast has made strides toward this end in recent years (for instance with dramatic growth in solar power), yet this progress represents just a fraction of what needs to be done in the coming years. The International Panel of Climate Change report published last fall stated that in order to limit global warming to 1.5 degrees Celsius, global carbon pollution will need to be reduced by about 45 percent from 2010 levels by 2030, and reach ‘net zero’ around 2050.

SACE continues to fight for clean energy solutions that will help usher in this new clean energy economy, leading to a more prosperous economy, sustainable environment, and higher quality of life for generations now and into the future.
