sobering

The world’s economies including its energy markets have been in turmoil in recent times but despite the chaotic conditions, the shift to clean energy is gaining momentum. This year, for the first time, the world is investing more in wind and solar power than in oil and gas drilling. Investments in renewables are expected to reach $494 billion this year, more than the $446 billion directed towards oil and gas extraction. It is rather sobering to realize that the world is still spending nearly half a trillion dollars a year to dig up more oil and gas.

According to the International Energy Agency, there will be an estimated 340 gigawatts of new renewable power capacity installed in 2022. This is roughly equal to the total installed power capacity of Japan, which has the world’s third-largest economy. This year is also seeing tremendous growth in electric cars, which are projected to make up 13% of all light-duty vehicle sales across the globe.

According to analysis by Bloomberg Green, 87 countries are now getting at least 5% of their power from wind and solar. This number is considered to be a critical tipping point at which emerging technologies become more widely adopted. The United States reached that 5% threshold in 2011. Last year, our country surpassed 20% solar and wind power. If we follow trends set by pioneering countries like Denmark, Ireland, and others, wind and solar will supply at least half of our power within the next decade.

Despite the turbulence in global energy markets, the shift to clean power is ongoing. Estimates are that global spending on renewables will double over the next 10 years.

Despite Turmoil in Energy Markets, the Shift to Clean Energy Is Gaining Steam

The federal government has issued the annual State of the Climate report and it is a sobering one. The report states that carbon dioxide in the atmosphere rose to levels the world has not seen in at least 800,000 years. Global carbon dioxide concentrations reached a record 407.4 parts per million during 2018. That is 2.4 ppm more than 2017.

Other greenhouse gases like methane and nitrous oxide also continued their rapid increase. Taken together, the global warming power of greenhouse gases was 43% stronger than it was in 1990.

Along with greenhouse gases, global sea levels also reached their highest levels on record for the seventh consecutive year. Ocean levels are rising about an inch per decade, but that number may rise if ice melt at the poles continues to accelerate.

Global temperatures had their fourth highest level on record in 2018, slightly lagging 2016, 2015, and 2017 for the highest ever. A La Niña over the Pacific cooled ocean waters for part of 2018, keeping temperatures a bit lower. So far, 2019 is on track to be the warmest year in recorded history.

Global sea temperatures also set a record level in 2018. And glaciers continued to melt at an alarming rate for the 30th consecutive year.

The State of the Climate report is yet another in a series of expert, science-based reports that continue to sound the alarm about the climate crisis. Climate change is affecting our weather, agricultural productivity, water supply, public health and national security. Unfortunately, the facts continue to be drowned out for many people by blogs, pundits, and posts on social media.
