Those protests, being held Sept. 20 and Sept. 27, seek to raise awareness about climate change and advocate for aggressive environmental policy actions such as the Green New Deal, an outline for environmental action proposed by some Democrats in Congress. The first strike comes just before a United Nations climate summit.
Many scientists say the coming decade will be crucial to addressing climate change around the globe, and that countries must drastically curtail their carbon emissions produced by fossil fuels to avoid global temperatures rising. Research suggests that global average temperatures rising by 3.6 degrees Fahrenheit above pre-industrial levels would cause massive flooding in some areas, unprecedented droughts in others and generally irreversible damage to the world's climate and ecology.
According to the National Aeronautics and Space Administration, the earth's average temperature has already increased by 1.4 degrees since 1880, with much of that increase coming since 1975.
"The world is getting warmer," NASA's Earth Observatory website says. "Whether the cause is human activity or natural variability — and the preponderance of evidence says it’s humans — thermometer readings all around the world have risen steadily since the beginning of the Industrial Revolution."
Many scientists believe that warming is accelerating rapidly, that climate change is already affecting millions via droughts, extreme weather and flooding and that, without big changes, the globe could reach the point of no return in the coming decades.
That, climate activists say, means big political steps need to be taken now, and groups across the globe have organized climate strikes in other cities.
The local climate strike event is being organized by Cincinnati-based Young Activists Coalition and a statewide group called Ohio Climate Strike. Attendees are asked to make and bring signs calling for action on climate change. A number of speakers will address the crowd.
"Show support as we collectively signal that the status quo is insufficient in dealing with the crisis at hand, and that radical legislative and popular action needs to be taken to reverse course," those groups write on social media posts about the rally. "This isn’t just one climate strike, it’s a continuation of a movement that has begun to gain leverage as concepts like the Green New Deal and divestment become mainstream."
