Levels of Ground-level Ozone Pollution Can Increase in Summer. As ground-level ozone requires the presence of sunlight to form, high heat and sunny weather can function to increase concentrations of this particular pollutant. Elevated ground-level ozone may also severely reduce crop yields during their primary growing season.

Over 156 million people in the US are exposed to unhealthy levels of air pollutants, according to the recently published 2025 State-of-the Air report from the American Lung Association (ALA). It presents air pollution data at the county-level for two pollutants, deadly fine particulate matter (PM 2.5 ) and ground-level ozone.

For more on other harmful aspects of Project 2025, see this blog. The Heritage Foundation’s blueprint—Project 2025—to dramatically alter the US Environmental Protection Agency should concern you. Project 2025 takes aim at all those protections. Project 2025 takes aim at grants, as well. It does me.

When fuels are burned to create energy in a process called combustion, black carbon along with carbon monoxide and other compounds are created because there is not enough oxygen in the atmosphere for the reaction to go to completion. Whenever there are combustion processes, of which there are many in our industrial society (e.g.,

The emissions make a significant contribution to climate change because methane is a highly potent greenhouse gas which, in the first 20 years after it is released, traps approximately 84 times more heat in the earth’s atmosphere than carbon dioxide (on a per ton basis).

BRUSSELS — The world can avoid the worst consequences of climate change, but emissions need to peak by 2025, the U.N.’s This latest report looks at mitigation — or what the world can do to stop pumping greenhouse gases into the atmosphere. Even 2 degrees becomes unlikely without a peak by 2025. We are at a crossroads.
