Colorado air quality regulators will move forward with a controversial, first-in-the-nation rule to curb greenhouse gas releases from oil and gas operators based on the intensity of emissions relative to their production.
Climate change has been a major environmental concern for decades, and international agreements have required countries, including Iran, to reduce greenhouse gas emissions and use fossil fuels. However, some experts believe that our country's actions in this area have been insufficient.

Amy Townsend-Small, an associate professor of environmental science at the University of Cincinnati, has been studying the second-most abundant greenhouse gas emitted through human activities for over a decade.
Global greenhouse gas emissions must peak in the next four years, coal and gas-fired power plants must close in the next decade and lifestyle and behavioural changes will be needed to avoid climate breakdown, according to the leaked draft of a report from the world's leading authority on climate science.
