Understanding Climate Change: Impact, Solutions, and What You Can Do Today

Should we still worry about climate change? It’s a question that has sparked many debates over the years. Going back to 2007, NPR hosted a discussion featuring six panelists divided into two groups: those claiming global warming isn’t a crisis and those arguing the opposite. Supporters of the “not a crisis” side, including a popular author, argued that climate change isn’t new, and that concerns were exaggerated. In contrast, the other side highlighted overwhelming scientific evidence linking CO2 emissions to serious consequences like rising sea levels and extreme weather.

Fast forward to 2010, nearly half of Americans believed that scientists disagreed on climate change. However, today the perspective has shifted. More people recognize that the scientific community largely agrees that climate change is real and caused by humans. Recent statistics show a growing recognition of climate-related disasters, such as severe floods and wildfires, which have made individuals more concerned about current events, not just the future.

Despite this evolution in public understanding, discussions around climate change have reverted to a debate format, often fueled by the government. A July 2025 report from the Department of Energy, titled “A Critical Review of Impacts of Greenhouse Gas Emissions on the U.S. Climate,” sparked controversy. Energy Secretary Chris Wright, appointed during the Trump administration, claimed climate change is serious but not catastrophic, suggesting that recent media coverage has distorted the science. He argued that CO2 actually benefits plants and questioned the severity of predictions made by climate models.

Critics quickly responded, pointing out issues in the report’s use of data. A fact-check by Carbon Brief found over 100 misleading claims in its 140 pages. Some experts, alarmed by the report’s conclusions, are organizing formal responses. Rachel Cleetus, a policy director at the Union of Concerned Scientists, expressed shock at the government’s denial of established climate science.

The report’s authors, some well-known for challenging mainstream views on climate, are seen as triggering a debate reminiscent of earlier years. They’ll encourage a “red team, blue team” approach, a method used in military strategy to stress-test ideas. While this method can help identify weaknesses, it can also mislead the public by creating a false sense of division where there is substantial agreement among scientists.

Matt Burgess, an environmental economist, argues that this revival of debate around climate science presents a missed opportunity. He believes discussions should focus on understanding the nuances and complexities of climate science rather than polarizing debates. For instance, while the majority of climate experts agree on human-caused climate change, questions still linger about specific impacts, like how it influences severe weather.

To effectively address climate challenges, experts urge collaboration between differing perspectives rather than relentless opposition. The University of Pennsylvania’s Adversarial Collaboration Project serves as an example, bringing together researchers with opposing views to solve scientific disagreements.

In concluding remarks, Burgess notes that the recent DOE report reflects deeper issues, such as declining trust in scientific authority. Travis Fisher, a director at the Cato Institute, cautions that using science solely to justify policies can breed skepticism. The consensus is clear: over 97% of climate scientists agree that human activities are driving climate change, but ongoing questions mean full closure on these discussions may not yet be attainable.

As we navigate the conversation around climate change, it’s crucial to focus on genuine dialogue and shared understanding. The urgency of acting against climate change cannot be ignored, as time is running out to mitigate potentially disastrous impacts.
