Fact Check: "Global warming is real"

What We Know

The claim that "global warming is real" is supported by an overwhelming consensus among climate scientists. According to a study published in a peer-reviewed journal, approximately 97% of climate scientists agree that human-caused climate change is occurring (Orchinik et al., 2024). This consensus is based on extensive scientific evidence, including direct measurements of rising surface air temperatures and subsurface ocean temperatures, as well as observable phenomena such as increases in average global sea levels and retreating glaciers (NASA Science).

Furthermore, the Intergovernmental Panel on Climate Change (IPCC) has stated that since systematic scientific assessments began in the 1970s, the influence of human activity on climate warming has evolved from a theoretical concept to an established fact (NASA Science). This body of evidence is supported by numerous scientific organizations worldwide, which have issued public statements affirming the reality of anthropogenic climate change (NASA Science).

Analysis

The evidence supporting the reality of global warming is robust and comes from multiple credible sources. The study by Orchinik et al. highlights the effectiveness of consensus messaging in shaping public perceptions about climate change, indicating that when people are informed about the scientific consensus, their belief in human-caused climate change increases (Orchinik et al., 2024). This suggests that the scientific community's agreement on the issue plays a significant role in public understanding.

NASA's scientific consensus page further reinforces this by detailing the various lines of evidence that demonstrate human activities, specifically the burning of fossil fuels, as the primary driver of recent climate changes (NASA Science). The credibility of NASA as a source is high, given its status as a leading scientific organization with a long history of climate research.

While some segments of the population remain skeptical, studies show that a significant majority of Americans (approximately 74%) acknowledge that global warming is happening (Yale Climate Communication). This indicates a growing recognition of the issue, although there are still challenges in bridging the gap between scientific consensus and public belief.

Conclusion

The claim that "global warming is real" is True. The overwhelming scientific consensus, supported by extensive evidence and research, confirms that human activities are significantly contributing to climate change. The effectiveness of consensus messaging in shaping public perception further underscores the reality of this phenomenon.
