The beginning of 2025 has been marked by severe weather patterns linked to human-induced climate change, with 2024 reported as the hottest year on record. Advances in climate science have enabled scientists to connect extreme weather events to climate change, illustrating the significant impact of rising global temperatures on weather patterns. Distinguishing between climate and weather is key to understanding these effects, as the slow rise in temperatures leads to more frequent and severe weather anomalies.
The onset of 2025 has been marked by severe weather anomalies, including destructive wildfires in Southern California fueled by wind gusts reaching 100 mph and significant winter storms impacting parts of the Mid-Atlantic and Southern regions. Concurrently, climate scientists have reported that 2024 was identified as the hottest year on record, attributed to human-induced climate change. In recent years, advancements in climate science have enabled researchers to assess the influence of climate change on extreme weather events such as heat waves and hurricanes, marking a shift from prior assertions that individual weather occurrences could not be linked to climate change.
While not all weather variations can be directly linked to climate change, the overarching trend of increasing global temperatures is evident in numerous extreme weather events. According to Justin Mankin, a climate scientist at Dartmouth College, “The trends in climate are shaping new weather possibilities that were maybe unprecedented.” He elucidates that while individual weather events might fluctuate, the climate trend represents a broader, more consistent change aligned with shifting global conditions.
Differentiating between climate and weather is fundamental; climate represents the long-term average conditions, whereas weather pertains to short-term fluctuations. This difference is articulated by climate scientist Danielle Touma of the University of Texas, Austin: “The climate is basically the clothes you have in your closet,” indicative of long-term preparation, versus the daily selection dictated by immediate weather conditions.
As Earth’s average temperature has risen approximately 1.3 degrees Celsius since the mid-1800s, scientists note subtle yet pervasive impacts on daily weather patterns. Deepti Singh, a climate scientist at Washington State University, highlights that, “Everything we’re experiencing, it is occurring in a different environment.” The diminishing number of freezing days across several states and the significant increase in heat waves over the last several decades exemplify these effects.
Moreover, climate change alters complex interactions between atmospheric and oceanic patterns, resulting in unprecedented weather phenomena. For instance, the intense heat wave that struck the Pacific Northwest in 2021 was significantly exacerbated by climate change and was facilitated by unique atmospheric conditions that had never been recorded in that region before. As Alex Hall, a climate scientist at the University of California, Los Angeles, notes, “We’ve kind of put the climate on steroids.”
Recent advancements in climate science, specifically detection and attribution methods, allow researchers to model how the climate would behave in the absence of human-induced fossil fuel combustion. By comparing these scenarios, scientists can elucidate the extent to which climate change influences specific weather events. A notable example includes Hurricane Helene, whose rainfall intensity was increased by 10% due to human-caused climate change.
The phenomenon of climate change underscores a significant alteration in the Earth’s climate system caused predominantly by human activities, particularly through the combustion of fossil fuels which releases greenhouse gases into the atmosphere. The ongoing increase in global temperatures has been linked to a rise in extreme weather events, including heatwaves, hurricanes, and wildfires. The distinction between weather and climate is crucial, wherein climate signifies long-term atmospheric conditions while weather denotes short-term variations. Recent advancements in climate science facilitate a deeper understanding of these links, allowing for the attribution of human influence on particular weather events, thus enhancing public and scientific discourse about climate variability and its consequences.
In summary, the dramatic weather patterns observed at the beginning of 2025 highlight the profound influence of human-induced climate change on weather systems. These anomalies, characterized by record temperatures and destructive weather patterns, are a testament to the advancements in climate science, which now allow for a clearer attribution of these events to the ongoing climate crisis. Understanding the differences between climate and weather, alongside the demonstrable impacts of climate change, is essential for preparing for and mitigating future weather extremes.
