Summary: Based on multiple lines of evidence and decades of weather watching, we are convinced that climate change is real, largely human-caused, and already affecting our region. Practical, concerted action can help manage its risks.
At Capital Weather, we have documented the weather and climate of the DC area and the Mid-Atlantic for over 20 years. Our team has analyzed data, tracked storms, and observed the region’s climate through every season. Over that time, one conclusion has become increasingly clear: the climate is changing.
The broad scientific consensus, reflected in decades of research and summarized in major scientific assessments, is that climate change is real and that human activities — primarily the release of greenhouse gases from burning fossil fuels — are the dominant cause of warming since the mid-20th century. We agree with that consensus.
The changes in DC’s climate are unmistakable.
Heat extremes have become more common. Winters have warmed sharply, with cold outbreaks less frequent and less severe than in past decades. Heavy rainstorms capable of producing flash flooding have grown more intense. Tidal flooding along the Potomac River and Chesapeake Bay occurs more often than it once did. And nature is shifting, from earlier cherry blossom bloom dates to longer growing seasons.

Weather will always vary from day to day and year to year. But over time, the trends have become unambiguous and evidence is mounting that climate change is affecting both day-to-day weather and extreme events. The changes we have documented are consistent with what scientists expect in a warming climate influenced by both rising greenhouse gases and the growth of urban areas.
Looking ahead, climate change is likely to pose a range of challenges for the DC region. Extreme heat will place greater stress on vulnerable populations and energy systems. Heavy downpours may increasingly overwhelm aging stormwater infrastructure. Rising sea levels will continue to increase the risk of tidal flooding in low-lying areas. Even the types of plants that thrive in the region will gradually change as the climate warms.
None of this means the future is predetermined or that the most severe outcomes are inevitable. The extent of future climate change will depend in large part on the choices societies make in the coming decades. Reducing greenhouse-gas emissions, improving resilience to extreme weather, and investing in adaptation will lower risks.
We encourage our readers to stay informed about climate change, to talk about it with their friends and families and elected officials, and to consider steps that can reduce their own carbon footprints. Individual actions alone will not solve the problem, but they can contribute to broader societal changes that help reduce emissions and build resilience.
At the same time, we believe discussions about climate change are most productive when they are grounded in respect and curiosity. Reasonable people may approach this issue from different perspectives or emphasize different solutions. We do not believe in name-calling or marginalizing those with whom we disagree. Constructive dialogue is far more likely to lead to progress.
We also believe that the way climate change is communicated matters. While the issue is serious and deserving of attention, we are cautious about language that frames it in overly apocalyptic terms. The Earth is not on the verge of becoming uninhabitable, and we do not believe that hyperbolic or doom-laden messaging is either accurate or effective. In many cases, such framing can discourage engagement or polarize discussion.
Our perspective is more practical and optimistic: the sooner meaningful action is taken, the more manageable the changes ahead will be. Climate change is not a ticking time bomb with a single deadline, but a long-term challenge whose risks grow the longer emissions remain high and adaptation efforts are delayed.
As meteorologists and climate communicators, our goal is to present the science clearly, track how the climate is evolving in our region, and provide context for what those changes may mean for the people who live here. We consider it a paramount journalistic responsibility.
