Understanding Recent Climate Trends in the United States
Recent climate trends in the United States have been marked by significant developments, including the onset of a strong El Niño event, rising temperatures, and evolving public perceptions of climate change.
What is El Niño, and How Does It Affect the U.S.?
El Niño is a natural climate phenomenon characterized by the warming of sea surface temperatures in the central and eastern Pacific Ocean. The National Oceanic and Atmospheric Administration (NOAA) has officially confirmed the onset of El Niño, and it is expected to be among the strongest ever recorded, potentially surpassing the historic 2015–2016 and 1997–1998 events. Forecast models suggest a 63% chance that the event will reach very strong levels between November and January, with sea surface temperatures projected to rise as much as 7.2°F (4°C) above average in critical Pacific regions.

El Niño events influence global weather patterns, often leading to warmer temperatures and altered precipitation patterns in various regions, including the United States. The current event is expected to further raise global temperatures through 2027. (livescience.com)
How Are Temperatures Trending Across the U.S.?
In March 2026, the United States experienced unprecedented temperatures, with an average anomaly of 5.8°F across 192 cities. While the eastern U.S. experienced above-average temperatures, a record-shattering heat wave anchored over the West Coast drove the overall national trend. Eighty cities experienced one of their top five warmest March temperatures on record. (climatecentral.org)
Long-term April temperature trends have warmed since 1970 in nearly all major U.S. cities. A new analysis using the Climate Shift Index (CSI) shows that human-caused climate change is a key driver of these springtime warming trends in 98% of U.S. cities analyzed. Cities in the western U.S. experienced the most April days with temperatures at least twice as likely due to human-caused climate change (CSI 2), led by Colorado Springs, Colorado, and San Diego, California (14 days each).

What Are Public Perceptions of Climate Change?
A recent survey by the Pew Research Center indicates that about six-in-ten Americans believe that countries around the world, including the U.S., will not do enough to avoid the worst effects of climate change. This sentiment has increased among Democrats, rising from 51% in 2022 to 69% in 2026. (pewresearch.org)
The survey also highlights a growing pessimism about technological solutions to climate change. While about half of U.S. adults believe tech companies can do a lot to address climate change, few expect technology to actually solve problems caused by climate change in the future. Instead, many anticipate that major lifestyle changes will be needed to tackle these issues. (pewresearch.org)
How Is the U.S. Addressing Climate Change?
The federal government's role in addressing climate change has been a topic of debate. Majorities of Americans say the federal government is doing too little on certain aspects of environmental protection, such as preserving water and air quality and reducing the general effects of climate change. These shares are all modestly higher than they were during the previous administration, increasing 3 to 10 percentage points each. (pewresearch.org)
