Since its initial introduction as a concept in the 1970s, scientists, political leaders, and activists have given various responses when asked to define global warming. The theory, which links rising global temperatures to such scenarios as greenhouse gas emissions, is frequently connected to the broader issue of climate change.
Inez Fung is a professor of atmospheric science at the University of California, Berkeley. She specializes in climate change and has worked with a team of peers in recent years to develop theories on global warming.

In early 2014,
Fung was part of a team of scientists in the United States and United Kingdom that studied issues surrounding global warming and related concepts. Their publication is titled Climate Change: Evidence and Causes.
Global warming is a concept Fung and her colleagues touched on in the report. “There will always be cold nights and cold days in these warming trends, but what we expect is that they will be rarer and rarer,” Fung said in defining global warming.
Immediately after the report was released, Fung also discussed what she believed to be misconceptions of global warming. She took aim at opponents who point to recent cooling trends, including anomalies through such patterns as the polar vortex that caused temperatures to plunge to record lows in portions of the U.S. in early 2014.
In the report, Fung and her academic colleagues stated global warming trends do not move in a linear, constant direction. Instead, she equated the momentum to a staircase that goes up and down but has a clear overall direction through a large span of time.

In 2009, Fung also led a research project that concluded global warming has caused for
shifts in seasonal weather patterns.
“We’re saying that, on top of the long-term trend of warmer summer and winter highs, peak warming is coming earlier within the year,” Fung said of the findings derived from a report from a team of scientists with UC, Berkeley and Harvard University.
In her attempt at defining global warming, Fung pointed to historic global surface temperature measurements that were taken between 1850 and 2007. While there were plenty of variables within the 157-year sample period, Fung said an analysis of the hottest day of the year in the Northern Hemisphere revealed a peak of 1.7 days earlier through the conclusion of the studied time period.
