All About Extreme Temperatures: Causes, Consequences, and Solutions

The past ten years—frankly, the last five years alone—have shown a dramatic increase in extreme temperatures and precipitation leading to everything from extended droughts (which, themselves, lead to wildfires) to massive ice storms to mudslides to multiple Category 4 and 5 hurricanes. As our climate warms, temperatures and storm systems are altered; in some cases, significantly. And this has and will continue to lead to more and more severe outcomes.

But why is this happening? And is there anything that can be done to stop it?

The short answer: climate change, duh. And yes!

The long answer…well…let’s just get into it.

Weather vs. Climate

Square one: defining the difference between weather and climate. It might seem mundane or even a bit arduous, but the truth is, most people struggle to know the difference between the two terms. Luckily, we came prepared!

  • Weather: short-term changes in the atmosphere (e.g., a storm)
  • Climate: long-term changes in weather patterns, typically in a specific area

So, when scientists use the phrase “climate change,” it’s referring to the changes in weather patterns, temperatures, and levels of precipitation over years, and how these patterns compare to those in the decades—even centuries—that came before. These previous decades are referred to as “climate normals.” Scientists are then able to observe shifts in these patterns.

In the case of climate change, the increased release of greenhouse gases since the turn of the 20th century (in large part due to the advancement of industry and technology) has triggered significant changes in overall weather patterns around the world.

What's Causing Extreme Temperatures?

Greenhouse gases trapped in the earth’s atmosphere trap heat which, in turn, increases the surface temperature on earth. So far, Earth’s surface temperature has increased by approximately 1.2°C (or roughly 2.2°F). This trapped heat causes sporadic heating events, creating heat waves that are consistently hotter and last longer than those we’ve seen before. In fact, experiencing extreme heat and heatwaves is estimated to be ten times more likely now than it was pre-Industrial Era as a direct result of the increased greenhouse gas emissions.

According to the IPCC, “A heatwave that occurred once per decade in the pre-industrial era would happen 4.1 times a decade at 1.5°C of warming, and 5.6 times at 2°C.” Climate scientist Sonia Seneviratne suggests that an increase in temperatures higher than 2°C, “means that most years will be affected by hot extremes.”

Changes in the jet stream can also create “heat domes,” where the weather becomes stagnant—stuck in place—and instances of extreme heat sit over a region without moving for days or even weeks at a time.

The Problem with Increased Precipitation

A secondary side effect of the global temperature increase is precipitation. And lots of it. As temperatures increase, more surface water evaporates, collecting in the atmosphere and forming rainclouds. The more water vapor that exists in the atmosphere, the heavier the rainfall. As a result: Warmer Temperatures = Increased Precipitation = Increased Rainfall.

The Center for Climate and Energy Solutions estimates that for every degree of warming, water vapor in the air increases by 7%.

But it’s important to note that just because the water in one region vaporizes and forms rain clouds, it doesn’t mean that these clouds will precipitate in that same region. Clouds travel by way of jet stream and can be pushed to new locations before raining or snowing. Depending on the original climate of the region, this can lead to flooding, mudslides, sinkholes (due to shifting sediment), and more. Some climates get unusually dryer, falling into drought, while others become wetter—sometimes more so than the existing environment can withstand, which can lead to the previously mentioned issues.

Increased water vapor also leads to an increase in tropical storms and more dangerous weather systems (you can check out our article on hurricanes to learn how those are created). As the world gets hotter, the severity of these types of storms will continue to increase.

Can Extreme Heat Lead to Extreme Cold?

The short answer? Yes. Yes, it can.

Introducing the polar vortex. We won’t take a massive deep dive into the science behind it all (besides, the NOAA has done a way better job than we ever could—and with pictures!) but the short-and-sweet of it is this: both the North and South Poles are covered by something called a “polar vortex” in the atmosphere. This vortex, when stable, is made up of tightly circulating cold air that stays above a specific area, thus maintaining a consistently cold temperature.

However, scientists have discovered that as the earth and Arctic Sea waters begin to warm, the stability of these polar vortexes begins to reduce. As this happens, the polar vortex expands and starts sending frigid air southward. This can lead to extreme cold fronts and more and more severe winter storms.
