At face value, you might think that the article’s topic is climate change. The title of the article clues us in though as to the real topic: trust.

The issue that we have in our current polarized country is one of trust. The question that the article asks is, “Should You Trust …?” While this article specifically discusses trust in climate science, the approach it takes applies to any scientific conclusion.

Where it starts is where many people are at: They don’t trust climate science conclusions.

This is not an article about the latest climate science research. This is not telling people they need to believe in science. It doesn’t call people stupid. It’s also not a scientific paper seeking to expand the boundaries of what we currently know about the topic. It asks a question some people are having and then builds an argument for why they should trust the science.

The author, Justin Gillis, starts with a topic of current interest, the eclipse, to draw interest. We know the eclipse is going to happen because we can make accurate predictions about planets and moons using science.

The point that he establishes is the ability of science to make predictions.

While climate science is a complex system and orbital mechanics is relatively simple by comparison, the basic idea that science allows us to make predictions remains the same. We trust the science of complex systems all the time:

When you let doctors inject vaccines into your children, you are responding to a prediction — based on evidence, of course — about how their bodies will react. Yet the vaccines do pose some risks, and a small proportion of children suffer side effects.

Correct predictions of climate science

Gillis then lays out a number of historical predictions that climate science has made that have been correct.

1. Temperatures will rise in response to emissions of greenhouse gases

The first prediction dates back to 1897 by a Swede named Svante Arrhenius. This establishes that this science isn’t new. It’s been around for a long time. The average global temperature has risen by more than 1 degree Celsius since the late 1800s. This doesn’t sound like much but keep in mind this is for the entire planet.

2. The average rise in temperature

In 1967, Syokuro Manage and Richard T. Wetherald produced arguably the first climate model. Their model predicted:

A doubling of the CO2 content in the atmosphere has the effect of raising the temperature of the atmosphere (whose relative humidity is fixed) by about 2 °C

While temperatures have only risen by approximately 1 °C, CO2 levels have only increased by 50% over this time period.

Manabe himself later stated:

Models have been very effective in predicting climate change, but have not been as effective in predicting its impact on ecosystem[s] and human society. The distinction between the two has not been stated clearly. For this reason, major effort should be made to monitor globally not only climate change, but also its impact on ecosystem[s] through remote sensing from satellites as well as in-situ observation.

3. As the surface of the earth warmed, the temperature in the highest reaches of the atmosphere would cool

The scientific theory behind this looks like:

Stratospheric cooling is due to the destruction of ozone by human-emitted CFC gases. Ozone absorbs solar UV radiation, which heats the surrounding air in the stratosphere. Loss of ozone means that less UV light gets absorbed, resulting in cooling of the stratosphere. Cooling of the stratosphere results in the formation of more polar stratospheric clouds, which require very cold temperatures to form. The presence of these clouds allows even more ozone destruction to occur, since the reactions responsible for ozone destruction occur much faster in clouds than in dry air.

This has also been confirmed.

4. The Arctic will warm especially fast

The Arctic as a whole is warming twice as fast as the rest of the planet.

Water from the melting Outer Mullwitzkees glacier flows down a basin the glacier once covered on September 8, 2016 near Hinterbichl, Austria.

5. The oceans will rise

The rate of change we’re currently seeing is 3.4 mm/year. Since the late 1800s, it’s risen almost a foot.

6. We will see heavier rainstorms

In 1995, scientists predicted:

A warmer world is likely to experience an increase in the frequency of heavy precipitation events, associated with a more intense hydrological cycle and the increased water-holding capacity of a warmer atmosphere.

We don’t have to look far to see this. Hurricanes would still occur if the temperature hadn’t risen, but the power of them has increased as a warmer atmosphere holds more moisture.

Trucks make their way through flood waters on a main road leading to the Arkema Inc. chemical plant that was in crisis during the aftermath of Hurricane Harvey.

In the Midwest, I’ve witnessed this firsthand with our thunderstorms. The National Climate Assessment published in 2014 confirmed this reporting that “large increases in heavy precipitation have occurred in the Northeast, Midwest and Great Plains, where heavy downpours have frequently led to runoff that exceeded the capacity of storm drains and levees, and caused flooding events and accelerated erosion.”

7. Heat waves will increase

As the average temperature increases, climate science also predicted the increase of heat waves and droughts. These predictions have also played out.

Houseboats are moored on a shrinking arm of the Oroville Lake reservoir which is now at less than 25 percent capacity as a severe drought continues to affect California on May 24, 2015.

Coda

There’s not much more that can be added. I’m not a climate scientist, nor is the point of this to go through all of the climate science.

Nevertheless, this is a great way to help increase trust in climate change. Ask the question: Why should we trust climate science? Ask people why they trust other science, why they trust weather reports (even if with a grain of salt), why they trust medicines.

The fight we’re in with the public isn’t so much about science. It’s about overcoming the fear, uncertainty, and doubt from corporate special interests like the oil industry.
