Throughout the recent record-breaking and deadly heat wave that affected millions across Texas and other parts of the Southwest, major TV networks largely failed to report on the links between climate change and the extreme heat. Over a two-week period from June 15-29, an analysis by Media Matters found: Only 5% of the 310 segments and weathercasts about the heat wave across national TV news mentioned climate change. Major cable news networks – CNN, Fox News Channel, and MSNBC – aired 187 segments or weathercasts about the heat wave, but only 8 mentioned climate change. MSNBC mentioned the connection between the extreme heat and climate change 5 times and CNN mentioned it 3. Corporate broadcast networks – ABC, CBS, and NBC – aired a combined 123 segments or weathercasts that discussed the heat wave, but only 7 mentioned climate change. ABC led the way with 5 mentions, while CBS and NBC each mentioned the connection between extreme heat and climate change once.
The earth has gone through many warming/cooling changes throughout its history (we know this from examining core samples from polar ice and rocks from across the globe). We only have approximately 140 years of specific temperature data for a planet that is 4.5 billion years old. It’s premature to be Chicken Little yet.
It’s true that the Earth has gone through many warming/cooling cycles. We have more than 140 years of temperature data. Scientists are able to use samples from ice in polar regions to accurately trace temperature back more than 200,000 years. There are also geological and botanical signs that scientists are able to use to give approximate temperatures.
The difference between past cooling cycles and present-day isn’t that we are getting hot, it’s the rate in which we are doing so.
Even in the 140 year span that we’ve been using thermometers and able to record data purposefully, the past 30 years has rapidly increased. Historical records show that the temperature increase we’re experiencing is something that used to happen over multiple millennia, not within a century or two.
Are you aware how long it takes to go through those warming and cooling cycles though? Human activity is clearly the cause of this current warming.
Here’s a nice visual representation. Please don’t eat the crayons. https://xkcd.com/1732/
