President Donald Trump on Sunday sent out an irresponsible and flat-out wrong tweet that once again shows his total ignorance on the issue of climate change
In case you hadn’t heard, snow is falling out of the sky in the Midwest and Northeast U.S. and parts of Canada.
Trump, who has repeatedly cast doubt on the existence and effects of climate change, wasted no time in deliberately confusing Americans on the difference between climate and weather.
“Amy Klobuchar announced that she is running for President, talking proudly of fighting global warming while standing in a virtual blizzard of snow, ice and freezing temperatures,” Trump tweeted on Sunday afternoon, mocking Sen. Amy Klobuchar (D-Minn.) for launching her presidential campaign in wintry conditions in Minnesota. “Bad timing. By the end of her speech she looked like a Snowman(woman)!”
Trump has made light of cold weather multiple times in recent months, suggesting that winter weather in certain parts of the country somehow contradicts global warming.
Experts have repeatedly noted that President Trump continues to confuse the climate and weather.
As NASA so helpfully explained, weather is the way the atmosphere behaves in the short-term. Is it cold and raining outside your window? That’s the weather.
The difference between weather and climate is a measure of time. Weather is what conditions of the atmosphere are over a short period of time, and climate is how the atmosphere “behaves” over relatively long periods of time.
When we talk about climate change, we talk about changes in long-term averages of daily weather. Today, children always hear stories from their parents and grandparents about how snow was always piled up to their waists as they trudged off to school. Children today in most areas of the country haven’t experienced those kinds of dreadful snow-packed winters, except for the Northeastern U.S. in January 2005. The change in recent winter snows indicate that the climate has changed since their parents were young.
If summers seem hotter lately, then the recent climate may have changed. In various parts of the world, some people have even noticed that springtime comes earlier now than it did 30 years ago. An earlier springtime is indicative of a possible change in the climate.
January 2019 was Australia’s hottest-ever month on record going all the way back to 1910, according to the monthly climate review released by the Bureau of Meteorology (BOM). It followed the hottest December on record for Australia, reports ABC Australia.
And just last week, an independent analysis by NASA and the National Oceanic and Atmospheric Administration (NOAA) found that the Earth’s global surface temperatures in 2018 were the fourth warmest since 1880.
Global temperatures in 2018 were 1.5 degrees Fahrenheit (0.83 degrees Celsius) warmer than the 1951 to 1980 mean, according to scientists at NASA’s Goddard Institute for Space Studies, or GISS, in New York. Globally, 2018’s temperatures rank behind those of 2016, 2017 and 2015. The past five years are, collectively, the warmest years in the modern record.
The year 2018 “is yet again an extremely warm year on top of a long-term global warming trend,” said GISS Director Gavin Schmidt.
It’s official! According to @NASAGISS & @NOAA, Earth’s 2018 global surface temperatures were the fourth warmest since 1880, with warming trends strongest in the Arctic region 🌡️. Stay on top of the trends at: https://t.co/oyaJrze27T pic.twitter.com/fSkYmG720m
