Unveiling Earth’s Climate Patterns: A Comprehensive Look at Monthly Climate Data (2018-2019)

Our planet’s climate is a wildly complex, ever-shifting beast, constantly shaping weather patterns everywhere. Getting a handle on these patterns? Absolutely vital if we want to predict what’s coming down the pike and soften the blow of climate change. The good news is, recent years have handed us a mountain of data, letting scientists dissect climate trends with laser-like precision. So, let’s dive into a comprehensive look at monthly climate data from 2018 to 2019, spotlighting the key takeaways and those “wow, did that really happen?” moments that defined our planet’s climate then.

Global Temperature Trends: Still Climbing, Folks

Remember those old cartoons where the thermometer would explode when it got too hot? Well, according to NASA and NOAA, 2018 was like that cartoon, clocking in as the fourth warmest year on record since 1880! On average, global temps were a solid 1.5 degrees Fahrenheit (0.83 degrees Celsius) warmer than the average from 1951 to 1980. And NOAA chimed in, saying 2018 was a whopping 1.42 degrees Fahrenheit (0.79 degrees Celsius) above the 20th-century average. Here’s the kicker: the last five years, including 2018, are the warmest we’ve ever seen in modern times. The big culprit? You guessed it: increased emissions of carbon dioxide and other greenhouse gases, mostly thanks to us humans.

And 2019? The World Meteorological Organization (WMO) said that from January to October, the global mean temperature was roughly 1.1 ± 0.1 °C above pre-industrial levels (1850-1900). It was pretty much a lock that 2019 would land as the second or third warmest year ever recorded. To put it bluntly, the five-year (2015-2019) and ten-year (2010-2019) averages are almost guaranteed to be the warmest five-year stretch and decade we’ve ever seen.

Key Climate Indicators: The Usual Suspects

Okay, let’s peek at the vital signs. Several key global climate indicators are flashing red, all pointing to a planet that’s definitely feeling the heat.

• Greenhouse Gas Concentrations: In 2018, global atmospheric concentrations of greenhouse gases hit record highs. Carbon dioxide (CO2) reached 407.8±0.1 parts per million, which is 147% of what it was before the Industrial Revolution. And get this, measurements kept climbing in 2019. Methane and nitrous oxide? They also hit record levels in 2018. Not good.
• Sea Level Rise: The Global Mean Sea Level (GMSL) in 2018 was about 3.7 millimeters higher than the year before – a new record. Since 1993, the average rise has been about 3.15 ± 0.3 mm per year, and it’s even speeding up by about 0.1 mm per year. The main reason? Ice sheets are melting faster.
• Ocean Heat Content: The oceans are soaking up a ton of heat, and 2019 saw the highest ocean heat content ever measured in the upper 700 meters. It was noticeably higher than in 2018. Remember, the ocean absorbs over 90% of the extra heat from global warming. It’s like the world’s biggest sponge, but it’s getting full.
• Sea Ice Extent: Both the Arctic and Antarctic saw record lows in sea ice in 2019, especially from April to August. Less ice means less reflection of sunlight, which means more warming. It’s a vicious cycle.

Extreme Weather Events and Regional Impacts: When Things Got Real

2018 and 2019 weren’t exactly a walk in the park. We saw a string of extreme weather events that hit hard around the world.

• Heatwaves: If you felt like you were melting in recent years, you weren’t alone. Studies show that many major heatwaves since 2015 were made much more likely because of climate change caused by humans. For instance, that brutal heatwave in Japan in July 2018? Scientists say it would have been impossible without our influence.
• Tropical Cyclones: The Northern Hemisphere saw more tropical cyclones than usual in 2018.
• Flooding and Drought: Floods impacted over 35 million people in 2018. Hurricanes Florence and Michael were just two of the fourteen “billion-dollar disasters” in the US that year. And down in Australia, record heat and dryness made a bad drought even worse, leading to those devastating wildfires.

Data Sources and Accessibility: Dig In!

Want to explore the data yourself? There’s a ton of it out there, thanks to places like:

• National Climatic Data Center (NCDC)
• National Geophysical Data Center (NGDC)
• National Oceanographic Data Center (NODC)
• National Snow and Ice Data Center (NSIDC)
• NASA Goddard Institute for Space Studies (GISS)
• NOAA Climate Data Online (CDO)
• Copernicus Climate Change Service (C3S)

These are your go-to spots for historical weather data, satellite images, and all sorts of climate datasets.

Conclusion: Time to Get Serious

The climate data from 2018 and 2019 isn’t just numbers on a page. It’s a wake-up call. Our planet is warming, sea levels are rising faster, greenhouse gases are piling up, and extreme weather is becoming the new normal. We need to get serious about tackling climate change and adapting to the changes already happening. By understanding these patterns and using the data at our fingertips, we – policymakers, scientists, and everyday folks – can team up to build a more sustainable future. The clock is ticking, let’s get to work.
