Tampa, Fla. (WFLA) – The annual report of the World Meteorological Organization (WMO) of the United Nations was released this week and the latest data shows no change in trend.
The climate is changing faster than at any time in modern history and shows no signs of abating.
United Nations Secretary-General Antonio Guterres has criticized what he calls a bleak light on humanity’s failures to tackle climate change. It’s true, the world has made very little progress in governing its dependence on fossil fuels and the consequent release of heat-trapping greenhouse gases.
The report updated the state of the climate change indicators for 2021 and outlined some of the more extreme weather events over the past year.
Since 1850, temperatures have increased by about 1.2 degrees Celsius, or 2 degrees Fahrenheit. This is the hottest earth in the last 125,000 years; since before the last ice age.
A 2 degree rise in temperature may not seem like much, but if your core temperature goes from 99 to 101 degrees, you’re definitely not going to feel all right.
However, warming is not likely to stop there. The Earth is likely to warm by at least 2 degrees Fahrenheit. This equates to a rise in your body temperature of 103 degrees.
While not a fatal blow, an increase in temperature will certainly damage your body’s connective functions, just as an equivalent increase in temperature on Earth would affect other bodily functions. its interoperability and the ecosystem services provided to humans.
90% of excess heat caused by humans is stored in the ocean. Thus, once again in 2021, the planet sets a record for the Heat Content of the ocean. Currently, the equivalent of four Hiroshima-class atomic bombs has the value of excess energy being stored in the oceans every second.
The oceans’ ability to store heat helps buffer the Earth’s air temperature, but returning hot temperatures haunt us by disrupting marine ecosystems, for example by smothering coral reefs. respiration and increased algal blooms.
Excess heat in the system is also accelerating the loss of glaciers globally. Since 1950, glaciers have lost the equivalent of about 100 feet of ice.
The melting of glaciers, combined with expansion due to warmer oceans, is driving sea levels higher. The rate almost doubles every decade. The current rate of sea level rise is 18 inches per century, but as the rate continues to increase, the actual increase by 2100 is at least another 2 feet, and possibly more.
In fact, a recent report by NASA and NOAA shows that the mid-way scenario (below) generates about 3.8 feet more sea level rise in the Tampa Bay Area by 2100.
Because there is a lot of uncertainty in forecasting iceberg instability, this number could change significantly by the end of the century.
Florida is on the verge of sea level rise due to climate change. Surrounded by water and close to sea level, the Tampa Bay Area is one of the most vulnerable areas to sea level rise. In fact, the NOAA report predicts another 2 feet of sea level rise in St Petersburg by early 2060.
