What is in this article?:
- Southeast climate not following global warming trend
- Southeast and Florida not much warmer
- IPCC report has weaknesses
- Intergovernment Panel on Climate Change says that man’s activities and greenhouse gases are at least half to blame for rising global temperatures.
- The Southeast, including northern and central Florida, is one region in the world that hasn’t experienced much warming due to greenhouse gases.
- In Florida, man has impacted temperatures, but mostly due to urban development where concrete and asphalt now absorb and hold more heat than the natural environment they replaced.
THE UNITED NATIONS sponsored Intergovernment Panel on Climate Change assessment says with higher certainty that man is to blame for global climate warming. But in the Southeast, that warming trend doesn't seem to be happening.
IPCC report has weaknesses
IPCC reports are the authoritative opinion on climate science, he says, but the report and the process used to develop the report has some weaknesses.
“First, it is a cumbersome process to compile the thousands of publications and experiments into a coherent document, and newer research and findings can be left out. In some ways, the report is outdated before it is published,” he says.
It seems, too, that over the last 15 years, global warming has stopped since a record warm year in 1998, which was caused by a strong El Niño. The IPCC says this is "due to natural variability, trends based on short records are very sensitive to the beginning and end dates and do not in general reflect long-term climate trends."
“This statement is true and most scientists believe that the recent slowdown in warming is just a temporary speed bump. However, the climate models used in the 2007 assessment all failed to predict this slowdown in warming. At best that means the models are failing to reproduce internal variability at important time scales, at worst that the models are not properly representing an important physical process,” Zierden says.
Florida experiences climate-related risks, like drought, extreme temperature, heavy rainfall and hurricanes. It has for centuries. It’s part of the Southeast climate. Even so, “Decision makers need the highest quality, accurate, and scientifically sound climate information to help prepare for and anticipate climate risks and opportunities to build a more climate resilient society,” he said.
