Why This Matters: Some of the Earth’s major circulatory systems are being altered by climate change, and now we can prove it.
The changes to weather and to the distribution of species on land and in the ocean could be devastating.
For example, the ocean currents study suggests these shifts will squeeze commercially important fisheries, especially in the Pacific Ocean because they are trapped with no more “room” to migrate north, and will also make sea-level rise much worse.
And warmer weather may seem like a nice thing, but it also brings with it diseases such as mosquito-borne West Nile Virus, dengue, and Zika, as well as tick-borne Lyme disease and Ehrlichiosis.
As Inside Climate News explains, there are “[e]ight major wind-driven ocean currents, known as gyres, circulate around vast areas of the ocean” and “these rotating currents shape the weather and ocean ecosystems in coastal regions such as the Gulf Stream along the U.S. East Coast. It is hard to detect the movement of these gyres, but now with 40 years of satellite data, it is possible to see the changes. And the study’s lead author warns that there is no reason to believe that the changes will slow down or stop in the years ahead. “As long as the global temperature keeps increasing, this movement of the currents cannot really stop, because the climate is not in equilibrium with CO2 levels. In our lifetime, I don’t think it will stop,” the author said.
Warmer Weather May Explain Tennessee Tornado
Kansas, Oklahoma and the Texas panhandle used to be famous as tornado alley, but now those storms seem to have shifted east in what is now called “Dixie Alley” — the large number of tornadoes in the southeastern U.S. is associated with above-average tornado counts for the United States according to one NOAA research scientist. Just this year, In January, there was a rash of 90 tornadoes, 82 of which occurred over the two days of Jan. 10 and 11. According to NOAA, those tornadoes were the result of a strong, spring-like storm weather system that brought heavy rain, and also damaging winds to numerous states across the south and southeast, including Louisiana, Mississippi, Alabama, Georgia, Tennessee, and Kentucky. And the lastest tornado outbreak in Tennessee fits this pattern as well.
A new study shows that climate change in the 150 years since the industrial revolution has canceled out the prior 6500 years of cooling. The study, conducted by researchers at Northern Arizona University’s School of Earth and Sustainability (SES), examined a new compilation of paleoclimate data along with new statistical analyses and found that millennial-scale […]
There’s been ample research to show that the Arctic is warming much faster than any other region on the planet. However, there’s been little media focus on what’s happening on the opposite side of the planet, until now. A new study published in the journal Nature Climate Change on Monday has revealed that the South […]
