Researchers from Southern Methodist University discovered the extraordinarily well-preserved fossil leaves from two sites in the Ethiopian Highlands. The fossils were approximately 22-26 million years old. The data collected from the samples indicate the presence of high CO2 levels, knowing that atmospheric CO2 affects the carbon fixation in leaves during photosynthesis. Pairing this information with previously studied ocean temperatures from the same time period confirms the three of greenhouse gasses and atmospheric global temperatures.
The scientific community has been looking for to confirm global warming due to high CO2 emissions. With information around the world from researchers on the effects of rising global temperatures, rising carbonic acid levels in the ocean, progressive bleaching of coral reefs, and extreme weather globally, human intervention is eminent. Raising awareness and proactive changes to decrease CO2 emissions must take place. https://www.sciencedaily.com/releases/2017/11/171114123256.htm

Researchers at the Arc Centre of Excellence for Coral Reefs Studies, have reproduced reef conditions in a laboratory setting. with growing levels of CO2 globally, dissolved CO2 in ocean water is causing OA. Published just last month, the article indicates optimism for the reef's ability to cycle overnight and recalibrate "natural daily changes in concentrations of dissolved CO2". Professor Philip Munday, the article senior author, indicated shallow water reefs are more susceptible to substantial fluctuations in water chemistry. The data from the study suggests that the daily fluctuations in the water's chemistry is enough for the small reef fish to recover, further reducing their sensitivity high CO2 levels.
Continued losses to thecae's costal reef systems could have tremendous impacts on fish nurseries and juvenile populations. Having such a large role in keeping the balance of predator and prey fish cycle in balance. The health of our reef and biological dwellers who make it in their home is extremely important. https://www.sciencedaily.com/ releases/2017/08/170831091420.htm This article presents facts and figures on a simulated climate control on possible category 5 hurricanes hitting Florida during the ice age between the Younger Dryas and Holocene era. The study conducted by the Geological Society of America, submitted on October 5, 2017, used core samples of ancient turbidite deposition in the southeast United States to assess possible anomalies: anomalies were found indicating quite a bit of hurricane activity. They then used computer models to assess ocean currents, temperatures, and weather. They discovered a slowdown of the currents in the Atlantic Meridional Overturning Circulation which then caused hurricane storms in cold water conditions.
Having credible information on ocean currents and the effects to weather could help scientists reach lawmakers and governing bodies all over the world to take note of climate change and implement changes. Knowing that hurricanes can form in cold water situations due to currents, may help then to better understand current conditions and weather predictions: especially after the 2017 Atlantic hurricane season. Furthermore, the action of the sampling may implore more research in near shore drilling for historical knowledge and use in predicting and comparing current. <www.sciencedaily.com/releases/2017/10/171005125028.htm> This article illustrates the importance of continued monitoring and further research into anthropogenic warming. Just last week Irina Marinov, a study author and assistant professor at the University of Pennsylvania’s Department of Earth and Environmental Science in the School of Arts & Sciences, released this article. Within it researchers have observed from past polynyas, the effect on warming sea and atmospheric temperatures. Over the past forty years the gaps have closed but just last year monitoring has uncovered another alarming polynya. These raised temperatures have caused increased precipitation in the lower latitudes, even affecting the Northern Hemisphere climate.
Rising temperatures could affect crop planting and harvesting schedules. Such changes will have adverse effects on the ability to plant cash crops due to saturated ground. Other potential hazards to the inhabitants is what is actually happening now in the Northern Hemisphere’s Atlantic hurricane season. Causing a larger number of hurricanes to develop, with increases in intensity. Further collateral damage from an increased intensity of storms would be property damage, human health concerns and loss of life. <www.sciencedaily.com/releases/2017/09/170911122659.htm>. |
