The Earth's Core Activity

 

The Earth's core activity has gotten the attention of scientists. The core might have stopped spinning or is going in reverse. The Earth's core contains a liquid outer section and a solid part in the middle. The recent detection was done by analyzing seismic wave data. The data was collection from over the past 60 years. According to researchers at Peking University, the core could have stopped around 2009. Only now has it resumed its rotation, but in an opposite direction. The core tends to rotate counter-clock wise. There might be a pattern for which scientists do not know the reason for. Knowledge of the Earth's core is difficult to acquire. Getting equipment to the core for examination would require advanced engineering. The immense pressure would destroy any camera that could go there.  The outer core contains nickel and liquid iron. What core activity  demonstrates is more must be  discovered about Earth. Just below the surface is a unique environment. The change in core activity is nothing to cause alarm. There are no disturbances on the surface related to ecological systems. Rotation change according to the study occurred in the 1970s. Based on the models it is predicted another will happen in the 2040s. The information is of use to geology and geophysics. The Earth has certain movement cycles related to its core. The mystery is what is the purpose of changes in rotation. Seismologists are attempting to provide an answer. The technological limitations and gaps in knowledge remain obstacles.   

The Rise of Carbon Capture Plants

 

Carbon emissions have become a growing concern for safety of the environment. The exacerbation of the green house effect can cause an increase of the Earth's temperature. The challenge of climate change requires innovative solutions. What is developing is the rise of carbon capture plants. Iceland activated one of the world's biggest carbon capture plants on September 8,  2021. The Orca carbon capture plant takes CO2 and seals it underground. This becomes counted as a negative emission. The problem is that more of these plants would have to be constructed to make a significant change. Every nation  would need one to collectively bring down CO2 emissions. Only 15 direct air capture plants are in operation . The technology is new, so there needs to be more examination of its effectiveness. The Orca plant uses a combination of fans and filters to capture carbon dioxide. The CO2 is mixed with water. When pushed underground it will become rock.  A question does remain of the long term effects of this. Consultations with petrologists and geologists should be done before embarking on larger projects. From a perspective of ecology, carbon capture plants could be beneficial. A combination of planting more trees, investment in renewable energy, and creation of new technology can reduce extreme climate change. Carbon capture plants will become a priority in the coming decades.
