Fearful term for most of us when it comes to the future of our environment and its ill effects on our survival. Climate change is already being noticed and we are all increasingly contributing to the massive carbon dioxide content in our atmosphere.
Not sure if climate change is real? Here are some proofs
It is said that, in 1910 Glacier National Park was home to more an estimated 150 glaciers. As of June 2017 that number is 26 and shrinking. This national park is expected to eventually lose all its glaciers! (Source)
The atmospheric carbon dioxide concentration as of now is close 400 ppm and is escalating. This is higher than it has been in the last 800,000 years.
Most of the warming occurred in the past 35 years, with the five warmest years on record taking place since 2010. (NASA)

Who is contributing to the atmospheric CO2?
Human activities are undoubtedly the major cause with burning of fossil fuels being the major contributor to atmospheric CO2.
China is the largest contributor to atmospheric carbon dioxide (CO2) followed by the United states, India, Russia and Japan .
The amount of carbon dioxide emitted per capita in the United States is 16.5 metric tons that is almost 40 pounds per person !!
Carbon capture and storage be an effective solution?
Carbon dioxide (CO2) capture and storage (CCS) is a method which involves the separation of CO2 from industrial and energy-related sources, transport to a storage location and long-term isolation from the atmosphere. This approach of using CCS is increasingly being considered as an option in the process of mitigation actions for stabilization of atmospheric greenhouse gas concentrations.
The technology involves capturing CO2 produced by large industrial plants, compressing it for transportation and then injecting it deep into a rock formation at a carefully selected and safe site, where it is permanently stored. Maximum CO2 emissions come from the power sector. Other industries with major CO2 emissions include cement manufacturing, iron and steel production, chemical industries and vehicle emissions.
Several companies and universities are working towards CCS technologies.
Dimensional Energy is Cornell University Startup, licensed the technology to convert Carbon Dioxide to Methanol in 2018. Dimensional Energy has created an artificial photosynthesis process that converts waste carbon dioxide from power plant emissions into useful fuels and feedstocks of high values.
Another startup, Noble thermodynamics, uses its technology argon power cycle, close loop re-circulated cycle with monatomic gas as the working fluid which prevents the generation of harmful pollutants, permits the cost-effective separation of the resulting carbon dioxide (which can be used for industrial applications), and provides a quantum jump on the efficiency of the reciprocating engine, ultimately rendering a cleaner and more efficient system.
Carbon clean solutions is a UK based company uses the CDRMaxCO2 capture process which utilizes a proprietary solvent, process equipment and heat integrated process to provide energy efficient and economic CO2 recovery for industrial re – use.
Several researchers are working on this topic to create efficient CCS technologies as well
Few initiatives taken to reduce greenhouse gas emissions:
- The World Resources Institute (WRI) and the World Business Council for Sustainable Development (WBCSD) have partnered to develop The Greenhouse Gas Protocol.
- Global Mission 2020: To bring new urgency to the global climate conversation with a call to begin rapidly declining global greenhouse gas emissions by 2020.
- Countries pledged to make renewables of at least 30% of total global electricity generation in 2020, up from 23.7% in 2015.
- By 2030, Electric vehicles should make up at least 15% of new car sales globally, up from around 1% today.
- Japan has reduced carbon emission and pledged to reduce the carbon emission by 26% by 2030.
Carbon capture, storage and sequestration can be of major help for these initiatives.
We all hope that advanced technologies such as CCS come up to help us save our mother earth.
