Teflon
History Teflon was an accidental creation in 1983, by a former resident of New Carlisle, a young boy name Roy J. Plunkett, who took a new job in DuPont. He had done PhD from Ohio State University in 1936. In DuPont Company Plunkett area was refrigerants. In 1930s most of the chemicals that are used for refrigerants are hazardously explosives. They use chemicals like ammonia and oxides of sulfur as refrigerants. These are pretty toxic compounds and been leaking out of the refrigerants and cause harm to the nearby environment. So, the Company DuPont and General Motors comes up with an idea to produce non-flammable refrigerants, a kind of Freons named as Refrigerants 114. He was given a task detect non-toxic and non-combustible coolants, that can easily be used in refrigerants. One day he opened the fresh tank of containing TFE gas which he wants to deliver for experimentation. When he weighed out these tanks he found some material of white powder appearance. After a large number of attempts, he found a slippery powder, today it is known as Teflon. This is a fun kind of accidental experiment for scientist, which keeps scientist to work for long hours for further experiments to find out the compound structure and its properties.

Glycemic load
The amount by which a food raises blood sugar levels after consumption is measured by its glycemic load. Compared to the glycemic index (GI), which only measures the speed at which a food's carbohydrates break down into glucose and enter the bloodstream, it is a more reliable indicator of how a food will affect blood sugar levels.

Should we try to cool the planet by reflecting sunlight?
The Philippines' Mount Pinatubo erupted in 1991, making it the second-largest volcanic eruption of the 20th century. A layer of aerosol particles was dispersed across the entire globe as its ash plume shot up past the atmosphere and into the stratosphere. Those particles formed a solar umbrella that reflected sunlight away from Earth, resulting in a half-degree Celsius decrease in global temperatures for nearly two years. It is not the first time that a huge eruption of a volcano has lowered global temperatures. El Chichón well of lava brought down temperatures by a comparable sum in 1982 as did other significant emissions throughout the last 100 years. Scientists are looking into whether we could use this phenomenon to combat global warming right now. Utilizing an innovation called sun based geoengineering. Allies say it's an instrument we want to truly investigate as environmental change deteriorates. gaining a deeper understanding of these issues, which has the potential to lessen suffering. That is worth very much. However, critics argue that the technology shouldn't be used to combat global warming because of the technology's risks. More technology isn't always better every time. Some innovations have been made that a lot of people wish had never been made. So which one is it? To comprehend the advantages and dangers of sun based geoengineering, I addressed a few researchers, legal counselors, native pioneers, areas of strength for both sides. Should we investigate solar geoengineering when the survival of the human race on Earth is at stake? All scientists agree on one thing: The planet could cool down through solar geoengineering. Reflecting daylight away from the earth prevents heat from getting caught in our climate. By injecting aerosols into the stratosphere like volcanoes do, we could accomplish that. That strategy has received the most research. Additionally, marine clouds' ability to better reflect the sun are the subject of research by some scientists. Space-based reflective shields are another possible approach. These initiatives are still in various stages of research, but in order to implement these technologies and achieve widespread cooling effects, we would need to massively alter our complex climate. The fact that we are currently on a pretty dire path is one of the main reasons that some scientists support solar geoengineering. Our emissions, primarily carbon dioxide, continue to increase. There's actually no inquiry we should cut emanations over the long haul. However, even if emissions are reduced to zero by tomorrow, climate risk remains. Simply put, it means that you stop the climate risk from getting worse because emissions accumulate. David Keith, a professor at the University of Chicago, is that. He clarified for me that except if we think past discharge decrease, the environmental change influences we're now encountering will keep on declining. According to a recent study, heat-related deaths are on the rise and account for nearly 10% of all global deaths. Supporters say that we need to use computer modeling to look into climate processes and develop technology to see if and maybe how this technology could be safely used worldwide with other solutions to reduce those effects. The thing is, meddling with our worldwide environment is exceptionally convoluted. The entire climate system is interconnected. The climate system's response could be significantly altered, unpredictably, by humans using technology. One of the major concerns regarding solar geoengineering is made reference to by Oxford Professor Raymond Pierre Humbert. Precipitation patterns around the world will change as a result of the addition of new elements to our atmosphere or stratosphere, potentially intensifying the extreme weather we are already experiencing. Almost everybody settles on these dangers. Additionally, you are unable to answer the most significant inquiries regarding the response of the climate system. Shy of a full scale sending. In terms of time and scale, a full-scale deployment would necessitate unprecedented global cooperation. However, the carbon dioxide we have transmitted since the modern insurgency and we emanate today will keep on warmingly affecting the environment for millennia from now regardless of whether we quit discharging. In any case, conversely, the sun oriented geoengineering procedures proposed have an exceptionally short lifetime in the environment. To make a kept cooling impact we would have to send them continually for quite a long time. This indicates that you are committed to establishing institutions and treaties that can be complied with for tens of thousands of years. And to impose that kind of burden on humanity in the future is truly unprecedented. On the off chance that there is a global conflict, war, worldwide despondency, or something that powers an unexpected end of sunlight based geoengineering, then, at that point, the world gets hit with this fast warming. Termination shock is the rapid warming. And one of the main reasons critics believe Solar geoengineering is ungovernable and unsustainable is the risk of it happening. In addition, our track record for figuring out how to move things along so far is pretty poor. In 2021, Sweden dismissed a spearheading undertaking to test sunlight based geoengineering innovation. Ecological and native gatherings gave a letter featuring "the potential for making definitely lopsided, capricious changes on environment, climate and biodiversity." furthermore "international strains it could stir". It would have a significant impact on our environment, ecosystem, and the precious ecosystems we are fighting for. To secure and protect and get and reinforce. Resistance like this is one explanation that most sun powered geoengineering research is occurring in labs with models and recreations. transforming the discussion about solar geoengineering into one about how far our research should go. 400 scientists wrote a letter in January 2022 calling for a non-use agreement on solar geoengineering.

Kyoto Protocol: Success or Failure?
INTRODUCTION Kyoto Protocol was adopted by UNFCCC and signed in Kyoto, Japan on 11 December 1997. It is a legal binding target for developed countries to reduce Greenhouse Gases emission. After a long delay, it finally comes under force in 2005, following Russia’s ratification s[6]. Presently 192 countries work under this treaty. United State America is the only country which never ratifies this treaty. In 2012, an amendment occurred in Doha called the “Doha Amendment”. During this amendment, Canada withdraws itself from this legally binding treaty. It is the only global treaty with binding measures to control Greenhouse gases .
