Climate Change and it's impact

 
There are myriad species on this planet blue. Mother Nature continues to take care of them and give life to many species, who are living with the principles as set by nature, one species that all other species with dislike, is the human beings, Why, because of massive damages inflicted on Earth from killing animals to conquering their homes. We have been polluting the earth, and what is the result of increasing the greenhouse gases, increasing the carbon dioxide levels increase in the temperature, and, ultimately, bringing massive changes resulting in what is called as the climate change. The changes have intensified and have also worsened with the impact of the Industrial Revolution, taking the center stage. What are we discussing under this article, we will focus on the increase in the carbon dioxide concentration, where we will look at some of the key steps. And we will also look at the temperature changes, and what are the impacts of climate change. First up, let's look at changes concerning the carbon concentration of about 18,000, years ago, carbon dioxide was little under 200 parts per million, and Earth was much colder back then. About 11,500 years ago. It reached about 270 parts per million warmer conditions that were prevalent, leading to the emergence of agriculture. When you look at the statistics, you also figure out that in case there are any changes, there have been somewhat minimal changes when it comes to carbon dioxide 270 parts per million or 200 parts per million. The changes that we see are about 70 parts per million or in fact, it can be scaled up to about a hundred parts per million. This is for about millions of years. But now, after the Industrial Revolution, what we have is a drastic change concerning the carbon dioxide concentration, they remain steady at close to 280 parts per million up to 300 parts per million for close to 10,000 years. But now, what we see is drastic changes in carbon dioxide concentration. Let's look at the numbers in 1960 it was close to about, 310 parts per million. In the year 1985. It was about 350 parts per million and for the year 2020, what we have. It is going up to 410 parts per million and this drastic increase of the carbon dioxide in the atmosphere is due to the presence of industrial activities, burning off the coal-burning of fossil fuels and also because of expansion of the agriculture and deforestation and infliction of pain that human beings have caused to the Mother Earth does the levels of co2 in the atmosphere has reached about 410 parts per million for the year 2020. This was the last experience, millions of years ago. Now what we have to focus on is concerning the temperature for the year 1850s, there was a considerable increase in temperature, but this was not huge in number. Now when you look at, years, 1975, again, there has been an increase in temperature. But then, this has given an upward trend where the temperature differential concerning 1850 is comparatively more. And concerning the year 2015, what we have is one-degree centigrade, an increase in the global average temperature from the pre-industrial era. So this one-degree centigrade, increase from the pre-industrial level up until 2015, and many changes shortly. What it will have is an impact on the environment. The 2003 European heatwave killed about 70,000 people. This is the impact of increasing temperature, the Amazon Fire of 2019 is an impact of increasing temperature and the bushfires of Australia are the impact of the increase in temperature. One of the important statistics, given the climate impact lab of the University of Chicago, put out a warning for India. Last year, in the year 2019. It said that the average Summer temperature would increase by about four degrees centigrade for most of the states in India is the issue of increase in temperature ultimately so what is called climate change and several changes that it will be inflicting on the environment. When you look at the number of changes that it can impact. It includes the components of weather like rainfall humidity and wind speed. One of the important characteristics of climate change is what we today have, which is called global dimming. What is global dimming, let's try and understand global dimming is another issue because of climate change, what happens is we are burning the fossil fuels, there is increasing the activities of the human beings, there is a devastation that we have created to the forest areas, and ultimately what happened there is the increase of the carbon dioxide and the increase of the aerosols that are present in the atmosphere. As we increase the aerosols and carbon dioxide, it creates a layer of clouds in the atmosphere. This layer of cloud will prevent all the solar radiation to reach the earth. So the solar radiation that is reaching the earth will comparatively be reduced and, as a result of which the average temperature, reaching the surface of the Earth is comparatively lesser. So what is global dimming global warming is a scenario where there is the increase in the temperature, global dimming is a scenario where it does not let the shortwave radiation of the Sun enter the Earth's surface, and as a result, the temperature soon can also reduce as well. This is what is called as global dimming, there could be a reduction in the photosynthesis, why plants do require all the sunlight for the photosynthesis and, ultimately, this could also reduce the agricultural activities, and the productivity as well, climate change has also been inflicting massively on the health is well how does it impact the health, the air pollution can also bring bronchitis, lung cancer, and it can also bring heart attack, as well, how heart attack our skin is porous in nature. When you apply ointment it is sucked by the skin, and that is how it can relieve the pain in our muscles, but with the same air pollution is resting on our skin. This can enter the blood cycle, and as it enters the bloodstream. It can also enter the heart and, ultimately, it can result in a heart attack, as well. So the health impact, resulting in lung cancer and heart attacks, has also become prominent because of climate change. This can also be put into multiple other perspectives, like hurricanes heat waves, and droughts are also the impact of climate change, to prevent all these activities. What we require is a reduction in greenhouse gas reduction in the burning of fossil fuels reduction in deforestation and ultimately reduction in the economic activities, but all the countries that developed and the developing countries are reluctant to comply with these rules. Why, because they fail in case they have to go up the menace of greenhouse gases, they have to suspend the economic activity in case they suspend the economic activity. This will result in the unemployment crisis, and at the same time. It may also result in inequality in the society, but what they forget right now is that the wealthy nations are already spending about 500 billion each year, and the global community on a global average is spending about 2.5% of the global GDP, because of negative impact on the environment. If the same money can be used on a positive connotation, we would be able to reduce greenhouse gases is one such argument. Then in the year 2009, there was the United Nations Climate Conference, the richest nations, the developed nations, all came together. They also pledge and promised that they would be giving about a hundred billion dollars to the developing countries, this money could be used for mitigation of climate change variations. But in the year 2017 statistics also revealed that the money they gave was only amounting to 71 billion and this money was not used for climate adaptation, policies, but was only used for mitigation and some of the money was also given in the form of loans, as well, and not direct dispersal by these developed countries. All this means that funding for these developing countries has again failed to reduce the impact of greenhouse gases. That is where the COVID-19 comes as a blessing in disguise for the environment. The world might be suffering economically, it might be suffering on a health basis. But COVID-19 has been a disgrace for the environment. It has been able to save the climate, it has been able to reduce the emissions from fossil fuels, and all this myth that the earth is healing on its own. So what the author says is that COVID-19 has laid a foundation, the same foundation of reducing the greenhouse gases has to be used by the global community, the technologists, the economists, and social scientists must plan for a sustainable planet based on the principles of equity and climate change the global leaders will have to take up the responsibility have to change their mindset and act on the looming climate crisis so that we have the issue of climate change and greenhouse gases.

How lockdown having a disproportionate impact on women

A disaster or catastrophic ends to have a disproportionate impact on women. According to the writer, this is because of the traditional gender-based role of women in society. For example, during the 2004 Indian Ocean tsunami, it was observed that the disaster had a disproportionate impact on women, mainly because of their gender-defined roles. Since women are generally seen as the traditional caregiver in the family, they lacked the required life-saving skills, and as a result, a relatively higher number of deaths count was registered amongst women during the tsunami. Then after the disaster, women who were rendered homeless were accommodated in relief camps. And it was observed that at these relief camps, women had to face abuse and molestation, and they even had to face hygiene and sanitation issues at these relief camps. similar challenges have been faced by women in the United States as well, which is frequently hit by tornadoes. similar challenges were noted during the 2018 19 f…

Are humans responsible for the COVID-19 pandemic

Humans responsible for the pandemic According to the UNDP. The spread of a zoonotic disease such as COVID-19 can be directly attributed to the overexploitation of biodiversity and ecosystems by human beings. The UNDP has said that several zoonotic diseases have affected human beings because of increased contact of humans with animals. Especially wild animals. So these diseases with a jump from animals to human beings are referred to as zoonotic diseases or zoonosis. And it is a direct outcome of the overexploitation of biodiversity and ecosystems through human activities. The UNDP report even says that it is not just COVID-19 but even tuberculosis, rabies, malaria, toxoplasmosis h1 none SARS, burst, Ebola Zika, etc. They are all examples of zoonosis that have jumped from animals to human beings. And in each case, the source can be attributed to the destruction of the environment and biodiversity through human activities
It is found that the coronavirus outbreak certainly comes from t…

Researchers found new symptoms of COVID19

Many COVID-19 cases have emerged from Europe and the United States, where many patients have reported a complete inability to smell or even to taste. So, this has given rise to questions, whether the SARS coronavirus is affecting our neurons that are responsible for smell and taste, or is it affecting other cells, which are involved in this olfactory function. A recent study conducted in India has shown that it is not the neurons that are being affected by the virus, but instead, it is a set of cells present in the upper regions of our nasal cavity that are being affected by the double Coronavirus. These cells include the sub Technicolor cells and the horizontal basal cells. But importantly, these cells are not directly involved in helping us smell. It means that these cells are not directly involved in the olfactory function. But these cells help us nourish and support the other cells, which are actually involved in the olfactory function. So this means that the novel Coronavirus is…
