Global warming

What is climate change? Is it the same as global warming? What are its main causes and consequences? Is it a lie? Find everything about climate change bel ow! Climate change is the global phenomenon of climate transformation characterized by the changes in the usual climate of the planet regarding temperature, precipitation, and wind that are especially caused by human activities.

In fact, they say that global warming refers to the rise in global temperatures due mainly to the increasing concentrations of greenhouse gases in the atmosphere. On the other hand, climate change refers to the increasing changes in the measures of climate over a long period of time — including precipitation, temperature, and wind patterns. Following the same line of thought, according to Climate.

Ultimately, this means that global warming is one side of the much larger problem of human-caused climate change. Unfortunately, coronavirus is likely bad news for ecology in the long-term because it is tied to a dysfunctional economic system. We explain why, here. We will gradually add our new pieces that connect climate change and sustainability with the current coronavirus outbreak.

When we talk about climate change, we are often talking about the increase in temperatures linked to industrial activities and in particular the greenhouse effect. Ultimately, the causes of global warming at least at its current rate are not natural but driven by the human economy and industries. Many scientists are studying this phenomenon and trying to understand how activities of human societies are responsible for this heating. These scientists are grouped together in the IPCC International Group of Experts on Climate , and they regularly publish reports studying the evolution of climate change, such as the one published in late The first assumptions about the greenhouse effect were made by scientist Jacques Fourier in , whose work was followed by several scientists who tried to quantify this phenomenon, like Claude Pouillet, John Tyndall and Svante Arrhenius.

In fact, Arrhenius was the one who conducted the first experiment that accurately validated and quantified the greenhouse effect, at the end of the 19th century. For decades, these discoveries were not taken seriously in the scientific community. At that time, many experts believed that nature could self-regulate and that the impact of man was minimal.

Notably, many scientists thought the excess CO2 would be absorbed by the ocean anyway, which is true within specific CO2 limits. Nevertheless, the thesis that global warming was linked with the greenhouse gases including carbon dioxide was proven to be true and validated in the s by Gilbert Plass.

Nowadays, with modern technologies, there is solid evidence that the concentration of greenhouse gases in the atmosphere affects the ability of the air to retain infrared radiation and heat. In the 60s, several scientists showed the assumptions on the greenhouse effect were actually real. For what matters, Charles David Keeling proved, for instance, that the concentration of CO2 in the atmosphere was gradually increasing thanks to its measurements near Hawaii.

By its turn, Roger Revelle also proved that the carbon gases released by burning fossil fuels were not immediately absorbed by the ocean, as was previously thought. A decade later, in , during the first Earth Summit, the definition of global warming and its consequences were broadly discussed and a year later, in , John Sawyer published a scientific report highlighting even more clearly the links between global warming and the greenhouse effect.

This was the first time there was a real consideration and a true definition of climate change as a public problem by international institutions. The Intergovernmental Panel on Climate Change IPCC was created in with the purpose of studying the evolution of the phenomenon of climate change and its consequences. It brought and stills brings together hundreds of scientists, climatologists, geologists, oceanographers, and biologists, but also economists, sociologists, engineers and other specialists in various fields — with the goal of having a global vision of this phenomenon.

The IPCC is structured in three working groups:. These models and forecasts are then used by governments and businesses, helping them to put in place strategies to combat climate change or adapt to it.

Thanks to the work of the IPCC and other groups of scientists working on the definition of climate change, we now better understand the consequences of this phenomenon in our lives. In the minds of many, climate change is a relatively distant problem that simply implies that it will get hotter.

Nevertheless, the consequences are much deeper and should be taken more seriously. As we have been watching in many different countries, from the US California to India or South Africa, the weather is getting disruptive. At the same time, the regulating capacity of oceans is also being affected by an increase in temperatures.

If global temperatures increase dramatically, ocean levels will not only increase — they will also be facing the ecological challenges of oceanic acidification and deoxygenation.

At the same time, forest areas e. Amazon rainforest , fragile ecosystems e. Furthermore, climate change is already challenging and can further challenge our societies. With the increase in temperatures in some countries, especially in Equatorial regions, the flow of climate refugees is changing and increasing , putting pressure in other countries to host them, help them strive and overcome political barriers.

The reasons for this move have to do with natural resources, such as drinking water, that are getting more limited and many crops and livestock that are unlikely to survive affecting locals but also the global economy of the several industries that rely on raw materials in specific locations because of the temperature being too hot or too dry, too cold or too wet.

Finally, businesses are also likely to be affected by climate change. Indeed, in a context where the climate is changing, companies need to be aware of the risks that they may face and be prepared to deal with them by developing CSR strategies that evaluate the i mpacts they may suffer. Events such as damaged crops, the loss of infrastructures, unexpected changes in market stocks, investors that ask for sustainability reports and the growing expectations of society for business to be transparent are variables to keep an eye on.

To fight climate change, we must first reduce our greenhouse gases GHG emissions. To accomplish this, the first step is to embrace renewable energies that are naturally replenished on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat, and avoid creating energy by the burning of fossil fuels.

We need to adapt our lifestyles to overcome these growing challenges that climate change is bringing. Like many social and scientific problems, climate change has been controversial from the start. Some scientists and critics have questioned climate change.

They are called climate-skeptics. Several arguments are invoked, for example:. No evidence or explanation has been provided to support this argument. This argument is often put forward by climate-skeptical scientists to question the media attention that climate change enjoys.

Their idea is that climate change is a natural phenomenon, normal and cyclical, and there is no need to worry about it. Some scientists have also questioned the human origin of global warming, explaining that CO2 released into the atmosphere by human activities does not really affect the climate nor the ecosystems of Earth. They argue that these gases are either regulated by ecosystems, that they are not released in sufficient quantities to have an impact, or that other gases such as water vapor have a greater impact on ecosystems.

Although all these positions are partly true, they do not call into question the human origin of global warming. Thus, CO2 is well absorbed in part by the ocean and by plants, but not fast enough to be regulated due to the huge contribution of human activities.

Other climate-skeptics argue that because climatology the science that studies climate is very complex and has many factors to consider, it is difficult or impossible to predict the consequences of an event such as the increase of CO2 concentrations in the atmosphere. These critics question the reliability of the IPCC models up to some degree and therefore their predictions. In the end, the overwhelming majority of global scientists in all relevant fields agree on the causes of climate change and most of its consequences on ecosystems and society.

Scientifically speaking, there is no doubt about the existence of global warming and climate change.

Cause and effect of global warming essay

Throughout its long history, Earth has warmed and cooled time and again. Earth has experienced climate change in the past without help from humanity. But the current climatic warming is occurring much more rapidly than past warming events. These natural causes are still in play today, but their influence is too small or they occur too slowly to explain the rapid warming seen in recent decades. Some of this warming will occur even if future greenhouse gas emissions are reduced, because the Earth system has not yet fully adjusted to environmental changes we have already made.

Climate Change: Meaning, Definition, Causes, Examples And Consequences

The effects of climate change span the physical environment , ecosystems and human societies. It also includes the economic and social changes which stem from living in a warmer world. Human-caused climate change is one of the threats to sustainability. Many physical impacts of climate change are already visible, including extreme weather events, glacier retreat , [7] changes in the timing of seasonal events e.

Global warming , the phenomenon of increasing average air temperatures near the surface of Earth over the past one to two centuries. Increases in greenhouse gases —i. Continued global warming is expected to impact everything from energy use to water availability to crop productivity throughout the world. Poor countries and communities with limited abilities to adapt to these changes are expected to suffer disproportionately. Global warming is already being associated with increases in the incidence of severe and extreme weather, heavy flooding , and wildfires —phenomena that threaten homes, dams, transportation networks, and other facets of human infrastructure.

For argumentative essay sample cause of global warming has absolutely no matter what my perspective on global warming. Jun 23, then worry no scientifically valid mechanism for college students. One of deforestation adds more. See all global climate change. Sep 24, global climate change?

Human activity is the main cause of climate change. People burn fossil fuels and convert land from forests to agriculture. Since the beginning of the Industrial Revolution, people have burned more and more fossil fuels and changed vast areas of land from forests to farmland.
