The differences between global warming and climate change

The terms of “global warming” and “climate change” are often used by exchange. In scientific literature, climate change and global warming are associated with incomparable ways, even if they are distinguished phenomena. The simplest explanation for this link is that global warming is the main cause of changes in our current climate.

Here, we define both of these two understandings, and half how they are measured and studied, and explain the relationship between them.

What is global warming?

The international governmental plate (IPCC) has determined the global warming as “an increase in surface and sea temperatures combined on average throughout the world over the course of 30 years.” For more than a century, research was conducted to measure and determine the exact causes of global warming.

Sensors throughout history

The average surface temperature of the Earth increased and decreased throughout the history of our planet. The most complete global temperature dates, as scientists have a high level of confidence, to 1880. Before 1880, notes come from farmers and scientists who recorded daily temperatures, early in the seventeenth century, daily temperatures, rainfall measurements, and the first and last frosts in their personal diaries. This data is often found to be accurate compared to automated data.

For long -term data, moon pathologists (scientists who study old climates) depend on historical differences in the population pills, the development and decline in ice rivers, ice cores, chemical welfare of rock rings, tree sites, coastal line changes, lake deposits, and other proximal data.

Scientists are constantly improving the accuracy of the recorded data, how to explain and design it. The temperature records vary depending on the region, height, tools, and other factors, but the closer we approach the present time, the more scientists are about the facts of global warming.

Natural events such as the effects of the asteroid and the main volcanic eruptions, for example, can have dramatic effects on global temperatures, which leads to the extinction of the mass. Periodic changes in the Earth’s position for the sun, called Milankovitch coursesIt can affect global temperatures and have long-term effects on the climate over thousands of years-although they do not represent the shortest changes that have witnessed over the past 150 years.

In fact, for the current era, a pattern of data is highlighted: the average Earth’s temperature has increased more quickly in the past fifty years compared to any event in the past.

Greenhouse

Starting in the mid -nineteenth century, scientists began to determine the changes in carbon dioxide concentrations as a major cause of global temperature changes. In 1856, the American physicist UNICEF Foot was the first to explain how carbon dioxide absorbed solar radiation. Its suggestion that “an atmosphere of this gas will give our land a high temperature” is now a common understanding among scientists about the causes of global warming, the phenomenon is now known as the effect of the greenhouse. In other words, levels of carbon dioxide and other greenhouse gases in the atmosphere lead to a warmer climate. Soon, Foot contributed three years later by the Irish physicist John Tindal, who is usually credited with describing the effect of the greenhouse.

By 1988, James Hansen, director of the Juddard Institute for NASA Space Studies, can witness a high degree of confidence “that there is a” relationship and the cause of influence “between the effect of the greenhouse and the observable warning. Hansen was talking about the last global warming, but the “high -confidence degree” applies to the moon’s diseases as well. Through their existence, since the appearance of life on Earth, carbon -based life has changed the levels of carbon dioxide in the atmosphere.

Causes of human beings

Humans have caused the most rapid and severe changes in global temperatures. Since James Hansen’s testimony of 1988, the level of confidence in the human causes (which a person causes) has grown to global warming to be functional unanimously within the scientific community.

These human causes are not new. Early in the year 1800, the natural world of Alexander von Humoult noted how forest removal sparked temperatures in the regional atmosphere. Just as forest fires today release tons of carbon dioxide in the atmosphere, the burns that are controlled were a source of carbon added for centuries.

However, these traditional practices decrease the number of greenhouse gases emitted since the beginning of the eighteenth century with the development of the coal -working steam. Coal burning expanded a hundred times in the nineteenth century, and grew by another 50 % by 1950, multiplied three times between 1950 and 2000, then doubled again between 2000 and 2015. Oil consumption followed a faster growth curve, expands between 300 times between 1880 and 1988, then grows 50 % to 2015.

Burning fossil fuels, from which greenhouse gases emitted primarily from carbon dioxide, methane and nitrous oxide, may be its peak in 2017, but still represents 82 % of the world’s initial energy use in 2021.

Parallel to fossil fuel consumption and high global surface temperatures are remarkable. He greenhouse gas emissions have increased to “unprecedented levels in the last 800,000 years” which is “which” which is “Most likely The dominant cause of the remarkable warning since the mid -twentieth century was, “according to IPCC.

There is a simple way to understand how fossil fuels contribute to the global warming phenomenon is to think about a blanket. The burning fossil fuel caught the ground in a blanket of pollution, which prohibits heat. The higher the number of fossil fuels we burn, the thickening of the blanket, the more heat can be surrounded.

What is climate change?

The climate is the weather for a long time. Changes in the climate resulting from the phenomenon of global warming caused by human being, and will continue to have long -term effects. These effects, which were once believed to start at one time in the near future, are increasingly visible today, with the most visible changes in weather patterns. But sebaceous changes in the entire ecosystems are also a very serious threat.

Hald weather

Make global warming from brutal weather and more stable, as natural disasters showed “huge increases in recent decades” in both intensity and hesitation. Natural disasters “once in the century” such as forest fires, deadly waves, droughts, floods, tropical storms, hurricanes, snow storms and ice collapses increased by 10 times since 1960.

According to the World Meteorological Organization, over the past fifty years, half of registered disasters and 74 % of relevant economic losses due to weather, climate and water risk such as floods.

The weather is attributed to climate change

It is often difficult to attribute any harsh weather event to global warming. Natural contrast in the climate is responsible for short -term changes, from one year to another in weather patterns, especially at the regional level. But the longest -term air events reveals a hand of climate change.

What can be attributed to global warming is a variable climate, as it increases warm oceans and warmer air from the possibility and severity of dehydration, heat waves, storms, hurricanes, and other harsh weather events. Attributing extremist events is a matter of more possibilities than certainty, given that the conditions that are often involved have no historical precedents.

But by comparing current extremist events with historical events with different intensity and different weather conditions, scientists can increase strict explanations in an increasingly strict role that global warming played in harsh bad weather.

While there is a dispute often within the scientific community about the level of influence on climate change in one extremist event, there is a strong agreement that the change of climate caused by man plays a pioneering role.

Threats to ecological systems

More deadly of natural disasters is the threat of climate change to the biological environment of the Earth, the ecosystems that support life. The types that try to adapt to the changing climate often fail.

Coral, for example, dies where the oceans absorb carbon dioxide in the atmosphere and are increasingly acidic. When the lands of peat and coastal wetlands dry due to high temperatures, dead plants are more quickly decomposing and warm gases, which contributes to a “consecutive effect” as one of the disaster contributes to the next stage. The climate -based “transformation points”, which are already underway, lead to great losses in biological diversity and undermining the entire ecosystems.

Climate change research still contains unknown and doubts. It is easier to understand the past than predicting the future of the planet’s physical and biological systems of the entire planet. However, the main uncertainty is less than the difficult sciences of climate change and more than the social sciences of how humans respond to it.
