The word "climate change" is a general one that can be used to describe both the causes and the results of changes to the Earth's climate on a local, regional, or global scale. In recent decades, the term "climate change" has primarily been used to refer to alterations in the Earth's climate that have been primarily caused by human activity since the pre-Industrial Period (around 1850 onward), particularly the burning of fossil fuels and the clearing of forests, which have led to a relatively quick rise in carbon dioxide concentration in the atmosphere. Given that it is one of the most significant indicators of global changes, the terms "global warming" and "climate change" are frequently used interchangeably. The term "global warming" refers to the increase in average global temperatures, which has a substantial effect on ecosystems, species, and people worldwide. The phrase "climate change" is used to refer to these extra effects because there are more variables and consequences than just an increase in surface temperatures. There is broad agreement among scientists—representing 97% of climate scientists who are actively publishing work, that human activity has been the main driver of observed warming trends since the 20th century. As of early 2020, the atmospheric carbon dioxide concentration has increased from a pre-industrial average of 280 parts per million (ppm) to 413 ppm. In recorded history, there has never been a concentration of carbon dioxide this high. According to scientists, in order to stop global warming from accelerating, we must reduce CO2 levels to a "safe" level of 350 ppm by the year 2100.
The increased severity, scope, and frequency of storms, droughts, wildfires, and extremely high temperatures are all significantly exacerbated by the heating and turbulence of the atmosphere caused by greenhouse gases, which also makes the weather and climate less predictable. "Climate change" refers to long-term modifications to temperature and weather patterns. Natural phenomena like variations in the solar cycle may be to blame for these modifications. However, human activity, notably the burning of fossil fuels like coal, oil and gas - have been a major contributor to climate change since the 1800s. The burning of fossil fuels sends greenhouse gases into the atmosphere, trapping heat from the sun and increasing temperatures. The heat-trapping greenhouse gases in our atmosphere's upper layers cause our atmosphere to "boil and churn," increasing its temperature, turbulence, and unpredictable nature. With each increase in atmospheric carbon, methane, or other greenhouse gas concentrations, our local weather and the planet's climate get more agitated, heated, and "cooked." Global warming is quantified by the increase in the planet's average temperature.
Climate change refers to a shift in a region's typical weather over an extended period of time, including changes in temperature and precipitation. For instance, the United States was largely covered by glaciers 20,000 years ago. There are fewer glaciers and a warmer temperature in the United States today.
Global climate change is the collective term for all the Earth's average long-term changes. Along with changing precipitation patterns and higher temperatures, these also include the consequences of global warming, such as:
- Increased sea levels.
- Mountain glaciers that are thinning.
- Greenland, Antarctica, and the Arctic's ice are melting at a quicker rate than typical.
- Shifts in the timing of plant and flower blossoming.
