Climate change is real

Humans throughout the world are feeling the effects of climate change. Changing temperatures and precipitation patterns are the primary causes. All continents and ocean regions are feeling the results, with the most vulnerable locations being those at lower latitudes and with less infrastructure.

Is global warming a proven fact?

There is an almost unanimous scientific agreement that climate change occurs primarily due to human activities. The leading cause of climate change is pollution made by humans, and if we do nothing, it will grow considerably more dangerous in the future.

The term “climate change” refers to the cyclical shifts in weather patterns that occur on Earth due to variations in the Earth’s atmosphere and the feedback loops between the atmosphere and other geological, chemical, biological, and geographical components of the planet. Climate and climatic change affect all life forms, even if the shifts are slight and fleeting. Flowering plants lose their leaves due to a lack of water, while animals seek refuge and go into hibernation when the weather gets colder or drier. Life on Earth has evolved to tolerate climate change to some extent, which proves that climate change occurs; nevertheless, our own experience of climate change during our lifetimes, together with scientific data, also demonstrates that climate change occurs.

One way of looking at the weather we experience daily is as a form of climate change. Changes in temperature, wind speed and direction, and the distribution of precipitation (rain or snow) occur throughout a single day. All of these things are perceptible, yet they are rarely brought up in discussions on climate. Simply put, the weather is the current state of the atmosphere at a specific area and time. However, environment refers to the long-term (decades-long or more) average atmosphere condition at a particular location.

The amount of sunlight (solar radiation) reaching Earth’s atmosphere and the surface varies throughout the year, resulting in seasonal climate changes (though the shift can be modest in some tropical places). Droughts, floods, and other climatic extremes occur on an annual basis due to a variety of factors and interactions between Earth’s systems, such as variations in atmospheric and oceanic circulation patterns (such as El Nio, La Nia, the North Atlantic Oscillation, etc.) that alter the paths of storm tracks and the movements of air masses. Wet, dry, cool, or warm temperatures tend to cluster for multiple years in a row for specific regions, and these kinds of climatic shifts occur on durations that span decades. Earth’s axis processes (slowly rotates or “wobbles”), the planet tilts (obliquity), and Earth’s orbit elliptically shapes (eccentricity), all of which have feedback effects on climate for periods thousands of years beyond human lifetimes. Various sections of Earth’s surface receive different amounts of sunshine (and, by extension, solar heating) at other times of the year due to the interplay of these events. As time goes on, the quantity of energy in the mix will increase due to the gradual rise in the solar radiation that the Earth receives.

Is global warming a hoax? The aforementioned natural events prove this to be the case, yet this is by no means all there is to the narrative. Human activities also affect the climate, and experts agree that these activities are becoming an increasingly important factor in determining the atmosphere of Earth.

There is near unanimous agreement among climate experts that human activities are a significant contributor to the warming observed since the early 1900s. There are several pieces of evidence that point in this direction. Radiative forcing, or the heating impact produced by various influencing elements, is one of the primary threads (such as the albedo, or reflectivity, of the land and water and the concentrations of certain gases and particulates in the atmosphere). Radiative forcing has warming and cooling effects, and individual components can be either positive or negative. When looking at warming from an energy perspective, we find that around 342 watts of solar radiation reach each square meter of Earth’s surface annually. This amount can be attributed to an increase or fall in Earth’s surface temperature. Since the middle of the Industrial Revolution, the warming influence of positive forcing (dominated by increasing concentrations of greenhouse gases [carbon dioxide, methane, nitrous oxide, and other gases that absorb infrared energy released from Earth’s surface after sunset each day]) has outpaced the cooling influence of aerosols [such as Sulphur dioxide from volcanic eruptions and industry] and another negative forcing. Supporting the claim that Earth’s global and regional climates are changing rapidly, very likely much faster than they would if natural forces solely drove Earth’s climate changes, are decreasing Arctic sea ice coverage and rising global temperature averages (showing that many of the warmest years have occurred since 1980). Therefore, many researchers are beginning to question whether the rate of climate change on a global and regional scale is sufficient for many species to adapt and survive.

Will climate change be stopped?

Yes. Reduced human emissions of heat-trapping gases and soot (“black carbon”) can reduce the rate and restrict the amount of global warming.
