What Is One Effect Of Climate Change – Life on Earth depends on energy coming from the Sun. About half of the light energy that reaches the Earth’s atmosphere passes through the air and clouds to the surface, where it is absorbed and radiated as infrared heat. About 90% of this heat is then absorbed by greenhouse gases and re-radiated, slowing heat loss to space.

Over the past century, the burning of fossil fuels such as coal and oil has increased the concentration of atmospheric carbon dioxide (CO

). This increase occurs because the process of burning coal or oil combines carbon with oxygen in the air to create CO

. To a lesser extent, land clearing for agriculture, industry, and other human activities has increased greenhouse gas concentrations.

Ice cores are scientists’ best source of historical data. Other tools for learning about Earth’s ancient atmosphere include growth rings in trees, which keep a rough record of temperature, moisture and cloud cover in each growing season for about 2,000 years. Corals also form growth rings that provide information about temperature and nutrients in the tropical ocean.

The industrial activities on which our modern civilization depends have increased carbon dioxide levels in the atmosphere by almost 50% since 1750

. This increase is due to human activities, as scientists can see a distinctive isotopic fingerprint in the atmosphere.

Data Driven Predictions Of The Time Remaining Until Critical Global Warming Thresholds Are Reached

In its sixth assessment report, the Intergovernmental Panel on Climate Change, made up of scientific experts from countries around the world, concluded that it is unequivocal that increasing CO

, methane and nitrous oxide in the atmosphere during the industrial era are the result of human activities and that human influence is the main driver of many changes observed throughout the atmosphere, ocean, cryosphere and biosphere.

“Since systematic scientific assessments began in the 1970s, the impact of human activity on system warming has evolved from theory to established fact.” – Intergovernmental Panel on Change

Scientists use a metric called Total Solar Irradiance (TSI) to measure changes in the energy the Earth receives from the Sun. The TSI includes the 11-year solar cycle and solar flares/storms from the Sun’s surface.

Climate Change And Its Effects!

Research shows that solar variability has played a role in past changes. For example, a decrease in solar activity along with increased volcanic activity helped trigger the Little Ice Age.

The graph above compares global changes in surface temperature (red line) and the Sun’s energy received by Earth (yellow line) in watts (units of energy) per square meter since 1880. Lighter/thinner lines show annual levels while heavier/thicker lines show 11-year average trends. Eleven-year averages are used to reduce natural year-to-year noise in the data, making underlying trends more apparent.

The amount of solar energy the Earth receives follows the Sun’s natural 11-year cycle of small ups and downs with no net increase since 1880. During the same period, the global temperature increased significantly. It is therefore highly improbable that the Sun has caused the observed global warming trend over the past half century.

But several lines of evidence show that current global warming cannot be explained by changes in energy from the Sun:

Such flooding that inundates roads and buildings along America’s West Coast is unusual outside of El Niño years, but that could change by the 2030s.

Data from NASA and other institutions show that the global decline of coral reefs is largely driven by change and other human actions, including pollution. While some corals survive even under harsh conditions, scientists stress the importance of taking action to better protect and manage reefs.

Methane “hot spots” in the Yukon-Kuskokwim Delta are more likely to be found where recent wildfires have burned through the tundra, altering carbon emissions from the ground.

The annual minimum (lowest) annual Arctic sea ice extent was the sixth lowest on record this year, while Antarctic sea ice reached its lowest ever maximum. Both continue a long-term downward trend due to human-caused global warming.

The International Surface Water and Ocean Topography Mission can measure ocean features, such as El Niño, closer to the coast than previous space-based missions.

The instrument will allow the non-profit organization Carbon Mapper to accurately locate and measure the sources of methane and carbon dioxide from space.

According to scientists at NASA’s Goddard Institute for Space Studies (GISS) in New York, the summer of 2023 was the hottest on Earth since global records began in 1880. Climate change is real, and the evidence is all around us. Although changes in Earth’s climate are nothing new, it is clear that the recent effects are having a devastating impact on countless people, places and wildlife.

You’ve probably heard the terms climate change and global warming used interchangeably. That’s because both describe changes in Earth’s climate. While global warming focuses on the rising average temperature of the planet, climate change usually refers to changes in things like precipitation, wind patterns, and temperatures over a period of time. Measured changes in climate can take years, decades, or even millions of years.

Climate change has been happening for as long as the Earth has existed. It happens every time Earth’s climate patterns change and stay in place for a measurable amount of time. This is especially evident in the natural cycles of cooling and warming. Before human causes began to change the global climate, five main factors interacted with each other as climate change occurred. These five factors include: [1]

The American Association for the Advancement of Science stated: “The scientific evidence is clear: global climate change caused by human activities is happening now, and it is a growing threat to society.” [2]

Greenhouse gases play a vital role in Earth’s climate cycles. As the planet is hit by the sun’s rays, some of the energy is absorbed, and the rest of that energy and heat is reflected back into space. Greenhouse gases in the atmosphere trap the reflected energy, redirecting it back to earth and ultimately contributing to global warming. Various gases play this role, including:[3]

Positives And Negatives Of Global Warming

While some of these greenhouse gases, such as water vapor, are naturally occurring, others, such as CFCs, are synthetic. CO2 is released into the atmosphere by both natural and human causes and is one of the leading contributors to climate change. CO2 is increasing at an alarming rate and has the potential to remain in the Earth’s atmosphere for thousands of years unless absorbed by the ocean, land, trees and other sources. [4] However, as CO2 production continues to rise, the Earth’s natural resources to absorb it are also diminishing. This is already happening in many ways as food resources disappear from things like deforestation. Some studies even predict that plants and soil will be able to absorb less CO2 as the lot continues to warm—perhaps accelerating climate change even more. [5]

Solar activity, as mentioned above, plays a role in Earth’s climate. While the Sun goes through natural cycles, increasing and decreasing the amount of energy it emits to Earth, it is unlikely that solar activity is a major contributor to global warming or climate change. Since scientists began measuring solar energy hitting our atmosphere, there has been no measurable upward trend.[6]

There are many significant ways in which agriculture affects climate change. From deforestation in places like the Amazon to the transportation and livestock needed to support agricultural efforts around the world, agriculture is responsible for a significant portion of the world’s greenhouse gas emissions. However, agriculture is also an area that is making huge strides to become more sustainable. As productivity increases, less carbon is emitted to produce more food. Agriculture also has the potential to act as a carbon sink and can eventually absorb almost the same amount of CO2 it emits. [7]

Deforestation and climate change often go hand in hand. Not only is climate change increasing deforestation through wildfires and other extreme weather, but deforestation is also a major contributor to global warming. According to the Earth Day Network, deforestation is the second leading contributor to global greenhouse gases. [8] A lot
