The climate on the planet is changing. Several lines of evidence demonstrate that our weather, oceans, and ecosystems are changing, including shifts in ecosystem characteristics, like the length of the growing season, the timing of flower blooms, and the migration of birds. The changing temperature and precipitation patterns. Increases in ocean temperature, sea level, and acidity. Changes in the frequency, intensity, and duration of extreme weather events. And, the melting of glaciers and sea ice. These changes are due to a buildup of greenhouse gases in our atmosphere and the warming of the planet due to the greenhouse effect.
Human activities have produced huge volumes of carbon dioxide and other greenhouse gases into the atmosphere since the Industrial Revolution, altering the earth's climate. Natural activities such as solar energy fluctuations and volcanic eruptions also have an impact on the earth's temperature. They do not, however, explain the warming that has occurred over the last century.
By analyzing a variety of indirect climate measures, such as ice cores, tree rings, glacier lengths, pollen remains, and ocean sediments, as well as studying changes in the earth's orbit around the sun, scientists have pieced together a record of the earth's climate. This record shows that the climate varies naturally over a wide range of time scales, but this variability does not explain the observed warming since the 1950s. Rather, human activities are quite likely (> 95 percent) to be the primary source of that warming.
Human activities have contributed substantially to climate change through greenhouse gas emissions and also on reflectivity or absorption of the sun’s energy.
Human activities have caused concentrations of the primary greenhouse gases to rise since the Industrial Revolution. The quantities of carbon dioxide, methane, and nitrous oxide in the earth's atmosphere are presently higher than they have been in the last 800,000 years. These greenhouse gas emissions have enhanced the greenhouse effect, causing the earth's surface temperature to rise. Burning fossil fuels has the greatest impact on the climate of any human activity.
Agriculture, road building, and deforestation, for example, can alter the reflectance of the earth's surface, resulting in local warming or cooling. Heat islands, which are metropolitan regions that are warmer than the surrounding, less crowded areas, exhibit this effect. Buildings, pavement, and roofs reflect less sunlight than natural surfaces, which helps to explain why these regions are warmer. While deforestation can increase global reflectivity by replacing dark trees with brighter surfaces like crops, the net effect of all land-use changes appears to be a slight cooling.
The release of microscopic particles into the air, known as aerosols, can cause the sun's energy to be reflected or absorbed. Aerosols are formed when several forms of air pollutants undergo chemical reactions in the atmosphere. Aerosols produced by humans have a net cooling effect on the earth.
Environmental issues, especially in today’s time, are currently and continuing to destroy our planet through climate change. Climate change is a phenomenal/global phenomenon that affects the climate through different and irregular or not usual or not normal natural occurrences/natural calamities that deals with a great impact and change on the everyday living of humanity on the planet. Now in our society, we start tolerating each other’s wrongdoing that can highly affect everyone around us in different ways including some examples just by simply throwing out non-biodegradable materials, not proper disposal of garbage, using fossil fuels, allowing major factories to proceed with releasing dangerous chemical into the air. These are not even half of all the major issues society is currently doing to our community and to our planet so it’s best for everyone to make a change or BE THE CHANGE in order to lessen the issues of our environment which decreases the life of our planet.
Scientists around the world know how little time we have to reverse the catastrophic effects on our environment and have decided to protest in order to convince the public of how dire the current situation is. The global community must listen to the trained and educated scientists who are trying to show us this startling truth. If we cannot come together even to agree that the evidence proves a need to make a societal and economic change, then we will witness exponentially more destructive climate disasters. Climate change is the greatest danger to all species on this planet, and if we ignore the people who are studying its effects, we stand to destroy thousands of lives.
Following the release of the Intergovernmental Panel on Climate Change's latest report, over 1,000 scientists from 25 nations held demonstrations last week. To avert catastrophic climatic consequences, the research warns that quick and profound reductions in greenhouse gas emissions are required by 2025.
In a letter, the Scientist Rebellion states that "existing activities and plans are fundamentally insufficient, and even these requirements are not being realized," and that their demonstrations "emphasize the severity and unfairness of the climatic and ecological catastrophe," according to the organization's statement.
During rallies last week, scientists from around the world raised similar concerns and called on their governments to take immediate action to combat climate change. Protesters in Washington, D.C. for the Scientist Rebellion were shackled to the White House fence. Spanish scientists splattered artificial blood over the National Congress's exterior. German protestors nailed themselves to a bridge, while Panamanian scientists held demonstrations at several embassies. According to a statement released by the Scientist Rebellion, scientists in Malawi organized a teach-in at Lilongwe University of Agriculture and Natural Resources.
On April 6, the climate scientist was one of seven activists detained (and later released). Their motivation: a severe warning from the United Nations' Intergovernmental Panel on Climate Change that time is running out to reach the world's climate objectives, as documented in a key report released last week.
Protesters from many groups and organizations joined them in large numbers. Climate activist organization Declare Emergency, as well as Indigenous activist groups, Honor the Earth and Camp Migizi, joined Abramoff in Washington. In reaction to the latest IPCC report, Extinction Rebellion, an activist organization pushing for more government action on global threats to the planet's ecosystems and biodiversity, held a series of protests throughout the world last week.
The impacts of human-caused global warming are already occurring, are irreversible on the timeframe of individuals alive now, and will intensify in the decades ahead, according to NASA.
Changes in precipitation patterns, increased droughts and heatwaves, stronger storms, and rising sea levels of between 1 and 8 feet by the end of the century are among the consequences.
According to a February story from 12 News, scientists throughout the world agree that extensive harm to animals, ecosystems, and society is already occurring at a quicker rate than previously expected.
The state of the planet is far worse than most people think. Everything we cherish is in jeopardy as long as fossil fuels heat our globe. One of the most frightening elements of it all for me is the contrast of current and near-future climatic calamities with "business as usual" happening all around me. It's so bizarre that I frequently check the science to make sure it's true, a kind of scientific nightmare arm-pinch.
With a history extending back at least 3,000 years, scientists have long played a vital role in environmental conservation. Based on the earliest scientific findings, many ancient cultures recognized the health impacts of air pollution, mining, soil erosion, biodiversity loss, and other human activities and made steps to ameliorate the effects. Yet, over the years, scientists' pioneering work has sometimes been overlooked, if not mocked, with disastrous results that have been repeated throughout history. The current human tragedy is partly due to governments and companies' reluctance to heed environmental scientists' warnings, increasing the hazards to human health and stifling discoveries and technology that may alleviate those concerns.
