Scientists have studies Earth's climate changes for decades, by analyzing many indirect measures of climate such as ice cores, tree rings, glacier lengths, pollen remains, and ocean sediments, as well as by studying the change in Earth's orbit around the sun. This study shows the climate system changes over time over a full range time scales. However, before the Industrial Revolution in the 1700s can be explained climate change by natural causes, such as changes in solar energy, volcanic eruptions, and natural changes in greenhouse gas concentrations. Recent climate changes cannot be explained by natural causes alone. The study indicates that natural causes are not only influenced our climate change in the 21st century.
Climate change has been occurring over the decades but it is just getting worse and more greenhouse gases are getting trapped in the atmosphere and trapping heat energy from the sun along with it. If humans are so small and can create a mess so big we can clean it up too because it is evident that humans have caused an increase in chemicals and pollution that has altered the chemical composition of the atmosphere which ultimately causes the climate change we see
Although some skeptics around the world believe that climate change is a hoax and unscientific, many respected scientists have concluded that environmental changes brought around by humans have altered the patterns of rainfall around the world, resulting in serious consequences. Narration Climate change itself is a manmade alteration to the earth’s natural homeostasis. By instigating climate change, humans have made it so a wide variety of problems have become apparent. One of many complications is the change in precipitation patterns, which can lead to flooding via extreme storms and can even cause extreme droughts. This problem is a serious one as every year, billions of
As a result, heat from the sun is trapped in the atmosphere and making the planet really hot. Since 1880, the global temperature has been increasing. Many people know that the Earth is warming due to the greenhouse gases, and this is true. Although global warming increases the temperature of Earth’s surface, global warming does more apart from warming the Earth’s surface. It changes the climate, raises the sea level, affects the nutrition of plants, and causes more extreme weather.
However, the impacts of human activities have led to abnormal fluctuations of these parameters against the background values. Some of the prominent evidence of climate change includes the increase of global mean surface air temperatures over the land and oceans, the remarkable increase of atmospheric CO2 concentrations globally and ocean acidification. In this report, the mitigation
Overall global warming will impact life on earth in many ways but the extent of the change is largely dependent on human activities as scientist have shown that human emissions of greenhouse gases are pushing global temperatures up. It can therefore be concluded that climate change is the long-term averages and variations in the weather over a long period of time were as anthropogenic climate change relates to the effects human activities have on the greenhouse gases and as the greenhouse gases are long-lived, therefore the planet will continue to warm and changes will happen in the future, but the degree to which global warming changes is up to the human activities affecting climate
The most significant effect of global warming is temperature change. Global warming causes the climate system become warmer. The rise of temperature in global average air and ocean temperature, large amount of snow and ice have melted, and the increases level of sea water are the evidences of warmer climate system. According to Haldar (2011), temperatures on land increased twice faster than the ocean temperatures this shows that different part of the global temperature changes differently. The temperature on land increase faster than the ocean due to the high heat capacity of the sea water in addition of the process of evaporation occurs on the ocean surface help to reduce the
This is changing the natural systems that take place in our atmosphere. When all these extra gases are released, carbon dioxide stars to accumulate in the atmosphere. Climate change is a global issue because when the temperature of the Earth changes even very slightly, it can cause droughts and our crops can die. This is affecting our food supply. Also, when water levels rise even slightly, it can be very destructive for
Oceans rising, temperatures vary, record level floods, historic droughts, tsunamis, and devastating hurricanes; BOOM! The Earth has gone wild. Scientific evidence suggests that these changes are due to climate change. Climate change is an alteration in the usual temperatures, and weather of a region. The signs that climate change affects our one and only earth clearly show up in the oceans and atmosphere.
Throughout the course of history the earth’s climate has dramatically, changed within the last 650,000 years, there has been seven cycles of glacial advance and retreat. “In the past two decades, the scientific community has reached an overwhelming consensus those human activities are causing changes to the global climate.” (David B. Resnik). There has been a massive increase production of carbon dioxide, methane, and other greenhouse gases in the last century that has caused the climate change around the world. “If humanity does not start significantly reducing greenhouse gas emissions, average global temperatures will likely increase by several degrees Celsius in the next fifty years, which would lead disastrous environmental consequences, such as flooding of coastal areas, increased numbers of powerful hurricanes, desertification, decreased agricultural productivity, and loss of biodiversity.” (David B. Resnik). The main driver of today’s warming is the combustion of fossil fuels.
