What is climate change? Is it the same as global warming? What are its main causes and consequences?

GREENHOUSE EFFECT

Climate change is a global challenge that has no borders and to combat it requires coordinated work by all countries. In these pages, we tackle the subject from an objective, scientific viewpoint , discussing the causes and consequences of climate change and how it should be tackled. One of the MOST amazing video's and explinations on climate change. The main cause of climate change is global warming, which has many negative consequences on physical, biological and human systems, as well as other effects. Carbon dioxide, Methane, Nitrogen oxide, HCFCs : caused mainly by the burning of fossil fuels in electricity generation, transport, heating, industry and construction. Also caused by livestock, agriculture mainly rice farming , wastewater treatment and landfills among others. The forests and rainforests are disappearing at breakneck speed.

For the warming over the last century, there is no convincing alternative explanation. Global data show that was the warmest year on record and the third consecutive year for record global average surface temperatures. The emission of greenhouses gases GHGs , 6 which move about in the atmosphere, is a major cause of global climate change. Even with drastic GHG reductions, almost half of humans will face deadly heat. Although a number of U. Recent developments, however, have diluted federal efforts.

Although the scientific process is always open to new ideas and results, the fundamental causes and consequences of climate change have been established by many years of scientific research, 1 are supported by many different lines of evidence, and have stood firm in the face of careful examination, repeated testing, and the rigorous evaluation of alternative theories and explanations. This chapter provides a brief overview of some basic facts about the risks posed by climate change see Box 2. Earth is warming. Warming has also been observed specifically in the lower atmosphere 3 and the upper oceans.

List of 10 Human Causes of Global Warming for Without major societal changes over the next decade, the planet will face a global environmental catastrophe that will cause or worsen war, poverty, water shortages and massive species die-offs, or so says a dire report issued in fall While the Intergovernmental Panel on Climate Change report was shocking and disturbing, all hope is not lost. Because humans are negatively impacting the environment, it would stand to reason, then, that we could generate a positive impact by altering some of our behavior. The first step is understanding how, exactly, our actions have created this situation.

During the course of global warming, the energy balance and thus the temperature of the earth change, due to the increased concentration of greenhouse gases, which has a significant impact on humans and the environment. It is not scientifically possible to assign individual weather events to the current climate change, however, it can be statistically proven that global warming will increase the probability of extreme weather events. The indirect consequences of climate change, which directly affect us humans and our environment, include:. As the global climate is a highly interconnected system that is influenced by many different factors, the consequences usually result in positive or negative feedback effects. This refers to developments that are self-enhancing due to the occurrence of certain conditions. A common example is the ice-albedo feedback, which refers to the melting of the polar caps.


The burning of these fuels produces gases like carbon dioxide, methane and nitrous oxides which lead to global warming. Deforestation is also leading to warmer temperatures. The hazard of global warming is continuously causing major damage to the Earth's environment.


List of 10 Human Causes of Global Warming for 2020

Global warming is expected to have far-reaching, long-lasting and, in many cases, devastating consequences for planet Earth. Global warming , the gradual heating of Earth's surface, oceans and atmosphere, is caused by human activity, primarily the burning of fossil fuels that pump carbon dioxide CO2 , methane and other greenhouse gases into the atmosphere. One of the most immediate and obvious effects of global warming is the increase in temperatures around the world. The average global temperature has increased by about 1.

Jump to navigation. And yes, it's really happening. Over the past 50 years, the average global temperature has increased at the fastest rate in recorded history. And scientists say that unless we curb global-warming emissions, average U.
