Topic: What are the causes of climate change? - page 12. (Read 1643 times)

To my opinion great deal of human acting, very reckless human acting and some smaller part of nature cycle.
We are on the road to destroy ourselves if something serious isn't done very soon. Species are disappearing, ice is melting and many are still not aware how dangerous this is. Profit is still something that people like the most, no matter if we endanger ourselves.

Climate change is a long term shift in the weather conditions identified by changes in temperature, precipitation, winds and other indicators. It is one of the defining issues of our time. It is now more certain than ever, based on many lines of evidence, that humans are changing earth's climate.

A lot of factors could cause climate change. First there are natural factors such as calamities and natural disasters which could affect the climate. Next and more common are the man made effects like incorrect disposal of garbage and other kinds of activities that abuses the planet which could lead to pollution.

The cause of climate change are the dynamic processes on the Earth, external influences, such as fluctuations in the intensity of solar radiation, and, more recently, human activity.

We need a shield powered by the sun, and the stronger the sun is, the stronger the shield becomes.

Climate change is happening right now at all the planets in this solar-system, so we can say the Sun is in an active cycle causing all of this.

Humans are increasingly influencing the climate and the earth's temperature by burning fossil fuels, cutting down rainforests and farming livestock.
This adds enormous amounts of greenhouse gases to those naturally occurring in the atmosphere, increasing the greenhouse effect and global warming.
Some gases in the Earth's atmosphere act a bit like the glass in a greenhouse, trapping the sun's heat and stopping it from leaking back into space.
Many of these gases occur naturally, but human activity is increasing the concentrations of some of them in the atmosphere.

The only constant... is change.

That's true about life. And it's true about the climate. The climate has been constantly changing since the earth was formed 4.6 billion years ago.

For example, in just the past 2000 years, we have seen the Roman Warm Period, when it was warmer than today...Then came the cooler Dark Ages... Followed by the Medieval Warm period, when it was at least as warm as today... Then we had the Little Ice Age -- that drove the Vikings out of Greenland. And, most recently, a gradual 300-year warming to the present day. That's a lot of changes. And, of course, not one of them was caused by humans.

During the past 400,000 years there have been four major periods of glaciation -- meaning that vast sheets of ice covered a good part of the globe -- interrupted by brief interglacial periods. We are in one of those periods right now. This is all part of the Pleistocene Ice Age which began in earnest two and a half million years ago. It's still going on, which means that we are still living in an ice age. That's the reason there's so much ice at the poles. Thirty million years ago the earth had no ice on it at all.

So, then, what about carbon dioxide, the great villain of the Global Warming alarmists? Where does that fit in to this picture? Not as neatly as you might think.

Temperatures and carbon dioxide levels do not show a strong correlation. In fact, over very long time spans -- periods of hundreds of millions of years -- they are often completely out of sync with each other.

Over and over again, within virtually any time frame, we find the climate changing -- for reasons we do not fully understand. But we do know there are many more factors in play than simply the concentration of CO2 in the atmosphere -- factors such as the shape and size of the earth's elliptical orbit around the sun, activity from the sun, and the amount of wobble or tilt in the earth's axis, among many others. Even the relatively short 300-year period from the peak of the Little Ice Age to the present has not been steady. The latest trend has been a warming one, but it began nearly a century before there were significant carbon dioxide emissions from burning fossil fuels. And, there has been no significant warming trend in the 21st century. Contrary to media headlines, the trend over the past couple of decades has been essentially flat.

Meanwhile human-caused CO2 emissions are higher than ever. About 25 percent of all the CO2 emissions from human sources have occurred during this period of no net warming.

So, what are we in for next? Will the temperature resume an upward trend? Will it remain flat for a lengthy period? Or, will it begin to drop? No one knows. Not even the biggest, fastest computers.

The car gas, the factory pollution and some other stuffs,i think.

A get factor us the depletion if the ozone layer. It can never be overemphasized. Ice caps are melting, extreme temperatures and climate change. I just hope people take this thing seriously.

Carbon dioxide deposits in the atmosphere that led to the hole on
our ozone layer, pollution on a industrial scale, vehicular emissions,
the burning of natural fuels and deforestation. All of these greatly
contributed to global warming that resulted in climate change
throughout the past 100 years or so.

No need to mention about it again. Everyone knows about it. Even those who deny it agrees with the findings in private, but for their own vested interests they try to argue that there is no such thing called global warming. We need to make a lot of sacrifices, if we need to prevent the situation from worsening any further. But some people are not ready to make these sacrifices.

The rise in the globalwarming due to pollution give rise to greenhousegases which leads to climate change.Deforestation leading to cutting down of forests is another main cause of climate change.Pollution is the main overcome of climate change,the over use of vehicles,the smogs coming out of the chimneys also leads serious problems to our climate.

The world's leading climate scientists think human activities are almost certainly the main cause of the warming observed since the middle of the 20th century.

The main reason why there's climate change is us people. People abused our nature, all we do is just to consume and we don't even know how to take care of Earth. We invent things that are harmful to our planet, we pollute our planet, and we don't stop consuming all it's natural resources.

I think carelessness of men who has given the authority of God the take charge of his creation is one of the major causes of climate change. Some people abused the earth that brought us to unnecessary situation. We are the ones who'll suffer for our recklessness. We must be the one to take care of our environment but unfortunately, we are the ones to blame.

Carbon dioxide is the primary reason for global warming. But everyone is ignoring another major culprit, that is methane. Methane in same quantity as CO2 causes almost 1,000 times the global warming as CO2 does. Fortunately for us, methane is only produced at very low levels. But the polar thawing can change everything. Methane trapped in the permafrost can be released in to the atmosphere.

The changing climate was happening due to the high quanlity of CO2 and poisons that people are releasing to the environments. Mother natural can't take it anymore and punish back to the human.

I think the main cause of climate change is global warming. Because of people not caring for our mother nature, people being irresponsible makes it even worse.

Too many human's crimes was made to the naturals. Kill many species, cut all the trees, dump garbages into the ocean. The climate was changing into the human's trash bin and that's where we gonna live if you're not protecting this planet.
