This is a complex question that continues to be debated. However, there is a direct evidence of human contribution to atmospheric CO2 emissions from cars and power plants.There are also natural factors that can influence climate including the sun and ocean cycles. Personally, I believe in cause and effect. Humans can limit emission from power plants, develop and use clean energy, and become more responsible in protecting the Earth regardless of the debate.

Dear Sir

Simply, climate change is engendering cultural change.

The climate change is influenced by natural and synthetic contributors. The advancement of technology in this modern era of technology purveys by fossil fuel and deputy energy resources. The end products of such energy resources induce anomalous products into natural balance of ecosystem and environment, certainly, the quantity is more where dominant usage. The adverse impacts of climate change effect on human, animal, plant, insects, water, air, soil, etc.

Thank you Vilemar Magalhaes. Amir

Dear Vilemar Magalhaes,

The man has influence to the climate change! Not so as the politician, and the science writer mentioning .His influence is visible only in that the climate become strongly quickly variable.

Multiple studies published in peer-reviewed scientific journals show that 97 percent or more of actively publishing climate scientists agree: Climate-warming trends over the past century are extremely likely due to human activities. In addition, most of the leading scientific organizations worldwide have issued public statements endorsing this position. The following is a partial list of these organizations, along with links to their published statements and a selection of related resources.

Climate change is a change in the statistical distribution of weather patterns when that change lasts for an extended period of time (i.e., decades to millions of years). Climate change may refer to a change in average weather conditions, or in the time variation of weather within the context of longer-term average conditions. Climate change is caused by factors such as biotic processes, variations in solar radiation received by Earth, plate tectonics, and volcanic eruptions. Certain human activities have been identified as primary causes of ongoing climate change, often referred to as global warming.[1]

Scientists actively work to understand past and future climate by using observations and theoretical models. A climate record—extending deep into the Earth's past—has been assembled, and continues to be built up, based on geological evidence from borehole temperature profiles, cores removed from deep accumulations of ice, floral and faunal records, glacial and periglacial processes, stable-isotope and other analyses of sediment layers, and records of past sea levels. More recent data are provided by the instrumental record. General circulation models, based on the physical sciences, are often used in theoretical approaches to match past climate data, make future projections, and link causes and effects in climate change.

In the context of climate variation, anthropogenic factors are human activities which affect the climate. The scientific consensus on climate change is "that climate is changing and that these changes are in large part caused by human activities,"[68] and it "is largely irreversible."[69]

"Science has made enormous inroads in understanding climate change and its causes, and is beginning to help develop a strong understanding of current and potential impacts that will affect people today and in coming decades. This understanding is crucial because it allows decision makers to place climate change in the context of other large challenges facing the nation and the world. There are still some uncertainties, and there always will be in understanding a complex system like Earth's climate. Nevertheless, there is a strong, credible body of evidence, based on multiple lines of research, documenting that climate is changing and that these changes are in large part caused by human activities. While much remains to be learned, the core phenomenon, scientific questions, and hypotheses have been examined thoroughly and have stood firm in the face of serious scientific debate and careful evaluation of alternative explanations."

Of most concern in these anthropogenic factors is the increase in CO2 levels. This is due to emissions from fossil fuel combustion, followed by aerosols (particulate matter in the atmosphere), and the CO2 released by cement manufacture.[70] Other factors, including land use, ozone depletion, animal husbandry (ruminant animals such as cattle produce methane,[71] as do termites), and deforestation, are also of concern in the roles they play – both separately and in conjunction with other factors – in affecting climate, microclimate, and measures of climate variables.[72]

Climate change is primarily a natural phenomenon. Natural fluctuation and climate change are highly correlated or in other words nature is mainly responsible for climate change.

I feel, that the human activities may have also contribution on the climate change as observed from late 19th century, increase of global temperature about 1oC. But the question is the degree of influence due to anthropogenic activities? Not yet known? The debate lies here.

Lot of deliberations took place or still active on RG. It is observed that experts are divided to justify the causes of climate change - some are in favour of natural variations and others support the human role.

"Science by consensus (opinion?) has never been acceptable or even accurate" (Remark of Dr.Kenneth) - It is always true. Regards

Even the White House has allowed the release of a report concerning emissions, as described in the following article:

https://www.cnbc.com/2017/11/03/white-house-approved-report-concludes-humans-are-behind-climate-change.html

Further, in that article it notes that "extreme weather events" are concerns for agriculture, ecosystems, etc.  -  Sea level rises are, of course, concerning. 

Senad Becirovic noted NASA data in his recommended response above.  Not long ago, I contacted Dr Gavin A. Schmidt, NASA, to find such data used in a New York Times article, and he kindly supplied the following:

Cheers.

Most climate changes.

Towe's approach is the most logical

Yes man induce climate change, especially those who are selfish.

Dear Vilemar

The earth history records many important points in which the climate and geology changes occured without human action, that is refer to presence of natural factors play dynamic changes in the environmental conditions.

In other hand, there are unresponsible human activities destroy the equilibrium of the biosystem and create critical problems in the environment.

Good Luck

A well framed policy to control population; the under developed and developing countries have to be more careful in this aspect in order to secure the minimum needs for good living (mainly food, water and house). The population growth has a prominent role in environmental degradation. Regards

Definitely yes. The ozone layer thinning and the concomitant rise global temperatures are realities

I think the majority of scientists supports the fact that overpopulation has serious impact on environment. Regards

If we look into the various causes of climate change, the answer is yes. Such as:

Deforestation

Ozone depleting substances

Green House Gases

Over Grazing

Population increase
