What is the main cause of climate change in the world? Is it related to the ozone layer or what?
Human activities,inventions ,discoveroes and ever increasing human population.
Dear Malik N.
The first reason to climate change is the continuously changing of Earth environment (geomorphology, tectonic. etc.); solar activity changing. Same has important role of anthropological activity: pollution of oceans and cutting out the rainforests.

There are several factors responsible for the climatic change, may be anthropogenic reasons play vital role.

TThe current global average temperature is 0.85ºC higher than it was in the late 19th century. Each of the past three decades has been warmer than any preceding decade since records began in 1850.
The world's leading climate scientists think human activities are almost certainly the main cause of the warming observed since the middle of the 20thcentury.
An increase of 2°C compared to the temperature in pre-industrial times is seen by scientists as the threshold beyond which there is a much higher risk that dangerous and possibly catastrophic changes in the global environment will occur. For this reason, the international community has recognised the need to keep warming below 2°C.

The biggest cause is the rapid growth of human population, and the subsequent activities that are related to this growth, the burning of fossile fuel, deforestation, pollution of the marine environment, etc. and etc.
There are as many motive as the number of uses man has for world natural resources. The reasons above are all part of the problem and I found this site which also treats the question in a very easy manner.

Tooooooo much of Carbon foot print !!!!!!!
Industrial disposal and automobile , list is endless !!!
According to some of the previous comments
Climate change is multifactorial, although among the related factors is the reduction of the ozone layer and the increase of carbon dioxide in the troposphere, which causes the so-called greenhouse effect and global warming of the planet.
Industrial development in the past 150 years has led to the release of carbon dioxide-containing gases, the main cause of global warming, which has led to significant and dangerous changes in the Earth's atmosphere, having recently exceeded the Earth's atmospheric concentration by 400 ppm, To raise the planet's temperature by 1.2 ° C.
Greenhouse effect is a phenomenon in which the atmosphere holds some of the sun's energy to warm the planet and keep our climate mild. Carbon dioxide is one of the most important gases that contribute to the doubling of this phenomenon for its production during the burning of coal, oil and natural gas in power plants, cars, factories and others, in addition to deforestation in large quantities. The other greenhouse gas is methane emitted from rice farms, cattle breeding, waste landfills, mining works and gas pipelines. Chlorofluorocarbons (CFCs), which are responsible for the depletion of the ozone layer and nitric oxide (fertilizers and other chemicals), also contribute to this problem because of their heat retention.
I think that climate change can have many reasons, such as the entry of carbon dioxide from human activities into the atmosphere, the exploitation and use of fossil fuels, which leads to global warming and the destruction of forests Which help to remove carbon dioxide.
It is interesting you mentioned the ozone layer. It took 2.5 billion years for the Earth to create the ozone layer (once oxygen gas was produced in the air by microorganisms), but it took just 50 years for humans to partially destroy it (mostly by freon escaping in the air from air conditioners, fridges and the like).
The warmer climate today is caused by burning of fossil fuels, no doubt about it. If one wants to stop the effects (which can be deadly), all one has to do is stop leaking carbon dioxide into the air, (from your engines) as if it was a garbage dump.
I suppose it is related to the CO2 gas where these emissions are heavier than the other air components, which make heat to be trapped.
