Not solely. There is a natural greenhouse effect that is supported by the earth's carbon and water cycles. This has kept the earth warm enough for life for millions of years.
However, humans have been burning fossil fuels since the beginning of the Industrial Age (1750s). This releases long-held carbon dioxide that has been sequestered away for 300 thousand years. This extra greenhouse gas is changing the greenhouse effect into an enhanced greenhouse effect, which is causing global warming and climate change.
When Earth's orbit elongates due to factors like orbital eccentricity, temperatures can fluctuate but not solely due to this factor. Other factors such as solar radiation, greenhouse gas levels, and volcanic activity play a significant role in determining global temperatures.
Yes, the Dust Bowl was primarily caused by a combination of natural drought conditions and poor farming practices, rather than being solely a man-made environmental disaster.
The formation of hotspots, where a plume of hot magma rises from the mantle to create volcanic activity, is an event that cannot be fully explained by the movement of lithospheric plates. These hotspots can occur within a plate rather than at plate boundaries, suggesting a deeper source of heat that is not solely related to plate tectonics.
Carbon dioxide (CO2) is a powerful greenhouse gas. In the atmosphere it captures the sun's heat and warms the planet. This is part of the natural carbon cycle. Additional carbon dioxidecomes from burning fossil fuels (coal, oil and natural gas). This CO2 has been hidden underground for millions of years so its presence is an extra burden that the carbon cycle cannot manage.A:Carbon dioxide is a naturally occurring greenhouse gas. In previous concentrations, it helped maintain global temperatures at a level that is comfortable for humans and other animals that have adapted to the present climate. Increases in carbon dioxide levels in the atmosphere are resulting in global warming, by trapping more heat. The planet Venus offers an extreme example - although its orbit is close to that of the Earth, Venus has a surface temperature that would melt lead, because its atmosphere consists mainly of carbon dioxide. In the very long term, concentrations have fallen below these levels, but always coinciding with Ice Ages. A very good demonstration of this come from an ice core two kilometres long and equivalent to 150,000-year record of warmth, cold and warmth, that a French-Soviet drilling team at Vostok Station in central Antarctica produced in 1985, a complete ice age cycle. They found that the level of atmospheric CO2 had gone up and down in remarkably close step with temperature throughout the length of the core.The CO2 levels in the Vostok Station record got as low as 180 parts per million (ppm) in the cold periods and reached 280 in the warm periods, but never higher. But in the atmosphere over the ice, the level of the gas had already reached 350, far above anything seen in this geological era, and is now around 380 ppm.From the time of the Industrial Revolution, things began to change, slowly at first, then gradually more quickly, especially after 1970. Using isotope comparisons for C12, C13 and C14 ratios, scientists have proven that the increase from 260-280 ppm to the present 390 ppm of atmospheric carbon dioxide is entirely due to human activities.A:Global warming is a slow but steady rise in earth's temperatures and is caused, largely, by increase in greenhouse gases, of which the major human contribution is carbon dioxide. The greenhouse effect warms the atmosphere and is caused by atmospheric carbon dioxide. Photosynthesis consumes carbon dioxide tending to counteract greenhouse effect.A:The Earth is much like a greenhouse where the gasses produced by the plants will stay in the greenhouse to create a much more moist and humid atmosphere. Heat from the sun comes in as visible light.Heat escapes as infra-red radiation (invisible light)If they balance, THEN the temperature of the Earth stays constant.Carbon dioxide tends to block the infra-red radiation, less heat escapes, and so the planet gets warmer.A:One of the more interesting issues that is often ignored in most discussions is the saturation issue of carbon dioxide. The first 20 ppm in our atmosphere make up most of the induced warming from carbon dioxide. After the first 150 ppm or so, the ability of carbon dioxide to increase temperature by itself become almost nill. (see Lindzen-Choi graph in related link). The doubling of CO2 from the 190 to 380 ppm has followed this trend and seen less then a degree (C) of overall warmth. Doubling again, using this graph, will see almost no additional heating of the planet according to this concept.
No, sugar does not contain sodium. Sugar is composed solely of the molecules glucose and fructose. Sodium is a separate mineral that is not naturally present in sugar.
No, there is a natural greenhouse effect which has kept the earth warm for millions of years. By burning fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity, humans are causing the enhanced (or accelerated) greenhouse effect which is causing global warming.

Whoever caused the injury should be held liable for it. If your friend did something reckless, which caused the injury, then your friend is solely responsible.
Yes, and no it contributes but dosent solely effect you.
genetic drift is the change in genes due solely to chance.bottleneck effect and founder's effect are both examples of how chance effects the genes.
There isn't one, the colour change on a chameleon is solely based on it's mood
NO, emphysema cannot be solely blamed on a person's lifestyle. Emphysema is caused by any of a number of lung irritants, which affect the alveoli and trigger the production of excess phlegm.
