Myths About Global Warming. Global warming is the process of changing the global average temperature of the atmosphere and oceans. The accumulation of high concentrations of greenhouse gases in the atmosphere blocks the heat emitted by the Sun and traps it at the Earth’s surface, increasing the Earth’s average temperature.
Despite the subject worrying scientists, a lot and being strongly discussed by scholars around the world, there are still several myths that circulate in society. With that in mind, we prepared a list of 10 statements that you have probably heard about the phenomenon but that is not true.
10 Myths About Global Warming
- Global warming is not caused by human action
The consensus is not 100%, but it is close to it. The Union of Concerned Scientists analyzed at least 10,000 scientific articles and found that more than 97% of them refer to human activity as the main cause for the phenomenon.
- Planting trees can be the solution to global warming
The greater the emission of carbon dioxide into the atmosphere, the greater the number of trees needed to absorb the gas. According to experts, if emissions continue to grow, there will be no room on Earth for so many forests.
- Climate change lies only in the increase in CO2
According to Skeptical Science, as global temperatures rise, warming seas release CO2 into the atmosphere. In this way, the planet gets warmer and causes the seas to release even more CO2. Climate change was triggered by human activities, but the rise in CO2 did not precede the rise in temperature. It is more in the sense of being a side effect than the actual cause of climate change.
- The warming of the planet is only the result of human action
Scientists say that the Earth is always subject to temperature changes, regardless of human action. The process may be linked to astronomical factors, such as increased solar radiation, changes in sea currents and the movement of tectonic plates. This does not rule out human actions as fundamental for the intensification of this phenomenon.
- “It’s colder this year, so global warming is getting better”
When Arctic temperatures rise, winter air travels south. Changing weather patterns affect atmospheric winds, which send priceless air to North America and Europe. This is why so-called “climate changes” occur, as the warming trend changes weather patterns and this can even cause cold snaps in places where it is not common.
- The use of fuels such as ethanol is the solution to environmental problems
The use of ethanol, a fuel derived from sugar cane, considerably reduces pollution, but it would have to be produced on a large scale. Specialists warn of the risk of plantations taking the place of forests, woods and areas destined for food production.
- Wind and solar farms are expensive and inefficient
It’s a common belief that renewable energy is expensive, but solar has been the cheapest form of power generation for a long time. Wind on land equals gas, and wind power is now cheaper than nuclear. According to the World Wide Fund for Nature (WWF), renewable energy costs have fallen faster than any other.
- Forests are the great “lungs” of the planet
According to scientists, algae in the oceans are responsible for most of the absorption of carbon dioxide released into the atmosphere.
- Global warming stopped in 1998
In the early 2000s, models created by scientists did not align with what was actually happening with global temperatures. During this period, the climate was still warming not as quickly as the projection predicted it would. Is that because global climate change wasn’t happening anymore? Not. It is likely that the phenomenon happened due to the variability of the Earth’s natural climate.
- Areas close to industries are most affected
Although industrial areas emit more pollutants than others, the greenhouse effect is global. Scientists say that oceanic regions have lower temperatures than populated regions, but attribute the difference to changes in populated areas.
