The Earth is a dynamic sphere and the climate of the planet, that is, global weather conditions, is also unstable. Not surprisingly, there are many myths about what happens in the atmosphere, in the ocean and on land. Let’s see what scientists have to say about some of the global warming claims.
Even before the advent of SUVs and technologies that produce greenhouse gases, the Earth’s climate was changing. Humans are not responsible for today’s global warming.
Climate change in the past suggests that our climate depends on the amount of energy that comes in and goes out. If there is more heat than the planet can give off, the average temperature will rise.
The Earth is currently experiencing an energy imbalance due to CO2 emissions, hence the greenhouse effect. Climate changes in the past only prove its sensitivity to CO2.
What kind of warming are we talking about if there are snowdrifts in my yard. How is a harsh winter possible in the face of global warming?
The air temperature in a particular area has nothing to do with the long-term trend of global warming. Such fluctuations in weather only mask changes in the climate as a whole. To understand the big picture, scientists rely on the behavior of the weather over a long period of time. Looking at the data of recent decades, you can see that record highs in temperature were recorded almost twice as often as lows.
Global warming has stopped and the Earth has begun to cool.
Period 2000-2009 was the hottest according to observations of meteorologists. There were strong snowstorms and abnormal frosts. Global warming is compatible with cold weather. For the climate, long-term trends, decades of years, are important, and these trends, unfortunately, show warming on the globe.
During the last hundreds of years, solar activity, including the number of sunspots, has increased, as a result, the Earth has become warmer.
Over the past 35 years, the sun has tended to cool and the Earth’s climate to warm, scientists say. In the past century, some increase in global temperature could be attributed to solar activity, but this is an insignificant aspect.
In a study published in the journal Atmospheric Chemistry and Physics in December 2011, it was said that even during a long break in solar activity, the Earth continues to warm up. It was found that the surface of the planet accumulated 0.58 watts of excess energy per square meter, which was released back into space during 2005-2010, when solar activity was low.
До сих пор нет консенсуса относительно того, имеет ли место потепление на планете.
About 97% of climatologists agree that global warming is occurring as a result of human activity. According to the website Skeptical Science, in the field of climate research (as well as with the help of related sciences), scientists have stopped arguing about what causes climate warming, and almost all of them have come to a consensus.
Rick Santorum summed up this argument in the news when he said, “Is carbon dioxide dangerous? Ask the plants about it.
While it is true that plants absorb carbon dioxide through photosynthesis, carbon dioxide is a serious pollutant and, more importantly, the greenhouse effect. Thermal energy coming from the Earth is captured by gases such as CO2. On the one hand, this fact keeps the heat on the planet, but when the process goes too far, the result is global warming.
A number of opponents point to the history of mankind as evidence that warm periods are favorable for development, while cold ones led to catastrophic consequences.
Climatologists argue that any positives outweigh the negative impacts of global warming on agriculture, human health, the economy and the environment. For example, according to research, warmer weather will increase the growing season in Greenland, which means water shortages, more frequent wildfires and expanding deserts.

There is a difference between land and sea ice, scientists say. Climatologist Michael Mann said: “In terms of the Antarctic ice sheet, there is an accumulation of ice due to warmer and wetter air, but less ice at the periphery due to the warming of the southern oceans. This difference (net loss) is projected to turn negative within decades.” Measurements show that sea levels are already rising due to the melting of the ice mass.
