According to climate skeptic sites, human impact on the environment is minimal.
In addition, some claim that carbon dioxide in nature is alarmingly low. That it would increase is just fine.
This is one of the most common claims from the so-called climate deniers. According to Science and Education, the average climate skeptic claims that man cannot influence the climate and that the work to solve the problems is meaningless.
Many climate deniers claim that uncomfortable scientists who go against the tide are silenced for spreading “uncomfortable truths”.
“What would be inconvenient with a scientific theory that shows that we humans can continue to emit unlimited carbon dioxide into the atmosphere, however, has not really been clarified.
Claim 1: Scientists exaggerate the climate threat
No. The researchers are cautious in this context and usually lie at the bottom. They avoid presenting the worst-case scenario so as not to risk being exaggerated.
Claim 2: Scientists do not agree on global warming
Climate skeptics argue that because even scientists do not agree that there is climate change, we do not need to do anything. This on the theme: If it’s not broken, don’t fix it. Well, the researchers are certainly in agreement. To claim that global warming is underway is not an opinion. There is no doubt that it is we who increased the greenhouse gas and made the earth warmer.
Claim 3: The climate has changed in the past
The climate deniers point out that we had both ice age and the Mediterranean climate in the Baltic Sea, without people emitting greenhouse gases. The climate has changed in the past without human participation. But now we are involved in the system. And our impact is greater than the natural causes of climate change right now. So what does it mean that the average temperature increases by 2 degrees? 2 degrees doesn’t sound much, but it’s half an ice age, though in the other direction. The average temperature on earth was 3 to 5 degrees colder during the last ice age. A few degrees make a big difference when it comes to climate.
Claim 4: It is the sun’s fault that it gets warmer
In the last hundreds of years, the number of sunspots has increased. This has resulted in the climate becoming warmer, some say.
No, the sunspots vary with a periodicity of 10-15 years. It looks like ripples on the temperature measurements, but cannot explain that it has become a degree warmer in a hundred years.
Claim 5: There is no danger, nothing will happen
Yes. Lots of things happen. If it is not enough for nature to change, the risk of conflicts will increase when people are forced to hike, for example as a result of flooding or flooding. Low-lying land will be flooded. Cities such as Mumbai and Miami run the risk of being submerged. The dams around the Netherlands will not suffice and cities like Miami fall underwater.
Claim 6: The animals will adapt
Some animals and insects will appreciate a warmer climate. For ticks, it will be easier to survive, but agriculture and forestry will be hit greatly affected by the pests. But most people are disadvantaged by changes. They have found a niche during the 1000 years but the climate has been relatively stable. Plants and animals are good at adapting. An adaptation for some means that they die out. We lose a great deal of diversity.
Claim 7: The temperature has not risen since 1998
At the same time as carbon dioxide emissions increased during the period 1998-2005, this did not affect the temperature. Nothing has happened since 1998, despite all warnings, some climate skeptics say.
1998 was an unusually hot year. Almost 15 years later, it could be said that the temperature leveled off. But it is “cherry-picking”, you choose the year that best serves your purpose. You have to look at the whole trend. If scientists wanted to use the same tactics, they would measure from 1997 which was much cooler. But the argument is no longer used because both 2014 and 2015 and 2016 were significantly warmer than 1998.
Claim 8: Carbon dioxide has no significance for climate change. The big culprit is the steam
Climate deniers often show diagrams showing how little carbon dioxide is in the atmosphere and that water vapor is the major culprit. The water vapor is short-lived in nature and falls out like dew in the morning, its variations depend on what temperature it is. Those who make a difference are the long-lived greenhouse gases such as carbon dioxide, methane nitrous oxide, and freons. They act as a lever on the steam. A little extra carbon dioxide creates even more water vapor.
Claim 9: The ice is growing on Antarctica
Climate skeptics claim that more ice is being formed on the South Pole, Antarctica. They claim that more ice is being created in eastern Antarctica than is disappearing from the west. Both yes and no. In Greenland, it gets warmer and the ice melts. At the same time, it is snowing more than before, precisely because of the mild climate.
Statement 10: The carbon dioxide content has reached a saturation
This is because it does not matter how much carbon dioxide we emit. It cannot cause more damage.
The claim is that it does not matter how much carbon dioxide we release, we have reached “saturation”. It cannot cause more damage. This statement does not take into account that air pressure decreases with height.
The greenhouse effect is that the sun’s rays heat the earth and heat is radiated from the earth. If we had no greenhouse gases at all, the heat would quickly dissipate into the universe and the earth would be about 18 degrees cold. But because of the greenhouse gases, some of the heat radiation is reflected in the gases and stays in the earth’s atmosphere. With more greenhouse gases in the atmosphere, more of the energy radiates back to the earth and this occurs from a level where carbon dioxide has not reached saturation.
