Over the last 30 years, there has been a gradual increase in the CO2 level. But what is also observed is that despite deforestation, the planet’s vegetation has grown by about 20%. This expansion of vegetation on the planet, nature lovers largely owe it to the increase in the concentration of CO2 in the atmosphere.
[If we study, however, what has been happening at the geological level for several million years, we realize that the present period is characterized by an extraordinarily low CO2 level. During the Jurassic, Triassic, and so on, the CO2 level rose to values sometimes of the order of 7000, 8000, 9000 ppm, which considerably exceeds the paltry 400 ppm that we have today.
That being said, the recorded rise is 0.8 degrees Celsius and is, therefore, nothing extraordinary. If the temperature goes up, ocean water obviously dilates and some glaciers recede. This is something glaciers have always done, and not a specificity of our time.
Thus, in Ancient Roman times, glaciers were much smaller than the ones we know nowadays. I invite the reader to look at the documents dating back to the days of Hannibal, who managed to cross the Alps with his elephants because he did not encounter ice on his way to Rome, (except during a snow storm just before arriving on the Italian plain).
Still another phenomenon we tend to exaggerate is the melting of the polar caps. The quantity of ice in the Arctic has not gone down for 10 years: one may well witness, from one year to the other, ice level fluctuations, but on average that level has remained constant.
Many other climate myths and legends exist. From storms to tornados, extreme events are going down all around the world; and when they occur, their level is much lower, too.
As explained by MIT physicist Richard Lindzen, the reduction of the temperature differential between the north hemisphere and the equatorial part of our planet makes cyclonic energy much smaller: the importance and frequency of extreme events thus tend to decrease. But once again, the rise of temperatures shows a magnitude considerably lower with respect to that we currently project.
The agreement of the Paris COP 21 was not signed to save the planet and to prevent us from roasting due to an imaginary temperature increase of +2°C. Behind all that masquerade is hidden, as always, the ugly face of power, greed, and profit.
All the industrialists who are in favor of that commitment, which will ruin Europe and immensely impoverish its citizens, do so for the good reason they find in it a huge and easy source of income.
As for NGOs, when they are not simply motivated by greed, their motive consists in a resolutely Malthusian ideology.
Their object is to return the world to a very small population, on the order of a few hundred million people. To do so, they impoverish the world, remove the power of fossil fuel energies, and thus ensure that the number of deaths increases.

We're not going to debate climate change, the existence of it. The Earth is getting hotter. And human activity is a major cause, period. We're not going to give time to climate deniers. The science is settled, even if political opinion is not.
For more than thirty years, climate scientists have been living a surreal existence. A vast and ever-growing body of research shows that warming is tracking the rise of greenhouse gases exactly as their models predicted. The physical evidence becomes more dramatic every year: forests retreating, animals moving north, glaciers melting, wildfire seasons getting longer, higher rates of droughts, floods, and storms—five times as many in the 2000s as in the 1970s. In the blunt words of the 2014 National Climate Assessment, conducted by three hundred of America's most distinguished experts at the request of the U. S. government, human-induced climate change is real—U. S. temperatures have gone up between 1.3 and 1.9 degrees, mostly since 1970—and the change is already affecting "agriculture, water, human health, energy, transportation, forests, and ecosystems." But that's not the worst of it. Arctic air temperatures are increasing at twice the rate of the rest of the world—a study by the U. S. Navy says that the Arctic could lose its summer sea ice by next year, eighty-four years ahead of the models—and evidence little more than a year old suggests the West Antarctic Ice Sheet is doomed, which will add between twenty and twenty-five feet to ocean levels. The one hundred million people in Bangladesh will need another place to live and coastal cities globally will be forced to relocate, a task complicated by economic crisis and famine—with continental interiors drying out, the chief scientist at the U. S. State Department in 2009 predicted a billion people will suffer famine within twenty or thirty years. And yet, despite some encouraging developments in renewable energy and some breakthroughs in international leadership, carbon emissions continue to rise at a steady rate, and for their pains the scientists themselves—the cruelest blow of all—have been the targets of an unrelenting and well-organized attack that includes death threats, summonses from a hostile Congress, attempts to get them fired, legal harassment, and intrusive discovery demands so severe they had to start their own legal-defense fund, all amplified by a relentless propaganda campaign nakedly financed by the fossil-fuel companies.
Over the last 30 years, there has been a gradual increase in the CO2 level. But what is also observed is that despite deforestation, the planet’s vegetation has grown by about 20%. This expansion of vegetation on the planet, nature lovers largely owe it to the increase in the concentration of CO2 in the atmosphere.
Research has shown that increased carbon dioxide has had a fertilizing effect on plants, boosting growth of certain vegetation in some areas over the past three decades.
But after CO2 delivers an initial jolt to some plant life, levels of plant productivity drop as most plants get saturated with CO2. Besides, plants need more than CO2 to grow—like people, they need other nutrients, too. Without an increase in those, growth plateaus.
The real problem is that with more CO2 entering the atmosphere, temperatures will rise, droughts will expand and rain patterns will change. The National Climate Assessment has said these changes will be "increasingly negative on most crops and livestock."

On the one hand, giving up on trying to educate lay people that seem unwilling or unable to understand something that is seems very obvious to the scientists studying it, and just working on the issue is one possible route. I can see how it is much less frustrating, but at the same time, to a degree, the lay people are the ones that hold the purse strings, and are the "boots on the ground" in combating the problem. If you can't bring the average person around to the idea that climate change is real, is happening, and needs to be a focus of our attention, can we hope to take steps in the right direction? I don't see an easy answer.

You also can't underestimate the level of depression that scientists in this field are suffering from. It can be quite debilitating.

Also, if the whole point is a "no climate change" stance, why do those quotes readily admit that climate change is totally normal and natural. It's not a climate change denial stance, it's a "calm down, climate change is normal" stance.

J Grouwstra wrote:it depends somewhat from country to country, but for the country I live in, The Netherlands, there is one goal: Reduction of greenhouse gasses by 49% in 2030 compared to the level of 1990. It mentions specifically that this is the one goal the agreement has, so I wasn't making a personal interpretation.
