The lies of Global Warming

– Begins now 3×1, hier in Brazil TV. I am Luiz Carlos Azedo and today we will discuss the global warming. Our guest is the physicist and meteorologist Luiz Carlos Molion who questions the theories – let’s say, hegemonic in our days – related with this subject. Participate in this interview the journalist Zilda Ferreira, author of the Blog EDUCOM, which deals with environmental education and the journalist Efraim Neto, moderator of the Brazilian network of environmental journalism. <<The Earth, poetically identified as the Blue Planet, located in the Galaxy Via Lactia, orbits in the solar system and is distinguished by its unique atmosphere. Here, in millions of years life has evolved creating a complex system favorable for the existence of thousands of plant and animal species dependent on a food chain. The human being – extractivist – takes its sustenance from the land and the sea.

To enable the agriculture and industry uses various types of energy, obtained mostly from fossil fuels that generate tens of pollutants. On entering the second decade of the new millennium, the greatest challenge of humanity – that is to produce and develop without altering the atmosphere – presents itself as an emergency agenda for all nations. At the recent climate conference in Copenhagen, it became clear that rich countries, emerging or poor need to speak the same language, if they wish truly – in the medium term – contain the aggressions to the global environment.>> – We will start our interview with a question from a viewer. – Why do you say that there is no global warming? – I contend that there is no global warming because it already occurred in the past periods in which they were warmer than now. For example: If we get to the period of the years 800 to 1200 a.C -called Medieval Warm Period – Temperatures were higher than now and at that time the man not released carbon; not emitted carbon into the atmosphere. The Vikings came from Scandinavia and colonized the northern regions of Canada and southern Greenland and are now frozen regions.

So you can see that, that period was warmer than now. Between 1925 and 1946, there was also a very significant warming, which corresponds to approximately 70% of all this warming that – the people say – occurred in the last 150 years. At that time there was an increase of 0.4 degrees Celsius – between 1925 and 1946 – and that very probably due to increased solar activity in the first half of the twentieth century and the fact that in this period practically not occured any large volcanic eruption, so the atmosphere was clean – transparent – and entered more solar radiation and then increased the temperature. Notice! In 1946, after the second World War, the man threw to the atmosphere less than 10% of the carbon that launches today, so it is very difficult to say that the warming between 1925 and 1946 was due to human action. Later – after the war – that, in fact, there was an increase in industrialization, was emitted more carbon, but what happened? A global cooling between 1947 and 1976 and now this latest.

– Dr. Molion, you were commenting on the case of the Vikings, there is a french historian named Pierre Chani who was an expert of studies on European expansion and he said the Vikings not only conquered America because there was a period – immediately after their arrival, in that Arctic region – of cooling of the earth and there is a stream of scientists who defends a thesis against prevailing opinion – which says that there is a global warming – and say that we are on the verge – if we can use this expression – of a new global cooling. Is it? – Perfect. This period, which lasted more or less until 1250 a.C, was followed by what was called the Little Ice Age, which lasted from 1350 until 1920. I mean, very recent. – You assign to this cooling the barbarian invasions, because they have turned to the continent, because of cooling. – It was just the opposite, ie, the cold period leads to frustrations harvest and hunger. You have paintings made at that time showing that the river Thames was frozen.

Paintings from 1630 – 1650 show that fairs were made ​​over the frozen river. So, if I look at history, I would say this: that in the last million years the Earth has gone through nine ice ages. Each ice age lasts for a hundred thousand years. So nine times a hundred thousand gives nine hundred thousand. In one million, 90% of the time, the weather is colder than now. These ice ages are interrupted by warmer periods called interglacial. That we are living, Luiz Carlos, began about 15 thousand years ago and all of human history is summarized in the last ten thousand years. So we are in a period, as you said, on the eve of a new ice age. In fact we can be within a new ice age, since this our interglacial is already with 15 thousand years, according to paleoclimatic studies. So, there is a variability So, there is a variation upon that very slow fall that will take one hundred thousand years, practically, to get to 8 -10 degrees below what is today. On top of that there is a ripple of half a degree up, half a degree down. If we have that, as I said from 1925 to 1946, had a ripple down, a cooling from 1947 to 1976 – which was very bad for Brazil and around the world under the economic point of view – and now we had a small increase from 1977 to 1998 The “cue ball” now is the cooling.

– Is there a disparity of measuring instruments among the various periods? – Certainly, certainly. No doubt. – Would be the diagnosis today more accurate than before? – The biggest problem is not that, because when you put those long series, 100 -150 years, from cities like Paris, Vienna, Berlin… these cities were growing and if the thermometer was stuck in the same place, at the same meteorological station it would suffer the effects of urbanization. What is this effect of urbanization? Rains. If the area is vegetated, there is infiltration of water. The water evaporates and cools the surface. When the city then becomes urbanized, the asphalt and concrete causes the runoff of the water, that there will fall. So, today the cities do not have water to evaporate and the same heat of the Sun causes higher urban temperatures than its surroundings. São Paulo, for example, on the order of 3 degrees. There are studies here in Rio de Janeiro that show as well – depending on the region – the order of 3 – 4 degrees.

So, the effect that is known as Urban Heat Island interferes in the temperature. The same thermometer, even if it is calibrated will show higher temperatures. There is no way to eliminate this effect of urbanization on the measure. There is no way to eliminate. They say that if you select a basket of thermometers around the world that is located in the big cities, what will happen is the trend these thermometers show an ever increasing temperature. But when you use satellites covering the whole globe, including oceanic regions, it is shown that in the last 20 years a slight decrease occurred. Excluding the peak of El Niño, in 1997 – 1998, as El Niños tend to warm the atmosphere… – But does it not come back now, this year? – But this is pretty weak and must die now in February, maximum in March and will not affect, the contrary, it must turn to the cold La Niña. So, when you look at the data taken by satellites..

. – So will be the next year a cold year? – Yes, with cold winters. This is the trend, frosts in the south and southeast, cold temperatures and for us here, relatively drier during the dry season, ie, in the period from April to October, drier than the normal. – Professor, our scientific validation with respect to climate studies are based on numerical models… – That is it. – …and our system of climate research has evaluated and provided to society certain results. How do you evaluate this? – Well, Efraim. The models are nothing more than computer programs. Some are very sophisticated coming to have thousand lines, one million rows. These models attempt to reproduce the physical processes occurring in the atmosphere, but the atmosphere of the Earth depends on externs physical processes, eg, variation in solar activity, volcanic eruptions, tsunamis or earthquakes influence the heat distribution of oceans and also depends on the oceanic processes, for instance, that are treated very badly in these models, particularly with regard to the transport of heat. A climate model, for example, can not reproduce an El Niño. It can not reproduce this variation It can not reproduce this decadal variation of the Pacific lasting 25-30, where the Pacific warms in the tropics and then turns and cools.

The Pacific occupies 35% of the land surface and the atmosphere is heated from below. So, when the Pacific temperature changes, changes the atmosphere and changes the climate. These models make projections, Efraim, upon hypothetical scenarios that will never happen and the models in itself are disabled. So, for example, if I were to believe in this model, I would like to see this model predicting “the past”. Because of the past I already have data, is not it? And they did it, but the error was very large. The current models can not reproduce past climate. So, I have no guarantee that they will predict future climates, ie, model results are useless and do not lend themselves to planning. – Since the 70s, you have been showing the importance of the oceans in relation to climate, this from a global point of view. Since we are talking about climate change from a general point of view, what is the importance of having more advanced studies in relation to the oceans, since it seems to me that this has been of little relevance in relation to the data applied by the IPCC (Intergovermental of Climate Change)? – You are absolutely right, Efraim.

There is a tendency to leave the oceans outside of this climate control, when in reality they are extremely important to control the weather. We are talking about a planet that is 71% covered of water with an average depth of 3,800 meters, ie, this body of water is a huge heat reservoir that softens the climate change, so that the changes are not so big. The differences remained around more or less half degree up, half degree down thanks to the oceans. Recently we – the scientific community – developed a system of buoys – are more than 3,200 buoys – that are special. They dive up to 2,000 meters deep moving with the sea current for 9 and a half days, after they inflate, through a bladder that they have, and start to rise by measuring temperature and salinity. Arrives at the surface and transmits this data to the satellite. So, this system was completed in 2002 and the analysis of the datas from these buoys shows that the heat content of the oceans is declining.

This means that the global oceans are cooling and this cooling will lead to global cooling, not a warming. So, we have two very important factors: The sun, which has a cycle of 90 years and is now going into decline and will be so until the year 2032 and the oceans, which these buoys indicate that is cooling. These two phenomena that are fundamental; two basic controllers of the climate of the Earth will lead to a global cooling for the next 20 years, which is much worse than a warming..
