Another indication of the climate change is the observation that Australia experienced the hottest day ever. Despite this and a multitude of other signs, the backward-looking politicians like the Australian prime minister thwart any actions to combat climate change. President Trump lists as one of his major achievements “cancellation of the unfair and costly Paris Climate Agreement”.
The discussion about climate change has concentrated on coal and oil use in energy production and on eating meat. Also flying and rain forests have attracted much media attention. It is seldom mentioned that the size of the human population is a problem, and actually makes the populistic solution of going back to the past impossible. In the past that the backward-looking leaders want to return to, there were two-three billion people, now we are about eight billion. With two-three billion people, limits to growth had not been reached, now they have. The importance of unicellular algae of the ocean in generating the oxygen balance by photosynthesis is often not acknowledged. Yet, almost half of the oxygen-generating photosynthesis is carried out by these small algae. Finally, one of the important carbon dioxide sources is concrete building – it accounts close to ten percent of the present carbon dioxide emissions.
Thus, one should stop building using concrete and steel. Most of the carbon dioxide emissions are due to cement production, an indispensable component of concrete. Making brick or stone houses would already be much better than concrete. However, the pest alternative would be wooden houses. Technologies are already available, which enable building multi-store houses. Further, the probability of burning of wooden houses is much reduced from 19th century, when whole cities could burn. In a wooden house the carbon would be stored for its entire life length, up to several hundred years. Thus, if all new buildings were wood-based, the carbon footprint of building sector would decrease for 10 % of world total to 0. This would be a huge win in combatting climate change, and could be reached with the presently available techniques. In view of this, one must ask: why is it not done?

President Trump is calling liberal media enemies of the people. At the same time the Trump government is scrapping the agreements that have been made to limit the production of toxic effluents and greenhouse gases. This happens at a time that the effects of greenhouse gas emissions are clearly seen in Northern Hemisphere. Although individual weather events cannot be associated with climate change, this time the accumulation of different phenomena has occurred in so many different places that there can only be one conclusion: enemies of the people are not the ones that report what is happening but the ones, who decide to neglect all the warning signals, and remove or weaken the emission standards as well as promote the use of fossil fuels.
The Californian wildfires are to some degree worsened by the extreme heat and drought - several people have already died. Extreme heat has been the plague of people in Europe, China, South Korea, Japan, parts of North America and parts of North Africa - altogether one can estimate that there have been several hundred heat-related deaths across the world. This is the first time ever that extreme heat has occurred simultaneously in all the continents of the Northern Hemisphere. Storms and heavy rains have already killed hundreds of people, and droughts in other places similarly.
Thoughts and prayers are offered to the mourners of the victims of weather-related deaths by the government, which acts in many ways to worsen them. While other governments could also be doing much more than they are, at least they are not saying that the whole climate change is "fake news".
Isn't the enemy of the people the government that neglects the evidence that is seen by everyone except them and acts in ways that may worsen the situation causing human deaths.
