Some progress in containing fires in Los Angeles The firefighters with the support of helicopters would have been able to contain the fires that are devouring the vegetation in mountainous areas north of Los Angeles, we are talking about tens of thousands of people authorized to return to their homes (evacuation orders had reached over fifty thousand and many remain with alert notices), while a fire in the southwest of Ventura County is worrying since the vegetation is quite dry due to eight months of absence or little rainfall and the so called Santa Ana winds could advance the flames quickly. In the meantime the death toll from previous fires is twenty-eight with fourteen thousand structures destroyed, then barriers are being prepared in hilly areas (near Palisades and Altadena) in the event of any rains that would drag a flow of debris downstream. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Jan 24, 2025

 Assessments of U.S. exit from climate agreements After China the United States is among the countries that emit the most climate-altering gases into the atmosphere, but in first place if we consider the historical total of these greenhouse gases emitted; so some protest about the exit of the U.S. from the Paris climate agreements, then this happens just when California has recorded the worst forest fires in its history (and currently Texas is affected by an anomalous cold wave at these latitudes). Countries quite affected by climate change such as Iran, Libya and Yemen have also not joined the agreements; so in part the same considerations can be made. It is estimated that the cuts in greenhouse gas emissions would have to be forty percent by 2030 and almost sixty percent by 2035 to be able to limit warming that would make the planet unlivable. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Jan 22, 2025 n°: 5854 Low temperatures in parts of Canada and northern U.S. Weather forecasts announce very low temperatures in Canada in the coming days due to arctic air influences, although meteorologists say that it is not really a polar vortex (which allows, by stationing high up in the atmosphere, to generally maintain low temperatures in polar areas and therefore its weakening); but there is also talk of up to minus forty degrees Celsius in areas north of Alberta due to icy winds and about minus forty-five in parts of Saskatchewan, Manitoba, Ontario and Quebec, then some say that the perceived temperature could perhaps be up to minus fifty-eight. Low temperatures are also expected in large areas in the north of the United States even if with values that are not so low, but still dangerous for health if you stay outdoors for a long time, it seems that it could also partially affect northern Florida. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Jan 18, 2025 n°: 5851 Little snow accumulated in the Alps It is estimated that on average there is up to more than sixty percent less snow in the Alps than in the past (a period calculated approximately from 2011 to 2023), this means that the water reserve in the summer months will be very reduced and how it would be appropriate to build reservoirs to collect water from any rainfall in the spring months in order to fill the water deficit. The situation on the Apennines is a little better thanks to the recent snowfalls which, if they have caused some inconvenience with falling trees and difficulty moving, allow water reserves to be stored in the snowpack, but also in this case in the event of periods characterized by above-average temperatures in the coming months, it would be necessary to intercept the meltwater of the snow in special reservoirs; in fact, the phenomenon of desertification affects increasingly large areas. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Jan 16, 2025 n°: 5849 Preventing fires to limit damage The fires that are devastating the hills of Los Angeles with a provisional toll of twenty-four victims, several serious injuries and calculations of the extensive damage raise questions about what interventions to take to limit the damage in case a similar situation could theoretically also occur in other areas of the world affected by climate change; in fact, adequate prevention could avoid significant disasters. Some say that for example sufficient water reserves must be available to feed the hydrants (it seems that in the Palisade area there was no pressure when the firefighters arrived), then pay attention to possible triggers of fires such as fireworks that remain on the ground as well as dry brushwood and dried plants, make sure that fires cannot spread quickly by tracing firebreak avenues. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Jan 13, 2025 n°: 5846 Monitored the overheating trajectory Every month in 2024 has been the heat or the second highest since global temperatures began to be monitored, some speak of an incredible trajectory (if for example we look at the trend since 1940), while others argue that it is necessary to verify the anomaly in decades to confirm it; but by now it would seem clear that with a concentration of carbon dioxide in the atmosphere of 422 parts per million, it is illusory to think that in a few decades the situation regarding global warming will improve. The planet is steadily well above one and a half degrees Celsius of average temperature, a value that had already been indicated as a limit not to be exceeded in order not to have to suffer the disastrous effects of extreme weather phenomena; however there is talk of possible potential to change this trajectory by exiting the era of fossil fuels. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Jan 10, 2025 n°: 5844 A fire devours the hills of Los Angeles Strong gusts of wind make it difficult and almost impossible for firefighters to take action as they try to deal with a practically uncontrollable fire that has advanced rapidly in the hills of Los Angeles forcing tens of thousands of people to leave their homes, there is talk of many houses destroyed (..two victims and several wounded) and about thirteen thousand structures threatened by fires. It is expected that the wind may intensify at night and continue for days, forming vortices with gusts that can reach one hundred and sixty kilometers per hour. Half a million users are at risk of being left without electricity supply with over twenty-eight thousand already in the dark. Changing the subject but remaining on naturalistic issues to report the difficult situation of the localities affected by the earthquake in the Everest area due to the cold, then there is talk of almost two hundred injured. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Jan 08, 2025 n°: 5842 High number of fires in the Amazon in 2024 Last year the Amazon rainforest recorded the highest number of fires in seventeen years, then there are months of intense drought that have fueled the fires, forty-two percent more than in 2023; however if calculate from satellite observations the total area that went up in smoke seems to be the lowest in years. The Brazilian authorities said they would commit to the protection of Amazon forests also in view of the COP30 conference in November in the city of Belem in the Amazon. Away across South America last month suffered from a severe drought, at least according to data collected from a European atmospheric monitoring service. The columns of smoke that emanated from the fires reached great distances, carrying soot to large cities such as Brasilia, Rio de Janeiro and San Paulo. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Jan 03, 2025 n°: 5839 Systems for better tsunami prevention The warning systems currently installed around the globe to warn the population of the arrival of a potentially disastrous tsunami would not be entirely efficient, at least as far as a check carried out on the signal buoys that have batteries that last about two years and need to be replaced is concerned. Only fifty percent of the buoys were operational although apparently enough to operate the system that was designed to provide coverage even in these cases, but some argue that better prevention would be needed; then the systems are sometimes outdated as technology, this twenty years after the Banda Aceh disaster and the tsunami caused by a magnitude 9.1 earthquake in the Indian Ocean with consequent waves over thirty meters high that literally swept away entire villages leaving signs that are still visible. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Dec 27, 2024 n°: 5834 Desertification in alarming increase It is estimated from the data of a new study that one billion and two hundred thousand people and an area of about one and a half billion hectares larger as the size of Antarctica is affected by desertification with unreassuring forecasts for the future. To cope with desertification, almost two hundred countries recently attended a COP16 conference in Riyadh in Saudi Arabia, but with little results about the discussions held by the United Nations to combat desertification (UNCCD) and this after a whole series of conferences for example on biodiversity in Colombia, on reducing the use of plastic in South Korea, on the financing of countries affected by climate change in Azerbaijan with in practice little light and many shadows. Needless to say that without interventions the fertile soil it will become progressively less and less productive and this will have significant consequences on the displacement of populations and the cost of food. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Dec 21, 2024 n°: 5831 Various and natural * The author doesn't assume some kind of responsibility for the bad use of the articles councils (all rights are reserved) |
