With the increase of extremely hot days, it is likely that this type of event will occur with greater frequency and intensity.

In 2018, occurred 121 events with more than 80 cm above the medium sea level.The 29 October 2018, we experienced a high tide +156 cm above medium sea level and 12 November 2019 happened a high tide + 187 cm.2019 mean sea level is 35 cm higher, on average, than the value computed at the beginning of the previous century (1870). The maximum increase occurred from 1930 to 1970 due to the combined effects of subsidence and eustatism. After that period, and until 2008, m.s.l. seems to attain a fairly constant value. After 2008 m.s.l. shows again an increasing trend. The increase in the number of high water levels (>110cm) since the sixties is evident. While at the beginning of the previous century we can observe one event with water levels >110 cm per year, in the past years we have, on average, 5-6 event per year. Analogously, the number of events with very low water levels has decreased.For other information, see the web page of the center for Tidal Forecast and Early Warning http://www.comune.venezia.it/it/content/centro-previsioni-e-segnalazioni-maree

In recent years several categories of doctors (among these, pediatricians) have established that there is a connection between air quality and respiratory diseases in the Venice area and across the Po Valley. During the winter season2017/2018/2019, several cities decided to cope with this problem ad signed an "Padan agreement" against air pollution (PM10) due to traffic,transport, biomass combustion for domestic heating and agriculture (spraying of zootechnical slurry). Air pullution is caused also by ship traffic back and fourth from the Port inside the lagoon, from the airport and from motorboat.More informations here http://www.comune.venezia.it/it/content/laccordo-il-bacino-padano

Furthermore, due to the climate changes caused by global heating, the risks of floods and coastal erosion in the territory of Riga city are still growing.Considering the geographical, hydrogeological and climate situation of Riga, the following three main types of natural causes of river flood can be distinguished:1.River flood caused by strong wind.2.Spring river flood.3.Flood caused by intense rainfall and rising groundwater level.In the case of strong northwest storms more often are flooded Rutku island, Mangaļu peninsula, the right bank of Daugava, Daugavgrīva, Bolderāja, areas from Krievu island to Krēmeri un Voleri, Lucavsala island, partly the right bank of Zakusala island as well as other relatively low urban areas.The city of Riga may be threatened by a combination of several causes of flooding, i.e. increased flooding can be caused by a sea surge caused by a storm in combination with a relatively large flow rate in the Daugava. The threat of complex sea storms and spring flooding is present not only in the areas adjacent to the Daugava, but also in the system of branches and lakes – Ķīšezers and Juglas lakes.In the city of Riga, the territories that are threatened by probable floods were identified and which need to be protected due to the inhabitants, cultural and historical values, economic activities, planned development of the territory and historical environmental pollution. Territorial estimation was carried out for the near future climate change scenario, for the period 2021-2050 with a probability of 1% repetition of floods or once every 100 years, and 8 flooding areas that need to be protected from flooding were identified:1.Around the river Buļļupe (Vakarbuļļi, Rītabuļļi, Daugavgrīva, Bolderāja).2.Around Vecdaugava.3.Around Hapaka ditch and Beķera ditch (Krēmeri, Voleri, Spilve).4.Around Ķīšezers lake, Juglas canal, Juglas lake and Baltezers lake.5.Around Sarkandaugava.6.Around Zunda canal (Ķīpsala, Klīversala, Mārupītes downhill).7.Around Bieķen ditch (Mūkusala, Bieķen island, Lucavsala island).8.Around Krasta Street from Salu bridge to Dienvidu (South) bridge.

The decline has been steepest in end-user fuel consumption and in the district heating system 44%.3.During this period electrical power consumption emissions have decreased by 16%, but motor vehicles emissions have decreased by around 8%.4.Most of the emissions in 2020 come from motor vehicles (46,5%) and heat consumption in the district heating supply system (22,3%); whereas the rest of the emissions come from fuel consumption in different consumer sectors (17,3%) and electrical power consumption (13,8%).5.It should be noted, that due to the impact of the COVID-19, reduce of the CO2 emissions in individual sectors wouldn`t have long-term effects.Analysis of CO2 emissions in Riga by emission flow and source leads to conclude that there are four main sources of CO2 emissions: the district heating system, consumption of gas in the end-user sectors, fuel consumption by motor vehicles and electrical power consumption.
