@T.Rick Das stimmt nicht. Jahrhunderetkatastrophen sind events, die nur alle 100 Jahre passieren. Das hat nichts mit der Opferanzahl zu tun. Auch ein schlimmer sturm, der niemanden tötet, kann ein jahrhundertevent sein.
Guck dir das hier mal an:
Wikipedia: Climate change in the Middle East and North AfricaDiese Region ist gigantisch,also naher Osten und Nordafrika. Wenn sich da die Temperaturen um nur 1.5 Grad erwärmen, wird ein großer Teil davon vollkommen unbewohnbar:
The IPCC project average global temperatures to rise more than 1.5 degrees by the end of the 21st century.[9] MENA has been identified as a hotspot for future temperature changes due to its arid environmental conditions.[26] Whilst projected rates of warming during winter months are low, the region is expected to experience extreme temperature increases during summer.[27][28] Temperature rises are expected to be further amplified by reductions in rainfall and the associated depletion of soil moisture, limiting evaporative cooling.[29] As a result, heat extremes are expected to increase significantly in both frequency and intensity across the MENA region. According to studies published by the Max Planck Institute for Chemistry, the number of very hot days in the region has doubled between the 1970s and the time when the report was published (2016).[27] The study further projects that heatwaves will occur for 80 days of the year by 2050 and 118 days of the year by 2100.[27] Combined with increased sandstorms associated with longer drought periods, predicted temperature rises would make large parts of the region uninhabitable.[27]
The average maximum temperature during the hottest days of the past 30 years has been 43 degrees Celsius.[10] Dutch atmospheric chemist Johannes Lelieveld has projected that temperature maximum's could reach almost 50 degrees Celsius under current climate scenarios established by the IPCC.[29] Johannes Lelieveld further projects that average summer temperatures are expected to increase by up to 7% across the MENA region, and up to 10% in highly urbanised areas.[29] Extreme heat has been identified as a serious threat to human health, heightening an individuals' susceptibility to exhaustion, heart attack and mortality.[30] Climate scientist Ali Ahmadalipour has projected heat-related mortality rates within the MENA region to be up to 20 times higher than current rates by the end of the century.[31]
Bei nur 1.5 Grad ist das schon so, dass da wohl mehr als 1/3 der Tage bis 2100 Dürre herrschen wird, und schon bis 2050 80 Tage Dürre im Jahr.
Städte die Alexandria werden im Meer untergehen.
Increasing water insecurity as a result of climate change is set to exacerbate existing food insecurities in the countries affected.[43] A study published by the World Food Porgramme has predicted a decline in crop yields by 30% in 2050 as a result of increasing droughts.[43] North African countries are highly vulnerable to reduced precipitation as 88% of the regions crops possess no irrigation, relying on consistent rainfall.[44] The consequences of these reduced harvests strongly impact rural regions and communities that rely heavily on agriculture as a source of income.[45]
In North Africa, Egypt is expected to be most affected by changes in sea level.[47] A third of the Nile Delta and large parts of Alexandria, Egypt's second largest city, lie below the mean global sea level.[49] These areas have been drained for agricultural purposes and undergone urban development, where inundation and flooding is prevented by sea walls and dams.[49] However, failures occurring in these structures, storm surges and extreme weather events could lead to the inundation of these areas in the future if sea levels continue to rise.[49] Agricultural areas in Egypt are particularly at risk, where a one-metre rise in sea level would submerge 12-15% of the nations total agricultural land.[50] This is estimated to displace 6.7 million people in Egypt and affect millions more who rely on agriculture for income.[50] A more moderate 50 cm increase in sea level has been projected to displace 2 million people and generate US$35 billion of damages.[51]
Man wird da auch nur noch sher spärlich irgendetwas anbauen können. Millionen von Menschen, allein in Ägypten (und an anderen Orten natürlich auch) werden auf der Flucht sein, weil sie dort nicht mehr leben können.
Bei 1.5 Grad. Und nur dort. Andere regionen der welt sind natürlich ebenfalls betroffen und es wird dort genauso aussehen, wie in Indian, China, Südamerika oder dem Rest von Afrika, aber auch Südeuropa.
Bei dem beste case, 1.5 Grad, den wir wohl schon gar nicht mehr erreichen können. Während wir auf eine 3 Grad Welt zusteuern, und es wegen herbeifantasierter (weil nicht wissenschaftlich fundierter) wirtschaftlicher Ängste und allerlei ausreden einfach zulassen wollen.
Findest du das nicht dramatisch?
