Is the climate changing and if so who s responsi ble Scientists interpret the increasingly large number of extreme weather events as clear signs of progressive climate change Mojib Latif an internationally acknowl edged climate expert at GEOMAR Helmholtz Center for Ocean Research in Kiel Germany takes an unmistak able stand on the issue Climate change in the form of a warming of the Earth is taking place and humans are the main cause This has been scientifically proven For instance the five year period from 2014 to 2018 was the warmest around the globe ever since the first large scale temperature measurements were made in 1880 By how many degrees has the Earth warmed compared to the pre industrial age Latif explains So far global warming has amounted to one degree centigrade The ef fects are already obvious The ice of the Earth is melting the sea levels are rising and extreme weather events are increasing worldwide Other experts and organizations such as the Intergovernmental Panel on Climate Change IPCC have made similar estimates 0 8 to 1 2 C of human caused global warming Shocking statistics illustrate the need for action Ac cording to a UN report 6 457 weather disasters between 1998 and 2017 killed more than 600 000 people and in jured 4 1 billion The financial damage during that period amounts to 1 9 quadrillion euros Is the Paris Agreement with the internationally binding target of limiting global warming to clearly below two degrees centigrade versus the pre industrial level an all clear signal Latif analyzes the agreement critical ly The Paris Agreement did not produce the expected impetus In 2018 worldwide greenhouse gas emissions reached another all time high Ever since the topic of climate protection has been on the agenda emissions of the most important greenhouse gas carbon dioxide have virtually skyrocketed Since the early 1990s they in creased by about 60 percent Who s causing the greenhouse gas emissions Accord ing to the most recent IPPC survey worldwide it s the energy sector 35 forestry and farming 24 in cluding climate harmful methane and nitrous oxides industrial operations 21 transportation 14 and buildings 6 This is how compliance with the two degree limit can be achieved According to projections the global emissions of greenhouse gases by 2050 would have to be reduced by 40 to 70 percent versus 2010 By 2100 emissions would have to be at near zero or below What does the expert propose Latif explains The fu ture belongs to renewable energies and alternative drive systems The future belongs to digitalization and decen tralized energy supply Countries that fail to pursue these developments run a risk of no longer playing in the pre mier league The climate problem can only be resolved by all countries together So as far as this goes all countries are also required to take part in climate protection Blam ing each other does not help the climate CLIMATE CHANGE Sources Temperature NASA CO2 Carbon Dioxide Information Analysis Center CDIAC 20052000 2010 2015 2018 Temperature increase in degrees centigrade CO2 emissions in gigatons year 0 7 0 8 0 6 0 9 0 5 ALONG WITH CO2 EMISSIONS TEMPERATURES RISE 30 35 25 Humans are the main cause of global warming Prof Mojib Latif GEOMAR Helmholtz Center for Ocean Research Kiel global 21
