The global climate crisis is an urgent problem affecting various parts of the world. With rising global temperatures, extreme weather phenomena and changing climate patterns, the impact of this crisis is becoming increasingly apparent. Global warming, caused by greenhouse gas emissions, causes significant changes in weather and ecosystems. In the Arctic, sea ice is experiencing drastic reduction. According to NASA data, about 13% decline in sea ice occurs every decade. This impacts local species such as polar bears which depend on the ice for hunting. In addition, Arctic warming causes extreme weather in other parts of the world, such as snowstorms and heat waves in Europe and North America. In Indonesia, the climate crisis has resulted in an increase in the frequency of floods and droughts. The Meteorology, Climatology and Geophysics Agency (BMKG) reports that rainfall is changing, causing uncertainty in agriculture. Farmers experience losses due to crop failure, which has an impact on food security in this country with a population of more than 270 million people. Small island nations such as the Maldives and Tuvalu are threatened by rising sea levels. Currently, several islands are experiencing severe coastal erosion, causing communities to experience displacement. Mitigation projects, such as embankment construction and reclamation, are being considered to address this threat. In the United States, forest fires are becoming more frequent due to rising temperatures and prolonged dry seasons. California experienced the largest wildfires in its history in 2020, with more than 4 million acres burned. Smoke from these fires significantly worsens air quality, causing health problems for many residents. Europe is also affected by this crisis. The extreme summer caused a heat wave, with countries such as Spain and France recording temperatures reaching 40 degrees Celsius. In addition, European countries are starting to adapt to renewable energy, seeking to reduce dependence on fossil fuels and targeting carbon neutrality by 2050. Marine ecosystems are experiencing serious impacts due to global warming. Coral reefs, which are important for marine biodiversity, are threatened with bleaching due to rising temperatures and ocean acidification. This disrupts the lives of marine animals and impacts the livelihoods of fishermen around the world. The climate crisis also increases the risk of conflict. Resources such as water and land are becoming scarcer in some regions, fueling tensions between communities that share those resources. Countries like Sudan face social and political challenges due to water scarcity, which worsens the humanitarian situation. Transformation towards sustainability is important to overcome this crisis. Investments in environmentally friendly technologies and increased public awareness can accelerate needed changes. Global movements such as “Fridays for Future” invite young people to get involved in the fight against climate change. Overall, the global climate crisis is a complex phenomenon that affects many aspects of life. From its impact on ecosystems to the challenges humans face, every part of the world is feeling the consequences. Collaborative efforts are needed to create solutions that can slow or even reverse this trend before it is too late.
