Climate Change: The Defining Crisis of Our Time | Frenly Directory

Climate change refers to the long-term warming of the planet due to an increase in average global temperatures, primarily caused by human activities such as burning fossil fuels, deforestation, and land-use changes, which release large amounts of greenhouse gases like carbon dioxide and methane into the atmosphere. The consequences of climate change are far-reaching, from rising sea levels and more frequent natural disasters to altered ecosystems and unpredictable weather patterns. According to NASA, the past four years have been the hottest on record, with 2020 being the hottest year globally, at 1.02°C above the 1961-1990 average. The Intergovernmental Panel on Climate Change (IPCC) warns that in order to limit global warming to 1.5°C above pre-industrial levels, global CO2 emissions must reach net-zero by 2050. The climate crisis has become a highly politicized and contentious issue, with some countries and corporations resisting calls to reduce emissions and transition to renewable energy sources. As the world grapples with the challenges of climate change, it is clear that the next decade will be crucial in determining the course of human history, with the potential for either catastrophic consequences or a transformative shift towards a more sustainable and equitable future.
