- Even a slight change in temperature can change entire ecosystems beyond recovery. An increase in 1°C in just over 200 years has brought about destruction to essential ecosystems that have ensured our survival and now struggle to survive themselves.
- However, the effects of climate change are not just an increase in temperatures globally. It also has its impact on our daily activities – be it energy, transportation, food habits, or the health of ecosystems and biodiversity.
Man – made CO2 has increased by almost a third since the pre – industrial era, which has posed several survival challenges for all living things on the planet and has also brought about geological changes: Melting glaciers, thawing permafrost, warming oceans, intense droughts, storms, and heatwaves, are more intense and frequent than in the past. According to meteorological data, many of the warmest years on record have occurred in the past 20 years.
Human – induced global warming has caused multiple observed changes in the climate system, and an increase in GMST of 1.5°C or more could devastating.
