What Meat-Eaters Must Know
The United Nations Intergovernmental Panel on Climate Change (IPCC) presented an expert survey report, "Global Warming of 1.5 ºC" in 2018, explaining the impacts of global warming of 1.5 °C above pre-industrial levels. The report pointed out that the increase in global average temperature will pose threat to climate change, sustainable development and efforts to eradicate poverty.

In addition, the IPCC also released a report in Geneva on August 8, 2019, citing a study by the World Resources Institute, a Washington-based think tank. It notes that on average, beef requires 20 times more land and emits 20 times more greenhouse gases per unit of edible protein than basic plant proteins.Hence, the report concludes that gravitating toward “balanced diets, featuring plant-based foods” would hugely help the climate change cause.

The following is a list of the possible hazards caused by global warming of more than 1.5 ° C:
The report states that if land can be used more effectively and reasonably, it can better absorb the carbon dioxide produced by humans.

  • Human activities are estimated to have caused approximately 1.0°C of global warming above pre-industrial levels, with a likely range of 0.8°C to 1.2°C. Global warming is likely to reach 1.5°C between 2030 and 2052 if it continues to increase at the current rate.
  • Warming from anthropogenic emissions from the pre-industrial period to the present will persist for centuries to millennia and will continue to cause further long-term changes in the climate system, such as sea level rise.
  • On land, impacts on biodiversity and ecosystems, including species loss and extinction, are projected to be lower at 1.5°C of global warming compared to 2°C. Limiting global warming to 1.5°C compared to 2°C is projected to lower the impacts on terrestrial, freshwater and coastal ecosystems and to retain more of their services to humans (high confidence).
  • Depending on future socioeconomic conditions, limiting global warming to 1.5°C, compared to 2°C, might reduce the proportion of the world population exposed to a climate change induced increase in water scarcity by up to 50%.
  • There is substantial evidence that human-induced global warming has led to an increase in the frequency, intensity and/or amount of heavy precipitation events at the global scale (medium confidence), as well as an increased risk of drought in the Mediterranean region (medium confidence).
  • Climate-related risks to health, daily life, food security, water supply, human security, and economic growth are expected to increase at 1.5 ° C in global warming, and more so at 2 ° C.
  • Of 105,000 species studied, 6% of insects, 8% of plants and 4% of vertebrates are projected to lose over half of their climatically determined geographic range for global warming of 1.5°C.
  • Pathways limiting global warming to 1.5°C with no or limited overshoot would require rapid and far-reaching transitions in energy, land, urban and infrastructure (including transport and buildings), and industrial systems (high confidence).
