IPCC Synthesis Report Review Reveals Imminent Danger: We're Headed Towards 1.5°C!

The most recent Synthesis Report from the Intergovernmental Panel on Climate Change (IPCC) is the most exhaustive scientific assessment of climate change to date. The report summarises the findings of previously published working group reports and emphasises the urgent need for action to combat the climate crisis. Based on the analysis of thousands of scientific studies and data, the report concludes that human activities cause climate change on Earth. In addition, the report highlights the profound effects of these changes on the natural world, including biodiversity, ecosystems, and human societies.

The statistical impact of climate change on the environment and human society is significant. Increasing water scarcity and its implications for food production is one of the most glaring effects. Changes in precipitation patterns brought about by global warming have resulted in floods and droughts.

These extreme weather events have negatively impacted crop yields, livestock productivity, and the fishing industry, leading to food shortages in certain regions. In addition to posing a substantial risk to human health and well-being, climate change poses a significant environmental risk. Due to the rising global temperature, extreme weather events such as heatwaves, hurricanes, and wildfires have become more frequent and intense. These occurrences have been linked to higher mortality rates, particularly among the elderly and vulnerable populations. In addition, infectious diseases such as malaria and dengue fever are projected to increase in many parts of the world due to changes in temperature and precipitation patterns.

According to the report, there is still hope that mainstreaming effective and equitable climate action now will reduce losses and damages, given that options exist to reduce GHG emissions that are both feasible and effective and can provide co-benefits. In addition, addressing the challenges posed by global warming requires integrating actions to reduce emissions with measures to adapt to climate change. The effects of climate change impact human health, subsistence, and the environment as a whole. Therefore, it is essential to implement measures that provide broader benefits while simultaneously reducing emissions.

Options exist to scale up climate action, although we still require 3 to 6 times the current climate investment and sufficient global financing to reduce emissions rapidly in cases where developing countries require external funding to meet adaptation needs. Nevertheless, there are multiple feasible and effective options are available now to reduce greenhouse gas emissions and adapt to human-caused climate change. "Mainstreaming effective and equitable climate action will not only reduce losses and damages to nature and people, but it will also provide broader benefits," said Hoesung Lee, chair of the Intergovernmental Panel on Climate Change. "

This Synthesis Report emphasises the need for more ambitious action and demonstrates that, if we act now, we can still ensure a livable, sustainable future for all. In 2018, the Intergovernmental Panel on Climate Change (IPCC) highlighted the unprecedented scale of the challenge required to limit warming to 1.5°C. Due to increased greenhouse gas emissions, this problem has become even more significant five years later. However, the pace and scope of actions taken thus far and current plans are insufficient to combat climate change.

Over a century of fossil fuel combustion and inequitable and unsustainable energy and land use have resulted in a 1.1°C increase in global temperature above pre-industrial levels. This has resulted in more frequent and intense extreme weather events, which have had increasingly dangerous consequences for nature and people in every region of the globe. Every degree of warming accelerates the escalation of threats. Intensified heatwaves, heavier precipitation, and other weather extremes exacerbate threats to human health and ecosystems. People are dying in every region due to the extreme heat. In addition, food and water insecurity due to climate change is expected to increase as global temperatures rise. When risks combine with other negative occurrences, such as pandemics or wars, they become more challenging to manage.

Losses and damages stand out. The report, which was approved during a week-long session in Interlaken, brings into sharp focus the losses and damages we are currently experiencing and will continue to experience, particularly impacting the most vulnerable populations and ecosystems. However, taking the appropriate actions now could result in the transformational shift necessary for a sustainable and equitable global society. Aditi Mukherji, one of the 93 authors of this Synthesis Report, the final chapter of the Panel's sixth assessment, stated, "Climate justice is crucial because those who have contributed the least to climate change are disproportionately affected." "Almost half of the world's population resides in regions extremely susceptible to climate change. In highly vulnerable areas, the death toll from floods, droughts, and storms has been 15 times higher over the past decade, "She continued. In this decade, rapid adaptation to climate change is required to close the gap between current adaptation and what is required.

Keeping global warming below 1.5°C above pre-industrial levels requires deep, rapid, and sustained reductions in greenhouse gas emissions from all sectors. If warming is to be limited to 1.5°C, emissions should decrease now and be reduced by nearly half by 2030. Clear way ahead the solution lies in climate resilient development. This entails integrating measures to adapt to climate change with actions to reduce or prevent greenhouse gas emissions that provide broader benefits. For instance, access to clean energy and technologies improves health, particularly for women and children; low-carbon electrification, walking, cycling, and public transportation enhance air quality, health, employment opportunities, and equity. The economic benefits of improving air quality for people's health would be comparable to or possibly even more significant than the costs of reducing or avoiding emissions. However, climate-resilient development becomes increasingly difficult with each degree of warming.

Therefore, the decisions we make in the coming years will significantly impact our future and that of future generations. To be effective, these decisions must be grounded in our varied values, worldviews, and knowledge, including scientific knowledge, Indigenous Knowledge, and local knowledge. If barriers are swiftly eliminated, there is enough global capital to reduce greenhouse gas emissions. To achieve global climate objectives, increasing financing for climate investments is essential. Governments play a crucial role in minimising these obstacles through public funding and clear investor signals. Additionally, investors, central banks, and financial regulators can play a role.

Some tried, accurate policy measures can achieve deep emission reductions and climate resilience if scaled up and implemented more broadly. Adequate and equitable climate action requires political commitment, coordinated policies, international cooperation, ecosystem stewardship, and inclusive governance. Every community can reduce or eliminate carbon-intensive consumption if technology, know-how, and appropriate policy measures are shared and adequate funding is available immediately.

At the same time, we can prevent rising risks, especially for vulnerable groups and regions, by investing heavily in adaptation. Climate, ecosystems, and society are linked. Approximately 30 to 50 per cent of the Earth's land, freshwater, and ocean must be adequately and equitably conserved to ensure a healthy planet. Urban regions present an opportunity for ambitious climate action that contributes to sustainable development on a global scale. Changes to the food industry, electricity, transportation, industry, buildings, and land use can help to reduce greenhouse gas emissions. Simultaneously, they can facilitate low-carbon lifestyles, improving health and well-being.

By improving the population's health and standard of living, this can also be accomplished. This can be achieved by promoting sustainable agriculture, which reduces greenhouse gas emissions while improving soil health and crop yields. It may also involve providing clean water and sanitation, which improves health and reduces the need for wood and charcoal to boil water. Reducing poverty and hunger is an additional strategy for achieving broader benefits. This can be achieved by adopting economic growth and development-promoting practices. Investing in renewable energy and energy-efficient technologies, for example, can create new job opportunities while reducing the consumption of fossil fuels that contribute to climate change.

This strategy may also include promoting sustainable forest management, which can generate income for rural communities while conserving forests and reducing carbon emissions. Reducing emissions and adapting to climate change also require clean energy, water, and air. Renewable energy sources such as wind, solar, and hydropower are becoming more affordable and accessible, which can aid in reducing carbon emissions and providing affordable, dependable energy. Clean water and air are also necessary for adapting to climate change because they help prevent the spread of waterborne and respiratory diseases, which are frequently exacerbated by climate change.
