The UN climate report, titled “United Nations Climate Report 2022,” is a timely reminder of our collective responsibility to reduce greenhouse gas emissions. In this article, we look at the impact of climate change on nature and people, and we discuss the evidence that climate action is necessary to prevent further damage. We also look at the alternatives to removing carbon dioxide from the atmosphere. In this article, we consider the impact of climate change on nature and people, and we look at the alternatives to removing carbon dioxide from the atmosphere.
Impacts of climate change on nature
The latest IPCC report lays out the dangers of climate change and its impacts. But it doesn’t tell the whole story. Oil-producing countries wanted to emphasize the positive effects of climate change, such as the benefits of Arctic fishing. The IPCC report is not yet final, but it is an excellent step toward addressing these issues. Nonetheless, the results will still be controversial.
The fifth IPCC Assessment Report released in 2014 revealed a more extensive range of potential impacts of climate change. For instance, increased heat waves, droughts, and floods drive species extinction. Climate change also causes massive shifts in animal distribution, and the timing of critical biological events is changing. Even though the impacts of climate change are not yet fully understood, the report highlights the dire consequences of not only our current emissions but for the future.
Impacts of climate change on people
The impacts of climate change on people are numerous, ranging from food security to access to freshwater. As temperatures rise, people are more susceptible to heat stress, infectious diseases, and other problems associated with climate change. Here are some of the most notable impacts. Among these:
Increasing temperatures are causing extreme heat events to become more frequent and intense, affecting human health, communities, and infrastructure. High carbon dioxide levels, a greenhouse gas, act as a blanket to trap heat, leading to hotter temperatures. Moreover, increased temperatures have been linked with the most severe impacts of climate change, especially for the most vulnerable groups. Extreme heat also increases the risk of illness and death in older age.
There are three primary causes of global warming: human activity, natural disasters, and disease. Carbon dioxide is released when humans burn fuels, and methane emissions come from landfills and agriculture. All of these factors are responsible for the warming we experience today. Global warming since the late 1800s has increased temperatures by 1.1o Celsius. The last decade was the warmest decade on record. But climate change is not inevitable. People must take action and make informed choices to protect their health and welfare.
Alternatives to removing carbon dioxide from the atmosphere
The main problem with the high deployment of carbon dioxide removal is that it leads to peak-and-decline behavior of global temperature. However, this trend is driven by the perception that carbon dioxide removal is an economically optimal way to meet a finite carbon budget. It is based on the idea that carbon budgets fill up gradually over time, but the availability of net carbon removals makes this assumption invalid. Instead, a different carbon price trajectory should be chosen.
One promising approach is direct air carbon capture. It involves capturing CO2 from the air and storing it underground. This method could help combat climate change by reducing emissions of carbon dioxide. Researchers have studied the efficiency of five CO2 capture configurations in eight locations, and their study suggests that direct air carbon capture is more effective than burying CO2 underground. The proposed method of CO2 capture has the potential to reduce global emissions of carbon dioxide significantly.
Evidence of climate action
This year’s IPCC report presents new components, including a chapter on-demand, services, and social aspects of mitigation. This new section discusses how society can reduce the consumption of high-emitting goods and services and how these measures complement sectoral chapters. This chapter also examines how technological innovations can help reduce carbon emissions. The IPCC report also highlights society’s role in climate change mitigation and provides an overview of the best practices around the world.
In August, the UN Climate Report released the first part of AR6 explaining how climate change affects the planet. The second part focused on its impacts and suggested ways in which countries can mitigate climate change. The report said that current emissions levels would lead to a 14% increase in global emissions by 2030, with disastrous consequences for humans and nature. Government delegations met virtually during the two-week approval process and spent 150 hours debating the text. Ultimately, however, countries were unable to agree on the language for the report, which prompted the document’s rejection.
