Introduction

Climate change is one of the severe challenges facing the world today, and its impact has emerged worldwide. Frequent extreme weather events, rising sea levels, and decreasing biodiversity not only threatens the living environment of mankind, but also has a profound impact on global economic and social stability. To address this challenge, governments and businesses have taken action to develop a series of policies and measures to reduce greenhouse gas emissions and promote sustainable development. Among many technologies and means to deal with climate change, Amine-based Delayed Catalysts (ADCs) are an efficient and environmentally friendly material that plays an important role in building insulation, industrial insulation and other fields.

Amine foam delay catalyst is a chemical additive used in the production of polyurethane foam (PU Foam). It improves the performance and application effect of foam materials by controlling the rate of foam reaction and the formation of foam structure. . Compared with traditional catalysts, amine foam delay catalysts have a longer induction period and better temperature adaptability, which can effectively catalyze reactions at lower temperatures while avoiding excessively fast reactions at high temperatures, thus ensuring foam. Material quality and stability. In addition, amine foam delay catalysts also have excellent environmental protection properties, which can significantly reduce the emission of volatile organic compounds (VOCs) and reduce environmental pollution.

Current Situation and Challenges of Climate Change

Climate change refers to the long-term trend of the earth’s climate system, mainly including rising temperatures, changing precipitation patterns, frequent occurrence of extreme weather events. According to a new report from the United Nations Intergovernmental Panel on Climate Change (IPCC), global average temperatures have risen by about 1.1 degrees Celsius since the Industrial Revolution, and this heating rate will continue in the coming decades. The impact of climate change is multifaceted, covering many areas such as natural ecosystems, human social and economic activities, and global health.

First, climate change has caused serious damage to natural ecosystems. Global warming has caused melting glaciers and rising sea levels, threatening the ecological balance and residents’ lives in coastal areas. At the same time, the frequency of extreme weather events such as heavy rain, drought, hurricanes has increased, causing huge losses to industries such as agriculture, forestry, and fishery. Biodiversity is also declining, and many species are at risk of extinction, which not only affects the stability and function of the ecosystem, but also weakens the earth’s ability to self-regulate.

Secondly, climate change has had a profound impact on human social and economic activities. Increased energy demand, intensified food security issues, and damage to infrastructure have all brought tremendous pressure to the global economy. Especially for developing countries, the impact of climate change is more prominent, and these countries often lack sufficient resources and technologies to address the challenges brought about by climate change, which further worsens poverty, hunger, disease and other problems.

After, climate change poses a serious threat to global health. High temperature weather, air pollution, water shortage and other problems have increased health risks such as infectious diseases and cardiovascular diseases. Research shows that climate change may lead to the expansion of the spread of tropical diseases such as malaria and dengue, posing new challenges to the global public health system.

Faced with the severe situation of climate change, the international community generally recognizes that active and effective measures must be taken to mitigate the speed of climate change and adapt to the impacts of climate change. To this end, governments and international organizations have formulated a number of policies and agreements, such as the Paris Agreement and the Kyoto Protocol, aiming to achieve global temperature increase control by reducing greenhouse gas emissions, promoting clean energy, and improving energy efficiency. Within 2 degrees Celsius, even efforts are made to limit the heating to 1.5 degrees Celsius.

However, there are still many challenges to achieve this. First of all, there are technical bottlenecks. Although significant progress has been made in renewable energy, energy-saving technology, etc., there are still technical difficulties in some areas, such as building insulation, industrial insulation, etc., and further innovation and breakthroughs are needed. The second is the cost issue. The research and development, production and promotion of low-carbon technologies and products require a large amount of capital investment. How to achieve environmental benefits while ensuring economic benefits is an urgent problem. In addition, the public awareness enhancement�� is also crucial. Only when all sectors of society fully recognize the harm of climate change and actively participate in response actions can the goals of global climate governance be truly achieved.

To sum up, climate change is not only an environmental issue, but also a major issue involving global sustainable development. In the face of this challenge, we need to start from multiple angles, comprehensively use policies, technology, economic and other means to jointly respond to climate change and protect the earth’s home.
