Climate change refers to the long-term alteration in Earth's climate, primarily due to human activities such as burning of fossil fuels, deforestation, and other human activities that increase the levels of greenhouse gases in the atmosphere. These gases trap heat and cause the planet's average surface temperature to rise, leading to global warming.

The Intergovernmental Panel on Climate Change (IPCC), a body of the United Nations, has stated that the warming of the planet's average temperature is unequivocal and primarily due to human activities. This warming is causing a range of impacts on the natural world, including melting glaciers and sea ice, rising sea levels, more frequent and intense heatwaves, increased frequency and severity of extreme weather events such as hurricanes, droughts and floods, and shifts in the ranges of plants and animals.

The impacts of climate change are already being felt around the world, and will likely continue to worsen in the coming decades unless substantial and sustained action is taken to reduce greenhouse gas emissions. This requires a transition to cleaner energy sources and the implementation of policies to conserve and protect forests and other carbon sinks, as well as individual actions to reduce personal carbon footprints.

Addressing the challenge of climate change will require a sustained global effort and collaboration between governments, businesses, and individuals. It is important that we act now to limit the severity of future impacts and protect the planet for future generations.

Addressing climate change involves reducing greenhouse gas emissions, adapting to the impacts of climate change, and preserving and restoring ecosystems that can absorb carbon. Some strategies to reduce emissions include transitioning to renewable energy sources, improving energy efficiency, reducing deforestation, and developing carbon capture and storage technology.

Rising sea levels are a result of melting ice caps and glaciers, and can result in increased coastal flooding, erosion, and salinization of freshwater sources. In some areas, rising sea levels can displace coastal communities and threaten infrastructure and property.

The point at which climate change becomes irreversible is difficult to predict, but many scientists believe that we are already experiencing irreversible impacts. To prevent further irreversible damage, it is important to take immediate action to reduce emissions and transition to a low-carbon economy.

Businesses can play a crucial role in combating climate change by reducing their carbon footprint, investing in renewable energy, and advocating for policies that address climate change. Businesses can also improve their sustainability practices, such as reducing waste and emissions, conserving water, and promoting sustainable procurement. Additionally, companies can take steps to build resilience to the impacts of climate change and support communities affected by it.
