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.

To address climate change, there are several strategies being proposed and implemented, including:

Reducing greenhouse gas emissions: This can be done through transitioning to clean energy sources such as wind, solar, and hydro power, improving energy efficiency, and reducing emissions from deforestation and other land use practices.

Carbon Capture and Storage (CCS): This involves capturing carbon dioxide emissions from power plants and industrial processes and storing them underground instead of releasing them into the atmosphere.

Adaptation: This involves preparing for and adapting to the impacts of climate change that are already underway, such as sea-level rise and increased frequency and intensity of extreme weather events.

Protecting and restoring carbon sinks: This involves conserving and restoring forests, wetlands, and other ecosystems that absorb carbon dioxide from the atmosphere.

Rising sea levels can affect coastal communities and infrastructure through increased coastal flooding, saltwater intrusion into freshwater supplies, and erosion. It can also lead to the displacement of people, loss of wildlife habitat, and decline in fisheries.

At this point, it is difficult to say when climate change will be irreversible. However, scientists have warned that if greenhouse gas emissions continue to increase at the current rate, the impacts of climate change could be severe and widespread, potentially leading to the extinction of many species and the displacement of millions of people.

Businesses can play a critical role in combating climate change by reducing their own greenhouse gas emissions, investing in renewable energy and energy efficiency, and advocating for policies to address climate change. They can also collaborate with governments and civil society organizations to address the challenge. However, more needs to be done to ensure that businesses are held accountable for their actions and that they are taking meaningful action to address climate change. For example, mandatory disclosure of greenhouse gas emissions, as well as increased investment in renewable energy and energy efficiency, could be areas for improvement.
