Human activities have already raised Earth's temperature by 1.1°C, leaving only a tiny window before it crosses the 1.5°C limit that we are aiming for, according to Climate Change. Given recent heatwaves, droughts, unseasonal rains, and other extreme weather occurrences, it also illustrates that the negative effects of climate change are already here.

Everyone is affected by climate change, and every human activity has an impact on our environment. Everyone, from city dwellers who use air conditioners to manufacturing companies, private automobiles, and heavy-duty freight carriers, contributes to greenhouse gas emissions that contribute to global warming. To make people grasp how unmistakably this warming will effect us, we must rise above the inherent inequity between developed and developing countries and identify roles in mitigating climate impacts. Change will occur when people are aware of their responsibilities and feel held accountable.

Installation of rooftop solar, deployment of electric vehicles (EVs), design of energy efficient buildings using compliant materials, increased use of public transportation, better water and waste management, and other integrated actions can effectively drive efficient energy use and emissions reduction in a compact geography. This would also encourage others to do the same.

This change might be accelerated by freight moves from road to rail or inland water transport, as well as passenger movements from short-haul flights to faster trains.

The key players in implementing and leading these actions, however, are a diverse group of stakeholders from various geographies and sectors, including municipal commissioners, city engineers, public transportation operators, mid-level corporate executives, architects, construction contractors, and other actors. Many of these stakeholders in related sectors have only a rudimentary awareness of what climate change is and how they might help. This is due to the fact that only a few people who comprehend the jargon have been allowed to participate in climate debates. Others see it as a mystery, a threat of a future illness that could affect their great-grandchildren.

As delegates gather for COP26 from November 1 to 12, let us hope they recognise that while conversations are necessary for cooperative action, it is now time for the participating countries to act with equal or more intensity.
