Air conditioning and refrigeration have direct link to climate crisis and are considered as enemies.
For millions of years, humans have survived the extremities of nature without conditioning the air. If so, can’t we survive the present climate change without air conditioners? Theoretically yes, but attitudinally difficult, for it’s no more air conditioning that is the challenge, it is the human conditioning.
Air conditioning and refrigeration have direct link to climate crisis and are considered among the enemies of nature. A few decades ago, AC was installed where it was inevitable, but today it is projected as a necessity, which is a myth driven by the consumerist market.
Human settlements across the globe have shown that we can manage with 4 or 40 degree Celsius temperature with minor adjustments in food and clothing, two major means of adapting ourselves to the changing weather. Different civilisations have discovered many other means, including shifting working hours; summer and winter indoor spaces; orientation-based wall thickness; and varied window detailing.
In many ways, human adaptation to weather was akin to those of slumbering animals or leave shedding plants, learning from the animal and survival instincts we all possess. Given this natural phenomenon, it is more important that we adapt to room temperatures and not install air conditioners to force the room to adapt to us.
If millions of Indians are living without AC, it should be possible for the minority few of us also to live so. If we deny this possibility, we get into a trap where the combination of physiological and mental states will ensure we justify the AC. Even if an ecologically aware mind denies it, the body will demand it. The reverse where the mind demanding it even if body could adjust is also true.
The real challenge of summer is not to cool our body with cold rooms and even colder drinks, which only increase the variation between body and atmospheric temperatures. We need to reduce this variation by consuming warmer drinks and keeping the indoor air humid. After all, we cannot air condition the whole city, but can condition the body to adapt.
In case AC is already a habit, we can try modulating indoor humidity, air velocity and room temperatures to minimise damage to environment. Instead of 22 degree of dry cold, 28 degree with increased humidity may be better. If outside temperature is around 40 degrees, indoors at 28-35 could still be fine. Individually, we cannot switch off hotel or office AC, but can avoid the coldest parts, totally avoiding AC elsewhere.
The perils of modern lifestyle are yet to dawn on us. The few who talk about climate in kitty parties are yet to walk the talk. One simple way of doing the walk is to minimise or live without air conditioners.
