Climate Change and Human Evolution
Author's preface: This was originally published in 2017 but still rings true today. The debate I read a brief exchange about the climate change debate this morning and it got me thinking all day about the topic. One of the questions that I kept returning to in my mind related to how humans and every other species on the planet will or will not adapt to the new environmental conditions that climate change will quite probably impose across much of the globe. For other species the answer is fairly obvious I think, they will either adapt or they will perish. As has been the case throughout all of earth’s history evolution through natural selection requires that those with the traits that are best adapted to reproduce will do so and so pass them on, especially when pressed by changes in the environment. Some have argued that the changes we are seeing or will soon see as a result of climate change are occurring too rapidly for many species to adapt. In essence that evolution cannot keep up with the pace of change. Mutations simply cannot occur frequently enough to supply a wide enough variety of phenotypes of different varieties to allow for at least one that can survive the new conditions any given species may find itself in. As usual rapid changes are the hardest for the longest lived (excluding microorganisms), and slowest reproducing creatures to deal with and they face the greatest threat of massive population decrease or even extinction. I happen to think that adaptation can happen much faster than is typically believed but I am not naive enough to think that even a greatly accelerated adaptation or mutation process will be enough to save all or even most animal species from the threat of habitat loss or change brought about by global warming.

Maintaining AQI in Major Cities & Basics of Air Purification
The air surrounds every element of our society, with a proper composition it is around us all the time. However, the air is not always the same, the composition at one place differs from the other. Similarly, it can be different at times on a single day for a single location. Seems pretty tough to understand, but it is just a part of how external particles can affect the basic structure of air. For an instance, the AQI - known as the Air Quality Index defines the daily air quality of a location with respect to time.

Global Warming
The global climate is changing rapidly compared to pre-industrial times, and there is several evidence that these changes are having an impact on organisms, ecosystems and human systems (high confidence). The increase in global mean surface temperature (GMST) compared to 1850 and 1900, 0, reached between 2006 and 2015 ; the increase in frequency and magnitude of these impacts is very encouraging ; this indicates that a rise in GMST of 1.5 ° C or more will have an impact on natural or human systems, regardless of whether this increase is 1.6 ° C to 2 ° C.

MONSTER HEATWAVE IN CANADA.
Hello guys, Normally Canada is considered as one of the coldest country in the world, as we know that temperature of -20°and-30°Celsius is not a great thing in Canada. But in the last few days there is a severe heatwave which caused the temperature to go beyond 49.6°C i.e., almost 50°C, you can expect this temperature in UAE or any of the middle east countries, but now it is also seen in Canada. How did these happen? Let’s try to know in today’s Article.

What Is The Lifespan Of Our Planet
If the brightness of our star increases by 10%, the earth will no longer be in the habitable zone surrounding our star. When the Sun stops burning hydrogen in its core, Mars will be outside our habitable zone and we will be too hot to keep water on our surface. Like all things in the universe, our planet Earth will fizzle out.

World Environment Day 2021
June 5 are attending to be celebrated as World surroundings Day around the globe on Saturday. it is the largest awareness campaign, that launched by the globe organization inside the first 70s. it's that time of the year once civil societies, environmentalists, faculty students and world leaders take a flash to mirror upon the impact of act on Mother Earth. With the climate crisis making some irreversible changes to our lives as we have a tendency to all are aware of it, World surroundings Day is to boot the time to possess religion in distinctive, potential solutions which will facilitate in partitioning issues like deforestation, plastic pollution etc.

‘Mummy, how long is it until we get there?’ ‘Not too long now,’ Soleil said softly, turning around to look at her young daughter sat harnessed in the rear seat of the car. She could see that Lana was tired, and reached back to gently brush away hair covering her daughter’s small, plump face.

Kin
Her strength was gone, her abdomen ached. It took everything she had to escape, but she knew if she could just pull herself over to the shattered street she could breathe, if only for a moment. With one last effort, she hoisted herself over the ridge, the weight of her exhaustion throwing her on her back. She laid there slumped on the cold wet ridge, the sun beginning to retreat behind the jagged horizon. The rain pitter-pattered across her body, rinsing the once stark white sneakers her mom gifted for her birthday, now soiled and unrecognizable. Her breath was heavy, now beginning to slow, not from relief but from necessity. It was finally quiet on the road except for the rain hitting the bent street lamp above her in rapid succession. Thunder continued to roar above, but the frustrated bellows of her pursuers had stopped. She could no longer hear them. As she realized this, she took one moment for herself, closed her eyes and breathed deeply. As she caught her breath, old memories began firing in her mind, like the fireworks from the 4th of July. She laughed softly embracing this simple moment. With her eyes still closed, she analyzed her situation. "I got it, I got it…" She continued breathing heavily as she patted her bag feeling for the large rectangular outline. "Okay. Okay." Celebrating with a big exhale. She lied there for another minute. She opened her eyes, sat up, and almost mechanically moved her arms and legs checking to make sure everything was still working properly. "I don't think anything is broken. It's cold-- why am I sitting in this muddy water?" She asked herself. Suddenly alert, her eyes widened "They're still looking for me. I can't stay here; I have to move." She rolled over sitting on her hands and knees, and as her survival instinct kicked in she pushed out several heavy puffs of air through her nose like a determined bull going for the red cloth.
