Climate change affects not only the environment, but also the activities of humanity as a whole. Due to this, some jobs and positions may be cancelled and replaced by new vacancies, but the biggest challenge is avoiding unemployment and building a stable economy. An increase in temperature by only 2 degrees can lead to unpredictable consequences, which humanity must take into account.
The ecological situation affects every person, so everyone must monitor the environment’s impacts on their behaviour. This is the only way to avoid serious consequences. The natural climate and work disasters always go hand in hand. It is similar to a migraine when the air temperature changes and magnetic storms begin. A few months ago you got a great job, but after a while you realized that literally everything annoys you in this new place. So, how to quit a job when you just started? First, don’t panic. Neither stress nor climate should influence your decision. It is necessary to study everything thoroughly, up to weather conditions and ecology, because ecology is not only unfavourable conditions for life artificially created by mankind, but also thinking, clarity of mind.
There are Several Reasons for Environmental and Climate Footprint
- Sharp demographic shift
It’s associated with urban growth and has widespread implications. One of the most sensitive consequences for residents is the deterioration of air quality. Cities in poor developing countries do not have the practice of capturing emissions. Until recently, changes in air quality due to increasing urban densities have not been quantified in detail, and their impact on regional climate and global warming is still not systematically documented.
- Impact of cities on weather
Firstly, urban characteristics such as morphology and heat generation will continue to influence local temperature, air circulation, precipitation, and the frequency and intensity of thunderstorms.
Secondly, changing chemical emissions and feedbacks from atmospheric pollutants will contribute to climate change both locally and at a wider spatial scale. Cities have many features that can affect atmospheric circulation, turbulence and microclimate. These features can alter the transport, dispersal and deposition of air pollutants both in cities and downstream (acid rain is a form of this). The following main examples can be cited:
- The placement of buildings and other obstacles (or more generally all terrain irregularities) affects the turbulence;
- The widespread use of waterproof and airtight materials and the frequent reduction of vegetation cover affect the hydrometeorological regime and the deposition of pollutants;
- Anthropogenic heat release from human activities (such as transportation and heating and cooling of buildings) affects temperature conditions;
- The release of pollutants (including aerosols) affects radiation transport, cloud formation and precipitation;
- The geometry of streets (“street canyons”) affects the circulation and heat transfer between different surfaces (such as roads and walls).
The end result is powerful heat islands – areas where temperatures are higher – which can result in temperatures several degrees higher in cities than in nearby rural areas. This temperature difference can cause disruption of air circulation at the regional level. Wind regimes can be disrupted to an even greater extent due to the increasing number of high-rise buildings. Such disturbances can lead to changes in rainfall levels, air pollution and the frequency of thunderstorms.
- Air quality in megacities
Some international studies have recently been initiated to address these issues. Research aims to assess the impact of megacities and large hotspots of air pollution on air quality at local, regional and global levels, quantify the feedback mechanisms between megalopolis air quality, local and regional climate and global climate change, and develop improved tools to predict air pollution levels in metropolitan areas. While important advances have been made, new interdisciplinary research is needed to better understand the relationships between emissions, air quality, and regional and global climate.
Pollutants typically enter the atmosphere from urban transport, energy production and other industrial sectors and have an impact on the environment that is detrimental to its health. However, this pollution is not confined to the boundaries of the megacities themselves, but can be transported over long distances and contribute to the overall background pollution on a hemispheric scale.
- Future strategy
The needs and requirements of each city should be based on information obtained through a holistic approach to identifying impacts and hazards so that specific vulnerabilities can be mapped and the services that will most benefit can be identified. The problems of coastal cities are different from those of inland cities, just as the needs of cities in the tropics are different from those of cities that are exposed to severe winter weather.
Urban services rely heavily on high-resolution environmental prediction models that capture real-world city-specific processes, boundary conditions, energy flows and physical properties. New city-centred observing systems are needed to provide inputs to these models and provide high quality forecasts for new services. The use of new, targeted, needs-driven communication tools with users is necessary to ensure that services, advice and warnings lead to appropriate action and feedback to improve service. New skills and capabilities are required to make the best use of new technologies to prepare and deliver new services in a complex and constantly evolving urban environment.
So are you. Man and nature are closely related. If you listen to yourself and your needs, based on what is happening in the world around you and in your own inner world, you can even control the weather!
