Change Mitigation

Climate change is any substantial change in Earth’s climate that lasts for an extended period oftime. Global warming refers to climate change that causes an increase in the average temperature of thelower atmosphere. Global warming is the combined result of anthropogenic (human-caused) emissionsof greenhouse gases and changes in solar irradiance, while climate change refers to any change in thestate of the climate that can be identified by changes in the average and/or the variability of its properties(e.g., temperature, precipitation), and that persists for an extended period, typically decades or longer.Green open space is one of solution for climate change mitigation.

Change Mitigation

Paris Agreement of December 2015 was the last official initiative led by the United Nations (UN) as the driver of climate change mitigation. Climate change was hence linked with an increase in the occurrence of natural hazards. A variety of initiatives were consequently adopted under different themes such as sustainable cities, climate-friendly development and low-carbon cities. However, most of the initiatives targeted by global cities with urban areas being the focus in terms of taking action against global warming issues. This is due to the structural and environmental features of cities characterized by being populated, as such, they not only generate a large number of carbon emissions but also happens to be the biggest consumer of natural resources. In turn, they create a microclimate, which contributes to climate change. Masdar City, for example, was designed as the first fully sustainable urban area, which replaced fuel-based energy with the electric-based energy. China, as another example, introduced the Sponge Cities action, a method of urban water management to mitigate against flooding. Consequently, architects and urban planners are urged to conform to the proposals that would mitigate global warming. This paper, as a result, examines some of the models that have been internationally adopted and thereafter provide the recommendations that can be implemented in large urban areas in Turkey, primarily in Istanbul.

Change Mitigation

Global warming is expected to increase the frequency and intensity of severe water scarcity (SWS) events, which negatively affect rain-fed crops such as wheat, a key source of calories and protein for humans. Here, we develop a method to simultaneously quantify SWS over the world’s entire wheat-growing area and calculate the probabilities of multiple/sequential SWS events for baseline and future climates. Our projections show that, without climate change mitigation (representative concentration pathway 8.5), up to 60% of the current wheat-growing area will face simultaneous SWS events by the end of this century, compared to 15% today. Climate change stabilization in line with the Paris Agreement would substantially reduce the negative effects, but they would still double between 2041 and 2070 compared to current conditions. Future assessments of production shocks in food security should explicitly include the risk of severe, prolonged, and near-simultaneous droughts across key world wheat-producing areas.

Climate change caused due to our careless activities towards our nature, ecosystem, and whole earth system. We are paying and will be paying in future for our irresponsible activities in past and present. Increased concentration of Green House Gases (GHG) has caused severe global warming which will cause melting of glacier and results in sea level rise. To avoid and reduce the intensity and severity of global warming and climate change, its mitigation is essential. In this chapter we have focused on various issues related with climate change and mitigation strategies.

Global warming or Climate change refers to long-term fluctuations in temperature, precipitation, wind, and other elements of the Earth's climate system. Natural processes such as solar-irradiance variations, variations in the Earth's orbital parameters, and volcanic activity can produce variations in climate. The climate system can also be influenced by changes in the concentration of various gases in the atmosphere, which affect the Earth's absorption of radiation.

Solar Radiative Flux

Statistical analysis of the number of destructive earthquakes versus global temperature and greenhouse gases revealed very significant correlations. The motion of the North Pole, deduced from the geomagnetic polar shift data, is highly correlated with major earthquakes. This is an indication that the frequent occurrence of major earthquakes had increased earth’s obliquity and possibly induced global warming and emission of greenhouse gases. It was shown by a simple model developed here that seismic-induced oceanic force could enhance the obliquity leading to increased solar radiative flux on earth. The increase of the absorbed solar radiation due to polar tilt was also confirmed by SOLRAD model which computed a net gain of solar radiative forcing due to enhanced obliquity. SOLRAD also revealed a poleward gain of solar radiative flux which could have facilitated the observed polar amplification of global warming. Multiple regression analysis also showed that polar shift and solar irradiance played a major role in the temperature rise and CO2 increase in recent years. The analysis showed that obliquity change due to North Pole shift and total solar irradiance accounted for 63.5% and 36.4% respectively, while CO2 changes accounted for 0.1% of the observed global warming. Preliminary simulations conducted with EdGCM climate model also showed that enhanced obliquity increases the absorbed solar radiative flux, surface air and ocean temperatures, and decreases ocean ice cover. This study confirmed in several ways that earthquake-perturbed obliquity change, and not greenhouse effect, is the major mechanism governing the present global warming and climate change problem.

Efecto de la quema en caña de azúcar sobre el carbono de un Andisol. En la producción de caña de azúcar la quema previa a la cosecha es una práctica común, la cual reduce la biomasa que potencialmente se incorporaría al suelo, por ello, se asume que disminuye el carbono orgánico del suelo. Esta investigación cuantificó en Turrialba, Costa Rica, el carbono orgánico por unidad de suelo en una plantación comercial de caña de azúcar, con y sin la práctica de quema previo a su cosecha. En el 2019 se implementó un diseño irrestricto al azar y se evaluaron tres tratamientos: a) un año de renovación de la plantación y cosecha en verde sin quema (testigo, TO), b) un año de renovación (T1) y c) cuatro años de renovación con quema previo a la cosecha (T4); todos con tres repeticiones. En ellas se recolectaron muestras de suelo hasta 70 cm de profundidad. Se determinó interacción (P<0,0018) entre la profundidad y la quema en el contenido carbono orgánico, los valores disminuyeron marcadamente con la profundidad en T4 comparados a los de T0 y T1. La relación C/N del suelo se incrementó significativamente (P<0,0001) con las veces que se quema previo a la cosecha, ya que los valores fueron mayores en T4 con respecto a los determinados en T0 y T1. El nitrógeno del suelo fue mayor (P<0,0016) en T0 y T1 con respecto a T4. Se determinó correlación (P<0,0001) entre el COS y el N, así como también entre la CE y el carbono, y entre el contenido de arcilla y carbono. Es notorio el efecto detrimental provocado por la quema en el contenido de carbono orgánico del suelo.Palabras clave: Cambio climático, mitigación, gases con efecto invernadero, trópico, cultivos tropicales.
