Temperature Elevation In The Highlands Due To Global Warming

Temperature elevation in the highlands due to global warming

It is said that the elevation of temperature in the highlands due to global warming would favor long -term agricultural production, one of the reasons indicated to sustain this statement is related to the shortening of the plant’s growth cycle, which will allow "Avoid "Topical frost of winter Andino. While this is a reasonable fact, and in fact it has been observed that in recent years quinoa production has grown in places where it was not done because of the cold extreme, but it is not taken into account, however, theWater availability in the highland region. Studies related to Andean glaciers show a rapid decline in them in recent years. Even more, since glaciers act as water reserves in the dry season, their disappearance would be catastrophic for the Andean ecosystem and possible crops that could appear as a result of an eventual temperature increase. Additionally, even if the water provision was not a problem, not all plant species are able to adapt to the high levels of ultraviolet radiation received in the Bolivian highlands.

Biomass burning reduces global warming

This is half truth. Deliberate biomass burning produces as a result a large number of carbon particles product of combustion. This smoke is volumetrically composed, to a large extent, by particles less than 1óam (although it can reach order 1 mm with very intense fires) that can be transported to large distances.

These particles in the air in the air, which in a generic way are called aerosols, interact chemical and radiatively with the atmosphere and radiation that affects it. Although qualitatively the properties of the particles produced by the burning of biomass are well understood, the effect that these and other aerosols of anthropogenic and natural origin may have on the climate is not yet clearly understood.

Some types of aerosols, such as sulfates, product of volcanic eruptions for example, have the effect of cooling the earth’s surface while others, such as black coal, rather absorb energy and reinforce the greenhouse effect. The effect on the climate of this type of suspended particles is even more complicated because there are direct effects, such as those related to the cooling or heating of the earth’s surface, or indirect, such as those related to cloud formation.

However, the burning of plant material not only produces smoke but also releases a large amount of carbon and other greenhouse gases to the atmosphere. While smoke can lead to a short term to a cooling of the atmosphere, the effect of greenhouse gases released to the atmosphere is likely to produce a net heating effect. And in reality the smoke and other particles produced by anthropogenic activity can be inhibited by reflecting solar radiation to global warming, producing a ‘positive’ effect on the current current climate. The problem is that, as efforts are made to improve the quality of the air we breathe, we leave the free atmosphere of any ‘shield’ that re-issues solar radiation to space. This can dramatically accelerate the short -term greenhouse effect.
