How does air conditioning affect global warming

What are the consequences of climate change and global warming?

It is scientifically not possible to ascribe individual weather events to current climate change, but it can be statistically proven that global warming increases the probability of extreme weather events.

The direct consequences of man-made climate change include:

  • increasing maximum temperatures
  • rising minimum temperatures
  • rising sea level
  • higher sea temperatures
  • increasing heavy precipitation (heavy rain and hail)
  • Glacier retreat and retreat
  • thawing permafrost

The indirect consequences of climate change that directly affect us humans and our environment include:

  • Increase in hunger and water crises, especially in developing countries
  • Health risks from rising air temperatures and heat waves
  • economic consequences for the elimination of the consequential damage to the climate
  • further spread of pests and pathogens
  • Loss of biodiversity due to limited adaptability and speed of flora and fauna
  • Ocean acidification due to increased HCO3 concentrations in the water as a result of increased CO₂ concentrations
  • Adjustment need in all areas (e.g. agriculture, forestry, energy industry, infrastructure, tourism, etc.)

Since the global climate is a highly networked system that is influenced by many different factors, the consequences usually result in positive or negative feedback effects. This is understood to mean developments that have a self-reinforcing effect when certain conditions occur.

A common example is ice albedo feedback, which relates to the melting of the polar ice caps. Extensive ice surfaces have a cooling effect on the global climate, as a high proportion of radiation is reflected. As a result of the global increase in the average temperature, however, these ice surfaces begin to melt, the ice surface shrinks and the radiation emitted is reduced. At the same time, the land or ocean areas, which have a significantly lower albedo, reflect less radiation and thus intensify the actual cause of the glacier melt.
In addition, scientists can calculate so-called tipping points of individual subsystems of the global climate. The higher the global temperature rise, the more the climate system is affected, so that at a certain point, despite great efforts, a reversal process is no longer possible. However, where exactly these tipping points are to be found is currently still unclear and can only be calculated with great uncertainty. Such tipping points are expected for the melting of the polar ice caps or the stability of important ocean currents.
