ANALYSIS OF THE PROBLEM OF CLIMATE CHANGE

Climate change is changes in temperatures and weather patterns. These changes can be natural, for example the variation of the solar cycle.

But it is also due to human activities such as the burning of fossil fuels such as coal, oil or gas, this burning of fuels generates greenhouse gas emissions, these gases trap heat from the sun and increase temperatures. This leads to global warming.

Change will continue to occur during this century and beyond.

Climate change is projected to continue throughout this century and beyond. The magnitude of climate change beyond the coming decades will exceed how much heat-trapping gases are emitted on a global scale and how sensitive the Earth's climate is to such emissions.

temperatures will continue to rise

Because human-induced warming is superimposed on a naturally variable climate, the temperature increase has not been, and will not be, uniform or even across the country or over time.

Frost-free season (and growing season) will be prolonged

The length of the frost-free season (and the corresponding growing season) has increased across the country since the 1980s. The most significant increases occurred in the western United States and affected ecosystems and agriculture. The growing season is predicted to continue to drag on across the United States.

In a future in which emissions of heat-trapping gases may increase, an increase of a month or more in frost-free and growing periods is projected for most of the United States by the end of the century. There will be slightly smaller increases in the northern Great Plains. The largest increases in the frost-free season (greater than eight weeks) are projected for the western United States, particularly in high elevation and coastal areas. Increases will be lower with decreases if greenhouse gas emissions will be reduced.

It multiplies extreme climatic phenomena such as floods and droughts, heat waves and cold waves, aggravates desertification and erosion processes and entails a generalized loss of biodiversity.

The effects of climate change will affect our health through heat waves, droughts, storms, and sea level rise, as well as respiratory diseases, food insecurity, water insecurity, and malnutrition.

There are direct effects of climate change: Injuries, illnesses and deaths.

In addition, it will increase the risk of diseases transmitted by contaminated water, increased growth of microbes, vector-borne diseases, increased risk of malnutrition due to the drop in food production, increased stress and risk of mental illness.

Melting ice in the Antarctic and Greenland will also contribute to sea level rise. The sea level could rise between 25 and 50 cm by the year 2100.

Changes in climate will affect many crops grown around the world. Like wheat and rice, which grow well in hot temperatures, while plants like corn and sugarcane thrive in cooler climates.

Changes in rainfall patterns will also affect the growth of plants and crops. This can lead to some countries not having enough food. 

In many regions, like Africa, there is not enough water for people. Changes in climate will change weather patterns and bring more rain to some countries, but others will have less rain, generally dry areas will become drier and wet areas could become wetter.

As climate change occurs, our daily weather and normal temperatures will change, the homes of plants and animals will be affected all over the world.

The number of extreme weather, climate and water events is increasing and will become more frequent and severe in many parts of the world as a result of climate change. That means more heat waves, droughts and wildfires like the ones we have recently seen in Europe and North America.

Changes in precipitation patterns.

Average precipitation in the United States has been on the rise since 1900, but some areas have seen increases greater than the national average, and others have seen decreases. For this century, more precipitation is expected for the winter and spring in the northern United States and less precipitation for the Southwest. Projections for future climate in the United States suggest that the recent trend toward an increase in heavy precipitation events will continue. This trend is predicted to occur even in those regions where precipitation totals are expected to decrease, such as the Southwest.

Climate changes will affect everyone, but some populations will be most at risk. Countries whose coastal regions have large populations, such as Egypt and China, may have to move entire populations inland to avoid flooding. The effect on people will depend on how well we can adapt to the changes and how much we can do to reduce climate change in the world. There is still time to analyze the situation as a society and we will not let this go any further.

It is necessary to understand the technological and regulatory changes that will have to be made in the coming years, since depending on the evolution of the changes in the economic sectors, institutions and Spanish society in general, we will be more or we will not be able to adapt those changes and their effects will affect us differently.

With more good actions towards our planet, climate change will not be able to affect us in a significant way, on the contrary, a solution would be with the help of everyone as people to become aware of what will happen in the coming years, for this reason we must create habits that will avoid May this change continue to advance as the years go by.

The human-caused effects of global warming are happening now, are irreversible in the time scale of people living today, and will worsen for decades to come.
