Our planet is being subjected to a large number of extreme weather events. Now in summer, with the increase in temperatures and the decrease in rainfall, the dry seasons begin. Droughts are very harmful both for humans and for species of flora and fauna. Water is synonymous with life, and increasingly frequent, intense, and long-lasting droughts are destroying the balance of many ecosystems. These droughts are exacerbated by the effects of climate change. global climate change.
Increased droughts and temperatures
In recent years, historical highs have been recorded for various global parameters due to extreme weather events. Extreme temperatures, extreme rainfall levels, extreme wind speeds, etc. For example, This ancient April was the hottest in 137 years. The National Oceanic and Atmospheric Administration (NOAA) of the United States indicates that in April 2016 and 2017 the two largest positive anomalies of global ocean temperature have been registered since 1880. This has its explanation and is based on the increase in concentration of greenhouse gases in the atmosphere. On June 14, 2017, an atmospheric CO2 concentration of 409,58 parts per million (ppm) was recorded, a measure that confirms the continuity of the increase in greenhouse gases and that constitutes the highest peak of atmospheric CO2 detected on Earth for 800.000 years.
It must be assumed that the importance of greenhouse gas emissions due to human action and their impact on the climate is undeniable. There are studies that claim that man-made global warming atmospheric dynamics are changing. This causes the frequency and intensity of extreme weather events to increase. Many heat waves and floods experienced in the Northern Hemisphere are caused by greenhouse gas emissions that trigger climate change and global warming. For more information on this, see the article on the new heat wave affecting several regions.
The relationship between high temperatures and extreme weather is evident. According to many studies, temperature records not seen in decades, adding pressure to already fragile ecosystems. In addition, this increase in temperature also impacts the fauna in different ways.
Predict the future
To be able to predict well what will happen in the future, measurements and observations that are as reliable as possible are needed. It is necessary to know, according to the variables that change over time, how our planet is going to affect us directly and indirectly. Analyzing the past is very useful for predicting the future. By studying past climate changes, we can generate models that help predict the future. We can accurately determine how certain meteorological variables may change due to increased greenhouse gas concentrations. This way, we can predict how they will behave today and what to do to avoid the greatest possible damage.
It is up to scientists to study the causes, consequences, and evolution of climate throughout Earth's history and into the future. Politicians, for their part, should listen to specialists and base their decisions on scientific data. But in addition to taking into account the evidence that scientists show, it is important, for the good of all, that what they say is correctly understood. However, the most obvious American policy is turning against the fight to avoid climate change with Donald Trump's withdrawal from the Paris Agreement. To better understand the impact of the sea temperature in climate change, it is essential to consider these factors.
The study of changes in weather patterns It is based on the collection of data from different periods, which helps predict future droughts and floods. In this sense, the situation of the drought in Spain raises serious concerns.
Efforts to stop climate change are not enough
It's sad to see how the effects of climate change are becoming more evident every day, with catastrophes claiming thousands of lives each year. Yet, efforts to halt global warming are not enough. Even if all countries in the world fully complied with the Paris Agreement, average temperatures would rise above the 2 degrees that the scientific community establishes as a limit. The challenges posed by climate change are important and urgent. The solutions are complex, among other things, because they require multinational agreements, immediate and long-term action, and acting generously. Faced with a problem of such magnitude and of global significance, the participation of all is required, in particular of those who have more capabilities and can contribute more.
The changes we are already seeing in the environment indicate that many regions of the world are acutely suffering from dwindling water resources due to prolonged droughts. It is crucial to monitor the impact of heat waves in these vulnerable ecosystems.
