Climate Change.

What is climate change.

Climate change is the result of global warming, and is often defined as the change of temperature and weather patterns over time.

It has become one of the most pressing global challenges of modern times.

Whate are the causes.

Human activities such as the burning of fossil fuels in industry and transport, deforestation, and land-use changes.

  • Fossil fuel burning

Burning of fossil fuels increases the amount of carbon dioxide (CO2) in the atmosphere. As a matter of fact, it contributes to worldwide greenhouse gases emissions by 31 percent of annually.

  • Deforestation

Trees store carbon dioxide. Cutting trees down remove their storage capability. In addition, trees release their stored carbon when they are burnt.

  • Livestock

Livestock contributes to climate change by producing methane, which is 30 times more powerful than carbon dioxide as a greenhouse gas. As a matter of fact, livestock and their byproducts  alone contribute to worldwide greenhouse gases emissions by 11 percent of annually.

  • Agriculture

Planting crops many different types of greenhouse gases into the air. The nitrous oxide used for fertilizers is ten times worse and is nearly 300 times more damaging than carbon dioxide.

  • Transportation

Transportation contributes to global greenhouse gases emissions by 15% annually.

What are the effects.

  • Effects on the planet

The burning of fossil fuels increases the concentration of carbon dioxide (CO2) in the atmosphere, which is one of the gases that enhances the greenhouse effect.

In addition, frequent extreme weather events occur more frequently. They include flooding and droughts, erratic rainfall patterns, wild fires natural disasters.

  • Effects on human health

The World Health Organization (WHO) predicts that there will be approximately 250,000 additional deaths worldwide per year due to climate change between 2030 and 2050.

This  includes 38,000 additional deaths due to heat exposure in elderly people, 48,000 additional deaths due to diarrhea, 60,000 additional deaths due to malaria, and 95,000 additional deaths due to childhood under-nutrition.

The increased burning of fossil fuels, as part of greenhouse gas emissions, may also result in ozone depletion leading to greater exposure to harmful ultra-violet radiation. This may cause conditions such as skin cancer, cataracts, and blindness.

In addition, it will increase diseases,epidemics and pandemics.

Moreover, these harmful effects will also bring food insecurity, lack of water, and decreased air quality.

In addition, it will increase diseases, health related conditions, epidemics and pandemics.

Is climate change real.

Even though some people think is a hoax, one only needs to look out the windows, follow the news and look at science.

Extreme weather patterns, such as heat waves, floods, major storms, drought, are on the rise.

Moreover, melting glaciers, beach erosion, wild life endangerment, wild fires are more proof of the rapid change. Food and water shortage will also increase.

The negative effects on human health and lives are also on the rise. For instance, changes in temperature, precipitation, relative humidity, and air pollution influence viral activity and transmission in humans.

Young children and older adults appear to be particularly vulnerable to rapid fluctuations in ambient temperature. For example, an increase in the incidence in childhood pneumonia in Australia has been associated with sharp temperature drops from one day to the next.

Another example an outbreak of Hantavirus respiratory disease was linked to a local increase in the rodent population in Japan, which in turn was attributed to a two- to threefold increase in rainfall before the outbreak.

This is a real and concerning danger, especially for the future generations.

What are the solutions.

We all need to work together, locally and globally. First of all, slowing and limiting global warming would be a good start.

The United Nations’ Paris Agreement includes the aim of pursuing efforts to limit global warming to only 1.5 °C above pre-industrial levels.

But many argue that will not completely remove the risk of global temperatures being much higher or of some regional extremes reaching dangerous levels for ecosystems and societies over the coming decades.
