Human action is causing an increase in global temperature. For that reason, the greenhouse effect, far from being our great ally as was the case in the past, is now a risk to our survival. The flooding of coastal cities, the desertification of fertile areas, the melting of glacial masses and the proliferation of devastating hurricanes are just some of the main consequences.
Global warming is having a profound impact on the processes of soil degradation and is contributing to the desertification of the most arid areas on the planet. The increase in the global temperature of the planet produces a rise in the level of the sea, which will cause the disappearance of islands and coastal cities. The greenhouse effect is a natural phenomenon and is beneficial for us. Certain gases in the atmosphere retain part of the thermal radiation emitted by the Earth's surface after being heated by the sun, this maintains the planet's temperature at a level suitable for the development of life.
Human action, however, has increased the presence of these gases in the atmosphere — mainly, carbon dioxide and methane —, causing them to retain more heat and to increase the temperature on the planet.
This is what we know as global warming. The increase in the average temperature on Earth is changing living conditions on the planet. Let's find out about the main consequences of this phenomenon:. Thawing will produce a global rise in sea level and the release of more methane, among other consequences. The decrease in agricultural and livestock production will bring about the food shortage.
Reducing emissions of the so-called greenhouse gases, such as CO 2 or CH 4 is not the only solution to curb the greenhouse effect. International organisations also agree on the following recommendations:. Climate action is synonymous with any policy, measure or programme that works to reduce greenhouse gases, builds resilience to climate change or supports and finances those objectives. The Paris Agreement was the first major international agreement towards those ends.

Numerous gases that are part of the atmosphere absorb the Earth's infra-red radiation, producing an increase in the temperature of the surface of our planet and the atmospheric layer that surrounds it. Radiation escaping into space. Evolution of CO 2.
CO 2 is the gas that contributes the most to the greenhouse effect. We present the history of emissions in the world during the last decade.
Let's find out about the main consequences of this phenomenon: Thawing of glacial masses Glaciers retreat also has its own consequences: reduced albedo — the percentage of solar radiation that the earth's surface reflects or returns to the atmosphere —, a global rise in sea level and the release of large methane columns are only some of them, however, they are all dramatic for the planet.
Flooding of islands and coastal cities According to Intergovernmental Panel on Climate Change IPCC, , during the period the global average sea level rose 19 centimetres. It is estimated that by the sea level will be between 15 and 90 centimetres higher than it is now and will threaten 92 million people.
Hurricanes will be more devastating The intensification of the greenhouse effect does not cause these extreme climatic events, but it does increase there intensity.
Hurricanes formation are connected with sea temperature — they only form over waters that have a temperature of at least Migration of species Many animal species will be forced to migrate in order to survive the changes in the main climatic patterns altered by the progressive increase in temperatures.
Human beings will also have to move: according to the World Bank, by the number of people forced to flee their homes due to extreme droughts or violent floods could reach million. Desertification of fertile areas Global warming is having a profound impact on the processes of soil degradation and is contributing to the desertification of areas on the planet, a phenomenon that destroys all the biological potential of affected regions, turning them into barren and unproductive land.
Impact on agriculture and livestock Global warming has already altered the length of the growing season in large parts of the planet. Similarly, changes in temperatures and seasons are influencing the proliferation of insects, invasive weeds and diseases that can affect crops.
The same is happening with livestock: climatic changes are directly affecting important species in multiple ways: reproduction, metabolism, diseases, etc. The intensity of hurricanes will be greater due to the greenhouse effect. Many animal species will migrate as consequence of the high temperatures. With global warming, insects, invasive weeds and diseases will affect crops.
The spread of diseases and pandemics In addition to the problems derived directly from pollution, the World Health Organization WHO states that global warming will cause infectious diseases such as malaria, cholera or dengue to spread to many more areas of the planet. On the other hand, extreme heat will increase and aggravate cardiovascular and respiratory problems.
Global warming will spread infectious diseases across the planet. International organisations also agree on the following recommendations: Use renewable energy.
Global Warming 101
Global warming , the phenomenon of increasing average air temperatures near the surface of Earth over the past one to two centuries. Increases in greenhouse gases —i. Continued global warming is expected to impact everything from energy use to water availability to crop productivity throughout the world. Poor countries and communities with limited abilities to adapt to these changes are expected to suffer disproportionately. Global warming is already being associated with increases in the incidence of severe and extreme weather, heavy flooding , and wildfires —phenomena that threaten homes, dams, transportation networks, and other facets of human infrastructure.
Climate change is a global challenge that has no borders and to combat it requires coordinated work by all countries. In these pages, we tackle the subject from an objective, scientific viewpoint , discussing the causes and consequences of climate change and how it should be tackled. One of the MOST amazing video's and explinations on climate change. The main cause of climate change is global warming, which has many negative consequences on physical, biological and human systems, as well as other effects. Carbon dioxide, Methane, Nitrogen oxide, HCFCs : caused mainly by the burning of fossil fuels in electricity generation, transport, heating, industry and construction. Also caused by livestock, agriculture mainly rice farming , wastewater treatment and landfills among others. The forests and rainforests are disappearing at breakneck speed.

What is climate change and how does it affect us?
What is global warming? What causes global warming? What is climate change? Is it different from global warming?
Global warming is likely to be the greatest threat of the 21st century. Find out its causes and effects, but most importantly the solutions to prevent climate change. Climate experts are formal: the Earth is warming up at a steady pace.
The evidence is clear: the main cause of climate change is burning fossil fuels such as oil, gas, and coal. When burnt, fossil fuels release carbon dioxide into the air, causing the planet to heat up. The climate on Earth has been changing since it formed 4. Until recently, natural factors have been the cause of these changes. Natural influences on the climate include volcanic eruptions, changes in the orbit of the Earth, and shifts in the Earth's crust known as plate tectonics.

Greenhouse gases and the greenhouse effect
The potential future effects of global climate change include more frequent wildfires, longer periods of drought in some regions and an increase in the number, duration and intensity of tropical storms. Global climate change has already had observable effects on the environment. Glaciers have shrunk, ice on rivers and lakes is breaking up earlier, plant and animal ranges have shifted and trees are flowering sooner. Effects that scientists had predicted in the past would result from global climate change are now occurring: loss of sea ice, accelerated sea level rise and longer, more intense heat waves. Scientists have high confidence that global temperatures will continue to rise for decades to come, largely due to greenhouse gases produced by human activities. According to the IPCC, the extent of climate change effects on individual regions will vary over time and with the ability of different societal and environmental systems to mitigate or adapt to change. The IPCC predicts that increases in global mean temperature of less than 1.
