climate change

Climate change is a broad range of global phenomena created predominantly by burning fossil fuels, which add heat-trapping gases to Earth’s atmosphere. These phenomena include the increased temperature trends described by global warming, but also encompass changes such as sea-level rise; ice mass loss in Greenland, Antarctica, the Arctic and mountain glaciers worldwide; shifts in flower/plant blooming; and extreme weather events.”
When we talk about climate change, we are often talking about the increase in temperatures linked to industrial activities and in particular the greenhouse effect. Therefore, we sometimes speak of global warming, which is said to be “of anthropogenic origin”. Ultimately, the causes of global warming (at least at its current rate) are not natural but driven by the human economy and industries.

Many scientists are studying this phenomenon and trying to understand how activities of human societies are responsible for this heating. These scientists are grouped together in the IPCC (International Group of Experts on Climate), and they regularly publish reports studying the evolution of climate change, such as the one published in late 2018.
The Consequences Of Climate Change On The Planet’s Ecosystems
An increase in temperature due to global warming it’s not only about a heat increase that can be felt by humans or glacial ice melting – it has the potential to affect the planet’s entire ecosystem. As we have been watching in many different countries, from the US (California) to India or South Africa, the weather is getting disruptive. Extreme weather events are more regular and their patterns are changing  – they’re more intensive, aggressive, and with more energy. This means more storms, floods, cyclones, and droughts will take place over the next years.


 
At the same time, the regulating capacity of oceans is also being affected by an increase in temperatures. If global temperatures increase dramatically, ocean levels will not only increase – they will also be facing the ecological challenges of oceanic acidification and deoxygenation. At the same time, forest areas (e.g. Amazon rainforest), fragile ecosystems (e.g. coral reefs) and biodiversity (e.g. corals, insects and mammals) are also under threat.
Climate Change: Myth Or Reality?
Like many social and scientific problems, climate change has been controversial from the start. Some scientists and critics have questioned climate change. They are called climate-skeptics. Several arguments are invoked, for example:

“Climate Change Does Not Exist, It’s A Lie”
This argument, often used by skeptics, would make climate change a lie, invented by states, or world elites and the media. No evidence or explanation has been provided to support this argument.

“Climate Change Is Natural, It Does Not Matter”
This argument is often put forward by climate-skeptical scientists to question the media attention that climate change enjoys. Their idea is that climate change is a natural phenomenon, normal and cyclical, and there is no need to worry about it.
However, the work of Keeling or Revelle, and then the work of the IPCC and hundreds of newer independent works, have proved that this argument is false, and that climate change is indeed a phenomenon of human origin (as the temperatures have been rising at abnormal rates since the industrial revolution) and that it is dangerous for the world’s ecosystems and societies.
The Scientific Consensus On Climate Change

In the end, the overwhelming majority of global scientists in all relevant fields agree on the causes of climate change and most of its consequences on ecosystems and society. Scientifically speaking, there is no doubt about the existence of global warming and climate change. It is now time to find out what actions will be taken at the political and social spheres to make our world more resilient and fight climate change.

TIME TO TALK ABOUT RAPE

Time to talk about rape If men remember that women are their mothers, daughters, and wives they may change their laws The global statistics on sexual assault against women are shocking. At least one in every five women experiences rape or attempted rape during her lifetime. The recently published report from the United Nations Population Fund on the  State of the World Population 2000  is the latest of many official reports that have documented the size of the problem.Yet despite clear documentation and the fact that much attention has been paid to the issue of sexual violence against women at international level, the problem is getting worse. The UN report and other data make it clear that the incidence of rape and other forms of sexual violence is increasing worldwide.Yet even official figures underestimate the scale of the problem because the proportion of rapes reported to the authorities varies from 16% in the United States to 3% in South Africa (where ev...

The challenges of remote education

  WHAT ARE THE CHALLENGES IN REMOTE LEARNING?                                             At the outbreak of the pandemic, schools encountered numerous technical difficulties in setting up online teaching pathways, which impacted the learning outcomes of students and particularly  disadvantaged students .  The pandemic deprived schools of an essential element for the preparation of distance learning pathways, namely time. Creating a remote learning environment  requires precise planning in terms of objectives and resources and specific practice on the part of teachers .  Now that the most acute emergency phase is passing, schools need to reflect on the shortcomings of the solutions adopted so far and on how to intervene so that students and teachers can work within effective remote learning frameworks. From this point of view, the first step to...

gender misuse

Nov  10,2021 Women-centric legislation in India and its misuse Crimes against women are common in India. They are neither safe nor protected, whether at home, in public, or at work. Given the prevalence of crimes against women, certain laws aimed specifically at women have been enacted in India to protect them. The following are a few legislations enlisted for the protection of women’s rights in India: 1.  Protection of Women from Domestic Violence Act, 2005:  It is a critical statute that seeks to protect Indian women from various types of domestic violence. It protects women who are in a relationship and are constantly subjected to physical, mental, sexual, verbal, and emotional violence. 2.  The Dowry Prohibition Act, 1961:  It forbids the wanting to give or trying to take dowry from women before, during, or after their marriage. The taking or giving of dowry to the bride or bridegroom and their families at the time of marriage is prohibited by this act. 3....
