Global warming is expected to have far-reaching, long-lasting and, in many cases, devastating consequences for planet Earth. Global warming, the gradual heating of Earth’s surface, oceans and atmosphere, is caused by human activity, primarily the burning of fossil fuels that pump carbon dioxide (CO2), methane and other greenhouse gases into the atmosphere.
Global warming is the long-term heating of Earth’s climate system observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth’s atmosphere. The term is frequently used interchangeably with the term climate change, though the latter refers to both human- and naturally produced warming
and the effects it has on our planet. It is most commonly measured as the average increase in Earth’s global surface temperature.
Since the pre-industrial period, human activities are estimated to have increased Earth’s global average temperature by about 1 degree Celsius (1.8 degrees Fahrenheit), however, the rate of increase has more than doubled. For the last 40 years, we’ve seen the global annual temperature rise by 0.18 degrees Celsius, or 0.32 degrees Fahrenheit, per decade. Most of the current warming trend is extremely likely (greater than 95 percent probability) the result of human activity since the 1950s and is proceeding at an unprecedented rate over decades to millennia.
Despite political controversy about climate change, a major report released Sept. 27, 2013, by the Intergovernmental Panel on Climate Change (IPCC) stated that scientists are more certain than ever of the link between human activities and global warming. More than 197 international scientific organizations agree that global warming is real and has been caused by human action.
One of the most dramatic effects of global warming is the reduction in Arctic sea ice. Sea ice hit record low extents in both the fall and winter of 2015 and 2016, meaning that at the time when the ice is supposed to be at its peak, it was lagging. The melt means there is less thick sea ice that persists for multiple years. That means less heat is reflected back into the atmosphere by the shiny surface of the ice and more is absorbed by the comparatively darker ocean, creating a feedback loop that causes even more melt, “According to NASA’s Operation IceBridge.” One of the primary manifestations of climate change so far is melting of the ice in both the poles. North
America, Europe and Asia have all seen a trend toward less snow cover between 1960 and 2015, according to 2016 research published in the journal Current Climate Change Reports. According to the National Snow and Ice Data Center, there is now 10 percent less permafrost, or permanently frozen ground, in the Northern Hemisphere than there was in the early 1900s. The thawing of permafrost can cause landslides and other sudden land collapses. It can also release long-buried microbes which can create a far more worse pandemic than covid-19.

I, Amlan Jyoti, was interested towards everyone trying to help the environment from all the waste human produces and its negative impact on environment. I am very concerned and clear about your goals and objectives towards the environment and its sustainable development. I would like to know more about the environment as I only have knowledge about in theories, I would like to practically involved in this act towards the environment. As passing time all the renewable resource are depleting rapidly, an act of sustainable development is necessary. As I found about Green Ammo trying to accomplish this goal, I was interested in their act of kindness towards the nature and wanted to join together defending the mother nature.
