Global Impact Of Climate Change – 16 September 2021 (WMO) – COVID-19 has slowed the irreversible progress of climate change. There are no signs that we are going green again, as carbon dioxide emissions are quickly recovering from the temporary spike caused by the economic crisis and are far from reduction targets. Concentrations of greenhouse gases in the atmosphere continue to reach record levels, threatening the planet with a dangerous warming future, according to a new US interagency report on Science 2021.
Global warming is causing extreme weather events worldwide, with increasing impacts on economies and societies. Billions of man-hours are wasted due to heat alone. The average global temperature over the past five years has been the highest on record. The report says there is a growing likelihood that temperatures will temporarily rise above 1.5 degrees Celsius above pre-industrial levels over the next five years.
Global Impact Of Climate Change
The scale of recent changes in the climate system as a whole is unprecedented over many centuries and many thousands of years. Even with significant measures to limit greenhouse gas emissions, sea levels will continue to rise, according to the report, threatening low-lying islands and coastal communities around the world.
We Must Prioritise Climate Change As We Emerge From Covid 19
“This is an important year for climate action. This report by the United Nations and international scientific partners provides a comprehensive assessment of the latest developments in climate science. The result is a sobering assessment that we How far are you?
“We are still far behind schedule to meet the goals of the Paris Agreement. Fossil fuel emissions have fallen this year, greenhouse gas concentrations have continued to rise, and extreme human-caused weather is affecting health, life on every continent. and affected livelihoods. Without immediate, rapid and significant reductions in greenhouse gas emissions, it will be impossible to limit warming to 1.5 degrees C, which will have devastating consequences for people and the planet we live on. We depend on it,” he said.
Guterres also delivered a video message on the release of the report at a press conference by WMO Secretary-General Prof. Petri Talas
The United Nations 2021 report on science, the third in a series, was produced by the World Meteorological Organization (WMO), the United Nations Environment Program (UNEP), the World Health Organization (WHO), and the International Conference on Climate Change. The intergovernmental panel is coordinated with participation. . (IPCC), Global Carbon Project (GCP), World Climate Research Program (WCRP) and Met Office (UK). It presents the latest science and findings related to climate change to inform international policy and action. It comes with a historical map.
What Is Climate Change? (definition, Causes, And Effects)
“During the pandemic, we heard that we need to rebuild better to keep humanity moving forward and prevent the worst impacts of climate change on society and the economy. This report shows we are headed in the right direction in 2021.” You don’t go,” said Professor Talas.
“This report is ready. Time is running out. For the 2021 United Nations climate conference in Glasgow, known as COP26, to be a milestone, we need all countries to achieve net zero emissions by 2050. Commit to, supported by long-term plans, Guterres said, strategies and national contributions that together will reduce global emissions by 45 percent by 2030 compared to 2010 levels.
“We need a breakthrough to protect people and their lives, with at least half of all climate finance going towards building resilience and adapting to people. And we need more solidarity, including Including full implementation of long-term climate finance commitments to help developing countries take action on climate change. If we are to achieve a safer, more stable and prosperous future for all, there is no alternative. ” The effects of man-made global warming are already happening, irreversible for people living today, and will get worse as people add more greenhouse gases to the atmosphere.

Climate Endgame: Exploring Catastrophic Climate Change Scenarios
Global changes are not the problem of the future. Changes in soil caused by human emissions of warming greenhouse gases already have far-reaching consequences for the environment: glaciers and ice sheets are shrinking, river and lake ice are breaking up earlier, and the geographic distribution of plants and animals. The range is growing. Transplant, and plants and trees bloom quickly.
Effects that scientists have long predicted as a result of global change are now occurring, such as melting sea ice, rapid sea level rise, and longer, more intense heat waves.
“The magnitude and speed of change and associated risks depend largely on short-term mitigation and adaptation measures, and projected negative impacts and associated losses and damages increase with each increase in global warming.” – Intergovernmental Group for Change
Some changes (such as droughts, forest fires and heavy rains) are happening faster than scientists predict. In fact, according to the Intergovernmental Panel on Change (IPCC), a United Nations agency set up to assess scientific research on change, modern humans have never seen more visible changes in our global environment than before. , and some of these changes will be irreversible in the world. near future Hundreds and thousands of years.
Climate Change Amplifies Instability In Africa
Scientists are confident that global warming will continue for several decades, mainly due to greenhouse gases produced by human activities.
Thus, the Earth’s average temperature rose by about 2 degrees Fahrenheit during the 20th century. what is the problem?
The IPCC’s Sixth Assessment Report, due out in 2021, found that human emissions of greenhouse gases have already risen by nearly 2 degrees Fahrenheit (1.1 degrees Celsius) since 1850-1900.
Average global temperatures are expected to rise by 1.5 degrees C (about 3 degrees F) in the coming decades. These changes will affect all parts of the Earth.
Climate Change & Health
“Global warming” refers to the long-term warming of the planet. “Change” includes global warming, but refers to a wide range of changes to our planet, including rising sea levels; shrinking mountain glaciers; Rapid melting of ice in Greenland, Antarctica and the Arctic, as well as changes in the flowering time of flowers/plants.
The magnitude of the consequences caused by the changes will depend on the course of future human activity. The increase in greenhouse gases will cause more severe disasters and significant damage across our planet. However, these future impacts depend on the total amount of carbon dioxide we emit. So if we can reduce emissions, we can avoid some of the worst consequences.
“The science is clear: change is a threat to human well-being and the health of the planet. Any further delay in concerted global action will miss a short, rapidly closing window to secure a viable future.” Intergovernmental Panel on Climate Change
Change brings all kinds of problems to every region of the country. Some current and future impacts are summarized below. These findings are derived from the third
The Global Impact Of Climate Change
People have already made big changes, and we are starting to make more changes. But if we stopped emitting greenhouse gases today, global warming would begin to stabilize within a few years. Then the temperature will drop, but remain very high for many, many centuries.

Scientists using space-based radar have found that New York City’s land is sinking at different rates due to human and natural factors. A few places are going up.
The annual minimum (lowest) extent of Arctic sea ice was the sixth lowest on record this year, while Antarctic sea ice reached its lowest extent on record. Both of these indicators continue to experience long-term declines due to human-caused global warming.
The International Surface Water and Ocean Topography Mission has the ability to measure El Niño-like ocean features closer to the coast than previous space missions.
