The Current Scenario of Climate Change and Its Impact on the Planet

| Climate Changes |
Climate change refers to the long-term alteration in Earth's climate patterns, primarily caused by human activities that result in increased concentrations of greenhouse gases (GHGs) in the atmosphere. The effects of climate change have been observed in various forms such as rising temperatures, melting glaciers, ocean acidification, extreme weather events, and changes in precipitation patterns. These changes have severe consequences on the environment, human health, and the economy. In this article, we will discuss the current scenario of climate change and its impact on the planet.
The current scenario of climate change is alarming, with global temperatures rising at an unprecedented rate. According to NASA's Goddard Institute for Space Studies (GISS), the average global temperature has increased by 1.02 degrees Celsius since the late 19th century. The rise in temperature has been attributed to the increasing concentration of GHGs, primarily carbon dioxide (CO2), in the atmosphere. The concentration of CO2 in the atmosphere has increased from 280 parts per million (ppm) in the pre-industrial era to over 400 ppm currently.
effects of climate change
The effects of climate change can be seen in various forms, including rising sea levels, melting glaciers, and changes in precipitation patterns. Rising sea levels are a result of the thermal expansion of water and the melting of ice sheets and glaciers. According to the National Oceanic and Atmospheric Administration (NOAA), sea levels have risen by 8-9 inches since 1880, and the rate of sea-level rise has accelerated in recent years. The melting of glaciers and ice sheets also contributes to rising sea levels, with the Arctic ice cap shrinking by an average of 12.8% per decade since the late 1970s.
Changes
Changes in precipitation patterns have also been observed, with some regions experiencing more frequent and intense rainfall, while others experience droughts. Extreme weather events, such as hurricanes, heat waves, and wildfires, have become more frequent and severe. The economic impact of these events has been significant, with damages amounting to billions of dollars in some cases.
impact
The impact of climate change on human health has also been observed, with rising temperatures contributing to heat-related illnesses, air pollution, and the spread of infectious diseases. The World Health Organization (WHO) estimates that climate change is responsible for over 150,000 deaths per year, and the number is expected to rise in the future.
The impact of climate change on the economy has also been significant, with damages from extreme weather events, such as hurricanes and floods, costing billions of dollars. Climate change also affects agriculture, water resources, and energy production, leading to food and water shortages, and increased energy prices. The cost of mitigating the effects of climate change is also significant, with estimates ranging from $1.6 trillion to $3.8 trillion per year by 2030.

challenges
To address the challenges of climate change, global efforts have been made to reduce GHG emissions and transition to renewable energy sources. The Paris Agreement, signed in 2015, is a landmark international agreement that aims to limit global warming to well below 2 degrees Celsius above pre-industrial levels, with a goal to limit warming to 1.5 degrees Celsius. The agreement has been ratified by 189 countries, including the United States, which re-joined the agreement in 2021.
Countries have also set targets for reducing GHG emissions, with the European Union, for example, aiming to reduce emissions by at least 55% by 2030 compared to 1990 levels. The transition to renewable energy sources, such as solar and wind power, has also accelerated in recent years, with renewable energy accounting for over 80% of new electricity capacity additions in 2020.
