Report on climate change
The UN’s climate science panel released its highly anticipated special report on climate effects and transformation Friday. It called for urgent action to prevent the “severe and pervasive” impacts of global warming.
The United Nations has released a report about climate change developments across the globe. It’s called “Sovereign Risks in a Low Carbon World”. According to the report, climate change will cause a 1.5 degree Celsius increase in temperature by 2100. The report warns about “extreme” or “unprecedented” effects on the planet.
Today, the Intergovernmental Panel on Climate Change (IPCC), released its latest report. It predicts some “unprecedented and extreme” effects of global warming.
The summer of 2022 was marked by unprecedented extremes all over the globe, including floods and fires. This shows that climate change is already a major problem. These extremes and their connection to human-caused climate changes are just a few of the main themes in the historic UN Intergovernmental Panel on Climate Change report (IPCC) that was published Monday.
It forms part of the IPCC’s Sixth Assessment Study, the most important climate report ever released by the scientific community worldwide in years. It was composed by more than 230 top scientists across the globe.
This paper is a compilation from research from more than 14,000 sources. It is essentially a climate science dictionary. It includes a description of the latest scientific consensus on climate change, as well as a discussion about the future. This was based on historical data and advanced climate models. This update provides an overview of how Earth’s climate has changed and what our knowledge about it has been since the last report was published in 2013.
The study states that “Human influence has unmistakably heated the atmosphere, oceans and land.” The report states that many of the changes to the planet, especially in our oceans, will not be reversed for decades or millennia. Furthermore, continued warming would accelerate the occurrence of “extreme events” which are unimaginable in the observational record.
According to CBS News’ Pamela Falk, UN Secretary General Antonio Guterres stated that “the alarm bells are blaring and the data irrefutable: greenhouse gases emissions from fossil fuel burn and deforestation have strangled our planet and are putting billions in imminent danger,” according to Pamela Falk, CBS News.
The study does however, emphasize the fact that there is still plenty of time to solve the climate problem. It is important to note that each degree of warming matters and that a decrease in warming can help prevent catastrophe. In the immediate future, this will require actions like reducing methane emissions and greenhouse gases. The study shows that science suggests that humanity could continue to follow a low carbon path in the future to “deliver rapid and persistent benefits to stop human-caused climate changes.” New headquarters for the United Nations.

Professor Ed Hawkins, a University of Reading researcher, said that the main message of the report is that “climate changes are indisputably caused (primarily by fossil fuel burning and deforestation) and that they are already affecting all regions, including making extreme weather events more severe.”

He said, “To prevent global temperatures rising, urgent, rapid, and persistent reductions of greenhouse gas emissions are required.”
Unprecedented transformations
Scientists have known since the 1800s that carbon dioxide traps heat and warms the earth. Scientists and Big Oil companies realized by the 1960s that the increase in atmospheric greenhouse gases from burning fossil fuels was having negative effects on the planet.
The warning signs of climate change became more apparent, and the world community decided to come together to tackle the problem. In 1988, the World Meteorological Organization (WMO) and the United Nations Environmental Program (UNEP) created the IPCC. It is an international group of scientists and politicians that presents objective research on climate change. They also explain the potential dangers and implications to the world. The IPCC publishes full assessments every few years. Special reports are published in between.
Like the 2013 report, this year’s report leaves no doubt in doubters minds, stating unambiguously that global warming is caused by human activities. Already, “widespread and rapid changes” have occurred and are already being felt around the world.
Scientists write that large-scale indicators of climate change in the ocean, atmosphere and cryosphere (frozen areas) are rising due to human-caused global warming.
Here are some of the most important findings
The atmospheric levels of carbon dioxide (CO2) are higher than ever before in the past 2 million years. Methane has a life expectancy of at least 800,000. During the same time period, greenhouse gas growth outpaces all other natural variations.
In the past 50 years, temperatures have increased at a faster rate than any other time in the last 2,000 year. The average global surface temperature for the period 2011 to 2020 was 1.1 degrees Celsius (2 degrees Fahrenheit). This is higher than the average temperature between 1850-1899 (before humans began warming the planet). There was also more warming on land (1.6degC), than in the ocean (0.9degC). It is anticipated that the most recent decade will be the warmest since 125,000 years ago, when the last interglacial era occurred.
Rising temperatures are causing unprecedented melting rates of ice. In the last 1,000 years, Arctic sea ice has melted at a lower rate than in any previous year. Nearly all the glaciers in the world have receded since the 1950s. This is unprecedented over the past 2,000 year.
As a result, of climate gas emissions, warming and ice melting from the land, sea levels are rapidly changing. Sea level is rising at an unprecedented rate in the last 3,000 years. The global average sea level rose approximately 8 inches between 1901 and 2018. The rate of growth between 1901 and 1971 was 1.3 millimeters/year, while it rose to 3.7 milimeters/year from 2006 to 2018.
The Earth’s surplus heat is 90 percent retained in our seas. The ocean is now accumulating heat at an unprecedented rate since the last Ice Age.
The ocean becomes more acidic when carbon dioxide is dissolved in saltwater. This can lead to coral death and other threats to marine life. The study found that ocean acidification has reached unprecedented levels over the past 2 million years.
Climate change and extreme weather
According to the study, “Human-induced Climate Change is already influencing many weather and climate extremes throughout the world,” which examines severe weather.
A changing climate is causing more heat waves, severe storms and droughts, as well as increased rainfall, flooding, and other compound occurrences.
According to the study, things will only get worse. The study predicts “extreme occurrences unsurpassed in the observational records” with 1.5degC global warming. This is likely to be the case by the 2030s.
Heat waves are the most obvious link between global warming, heat waves, and other phenomena. According to the study, heat waves have become more frequent and more severe in most geographic regions since the 1950s. According to the study, recent extremes are “extremely unlikely” to occur without human influence on climate system. It also noted that marine heat waves (defined as unusually high temperatures in the oceans) have almost doubled since 1980s. The majority of these have human fingerprints.
