Climate Change: IPCC Report 2021
Hello, we’ve just released a large new climate report. If you’re expecting some bad news, then you’ll be relieved to learn that there’s none. There are no fresh bombshells in this study that we didn’t previously know about. All of this was expected. We’re already seeing the impact of climate change. And this report certainly proves what our experience & also research have told us is happening. As we’ve got thousands of pages of research compiled by hundreds of scientists. Precisely revealing to us what the earth’s climate looks like right now & what the future may hold.
And, while it isn’t very upbeat, it does represent an impressive collective effort among the 195 countries that make up the IPCC (intergovernmental panel on climate change). It also establishes a single point of reference for a thorough. That is an up-to-date understanding of the climate crisis.
So far, we’ve only seen the piece on physical science foundations. Hence following 2 sections of the study, on human repercussions and how to respond, releases in 2022.
So, What Exactly Is In This Thing?
Although we spent a week going over the vocabulary. And here are some of the highlights. They are as follows:
The Strong language
For starters, the IPCC is also using definitive language in the summary for policymakers. Thus shorter and easier is to read a summary of the report. Which importantly is approved line by line by the 195 nations. In that intergovernmental part of their moniker uses words like unequivocal a bunch like
“Human influence has unmistakably warmed the atmosphere, oceans, and land.”
“Increase in well-mixed greenhouse gas concentrations due to unequivocally human activities”.
Therefore, this is significant because the IPCC usually uses more cautious language such as medium or high confidence. This is still their principal way of expressing ambiguity, but where the science is clear. As they’re letting it be clear that climate change is a result of human activity & thus having a significant impact.
Obviously, it’s old news, but it does indicate that nation from the US to Russia to Micronesia to Libya. Since they agree on a set of facts about the climate problem. Including who created it as well as how awful it is?
Though there isn’t any new research in this paper, which is kind of the theme. Simply it’s a summary of all we know right now. Or more precisely, anything published in the research journals before January 31, 2021.
For instance, since the 1980s, each decade has been warmer than the previous. Thus resulting in a global surface temperature rise of a little more than 1 degree Celsius. As 1850 is a result of human activities such as the combustion of fossil fuels.
Next, we also understand that all of this human-caused climate change is causing havoc with the hydrological cycle. Hence altering rainfall patterns, storm paths, and even ocean salinity.
Climate Change is Everywhere
Really there is no place on the planet that is immune to these effects. Because climate change is already affecting and will continue to affect every corner of the globe. What do those modifications entail?
• Firstly, it increases high heat events caused by a decrease in permafrost, snow glaciers, ice sheets, lakes, and Arctic sea ice. Having an influence on everything from agriculture to human health.
• Secondly, tropical cyclone intensification and extratropical storms.
• Floods in rivers.
• Or Fire.
• Rainfall has increased as a result of the weather.
• Dryness has increased.
Not to mention the fact that as the population of cities grows. So does the size of the urban infrastructure. Heatwaves are also becoming more severe as well as intense rainfall & flooding are becoming more frequent in those areas. All of which means that permafrost is melting & also flooding is becoming more common.
• First of all, in Alaska, land erosion is posing a threat to these homes.
• Then this summer’s high heat in the United States’ northwest and Pakistan’s Indus Valley.
• Hurricane Harvey in 2017 was a prime example of supercharged cyclones.
• Droughts such as those in the Southwest of the United States and Madagascar are more. Likely going to increase in severity & also the frequency of course.
Moreover, these atmospheric & oceanic physical changes demonstrate how physical changes in the air systems. Affect people’s perceptions of how governments respond to these disasters. And who& where they are protected. That’s a choice, but let’s not get ahead of ourselves.
Since the most likely way/place for these impacts to occur are on a regional scale. While the global average temperature is rising, the strangeness and bumpiness of the earth are increasing. That means climate change is not being experienced in the same way everywhere.
Along with the support, the IPCC has launched a website. Where you can learn more about the projections for your area. Yet this site is for you to enjoy attractive graphs that make you cry. Plus, you can also get your hands on the raw data.
Compound Extremes- Climate Change
If global warming continues, then some compound extreme events with low probability in past. As well as current climate will be more common as there’ll be a greater probability. Since the events with increased intensities, durations, and or spatial extent sun precedented in the observational record will occur.
What is a Compound Extreme?
As a result, a compound extreme is a jargony method of describing the nightmare scenario of 2 or more risks. Generally occurring simultaneously or one after the other. It does not appear to be terrifying. For example, a heatwave in a region already suffering from drought. Or a wildfire followed by a major storm, or a brutal cold snap following a flood. Because these extremes are extremes by definition & are uncommon.
So, what’s the point? They’re essentially saying, “Well, here are these dangerous unusual events.” They’re not going to be as rare as they once were. While one extraordinary scenario can already put a strain on emergency preparedness systems, resources, and reactions. Just trying to add another can be disastrous. Although a bit of a one plus one counts way more than 2 situations. Basically in terms of our ability to prepare for and react.
Every Degree Matters
As the research report makes it quite clear. Everything beyond the projected repercussions and consequences of warming just gets worse. When the temperature crawls higher, regardless of whether temperatures climb by 1.5 or 2 degrees.
Let’s take an example, with 1.5 degrees global warming. Now intense heat episodes occur roughly 5 times as frequently as they did previously. Wherein starting at 9 times the frequency of 2 degrees. As well as 14 times the frequency of 9 degrees. Fire, climate, droughts, severe rainstorms, and floods are all examples of this.
Consequences and Aftermath
Essentially, the report is a collection of negative news in one spot. Because the links between terrible fire seasons, catastrophic flooding, terrifying cyclones are widespread. By confirming accelerated climate changes.
Physical climate consequences are not a guarantee of cataclysmic end times. But the IPCC has set it all out for the people to watch.
Knowing what to do in the event of a natural disaster. Floods, storms, heat, and fire are not new occurrences. As they’re arriving more frequently. Yet they’re supercharged and intense. But we’ve learned the skills, tools, and experience to defend one another. During the last 100 or 1000 years that humans have been wandering around on this rock.
Also, we know what to do in the event of a disaster. Floods, storms, heat, as well as fire, are things that have happened in the past.
That’s why we are inviting you to participate. Containing no recommendations for remedies to the impacts and vulnerabilities. As well as mitigation and adaptation reports will not be published until 2022.
Since there is a lot to this article and the news surrounding it. Difficult to hear and read about these objectively bad events, but we have facts. And also mountains of data and the expertise to deal with these shambles.
However, this report could be one of those tools. Encouraging you to email your government representative the summary for policymakers. so, there’s a good chance to dwell in one of the 195 countries that agreed to it.
Tell us what you’re planning to do with this knowledge in your community in the comments area. Also, you can use the atlas to see hat the current and future climate. Basically, having an impact on your area.
Do the models predict more drought in the future?
Take the information to your local community board, town halls, or governors. Or you can also join a local environmental group to look into the data together.
How can you put the information in this report to work in your community? And if the news surrounding this report is making you feel overwhelmed, then share it with your pals.
