*IPCC Climate Change Reports: Why They Matter to Everyone on the Planet*
The United Nations reports warn that dire impacts from climate change 
will arrive sooner than many expect. Here’s why we should follow their 
advice, and how the reduction of each ton of emissions can make a 
difference.
January 24, 2022
You’d be forgiven for losing track of all the reports on climate change. 
There are a lot—each seemingly more dire than the last. But perhaps none 
are more important than those released by the United Nations’ 
Intergovernmental Panel on Climate Change (IPCC), a group made up of 
thousands of unpaid scientist volunteers from around the world. In 
recent years, the IPCC’s reports have sounded the alarm with increasing 
clarity: We must cut emissions sharply and immediately to avoid the most 
catastrophic effects of a warming planet. Here’s a look at how the IPCC 
came to be the international leading authority on climate, the panel’s 
latest findings—and why it’s so critical that our leaders pay attention...

What are the important findings of the IPCC report?
Widespread, rapid, and intensifying: Those were the words used by the 
IPCC to describe climate change at the release of this August 2021 
report—the most comprehensive look at present and future climate impacts 
to date. Its conclusions, based on the latest generation of climate 
models, were clear: “Observed changes in the atmosphere, oceans, 
cryosphere, and biosphere provide unequivocal evidence of a world that 
has warmed,” the report says—and human activity is “indisputably” the cause.
The report lays out five possible scenarios—–from better to worse to 
apocalyptic—–that correspond to different timelines of climate action 
and their predicted degrees of warming. Under even the most optimistic 
scenario, one in which the world bands together to slash emissions 
immediately, the world can avoid the most catastrophic version of the 
climate crisis but will continue to warm until at least mid-century, due 
to the impact of past emissions. “Some of the changes already set in 
motion—such as continued sea level rise—are irreversible over hundreds 
to thousands of years,” the report says. That means we can expect 
climate impacts, from storms to sweltering temperatures, to get worse 
before they get better, though these interactions are complex and can 
vary by region...
- -
The conclusions of the IPCC’s “Global Warming of 1.5° C” special report 
were startling: A half degree more of warming would mean substantially 
more poverty, extreme heat, sea level rise, habitat and coral reef loss, 
and drought. And we cannot prevent this unless we act immediately to cut 
emissions deeply. The 2018 report confirmed what those vulnerable 
nations feared to be true: Every tenth of a degree of warming has grave 
consequences.

Limiting global warming to 1.5 degrees Celsius, rather than 2 degrees, 
“could reduce the number of people exposed to climate-related risks and 
susceptible to poverty by up to several hundred million by 2050,” the 
report states. At 1.5 degrees Celsius, the number of people across the 
globe at risk of inadequate water supplies could be 50 percent lower 
than at 2 degrees.

*Trenberth: Oceans warming for 60 years with no end anywhere in sight*
By KEVIN TRENBERTH
Of the University of Auckland

The world’s oceans are hotter than ever recorded, and their heat has 
increased each decade since the 1960s. This relentless increase is a 
primary indicator of human-induced climate change.

As oceans warm, their heat supercharges weather systems, creating more 
powerful storms and hurricanes, and more intense rainfall. That 
threatens human lives and livelihoods as well as marine life.

The oceans take up about 93% of the extra energy trapped by the 
increasing greenhouse gases from human activities, particularly burning 
fossil fuels. Because water holds more heat than land does and the 
volumes involved are immense, the upper oceans are a primary memory of 
global warming.

I explain this in more detail in my new book “The Changing Flow of 
Energy Through the Climate System.”

Our study provided the first analysis of 2021’s ocean warming, and we 
were able to attribute the warming to human activities. Global warming 
is alive and well, unfortunately.

*If greenhouse gas emissions slowed, would the ocean cool down?*
In the oceans, warm water sits on top of cooler denser waters. However, 
the oceans warm from the top down, and consequently the ocean is 
becoming more stratified. This inhibits mixing between layers that 
otherwise allows the ocean to warm to deeper levels and to take up 
carbon dioxide and oxygen. Hence it impacts all marine life.

We found that the top 500 meters of the ocean has clearly been warming 
since 1980; the 500-1,000 meter depths have been warming since about 
1990; the 1,000-1,500 meter depths since 1998; and below 1,500 meters 
since about 2005.
The slow penetration of heat downward means that oceans will continue to 
warm, and sea level will continue to rise even after greenhouse gases 
are stabilized...

On December 10, 1985, the Senate Environment and Public Works 
Subcommittee on Hazardous Wastes and Toxic Substances held a hearing to 
discuss how the greenhouse effect might change the global climate system 
and possible solutions.
Invited witnesses were:

    Dean Abrahamson Professor, University of Minnesota
    Ralph J. Cicerone Director, National Center for Atmospheric Research
    Gordon MacDonald Chief Scientist, MITRE Corporation

*Improving climate model projections of carbon and heat uptake in the 
Antarctic Ocean*
by NORCE
JANUARY 24, 2022
In a new study in Nature Communications, researchers unveil a new 
relationship for climate models linking both carbon and heat uptake with 
the water-column stability in the Southern Ocean—also called the 
Antarctic Ocean...
- -
The Ocean is a powerful mitigator of climate change. It absorbs about 25 
percent of the CO2 emitted by humans into the atmosphere (anthropogenic 
carbon) and 90 percent of the excess heat caused by global warming...
- -
Using a powerful and recent statistical methodology as well as 
observational data describing today's water-column stability, the new 
relationship permits to reduce the uncertainty of future estimates of 
the anthropogenic carbon uptake by up to 53 percent and the excess heat 
uptake by 28 percent.

These results highlight that, for this region, an improved 
representation of the water-column stability in climate models is key to 
improving climate change projections.

**On this day in the history of global warming January  25, 2007*

January 25, 2007: The Washington Post reports on a fundamentalist 
Christian parent's crusade to have "An Inconvenient Truth" restricted 
from being shown in a suburban Seattle middle school:

"Frosty E. Hardison is neither impressed nor surprised that 'An 
Inconvenient Truth,' the global-warming movie narrated by former vice 
president Al Gore, received an Oscar nomination this week for best 
documentary.

"Liberal left is all over Hollywood,' he grumbled a few hours after the 
nomination was announced.

"Hardison, a parent of seven here in the southern suburbs of Seattle, 
has himself roiled the global-warming waters. It happened early this 
month when he learned that one of his daughters would be watching 'An 
Inconvenient Truth' in her seventh-grade science class.

"'No you will not teach or show that propagandist Al Gore video to my 
child, blaming our nation -- the greatest nation ever to exist on this 
planet -- for global warming,' Hardison wrote in an e-mail to the 
Federal Way School Board. The 43-year-old computer consultant is an 
evangelical Christian who says he believes that a warming planet is 'one 
of the signs' of Jesus Christ's imminent return for Judgment Day.

"His angry e-mail (along with complaints from a few other parents) 
stopped the film from being shown to Hardison's daughter.

The teacher in that science class, Kay Walls, says that after Hardison's 
e-mail she was told by her principal that she would receive a 
disciplinary letter for not following school board rules that require 
her to seek written permission to present 'controversial' materials in 
class.

The e-mail also pressured the school board to impose a ban on screenings 
of the film for the district's 22,500 students.

"The ban, which the school board says was merely a 'moratorium,' was 
lifted Tuesday night, subject to rigorous conditions. Still, the action 
has appalled the film's producers and triggered a ferocious national 
backlash.

"Members of the school board say they have been bombarded by thousands 
of e-mails and phone calls, many of them hurtful and obscene, accusing 
them of scientific ignorance, pandering to religion and imposing prior 
restraint on free speech."
