Climate modelling is becoming an ever more sophisticated science, but
there are still more than 1200 different future pathways outlined in the
latest IPPC report, depending on what we humans choose to do next. Now a
team of journalists and scientists has assessed those pathways to find
out if any of them is genuinely achievable.

*Climate-friendly, affordable housing: Is it possible?*
Gero Rueter
January 6, 2023
Our homes protect us from the rain and cold. But heating them requires a
lot of energy, and building them is bad for the climate as well. DW
looks at more environmental ways of living.
Buildings are massive emitters. Their heating, electricity and
construction cause about 10 billion metric tons of CO2 per year
worldwide. On average, that's about 1.3 tons of carbon dioxide per
person every year.
In 2021, the buildings and construction sector was responsible for 37%
of energy-related CO2 emissions, surpassing the transportation sector
(22%), according to a UN study.
So how can we reduce these high emissions? And what measures can we take
to ensure sustainable, affordable and comfortable living?
*More housing, more CO2*
The world's population has grown significantly over the past 100 years,
and so have housing needs. And, as income levels have soared, there has
been a rise in the number of people living alone. But across the world,
there are huge variations in the amount of living space.
A person in Nigeria, for example, uses 6 square meters (65 square feet)
of living space on average. That number goes up to 18 in Turkey, 24 in
Brazil, 30 in China, 38 in the European Union and 75 square meters in
the United States.
In Germany, the average living space per person has more than tripled
since 1950 — rising from 15 square meters to 48. Older empty nesters
tend to have the most room, with senior citizens having an average of 60
square meters per person.
The more apartments and houses there are, the more energy is needed for
heating and electricity — and the more CO2 is produced by these new
buildings.
Older buildings need a particularly high amount of energy for heating,
which can become expensive. But they can save up to 90% of energy with
insulation and modern ventilation systems. And heating costs can also go
down if less room is used.
*How do we heat affordably in a climate-neutral way?*
Biogas, wood or wood pellets are a few climate-friendly alternatives to
fossil fuels. But these resources are becoming increasingly scarce and
expensive, so experts also recommend heat pumps. These draw heat from
the ground or air and are powered with electricity. They can generate up
to 7 kilowatt hours (kWh) of heat energy from 1 kWh of electricity.
Heat pumps do not produce harmful particulate matter and, if green
electricity is used, no CO2. In Scandinavia, buildings have long been
heated with heat pumps and district heating is operated with large ones.
In combination with solar thermal energy, biomass and deep geothermal
energy, some of these networks are close to being climate-neutral.
*Producing your own solar power*
Energy-efficient heat pumps, fridges and LEDs can also lower the power
consumption of buildings. Affordable electricity can even be generated
at the house itself with photovoltaic roofs and facades.
In Germany, solar panels for the roof can generate solar power for less
than 0.10€ ($0.11) per kWh. That's not even a quarter of the price one
would normally pay for electricity from the grid: an average of 0.40€
per kWh. Solar panels pay for themselves in five to 15 years, after
which they generate free electricity for around two decades.
*Renewable material instead of concrete, steel and plastic*
A lot of CO2 is emitted during the construction of buildings, some 0.5
to 0.8 tons per square meter of living space. That's about 50 to 80 tons
of CO2 for the construction of a new 100-square-meter apartment. In
comparison, India emits 2 tons of CO2 per capita per year.
Emissions are mainly caused by the production of cement, lime and gypsum
(25%), by the construction itself (10%) and by the production of
building materials such as insulation (8%) and metals (8%).
Alternative building materials such as wood and renewable insulating
options like straw can drastically reduce CO2 emissions from
construction sites. In Germany, it could slash them by 50%.
*Refurbishing instead of building*
Upgrading older units instead of building new ones also saves CO2 and
reduces expenses. Renovation usually costs around a quarter less than
building a new building, meaning emissions from construction and
operation can be more than halved.
That's why architects, scientists and environmental associations want
city planners and builders to rethink their designs. They say demolition
and new construction should be avoided wherever possible, and
refurbishing older buildings should become the norm.
*Less living space to protect the climate?*
Considering the housing shortage and the climate crisis, experts also
want society and politicians to rethink their priorities.
"The area of land on which people in Germany live today would be
sufficient for 200 million people — if they were content with an area
that was common in the 1960s," said sociologist Maike Böcker of the
Institute for Cultural Studies in Essen, in western Germany.
Germany currently has a population of 83 million people; in 2022, the
global population surpassed 8 billion.
In a 2020 study, the Wuppertal Institute for Climate, Environment and
Energy called for "intelligent and flexible" ways of using living space.
The German think tank said this is necessary to curb growing demand and
keep global heating to 1.5 degrees Celsius (2.7 degrees Fahrenheit).
Meanwhile, Austria's Graz University of Technology has modeled a
scenario in which global energy demand falls by 40% — despite the
growing population — to comply with the 1.5-degree limit. The
researchers recommend a worldwide average of 30 square meters of living
space per person.
*More social contacts for better living*
Experts also see potential for senior citizens to cut down on living
space. In industrialized countries like Germany, many older single
people or couples live in large apartments or houses after their
children move out, though these homes are often not equipped to meet the
needs of the elderly. At the same time, there is a lack of living space
for young families, especially in cities.
This is where targeted advice and offers can help, according to urban
planner and economist Daniel Fuhrhop.
"They could move into smaller apartments or renovate their homes to add
an additional dwelling unit," he said. "They could also sublet or live
with other people. There are many great, tried-and-tested options."
Some universities now arrange for students to pay lower rents by living
with seniors and helping them with household chores. Housing projects
with small, individual living units paired with communal gardens,
workshops, studios as well as laundry and fitness rooms are also
becoming increasingly popular.
In this model, office space and guest rooms can be booked for a certain
period of time at a reasonable price. Many residents appreciate these
shared quarters. It's a way for them to spend time together, get to know
each other better and to support each other.

*What's New?*
The warming Arctic reveals shifting seasons, widespread disturbances,
and the value of diverse observations
Shifting seasons and climate-driven disturbances, such as wildfires,
extreme weather, and unusual wildlife mortality events, are becoming
increasingly difficult to assess within the context of what has been
previously considered normal.
*About the Arctic Report Card*
Issued annually since 2006, the Arctic Report Card is a timely and
peer-reviewed source for clear, reliable and concise environmental
information on the current state of different components of the Arctic
environmental system relative to historical records.
The Report Card is intended for a wide audience, including scientists,
teachers, students, decision-makers and the general public interested in
the Arctic environment and science.
A significant increase in Arctic precipitation since the 1950s is now
detectable across all seasons. Wetter-than-normal conditions were
observed from October 2021 through September 2022, in what was the 3rd
wettest year of the past 72 years...

*If Science is to Save Us.* 1st Edition 2022
by Martin Rees (Author)
There has never been a time when ‘following the science’ has been more
important for humanity. At no other point in history have we had such
advanced knowledge and technology at our fingertips, nor had such
astonishing capacity to determine the future of our planet.
But the decisions we must make on how science is applied belong outside
the lab and should be the outcome of wide public debate. For that to
happen, science needs to become part of our common culture. Science is
not just for scientists: if it were, it could never save us from the
multiple crises we face. For science can save us, if its innovations
mesh carefully into society and its applications are channelled for the
common good.
As Martin Rees argues in this expert and personal analysis of the
scientific endeavour on which we all depend, we need to think globally,
we need to think rationally and we need to think long-term, empowered by
twenty-first-century technology but guided by values that science alone
cannot provide.

/[ State of Hawaii has been planning for sea level rise ]/
*DLNR NEWS RELEASE-UPDATED HAWAII SEA LEVEL RISE REPORT RELEASED*
Posted on Dec 31, 2022 in Latest Department News, Newsroom
(HONOLULU) – New science shows increased need for cross jurisdictional
coordination, funding, and capacity for sea level rise action as
outlined in an updated report by the Hawai‘i State Climate Commission.
First released in 2017, the Hawai‘i Sea Level Rise Vulnerability and
Adaptation Report, 2022-update addresses the threat posed by climate
change to public health, natural resources, economic well-being, and the
environment of Hawai‘i. It also assesses progress made over the past
five years in preparing the state for the impacts of sea level rise.
“The impacts of sea level rise do not stop at our shorelines. It is
important that we take a holistic approach and continue coordinated
planning for the future now,” said Amy Wirts, Hawai‘i Sea Grant
Extension Agent at the DLNR Office of Conservation and Coastal Lands (OCCL).
The updated report describes progress toward addressing the 2017
report’s recommendations and gives future recommendations toward urgent
actions that need to be set as a priority in the next five years. It
also includes local and global updates on sea level rise including
trends, observations and predictions, accomplishments and progress,
coastal impacts, and guidance documents.
“Sea levels will rise for centuries to millennia due to continuing
deep-ocean warming and ice-sheet melt and will remain elevated for
thousands of years. In Hawai‘i, we are experiencing the impacts of sea
level rise with growing frequency. These include flooding, coastal
erosion, extreme tides, drainage failure, wave overtopping, and more.
Unless we accelerate adaptation efforts, these hazards may grow beyond
our capacity to manage them,” said Dr. Charles Fletcher, Director of
the Climate Resilience Collaborative at the University of Hawai‘i at
Mānoa and Interim Dean of the School of Ocean and Earth Science and
Technology.
The report highlights recent enhancements to laws, community engagement,
policies, and regulations, including to the Coastal Zone Management Act
(CZMA), real estate disclosure requirements, environmental assessments,
and in community planning addressing increasing threats to development
while keeping cultural and natural resources safe. The report also
highlights the need for continued focus on developing a range of
adaptation tools accessible to the people of Hawai‘i in an equitable way.
“Equity is the core mission of the commission. It is going to take
investment and collaboration from all of us to make sure this happens.
That is why we are so grateful for the hard work of the University of
Hawai`i Sea Grant College Program, and the Climate Resilience
Collaborative for helping the commission put this update together,” said
DLNR Chair Suzanne Case.
