*Climate change widespread, rapid, and intensifying – IPCC*
GENEVA, Aug 9 – Scientists are observing changes in the Earth’s climate
in every region and across the whole climate system, according to the
latest Intergovernmental Panel on Climate Change (IPCC) Report, released
today. Many of the changes observed in the climate are unprecedented in
thousands, if not hundreds of thousands of years, and some of the
changes already set in motion—such as continued sea level rise—are
irreversible over hundreds to thousands of years.
However, strong and sustained reductions in emissions of carbon dioxide
(CO2) and other greenhouse gases would limit climate change. While
benefits for air quality would come quickly, it could take 20-30 years
to see global temperatures stabilize, according to the IPCC Working
Group I report, Climate Change 2021: the Physical Science Basis,
approved on Friday by 195 member governments of the IPCC, through a
virtual approval session that was held over two weeks starting on July 26.
The Working Group I report is the first instalment of the IPCC’s Sixth
Assessment Report (AR6), which will be completed in 2022.
“This report reflects extraordinary efforts under exceptional
circumstances,” said Hoesung Lee, Chair of the IPCC. “The innovations in
this report, and advances in climate science that it reflects, provide
an invaluable input into climate negotiations and decision-making.”
Faster warming
The report provides new estimates of the chances of crossing the global
warming level of 1.5°C in the next decades, and finds that unless there
are immediate, rapid and large-scale reductions in greenhouse gas
emissions, limiting warming to close to 1.5°C or even 2°C will be beyond
reach.
The report shows that emissions of greenhouse gases from human
activities are responsible for approximately 1.1°C of warming since
1850-1900, and finds that averaged over the next 20 years, global
temperature is expected to reach or exceed 1.5°C of warming. This
assessment is based on improved observational datasets to assess
historical warming, as well progress in scientific understanding of the
response of the climate system to human-caused greenhouse gas emissions.
“This report is a reality check,” said IPCC Working Group I Co-Chair
Valérie Masson-Delmotte. “We now have a much clearer picture of the
past, present and future climate, which is essential for understanding
where we are headed, what can be done, and how we can prepare.”
Every region facing increasing changes
Many characteristics of climate change directly depend on the level of
global warming, but what people experience is often very different to
the global average. For example, warming over land is larger than the
global average, and it is more than twice as high in the Arctic.
“Climate change is already affecting every region on Earth, in multiple
ways. The changes we experience will increase with additional warming,”
said IPCC Working Group I Co-Chair Panmao Zhai.
The report projects that in the coming decades climate changes will
increase in all regions. For 1.5°C of global warming, there will be
increasing heat waves, longer warm seasons and shorter cold seasons. At
2°C of global warming, heat extremes would more often reach critical
tolerance thresholds for agriculture and health, the report shows.
But it is not just about temperature. Climate change is bringing
multiple different changes in different regions – which will all
increase with further warming. These include changes to wetness and
dryness, to winds, snow and ice, coastal areas and oceans. For example:
Climate change is intensifying the water cycle. This brings more intense
rainfall and associated flooding, as well as more intense drought in
many regions.
Climate change is affecting rainfall patterns. In high latitudes,
precipitation is likely to increase, while it is projected to decrease
over large parts of the subtropics. Changes to monsoon precipitation are
expected, which will vary by region.
Coastal areas will see continued sea level rise throughout the 21st
century, contributing to more frequent and severe coastal flooding in
low-lying areas and coastal erosion. Extreme sea level events that
previously occurred once in 100 years could happen every year by the end
of this century.
Further warming will amplify permafrost thawing, and the loss of
seasonal snow cover, melting of glaciers and ice sheets, and loss of
summer Arctic sea ice.
Changes to the ocean, including warming, more frequent marine heatwaves,
ocean acidification, and reduced oxygen levels have been clearly linked
to human influence. These changes affect both ocean ecosystems and the
people that rely on them, and they will continue throughout at least the
rest of this century.
For cities, some aspects of climate change may be amplified, including
heat (since urban areas are usually warmer than their surroundings),
flooding from heavy precipitation events and sea level rise in coastal
cities.
For the first time, the Sixth Assessment Report provides a more detailed
regional assessment of climate change, including a focus on useful
information that can inform risk assessment, adaptation, and other
decision-making, and a new framework that helps translate physical
changes in the climate – heat, cold, rain, drought, snow, wind, coastal
flooding and more – into what they mean for society and ecosystems.
This regional information can be explored in detail in the newly
developed Interactive Atlas interactive-atlas.ipcc.ch as well as
regional fact sheets, the technical summary, and underlying report.
Human influence on the past and future climate
“It has been clear for decades that the Earth’s climate is changing, and
the role of human influence on the climate system is undisputed,” said
Masson-Delmotte. Yet the new report also reflects major advances in the
science of attribution – understanding the role of climate change in
intensifying specific weather and climate events such as extreme heat
waves and heavy rainfall events.
The report also shows that human actions still have the potential to
determine the future course of climate. The evidence is clear that
carbon dioxide (CO2) is the main driver of climate change, even as other
greenhouse gases and air pollutants also affect the climate.
“Stabilizing the climate will require strong, rapid, and sustained
reductions in greenhouse gas emissions, and reaching net zero CO2
emissions. Limiting other greenhouse gases and air pollutants,
especially methane, could have benefits both for health and the
climate,” said Zhai.

*On this day in the history of global warming August 12, 2004*
August 12, 2004: Discussing a BusinessWeek story about the business
community's growing worries about global warming, the Washington
Monthly's Kevin Drum observes:
"Like national healthcare, I suspect that global warming will really get
taken seriously only when the business community finally demands it.
What BusinessWeek documents is only the first whispers of those demands,
but the endgame is already in sight."
