WORLD WORLDWIDE SOUTH-AMERICA BRAZIL - news journal UPDATE - (en) Brazil, Capixaba: FACA: Heatwaves threaten to collapse ecosystems, including the Amazon (ca, de, it, pt, tr)[machine translation]

 Warming temperatures will have a range of consequences, including

declining fertility, a climate science report predicts. ---- Rising
global temperatures are disrupting vital ocean processes, pushing the
Amazon to the brink of large-scale collapse and putting an unborn
generation at risk, increasing the chances of pregnancy complications.
---- This is one of the conclusions of the annual report '10 New
Insights in Climate Science', released by The Earth League, an
international consortium of scientists and climate experts.

The work reveals the impact of climate change that could reverse decades
of progress in maternal and reproductive health, contribute to more
extreme and damaging El Niño events, and threaten the Amazon, one of the
most important natural carbon sinks, along with seven other crucial
climate insights.

The report is designed to inform policymakers with the latest available
knowledge. The scientific findings have been synthesized to highlight
the policy implications that could guide negotiations at COP29, which
will take place in Azerbaijan in November, and inform national and
international policy.

"The report confirms challenges on a planetary scale, from rising
methane emissions to the vulnerability of critical infrastructure," says
Johan Rockström, co-chair of The Earth League and director of the
Potsdam Institute for Climate Impact Research in Germany.

"It shows that rising heat, unstable oceans and the potential upheaval
of the Amazon could push parts of our planet beyond habitable limits.
However, it also offers clear pathways and solutions, demonstrating that
with urgent and decisive action, we can still avoid uncontrollable
outcomes."

"The report reveals the scope of the impacts of climate change on
different ecological, economic and social systems. With fewer habitable
environments, population migration could intensify. There is also a
significant impact on maternal health, which can last for generations,"
says Mercedes Bustamante, a professor at UnB (University of Brasília)
and a member of the publication's editorial board. According to her, in
Brazil, there is a link between the country's actions to reduce
deforestation and degradation of the Amazon and international
initiatives to reduce greenhouse gas emissions, which affect the biome
in a synergistic way. Despite the intensifying global challenges, she
emphasized that there is a set of policies and solutions that can be
implemented to effectively address climate change. In the face of
threats to maternal health, these solutions include, for example, gender
equity and climate justice actions. The report also highlights two major
challenges for the natural world. Ocean warming persists and sea surface
temperature records continue to be broken, leading to more severe El
Niño events than previously understood. According to the report,
projected additional global economic losses due to increased frequency
and intensity of El Niño events resulting from global warming could
reach nearly $100 trillion over the 21st century.
The '10 New Insights in Climate Science' series, launched with the
UNFCCC (United Nations Framework Convention on Climate Change) at COPs
since 2017, is a collaborative initiative by Future Earth, The Earth
League and the World Climate Research Programme, synthesizing key recent
developments in climate change research.

This year's report represents the collective effort of more than 80
leading researchers from 45 countries.

The 10 Insights

Methane: Since 2006, methane levels have increased dramatically.
Cost-effective solutions already exist, but stringent policies are
needed to reduce its emissions from the fossil fuel, waste and
agriculture sectors.

Air pollution: Reducing air pollution improves public health, but has
complex climate impacts, requiring mitigation and adaptation strategies
to take this into account.
Extreme heat: Rising temperatures and humidity levels are making parts
of the planet uninhabitable. Heat response plans need to prioritize the
most vulnerable groups.
Maternal and reproductive health: Weather extremes are harming maternal
health, threatening decades of progress. Solutions need to integrate
gender equity and climate justice.
Ocean change: Warming oceans are exacerbating El Niño events and
threatening the stability of marine systems, potentially causing massive
global economic losses.

Amazon Resilience: Biocultural diversity helps the Amazon to resist
climate change, but these local actions need to be complemented by
global emissions reductions.
Critical Infrastructure: Infrastructure is increasingly vulnerable to
climate disasters. AI tools can help make it more resilient.
Urban Development: Few cities integrate mitigation and adaptation into
their climate plans. An approach that combines social, ecological and
technological factors can help resilient development.
Energy Transition Minerals: Demand for transition minerals is
increasing, as are supply chain risks. Better governance is essential
for a just transition.
Climate Justice: Public acceptance of climate policies depends on their
perception of fairness. Excluding citizens from the formulation process
can generate resistance.
