One study of a research project at the University of Hamburg, the Achieving the 1.5 degree target remains implausibleThe authors refer, among other things, to the Behavior of companies, consumption trends and investments in fossil fuels.
This is clear from the “Hamburg Climate Futures Outlook 2024“, which has been published since 2021 and social developments examinedwhich Climate protection influence. “It will again invested heavily in oil, gas and coal“, said co-author and sociology professor Anita Engels.

“If adaptation is not thought through, side effects can undermine success,” said co-author and geography professor Beate Ratter. Coastal protection measures may initially help with flooding, but in the long term they could wash away sediment and damage coral reefs. Forests reforested with monocultures are also particularly susceptible to pest infestation.
Regarding the last category, sustainable adaptation, it says: “Such measures have a long-term effect, reduce risks and are co-designed and supported by the local population.” The scientists found no so-called sustainable adaptation in any of the casesHowever, there are initial approaches at three locations: Hamburg, North Friesland and Ho Chi Minh City (formerly Saigon, Vietnam).
