NASA Finds Summer 2024 Hottest to Date
Summary
The summer months of June, July, and August were ones of unprecedented temperatures according to the historical data held at NASA. New research has further increased the certainty of temperature measurements.
Key Points
"Data from multiple record-keepers show that the warming of the past two years may be neck and neck, but it is well above anything seen in years prior, including strong El Niño years."
A new statistical ensemble approach is used to reduce local measurement variance and increase certainty.

Relevance to Digital Preservation
Raised temperatures contribute to a variety of destabilizing effects like extreme weather which threaten cultural heritage institutions.

Responsible carbon dioxide removals and the EU’s 2040 climate target
Summary
The European Union's 2040 climate target of a 90% reduction of greenhouse gases relative to 1990 levels assumes that carbon dioxide removal (CDR) will play an important role. Much research and modelling have been devoted to the effectiveness of various CDR techniques, though much is still unknown.
Key Points
Realistic potentials for CDR are still not known.
Most CDR approaches have downsides or limitations so a portfolio of options is needed.
Source
Environmental Research Letters is a peer-reviewed, open-access journal.
Relevance to Digital Preservation
CDR has the potential to be an important tool in mitigating climate change and EU policy could influence other countries.
