Technologies are key in the urgent process of climate adaptation
Despite the agreements made at the recent COP 27 summit, we have to learn to live with the effects of climate change. Climate adaptation will be critical. Google Flood Hub and Internet of Things (IoT) can help with water management and support us to adapt to a changing climate.
Forests absorb 15.6 billion tonnes of CO2 every year
Forests cover 31% of the world’s land surface. They purify the air, filter water, prevent soil erosion, and act as an important buffer against climate change. But unsustainable human activities and climate change are causing deforestation and fragmentation, which is reducing forest cover.
Four innovative ways to store renewable energy without batteries
Global renewables capacity could rise as much in 2022-2027 as it did in the previous 20 years, according to the International Energy Agency. However, to get steady and uninterrupted supplies from renewables it has become increasingly important to develop more and better ways of storing energy.
Insights of Johan Rockström about the 16 tipping points
Professor Johan Rockström, Director of the Potsdam Institute for Climate Impact Research, mentioned during Davos that 9 of the 16 biophysical systems, or tipping points, that regulate the Earth’s climate are showing signs of instability. There is evidence that four of them are already at risk at 1.5°C.
Turning crises into opportunities to tackle long-term challenges
The 2023 Global Risks Report mentioned that this year’s top-rated crisis is energy, followed by inflation and food supplies. Within 10 years, climate change mitigation will top the list, followed closely by climate change adaptation and two other closely related risks – extreme weather events and biodiversity.
Historic biodiversity agreement to safeguard world’s climate
The UN Convention on Biological Diversity has reached a historic deal to protect the world’s lands and ocean. The agreement includes a commitment to protect 30% of land and water considered important for biodiversity by 2030. Currently, only 17% of terrestrial and 10% of marine areas are protected.
