Climate Change increases tree mortality worldwide

Climate Change increases tree mortality worldwide. To keep the climate system within conditions that guarantee the survival of the human species and most of those currently living on planet Earth, it is therefore necessary to quickly eliminate the emission of further greenhouse gases and remove those already in the atmosphere through so-called negative emissions.

Resolving the climate crisis therefore requires a strong commitment to equity and justice, to indigenous peoples and future generations, as well as to global change. Society can solve the climate crisis and avoid catastrophic climate change only by working together to overcome all divergences and making the climate crisis a top priority.

In this way, the 21st century can become one of renewed equity, justice and sustainability.

The Climate Change Risks to Global Forest Health: Emergence of Unexpected Events of Elevated Tree Mortality Worldwide study, published on the Annual review of plant biology, makes an interesting retrospective on a topic closely connected with the climate crisis.

The researchers said: "Recent observations of elevated tree mortality following climate extremes, like heat and drought, raise concerns about climate change risks to global forest health. We currently lack both sufficient data and understanding to identify whether these observations represent a global trend toward increasing tree mortality.

Here, we document events of sudden and unexpected elevated tree mortality following heat and drought events in ecosystems that previously were considered tolerant or not at risk of exposure. These events underscore the fact that climate change may affect forests with unexpected force in the future.

We use the events as examples to highlight current difficulties and challenges for realistically predicting such tree mortality events and the uncertainties about future forest condition. Advances in remote sensing technology and greater availably of high-resolution data, from both field assessments and satellites, are needed to improve both understanding and prediction of forest responses to future climate change."
