In the aftermath of a drought, forests weather another dry spell surprisingly well.
. That’s important because of the many resources that forests provide, including their ability to sequester about a quarter of the carbon dioxide that humans put into the atmosphere every year.
When the researchers looked at forests that just experienced the 2012–2015 drought, they found that over 50 percent of forested areas showed evidence of die-off. But when Norlen and Goulden analyzed forests that had weathered both droughts, they were surprised to find that only 13 percent of those forested areas showed evidence of die-off after the second drought.

Indicators of Global Climate Change 2022: annual update of large-scale indicators of the state of the climate system and human influenceAbstract. Intergovernmental Panel on Climate Change (IPCC) assessments are the trusted source of scientific evidence for climate negotiations taking place under the United Nations Framework Convention on Climate Change (UNFCCC), including the first global stocktake under the Paris Agreement that will conclude at COP28 in December 2023. Evidence-based decision-making needs to be informed by up-to-date and timely information on key indicators of the state of the climate system and of the human influence on the global climate system. However, successive IPCC reports are published at intervals of 5–10 years, creating potential for an information gap between report cycles. We follow methods as close as possible to those used in the IPCC Sixth Assessment Report (AR6) Working Group One (WGI) report. We compile monitoring datasets to produce estimates for key climate indicators related to forcing of the climate system: emissions of greenhouse gases and short-lived climate forcers, greenhouse gas concentrations, radiative forcing, surface temperature changes, the Earth's energy imbalance, warming attributed to human activities, the remaining carbon budget, and estimates of global temperature extremes. The purpose of this effort, grounded in an open data, open science approach, is to make annually updated reliable global climate indicators available in the public domain (https://doi.org/10.5281/zenodo.8000192, Smith et al., 2023a). As they are traceable to IPCC report methods, they can be trusted by all parties involved in UNFCCC negotiations and help convey wider understanding of the latest knowledge of the climate system and its direction of travel. The indicators show that human-induced warming reached 1.14 [0.9 to 1.4] ∘C averaged over the 2013–2022 decade and 1.26 [1.0 to 1.6] ∘C in 2022. Over the 2013–2022 period, human-induced warming has been increasing at an unprecedented rate of over 0.2 ∘C per decade. This high rate of warming is caused by a combination of greenhou

A multimodel analysis of post-Glasgow climate targets and feasibility challenges - Nature Climate ChangeAlthough many countries have strengthened their emissions reduction pledges, their ability to limit the warming outcomes is still in question. A multimodel analysis demonstrates that these trajectories are in line with the 2 °C target but countries probably face feasibility challenges to achieve them.

Why Arnold Schwarzenegger Wants Us To Focus On 'Pollution' Rather Than 'Climate Change' - CleanTechnicaArnold Schwarzenegger has been one of the few Republican champions of climate action. That’s not to say he’s been perfect on the topic, but he has been serious about wanting to address global heating and disruptive climate change. He’s also been a top-notch climate communicator. Talking about climate change in an effective way is a […]
