Integrating environmental effects into a bookkeeping model finds an increase in CO2 emissions from land-use change by 14% in 2012–2021. It further shows that state-of-the-art process-based models overestimate the natural terrestrial CO2 sink by 23%. Lea Dorgeist , Clemens Schwingshackl & Jul...
Ocean-emitted iodine leads to new particle formation (NPF) in the atmosphere5,6. Recent field observations have demonstrated that iodine is a significant driver of NPF in the central Arctic3and is currently considered a potentially relevant source of CCN3—from which marine clouds originate—that ...
By contrast, climate models have been systematically over-forecasting temperature rises this century, demonstrating that climate scientists know much less about the climate system than they would have us believe. Needless to say, if the models are wrong about the weather we’ve already had, why ...
Information about climate change impacts, early warning systems, and adaptation options saves lives and empowers governments and communities to take timely and appropriate actions to increase climate resilience and address climate-related mobility. The U.S. Government advances observations, models, and fo...
Under a higher emissions scenario, however, the 21st century would see much more severe consequences of climate change. Global climate models have given climate scientists a set of expectations as to what the future could hold, both for the Earth at large and for specific regions. Climate ...
are part of the past, vested-interest, old business models, old ways of exploiting the natural world and society. I think that’s really untenable. And if we have this massive movement, every single citizen making decisions on those values, I think we can see chan...
Here we present a spatially explicit approach which incorporates both climate and land-use change models to identify areas of refugia for bird species in the Brazilian Cerrado. Specifically, our objectives were: (1) to identify major risk areas and possible refugia for bird species in the Cerrado...
Climate change threatens the health and survival of urban trees and the various benefits they deliver to urban inhabitants. Here, we show that 56% and 65% of species in 164 cities across 78 countries are currently exceeding temperature and precipitation conditions experienced in their geographic rang...
When considering flood hazard projections derived from only the central 50% of climate model ensemble members (that is, ignoring outlier simulations), the variability between models representing the present day is over double the magnitude of the change signal to 205023. In simpler terms, increased...
[71] state that climate change impact modelling needs to include cross-sectoral interactions, as assessments often apply models of individual sectors such as agriculture, forestry, and water use without considering interactions between these sectors, which is likely to lead to misrepresentation of ...
