Despite the appearance of corroborating results from a team of researchers at Georgia Tech and the National Center for Atmospheric Research in the September 16 issue of Science, some researchers have said they are surprised by the magnitude of the intensity increases, which don't show up in existing climate-change theory or computer models.
Notable gaps in existing climate-finance mechanisms, including Adaptation Fund (AF) and Least Developed Countries Fund (LDCF), coupled with slow disbursement of the Green Climate Fund (GCF), poses major challenges for the most vulnerable countries like Timor-Leste to address massive impacts of climate change.
When TPU parameters were incorporated into existing climate models, the researchers found that it resulted in atmospheric carbon dioxide levels increasing faster than expected.
Multiple empirical studies report microevolutionary responses to climate in natural populations either along existing climate gradients or, less commonly, in response to temporal changes in climate (Hoffmann and Blows 1993; Huey et al. 2000; Davis and Shaw 2001; Ackerly 2003; Geber and Eckhart 2005; Jump and Penuelas 2005; Balanya et al. 2006; Reusch and Wood 2007; Gienapp et al. 2008).
Analog scenarios make use of existing climate information, either at the region in question (temporal analogs) or from another region that currently experiences a climate anticipated to resemble the future climate of the site under study (spatial analogs).
Second, GHG emission reduction policies can influence a range of major risk factors that contribute substantially to global disease burden, whereas climate change adaptation strategies result in health co-benefits predominantly by increasing resilience to existing climate variability.
A January study in the Journal of Geophysical Research: Atmospheres, for instance, concluded that existing climate models underestimate black carbon's climate-changing contribution by up to a factor of three as a result of data gaps in key regions.
Climate change adaptation further seems to become 'absorbed' in local climate change programs, where it is increasingly seen as an expansion of existing climate change mitigation strategies.
Both mitigation — the efforts to reduce greenhouse gas emissions — and adaptation to existing climate changes will be on the table at the critical climate negotiations in Paris this fall.
The climate sensitivity estimates in the existing climate models are all over the place currently, i.e. there is no consensus.
In Brasília, the chief foreign relations adviser to President Luiz Inácio Lula da Silva told reporters, "Considering the existing climate in the country, that would be the best solution". Amy Bracken contributed reporting for this article.
