These maps show the average of a set of climate model experiments projecting changes in surface temperature for the period 2050-2059, relative to the period from 1971-1999. The IPCC concluded that Global-mean surface warming by the end of the 21st century is likely to exceed 1.5 °C relative to 1850–1900 for all RCPs except RCP2.6. The range isn’t a projection; it’s more like a speed limit that influences projections. The NASA climate projections provide a detailed view of future temperature and precipitation patterns around the world at a 15.5 mile (25 kilometer) resolution, covering the time period from 1950 to 2100. URL. Carleton et al. With mild winters, little chance of frost, and warm, dry summers, the Napa Valley is a showpiece of wine production in California, the state that accounts for more than 90 percent of U.S. wine exports. In particular, we used downscaled CMIP5 climate projections prepared by the US Bureau of Reclamation (Brekke et al., 2013). The full estimates also reflect statistical uncertainty related to the underlying economic and health data. 27599, Available at NBER: http://www.nber.org/papers/w27599. Dealing with uncertainty. Damages are valued at an income-scaled value of statistical life (VSL) relying the U.S. EPA’s VSL estimate of $10.95 million (2019 USD). The target global mean temperature distributions for 2080-2099 used were identical to those of Rasmussen et al. To adapt and build resilience, up-to-date, credible and robust information on climate change and variability is needed to inform decision-making. However, with latest projections pointing to … The 11-terabyte dataset provides daily estimates of maximum and minimum temperatures and precipitation over the entire globe. The climate projection methodology is described in full in Rasmussen et al. (2016). As in that paper, potential temperature outcomes produced the probabilistic simple climate model but not represented within the downscaled CMIP5 dataset were represented by ‘model surrogates’, produced using linear pattern scaling, with residuals added to represent high-frequency variability and non-linearities. Lukas Brunner 1 , Angeline G. Pendergrass 2,1,a , Flavio Lehner 1,a , Anna L. Merrifield 1 , Ruth Lorenz 1 , and Reto Knutti 1 Carbon Brief has extracted data from around 70 peer-reviewed climate studies to show how global warming is projected to affect the world and its regions. 16, 2019 , 3:55 PM.

Global warming has raised global sea level about 8 inches since 1880, and the rate of rise is accelerating. Climate Change Studies: … These changes are based on the IS92a ("business as usual") projections of carbon dioxide and other greenhouse gas emissions during the next century, and essentially assume normal levels of economic growth and no significant steps are taken to combat global greenhouse gas emissions. The emissions that drive this warming are often called Baseline scenarios (‘Baselines’ in the above figure) and are taken from the IPCC AR5 Working Group III. Note: Global tide gauge projections are downloadable via this Surging Seas Risk Zone map. NASA has released data showing how temperature and rainfall patterns worldwide may change through the year 2100 because of growing concentrations of greenhouse gases in Earths atmosphere. But how accurate are they? (2020) use these results to model how adaptation affects the sensitivity of a population to extreme temperatures. The impacts of climate change at 1.5C, 2C and beyond. Global sea level has risen about 8 inches since reliable record keeping began in 1880. 2. Photograph: NASA/Corbis The North American region includes the United States and Canada, which rank number two and seven, in CO2 emissions globally (using 2008 data). The oceans are absorbing over 90% of the increased atmospheric heat associated with emissions from human activity.
