    Christians are also geographically widespread — so far-flung, in fact, that no single continent or region can indisputably claim to be the center of global Christianity. A century ago, this was not the case. The number of Christians around the world has nearly quadrupled in the last years, from about million in to more than 2 billion in This apparent stability, however, masks a momentous shift. At the same time, Christianity has grown enormously in sub-Saharan Africa and the Asia-Pacific region, where there were relatively few Christians at the beginning of the 20th century. Christianity today — unlike a century ago — is truly a global faith. See world maps weighted by Christian population in and

    In NAE at the request of NSF, convened a diverse international panel of some of the most accomplished engineers and scientists of their generation. The panel did not attempt to include every important goal for engineer- ing. Rather, it chose the problems we must solve to ensure survival of a livable Earth and the well-being of its inhabitants.

His idea: Use chemical reactions improved or new materials will enable continual a single memory, to grow switches and wires that assemble advances in everything from cars and planes to with one bit stored themselves into circuits. Working with col- the buildings we live in. The future is now: Flying drones that deliver packages and cars that drive themselves are already being tested, while virtual reality software helps train aviators both to fly a plane and to jump out of it.

    Imagine similar giant leaps in sensors, communications capabilities, displays, software, batteries, and mechanical actuators. Already, smart devices can answer simple inquiries and understand simple commands. Some of these devices will fail in the market, but others will hit the sweet spot that delights consumers and improves or enhances their lives.

Can cybersecurity efforts not only keep the hackers University of at bay but also keep criminals and terrorists in check? Can we find a balance between hyperconnection and personal privacy that is acceptable to most people?

    Engineering Ideas into Reality 49 Making Energy Sustainable I ntelligent, hyperconnected devices, 3-D printers, and other technologies will bring surprises, meet unanticipated needs, and change our lives in ways that are hard to imagine. But some aspects of the future are easier to predict. To create a better, richer, and healthier future for all people and nations, we know we must tackle and solve problems that are already obvious now.

    At the dawn amounts of salty water. This will be particularly pronounced in tropical and high-latitude regions, which are also expected to experience overall increases in precipitation. The amount of precipitation falling in tropical storms is also likely to increase. The figure to the right shows projected regional differences in precipitation under two emission scenarios.

    Southern areas, especially the Southwest, are projected to become drier. Heavy downpours that currently occur about once every 20 years are projected to occur between twice and five times as frequently by , depending on location. Climate models project an increase in the number of the strongest Category 4 and 5 hurricanes, as well as greater rainfall rates in hurricanes.

    The strongest cold-season storms are projected to become stronger and more frequent. For example, in winter and spring, climate models agree that northern areas in the United States are likely to get wetter and southern areas drier. There is less confidence in exactly where the transition between wetter and drier areas will occur. Confidence in the projected changes is highest in the areas marked with diagonal lines. The changes in white areas are not projected to be larger than what would be expected from natural variability.

    National Climate Assessment , Top of Page Future ice, snowpack, and permafrost Arctic sea ice is already declining.

    Over the next century, it is expected that sea ice will continue to decline, glaciers will continue to shrink, snow cover will continue to decrease, and permafrost will continue to thaw. Potential changes to ice, snow, and permafrost are described below. These maps show projected losses of sea ice in the Arctic and Antarctica.

    The maps in a show the average ice concentration the relative area covered by sea ice from The maps in b and c show climate model simulations of sea ice thickness in February and September near the end of the 21st century under low b and high c emission scenarios. In the Arctic, February is projected to have less ice more blue ; September is projected to be nearly ice-free almost all blue.

    The projected changes in Antarctic sea ice are more subtle.

    The coastal sections of the Greenland and Antarctic ice sheets are expected to continue to melt or slide into the ocean. If the rate of this ice melting increases in the 21st century, the ice sheets could add significantly to global sea level rise.

    The rate of melting is expected to continue to increase, which will contribute to sea level rise. Snowpack is expected to decrease in many regions. Changes in ice sheets are currently expected to account for 1. The orange line at right shows the currently projected range of sea level rise of 1 to 4 feet by ; the wider range 0. Regional and local factors will influence future relative sea level rise for specific coastlines around the world. For example, relative sea level rise depends on land elevation changes that occur as a result of subsidence sinking or uplift rising.

    Assuming that these historical geological forces continue, a 2-foot rise in global sea level by would result in the following relative sea level rise: [4] 2. As ocean acidification increases, the availability of calcium carbonate will decline. Calcium carbonate is a key building block for the shells and skeletons of many marine organisms.

    This change is measured on the pH scale, with lower values being more acidic. The pH level of the oceans has decreased by approximately 0. Richmond, and Gary W.
