Global Warming
Human activity this century has increased the concentrations of atmospheric trace gases, which in turn has elevated global surface temperatures by blocking the escape of thermal infrared radiation. Natural climate variations are masking this temperature increase, but further additions of trace gases during the next 65 years could double or even quadruple the present effects, causing the global average temperature to rise by at least 1 °C and possibly by more than 5 °C. If the rise continues into the twenty-second century, the global average temperature may reach higher values than have occurred in the past 10 million years.
Climate model projections summarized in the latest IPCC report indicate that the global surface temperature is likely to rise a further 1.1 to 6.4 °C (2.0 to 11.5 °F) during the 21st century. The uncertainty in this estimate arises from the use of models with differing sensitivity to greenhouse gas concentrations and the use of differing estimates of future greenhouse gas emissions. An increase in global temperature will cause sea levels to rise and will change the amount and pattern of precipitation, probably including expansion of subtropical deserts.Warming is expected to be strongest in the Arctic and would be associated with continuing retreat of glaciers, permafrost and sea ice. Other likely effects include changes in the frequency and intensity of extreme weather events, species extinctions, and changes in agricultural yields. Warming and related changes will vary from region to region around the globe, though the nature of these regional variations is uncertain.As a result of contemporary increases in atmospheric carbon dioxide, the oceans have become more acidic, a result that is predicted to continue.
The scientific consensus is that anthropogenic global warming is occurring.Nevertheless, political and public debate continues. The Kyoto Protocol is aimed at stabilizing greenhouse gas concentration to prevent a "dangerous anthropogenic interference".As of November 2009, 187 states had signed and ratified the protocol.
Proposed responses to climate change include mitigation to reduce emissions, adaptation to the effects of global warming, and geoengineering to remove greenhouse gases from the atmosphere or block incoming sunlight.

• ¿Qué palabras se parecen al español? Human activity, concentrations, atmospheric, temperature, possibly, Natural, Climate,
• ¿Cuáles son las palabras en negrita, el titulo, subtitulo o gráficos que te ayudan a entender el texto? temperature, global warming.
• ¿De qué trata el texto? Lee el primer párrafo y el último o la ultimas ideas del último párrafo. El Calentamiento Global ha aumentado con las concentraciones de gases rastro atmosféricos, ocasionando que las temperatura se haya elevado por el bloqueo de la radiación infrarroja, en los próximos 65 años si continúan las remotas adiciones de gases podrían doblarse los efectos presentes ocasionando que la temperatura continúe elevándose en al menos 1°C y posiblemente en más de 5°C.

Íker Casillas Fernández, born May 20, 1981 in Móstoles, Madrid, Spain, is a Spanish football goalkeeper. He currently is Real Madrid's and Spain's first choice goalkeeper.
Born in Madrid in 1981, Casillas' entire career has been spent with his hometown club, whom he joined as an eight-year old. Part of the Spanish teams which won the UEFA-CAF Meridian Cup and FIFA World Youth Championship in 1999, his breakthrough year came in 1999/2000, when he replaced the injured Bodo Illgner and played in Madrid's UEFA Champions League triumph in an all-Spanish final against Valencia CF where his senior team mates Raúl González, Fernando Morientes and Steve McManaman scored in a 3-0 win. Loss of form subsequently allowed César Sánchez to take the number 1 jersey but Casillas reclaimed the limelight after substituting the veteran in the 2001/02 Champions League final against Bayer Leverkusen and preserving Madrid's 2-1 lead with a series of fine saves.
