Global warming is the increase in the average temperature of the Earth's near-surface air and oceans since the mid-20th century and its projected continuation. Global surface temperature increased 0.74 ± 0.18 °C (1.33 ± 0.32 °F) during the last century. The Intergovernmental Panel on Climate Change (IPCC) concludes that most of the observed temperature increase since the middle of the 20th century was caused by increasing concentrations of greenhouse gases resulting from human activity such as fossil fuel burning and deforestation. The IPCC also concludes that variations in natural phenomena such as solar radiation and volcanoes produced most of the warming from pre-industrial times to 1950 and had a small cooling effect afterward.These basic conclusions have been endorsed by more than 40 scientific societies and academies of science, including all of the national academies of science of the major industrialized countries.

Climate model projections summarized in the latest IPCC report indicate that the global surface temperature will probably rise a further 1.1 to 6.4 °C (2.0 to 11.5 °F) during the twenty-first 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. Some other uncertainties include how warming and related changes will vary from region to region around the globe. Most studies focus on the period up to the year 2100. However, warming is expected to continue beyond 2100 even if emissions stop, because of the large heat capacity of the oceans and the long lifetime of carbon dioxide in the atmosphere.

Halloween (also spelled Hallowe'en) is an annual holiday celebrated on October 31. It has roots in the Celtic festival of Samhain and the Christian holy day of All Saints. It is largely a secular celebration but some have expressed strong feelings about perceived religious overtones.

welcome to my blog

Hi, there! My name’s Jesus montoya but you can call me montoya. I’m from concepcion, originally. I live in concepceon , in palito blanco. I’m 16 years old and I study accounting at URBE . My favorite atlete is Ronaldo . I LIKE PIZZA.

I love music , dancing, playing soccer, driving my car (I have a red sport car), surfing the net , studying English, talking on the phone with my friends, pizza , chocolate, my family.

I hate TOMATO, smoking, listening to hip hop, getting up early on the weekend, violence, war, injustice, and washing the dishes.

My dream is to travel around the world, visit the Pyramids in Egypt and The Eiffel Tower in Paris. Of course, I want to graduate from ACCOUNTING School and be a good ACCOUNTANT. I also want to learn to speak French, and Italian. I’d love to work in an important company and buy a house, get married and start a family.

About English, I love to learn new languages. I think English is very important. I also chat on the internet and have friends in many countries. I can write well, but I need to practice more. The most difficult for me is speaking. I need to practice more. I hope I can make a lot of friends and practice speaking in this class...
