Answer 1 : According to the NASA and the NOAA 2016 was the hottest year on the record worldwide.
Answer 2 : To get a complete picture of Earth’s temperature, scientists combine measurements from the air above land and the ocean surface collected by ships, buoys and sometimes satellites.
The temperature at each land and ocean station is compared daily to what is ‘normal’ for that location and time, typically the long-term average over a 30-year period. The differences are called an ‘anomalies’ and they help scientists evaluate how temperature is changing over time, a ‘positive’ anomaly means the temperature is warmer than the long-term average, a ‘negative’ anomaly means it’s cooler
Here are four datasets to study global temperature.The UK Met Office Hadley Centre and the University of East Anglia’s Climatic Research Unit jointly produce HadCRUT4 .
In the US, the GISTEMP series comes via the NASA Goddard Institute for Space Sciences (GISS), while the National Oceanic and Atmospheric Administration (NOAA) creates the MLOST record. The Japan Meteorological Agency ( JMA) produces a fourth dataset.
Answer 3 : the NASA Goddard Institute for Space Studies (GISS) in New York City have found that 2006 was the fifth warmest year in the past century
Answer 4 : We can notice about the trend of the top warmest years that an increase in atmospheric greenhouse gases, primarily carbon dioxide from the burning of fossil fuels, continues to drive this long-term warming trend. It is responsible for warming both the atmosphere and the oceans as greenhouse gas concentrations continue to grow. We can notice that it is very hot in the pole,for example we have a faster warming in the Arctic than the rest of the world.

Answer:
United States foreign policy in the Middle East has its roots in the 18th century Barbary Wars in the first years of the United States of America's existence, but became much more expansive in the aftermath of World War II. American policy during the Cold War tried to prevent Soviet Union influence by supporting anti-communist regimes and backing Israel against Soviet-sponsored Arab countries. The U.S. also came to replace the United Kingdom as the main security patron of the Persian Gulf states in the 1960s and 1970s, to ensure a stable flow of Gulf oil.[1] The U.S. has diplomatic relations with all countries in the Middle East except for Iran, whose 1979 revolution against the US-backed reign of Shah Mohammad Reza Pahlavi brought to power a staunchly anti-American regime
Answer:
It is a surprise that the Emancipation Proclamation didn't include African American slaves that lived in the Union territory, but only included those who lived in the Confederate territories.
Explanation:
The Emancipation Proclamation was an Executive Order proclaimed by President Abraham Lincoln in 1862, that entered into force in 1863 declaring slaves in rebellious southern states and territories freed forever.
The Civil War was a struggle for the preservation of the Union after the southern states had separated. Morale in the south was initially high, and people thought they were fighting for his independence and his own way of life; the right of individual states to set their own laws (including the right to keep slaves) was central.
Although initially President Lincoln was hesitant about the complete abolition of slavery, he changed his mind during the course of the war. He was convinced that slavery had to be abolished in order to win the war. This eventually resulted in the abolition of slavery in the rebellious Confederate States of America.
Although slave owners did not tell their slaves about the proclamation, many found out. More and more slaves escaped and revolted, and everywhere the Northern armies appeared the plantations emptied. This proclamation did not cause slaves to be released immediately, but it was a major step forward. The document stated to the whole world that the civil war was meant to put an end to slavery.
