But for John Hemming, a man with much experience of visiting the Amazon peoples, this could not be further from the truth. But how did the surveyer become obsessed with the search that would ultimately be his downfall? And can we perhaps tell a story that steers away from fantasy? Since Europeans first arrived in the New World, there have been stories of a legendary jungle city of gold, sometimes referred to as El Dorado.
Attribution of recent climate change In this article, " climate change " means a change in climate that persists over a sustained period of time. Changes in climate may be due to natural causes, e. Detection does not imply attribution of the detected change to a particular cause.
NASA GISS The graph above shows the average of a set of temperature simulations for the 20th century black linefollowed by projected temperatures for the 21st century based on three greenhouse gas emissions scenarios colored lines.
This projection is relative to global temperatures at the end of the 20th century. Global surface temperature for the past 5.
The lastyears are expanded in the lower half of the figure image credit: Physical impacts of climate change Seven of these indicators would be expected to increase in a warming world and observations show that they are, in fact, increasing. Three would be expected to decrease and they are, in fact, decreasing.
Each of the different colored lines in each panel represents an independently analyzed set of data.
The data come from many different technologies including weather stationssatellitesweather balloonsships and buoys. Some of the graphs show a positive trende.
Other graphs show a negative trend, e. Evidence of warming is also apparent in living biological systems.
With medium confidence see footnote 1IPCC  concluded that human influences had contributed to an increase in heavy precipitation events at the global scale. Projections of future changes in precipitation show overall increases in the global average, but with substantial shifts in where and how precipitation falls.
Extremely hot nights have doubled in frequency. The area in which extremely hot summers are observed, has increased fold. These changes are not explained by natural variability, and attributed by climate scientists to the influence of anthropogenic climate change.
Heat waves with high humidity pose a big risk to human health while heat waves with low humidity lead to dry conditions that increase wildfires. The mortality from extreme heat is larger than the mortality from hurricanes, lightning, tornadoes, floods, and earthquakes together  See also heat wave.
Tropical cyclones At the global scale, the frequency of tropical cyclones will probably decrease or be unchanged.
Some impacts will be beneficial—e. Retreat of glaciers since A map of the change in thickness of mountain glaciers since Thinning in orange and red, thickening in blue.
A map that shows ice concentration on 16 Septemberalong with the extent of the previous record low yellow line and the mid-September median extent black line setting a new record low that was 18 percent smaller than the previous record and nearly 50 percent smaller than the long-term — average.
The cryosphere is made up of areas of the Earth which are covered by snow or ice.
Assuming high growth in greenhouse gas emissions SRES A2some models projected that Arctic sea ice in the summer could largely disappear by the end of the 21st century. Effects of global warming on oceans The role of the oceans in global warming is complex.
The oceans serve as a sink for carbon dioxide, taking up much that would otherwise remain in the atmosphere, but increased levels of CO 2 have led to ocean acidification. Furthermore, as the temperature of the oceans increases, they become less able to absorb excess CO 2.
The ocean have also acted as a sink in absorbing extra heat from the atmosphere. Ongoing effects include rising sea levels due to thermal expansion and melting of glaciers and ice sheets, and warming of the ocean surface, leading to increased temperature stratification. Other possible effects include large-scale changes in ocean circulation.
Ocean acidification This map shows changes in the amount of aragonite dissolved in ocean surface waters between the s and the most recent decade — The uptake of human carbon emissions since the year has led to an average decrease in pH of 0.Welcome Green Monsters!

Nibiru, Planet X, Nemesis, The Destroyer, Wormwood, Hercolubus, Comet Typhon. Is Nibiru real?
Does it take Nibiru 3, years to complete one orbital journey? As you can imagine, the gravitational effects of a sizable planet moving close to the inner solar system would spell big trouble for planet Earth. The fifth planet in our solar system is the biggest planet called Jupiter.
Jupiter is by far the largest planet in our solar system. The mass of Jupiter is times larger than Earth and is twice as big of all of the other planets in our solar system combined.
Jupiter is so large that some people think that it should be considered a star instead of a planet. The Flannan Isles, located in Scotland’s Outer Hebrides, are a set of small and uninhabited rocky islands with a curious history. One of the islands, Eilean Mor, was the setting of a great historical mystery – the disappearance .

Jan 13, · “The disappearance of our planet is still billion years away, but people really should consider the fate of our world and have a realistic understanding of where we are going,” said UW astrophysicist Donald Brownlee.
