RCP2. 6 assumes high technological development, and a levelling off of greenhouse emissions by 2050, followed by a return to 2020 levels by 2100. This pathway predicts a rise in global sea surface temperature of 0.8°C by 2050, and 1.2°C by 2100, relative to 1870–1899 temperatures.
There will be more plastic than fish
Rivers of pollution flow into the ocean every day, with little sign of slowing down. Marine animals and birds now regularly eat plastic, and so do humans. It is estimated that by 2050 there could be more plastic in the sea than fish. As the plastic piles up, fish disappear.
Today, just one percent of the planet falls within so-called “barely liveable” hot zones: by 2050, the ratio could rise to almost twenty percent. In 2100, temperatures could rise so high that spending a few hours outside some major capital cities of South Asia and East Asia could be lethal.
Climate shifts like heat waves could restrict the ability of people to work outdoor, and, in extreme cases, put their lives at risk. Under a 2050 climate scenario developed by NASA, continuing growth of the greenhouse emission at today's rate could lead to additional global warming of about 1.5 degrees Celsius by 2050.
Heatwaves will be more frequent and long-lasting, causing droughts, global food shortages, migration, and increased spread of infectious diseases. Moreover, as the polar ice will melt, sea levels will rise substantially, affecting a large number of coastline cities and as many as 275 million of their inhabitants.
2100: Either uninhabitable or beginning to repair
Over the coming two decades, extreme weather is set to disrupt society with increasingly severe bushfires, drought and storms. The good news is by the end of the century, living on Earth could actually be more pleasant than it is today.
There's a 66% chance that the annual global average temperature will hit 1.5 ºC above pre-industrial temperatures at some time in the next five years, according to a World Meteorological Organization report released on 17 May.
While the effects of human activities on Earth's climate to date are irreversible on the timescale of humans alive today, every little bit of avoided future temperature increases results in less warming that would otherwise persist for essentially forever.
The world of 2099 will be unrecognisable from the world of today, but it can be predicted, says a leading visionary. Futuristic structures tower over the landscape. Giant, alien-looking trees light up with dazzling colours amid the hundreds of plant species that grow up their trunks.
There will be "far worse extreme weather events than those we see today. withering droughts, epic floods, deadly hurricanes, and almost inconceivably hot heatwaves; a typical summer day in midlatitude regions like the U.S. will resemble the hottest day we have thus far ever seen." Dr.
The study, published Jan. 30 in Proceedings of the National Academy of Sciences, provides new evidence that global warming is on track to reach 1.5 degrees Celsius (2.7 Fahrenheit) above pre-industrial averages in the early 2030s, regardless of how much greenhouse gas emissions rise or fall in the coming decade.
Scientists say eight years left to avoid worst effects.”
With the UN having confirmed a temperature rise of 1.5°C compared to the pre-industrial era, the climatic, human, food and economic consequences will be unprecedented. On 9 March, NASA published a world map showing the regions of the planet that will no longer be habitable in 30 to 50 years' time due to climate change.
According to a simulation of planetary warming trends, failure to drastically cut greenhouse gas pollution within the next half century could choke Earth's oceans for the next 100,000 years. With warmer temperatures reducing its ability to absorb oxygen, much of the water would become barren and lifeless.
For men, the group expects they will live to be 83 to 86 instead of the government's projection of 80 years average life expectancy in 2050. S. Jay Olshansky, co-author of the report, said a few extra years life might not sound important, but it will cost us socially and financially.
Considerable development along the NSW coast is at risk from inundation and erosion as a result of sea level rise. Around 80% of the NSW population live within 50 km of the coast. The highest risk occurs close to estuaries, where a lot of development has occurred in low-lying areas.
Based on known risks, the really cataclysmic ones, those that might exterminate us as a species, are fairly rare. Based on what we know today, it would be very unlikely that we wouldn't be around in the year 3000. There certainly would be bad times, but some of us would get through it. That leaves unknown risks.
By 1014 (100 trillion) years from now, star formation will end, leaving all stellar objects in the form of degenerate remnants. If protons do not decay, stellar-mass objects will disappear more slowly, making this era last longer.
Just as our planet existed for over 4 billion years before humans appeared, it will last for another 4 billion to 5 billion years, long after it becomes uninhabitable for humans.
India will overtake China as the most populated country on Earth. Nigeria will overtake the US as the third most populous country in the world. The fastest-growing demographic will be the elderly: 65+ people will hit one billion by 2030. We will need to figure out ways of how to accommodate 100+ people at work.
Yes, the vast majority of actively publishing climate scientists – 97 percent – agree that humans are causing global warming and climate change.
Scientists warned that human-induced climate change is warming the planet to the point where it is causing irreversible damage in some parts of the world. The report was released by the United Nations Intergovernmental Panel on Climate Change.
The planetary change that accompanied that warming is mind-boggling: 12,000 years ago, most of North America was 36 degrees colder than it is today, largely because of the retreating ice sheets.
The next ~7 years is humanity's best window to enact bold, transformational changes in our global economy to avoid raising global temperature above 1.5ºC, a point of no return that science tells us is likely to make the worst climate impacts inevitable.
In a 3-degrees-warmer world, the coastlines of today will largely be gone, endlessly reduced over the coming centuries by rising seas. By the end of 2100, sea levels are expected to rise by about 2 feet on average.
