Will climate change be irreversible by 2030?
Without increased and urgent mitigation ambition in the coming years, leading to a sharp decline in greenhouse gas emissions by 2030 , global warming will surpass 1.5°C in the following decades, leading to irreversible loss of the most fragile ecosystems, and …
It could take as long as 1,000 years after a complete halt of greenhouse gas emissions for environmental measures like sea level and ocean surface temperature to return to pre-industrial levels [source: NOAA]. In addition, other factors besides greenhouse gas emissions can contribute to global warming.
The severity of damaging human-induced climate change depends not only on the magnitude of the change but also on the potential for irreversibility. This paper shows that the climate change that takes place due to increases in carbon dioxide concentration is largely irreversible for 1,000 years after emissions stop.
Since 1880, average global temperatures have increased by about 1 degrees Celsius (1.7° degrees Fahrenheit). Global temperature is projected to warm by about 1.5 degrees Celsius (2.7° degrees Fahrenheit) by 2050 and 2-4 degrees Celsius (3.6-7.2 degrees Fahrenheit) by 2100.
Global average temperatures have risen and weather extremes have already seen an uptick, so the short answer to whether it's too late to stop climate change is: yes.
With human-made climate change continuing, there's a 48% chance that the globe will reach a yearly average of 1.5 degrees Celsius (2.7 degrees Fahrenheit) above pre-industrial levels of the late 1800s at least once between now and 2026, a bright red signal in climate change negotiations and science, a team of 11 ...
The upshot: Earth has at least 1.5 billion years left to support life, the researchers report this month in Geophysical Research Letters.
The risk that global warming could lead to human extinction is “dangerously under explored”, climate scientists have warned. As the globe heats up and emissions continue to rise, a team of international researchers has urged governments to start paying attention to “worst case scenario” outcomes.
The panel found that humans would suffer and, for the most part, adapt and survive. Not so the millions of species with which we share the planet. Under likely warming scenarios, virtually all the globe's coral reefs (which feed and otherwise benefit a billion people) will be gone.
Greenhouse gas concentrations and global temperatures will not increase indefinitely — today's carbon dioxide buildup and warming trend must eventually top out and then reverse as the atmosphere gradually recovers.

By 2030, almost all countries will experience “extreme hot” weather every other year due mainly to greenhouse gas pollution by a handful of big emitters, according to a paper published Thursday by Communications Earth & Environment, reinforcing forecasts that the coming year will be one of the hottest on record.
Seven billion people will live in urban areas by 2050; vastly outnumbering rural people. There will be more senior citizens than young people (between the ages of 12 and 17) and children (people under the age of 12).
Without major action to reduce emissions, global temperature is on track to rise by 2.5 °C to 4.5 °C (4.5 °F to 8 °F) by 2100, according to the latest estimates.
An asteroid, named "2019 PDC", was discovered that will come dangerously close to the earth 8 years from now, on April 29, 2027. The space rock is between 330 and 1000 feet in size, somewhere in between the length of 6.5 school buses to the height of two Washington Monuments stacked on top of each other.
Earth could continue to host life for at least another 1.75 billion years, as long as nuclear holocaust, an errant asteroid or some other disaster doesn't intervene, a new study calculates. But even without such dramatic doomsday scenarios, astronomical forces will eventually render the planet uninhabitable.
It's the year 2028, and the European Space Agency has been carefully monitoring a worrying situation: an enormous asteroid is en route to strike Earth, although the exact point of impact is not yet clear.
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.
Yes, almost certainly, but the factors that determine the outcome are so immensely complex that our blunt and instrumental efforts are almost meaningless. The only thing that makes a difference is the combined impact of all individual animals including humans.
A theoretical study suggested the maximum human lifespan to be around 125 years using a modified stretched exponential function for human survival curves.
How close are we to extinction?
Study finds that three-quarters of Earth's species could vanish within 300 years. Earth's creatures are on the brink of a sixth mass extinction, comparable to the one that wiped out the dinosaurs.
But even if that common ancestor still existed, the fact that evolution is the result of both random mutation and a process of natural selection imposed by environmental conditions, means it's highly unlikely that it would ever retrace its steps in quite the same way.

- Over-harvesting of fish, trees, and other organisms. ...
- Global climate change, largely due to the burning of fossil fuels. ...
- Pollution, which adds chemicals, heat, and noise to the environment beyond its capacity to absorb them.
Michigan, says globalization expert. A new book examining the forces shaping the future of global migration forecasts Michigan as the best place in the world to live in 2050.
According to reports, there have been five major incidents where humans came close to extinction. Around 75,000 years ago, the Toba volcano in Indonesia erupted.
Sacramento, California is the best place to live for climate change in 2022. 60% of the top 10 places to live in the U.S. for climate change are in California.
The upshot: Earth has at least 1.5 billion years left to support life, the researchers report this month in Geophysical Research Letters.
This formalises its 2030 emission reduction target. The Climate Council welcomes Labor's 43 percent emissions reduction on 2005 levels target by 2030. But it has urged the Parliament to fast track policies to rapidly reduce emissions this decade.

Earth Will Continue to Warm and the Effects Will Be Profound
The potential future effects of global climate change include more frequent wildfires, longer periods of drought in some regions, and an increase in the duration and intensity of tropical storms.
What species will dominate after humans?
Humans have certainly had a profound effect on their environment, but our current claim to dominance is based on criteria that we have chosen ourselves. Ants outnumber us, trees outlive us, fungi outweigh us. Bacteria win on all of these counts at once.
But even without such dramatic doomsday scenarios, astronomical forces will eventually render the planet uninhabitable. Somewhere between 1.75 billion and 3.25 billion years from now, Earth will travel out of the solar system's habitable zone and into the "hot zone," new research indicates.
The report warns that, by 2040, global temperatures are expected to rise 1.5 degrees Celsius above pre-industrial levels, meaning that most people alive today will see the dramatic effects of climate change within their lifetime.
By 2050, outdoor air pollution particulate matter and ground-level ozone is projected to become the top cause of environmentally related deaths worldwide. A study showed that with no change in emissions by 2050, 1,126,000 premature mortalities are expected each year due to ozone8.
The 2030 Agenda is universal, transformative and rights-based. It is an ambitious plan of action for countries, the UN system, and all other actors. The Agenda is the most comprehensive blueprint to date for eliminating extreme poverty, reducing inequality, and protecting the planet.
1. Extreme Weather — Heatwaves. Summers will warm up by up to 3˚C while winters will see warming of up to 10˚C in different parts of the world. It is estimated that about 14% of the world population will be exposed to an extreme heatwave once in 5 years.
A study published in the journal Nature indicates that by 2047, Earth will reach the point of "climate departure," a benchmark meaning that on average the coldest years will be warmer than the hottest years previously on record in a given time frame, Bloomberg reports.
IN LIGHT OF THIS URGENCY, THE UNITED STATES HAS SET A GOAL OF NET-ZERO GREENHOUSE GAS EMISSIONS BY NO LATER THAN 2050. observed warming of 1.0⁰C, but emissions of cooling aerosols have counteracted some of that warming. THIS U.S. NET-ZERO 2050 GOAL IS AMBITIOUS.
