The Earth's temperatures and seasons have become inalterably fixed in their present state and that the Earth cannot be hurled off into space or drawn into the sun.
The United Nations said in a report earlier this week that limiting Earth's temperature rise to 1.5 degrees Celsius means making rapid, unprecedented changes in the way people use energy to eat.
MADISON, Wis.-- When the Intergovernmental Panel on Climate Change recently requested a figure for its annual report, to show global temperature trends over the last 10,000 years, the University of Wisconsin-Madison's Zhengyu Liu knew that was going to be a problem.
Q 10:I think that factors that affect thetemperature of the earth can be considered other than changes in CO 2 concentration, but is it unlikely that global freezing will occur due to the amount of water vapor, the amount of methane, the amount of clouds, etc.?
When the Intergovernmental Panel on Climate Change recently requested a figure for its annual report, to show global temperature trends over the last 10,000 years, the University of Wisconsin-Madison's Zhengyu Liu knew that was going to be a problem.
Even the science reporting this paper announced in 1989 that'' climatologists seem to feel that thetemperature of the earth is rising due to the greenhouse effect of carbon dioxide, but it has not yet been proved'' And was skeptical about global warming.
In April 2016, 175 Member States signed the historic Paris Agreement, which sets the stage for ambitious climate action by all to ensure that global temperatures rise no more than 2 degrees Celsius.
He became a leader in the UN Climate Negotiations, calling for a return to 350ppm C02, and asking that a binding treaty be enacted which limits global temperature rise to 2 degrees celsius.
However, if the sun enters a situation without sunspots, such as the Mönder Minimum, from now on it works to lower thetemperature of the Earth, so it is not obvious that the rise in temperature due to the greenhouse effect will be dominant.
Even scientists from the UN have not been enthusiastic in the past, they say today that any plan to retain growth temperature of the planet below 1.5 degrees will rely on a significant jump in the use of nuclear energy.
A new report from the United Nations Intergovernmental Panel on Climate Change released just yesterday warns that we only have about twelve years to take urgent and unprecedented action to prevent a rise in the planet's temperature that would cause irreversible damage.
In politics, the debate over global warming is centered on whether this increase in temperature is due to greenhouse gas emissions or is the result of a natural pattern in the earth's temperature.
The threshold should not be exceeded to avoid aggravating the tendency of natural disasters was estimated to increase by no more than two degrees Celsius in global temperatures, in excess of this figure is not considered possible to limit the effects of climate change, the change that has acquired a rate not much more controllable.
The IPCC report, released every six years, incorporates the key findings from thousands of articles published in scientific journals, concluding with at least 95 percent certainty that human activities have caused most of Earth's temperature rise since 1950, and will continue to do so in the future.
