Earth's Recent Climate Spiral
Explanation: Is our Earth warming? Compared to the past 250 million years, the Earth is currently enduring a
relative cold spell, possibly about four degrees
Celsius below average. Over the past 120 years, though, data indicate that the average global temperature of the Earth has increased by nearly one degree Celsius. The
featured visualization video depicts Earth's recent
global warming in graphic terms. The depicted temperatures are taken from the
Goddard Institute for Space Studies'
Surface Temperature Analysis. Already noticeable by many, Earth's recent warming trend is causing
sea levels to rise,
precipitation patterns to change, and
pole ice to melt. Few now disagree that recent global warming is occurring, and the
Intergovernmental Panel on Climate Change (IPCC) has concluded that we humans have created a warming surge that is
likely to continue. A continuation could impact many local agricultures and even the global economy. Although there seems to be
no simple solutions,
geoengineering projects that might help include
artificial cloud creation to reduce the amount of sunlight heating the Earth's surface.

Very nice visual. Scary also, though.

The solution(s) to the climate emergency, while perhaps not simple, will not consist of technological fixes but in making social and political changes leading to a sustainable green economy, and away from the short-term-profit-driven extractive economy that has led to the current crisis.

It would be more precise, perhaps, to say that the solutions largely depend upon technological fixes, but that those fixes require significant social and political changes to take place.

If we could somehow stop overpopulation and this great increase in the number of humans, many problems can be solved.

I believe the humanity should tax all fossil fuel extraction.
Current UN and national governments are not up to such task.
There is going to be a war on climate crime, against free riding regimes trespassing the fossil tax.
Another war is going to start around nuclear power stations. Some nations and groups will grab plutonium from fuel rods or threaten to blow up a reactor, and they possibly are going to make the nuclear power too costly to use.
Those two wars are going be bad for freedom and democracy but, like pirates or robbers, the climate tricksters are not going to stop life altogether; in the end some pirates will destroy each other, some starve, some get caught and some adopt to rules

The world has gone COMPLETELY insane. We don't even begin to understand the complex workings of the atmosphere and now groups of totally insane and megalomaniac scientists want to terraform the earth without us being able to even assess the consequences.
This would be a criminal act!

We, in Germany, have already done these crazy acts. And now, one of the most industrialized nation on Earth will not only suffer a mega crisis due to crazy "green" ideas and a decrease of energy costs of 700%!!!. The politician went totally insane. The prime minister of the most industrialized region of Germany (where the Mercedes are produced) , recommend us to use a washcloth instead of showering to clean our bodies.
Do you really want to get this in the USA????

I believe that there are several contributions to climate change! We
have more homes that need heating;. population increase; a lot
more cars; jets burning fuel; how many tons of rocket fuel used to
place a rocket in orbit! Burning fuel adds tons of water vapor into
the air: the list goes on and on!

Such taxes (and increasingly, fee-and-dividend systems) are already going in place, and will continue to do so. The pricing on fossil fuels is an example of a classic market failure, where externalities make the price and the cost out of balance. Taxes and source fees correct that. It worked in the past with other pollutants, and it's a market-based approach that is popular even with conservative economists.

Taxes and fees depend on the will of those in power to impose them. That will does not yet exists in the U.S. and maybe even less so in the other countries that are the primary burners of fossil fuels. I fear things are going to have to get a lot worse before the needed will materializes.

We already have bills before Congress that have a good chance of passing to implement a fee-and-dividend system. Once people understand them, they are popular, as most people come out economically ahead, with dividends amounting to more than higher energy prices cost people. The direction the country takes in the next few years will decide if such a system is put into place.

My pessimism may be showing, but I think all bets are off if the gov't switches sides later this year and/or in 2024. My fingers remain crossed however!

If that happens, I expect the U.S. will collapse. And it's anybody's guess what the climate consequences of that would be.

I feel a bit sad reading these replies. It's almost as though science has left the building.
I can list the reasons, but it always falls on deaf ears. It will turn into a discussion of politics and not science, which I do not want.
My old colleagues agree with me, and are still actively trying to teach the truth, but I have all but given up hope that anyone actually cares anymore.
Disappointing

There is nothing wrong with discussing the politics of the issue, as that is essential to dealing with it. Report as cranks, however, those who deny the science and let the moderators delete those comments.

I don't understand what the deniers are up in arms about. Most of the proposals to combat climate change make good sense environmentally. What is wrong with reducing pollution and cleaning up the environment. Is that such a bad thing?

The crisis is there not because of "green ideas" but because of conservative politics. Instead of change in power mix and investing in alternatives the conservative parties made Germany completely dependent on Russian gas. Now the pipelines are dry and everyone is in panic. What a surprise. Pretty sure some radicals hoping for your vote have the same answer as everywhere else. Sell the country to the bad guys, take the money and vanish to some tropical island. Well, that's not their answer, but that's their plan.
Prime minister Kretschmann is old. Probably close to senility. Other and younger green politicians had more realistic advice. Just shower faster to save energy. Easy and works.

Thanks - it worked for a while, but then I read the last few posters' comments before this one. We may be doomed after all.

I reported them as cranks, and the moderators did the rest. Opinions can vary on what we should do, but opinions can't rest on falsehoods.

I haven't seen anything here discussing the science of measuring historical temperatures. How does anyone know the temperature in Jan, 1880 by scientific "surface temperature analysis"? Might as well look it up in the newspapers of the day.
Going back a bit farther, how do scientists know that the average temperatures during the ice age were 5-7º C colder than now?
There are a lot of questions about implications of a +/- 1º C change, but I'm concentrating here on the question of the science of measuring historical temperatures. How do the wizards of Goddard and those in universities producing studies actually measure the data on which they base their conclusions?

There are many accurate historical records for temperature in 1880, from all over the globe. Before we had accurate instruments, temperatures are estimated by a large number of proxies- tree rings, pollen, various plant and animal fossils, isotopic analysis of materials... a huge list, and usually multiple proxies are available. So paleotemperature records are considered very reliable in most cases.
