A recent speech by CIA director John O. Brennan at the Council on Foreign Relations mentioned geoengineering, specifically stratospheric aerosol injection.
Claim:
• CIA director John O. Brennan at the Council admits geoengineering in the form of stratospheric aerosol injection (SAI) is taking place, ie "chemtrails".

Rebuttal:
• Nowhere in his speech is there an "admission" that a SAI program is already taking place. The part where Brennan mentions geoengineering is just one example out of several, not-often-mentioned issues that CIA monitors for potential (future) elements of instability in the world. A SAI program, if ever implemented, could generate conflicts and security threats if misused. It's CIA's job to consider all types of concepts for potential future problems and threats, including science oriented concepts.
Reading the whole transcript [mod note 5 May 2023: link posted by member is no longer available - replaced with Wayback Machine Archive, or see transcript on the CFR site], and the relevant parts, it becomes clear that when Brennan brings up geoengineering, he is talking about future concepts, that may never be put into practice:

It is quite clear that John O. Brennan does not talk about something that is already implemented. He talks about merely suggested technology that might be useful, but not necessarily implemented, in the challenge against abrupt anthropogenic global warming. Brennan also raise the issues with the proposed technology from a security perspective, which is what the CIA deals with every day.
This is nothing new. The goals and the problems of the proposed SAI technology is something that has been openly stated and discussed, both science and political-wise for more than a decade now. Brennan does not provide any new information on the subject.
Some interesting side points:
• Brennan mentions that an SAI program intends to combat global warming "in much the same way that volcanic eruptions do".
• Volcanic eruptions cools the earth by depositing ash and sulfur particles in the air.
• Some have suggested a connection to discredited scientist J. Marving's study on coal fly ash, claims which have been addressed and debunked here, here and here.
• The very term stratospheric aerosol injection indicates that the aerosols should be put into the stratosphere, otherwise the aerosols will cause heating instead of cooling. Common "chemtrail" lore believes that conventional airplanes are doing the "spraying", but conventional airplanes cannot fly in the stratosphere. This strongly suggests that the trails seen behind such airplanes cannot be the product of stratospheric aerosol injection.

add2: It has been pointed out that some commercial flight flies in the lower edge of the stratosphere (stratopause). Most common SAI proposals involve ejection of sulphate aerosols at much higher altitudes than that. For example, in the 2008 repport An overview of geoengineering of climate using stratospheric sulphate aerosols a scenario is explained:

Here is the part where SAI is mentioned. Emphasis (bold font) has been added where there are clear indications how Brennan is talking about something that would be, could be a potential future thing:External Quote:I'll start with the overarching challenge of instability, which continues to grip large sections of the globe.
Global instability is one of the defining issues of our time, and its implications are hard to overstate. As instability spreads, extremists and terrorists are finding sanctuary in ungoverned spaces. Energy supplies are being disrupted. Political reform is suffering as too many governments opt for authoritarian measures at the expense of democratic principles and respect for human rights.

[...]
An SAI program could limit global temperature increases, reducing some risks associated with higher temperatures and providing the world economy additional time to transition from fossil fuels.
[...]
As promising as it may be, moving forward on SAI would raise a number of challenges for our government and for the international community. On the technical side, greenhouse gas emission reductions would still have to accompany SAI to address other climate change effects, such as ocean acidification, because SAI alone would not remove greenhouse gases from the atmosphere.
On the geopolitical side, the technology's potential to alter weather patterns and benefit certain regions at the expense of others could trigger sharp opposition by some nations. Others might seize on SAI's benefits and back away from their commitment to carbon dioxide reductions. And, as with other breakthrough technologies, global norms and standards are lacking to guide the deployment and implementation of SAI.

add2: It has been pointed out that some commercial flight flies in the lower edge of the stratosphere (stratopause). Most common SAI proposals involve ejection of sulphate aerosols at much higher altitudes than that. For example, in the 2008 repport An overview of geoengineering of climate using stratospheric sulphate aerosols a scenario is explained:
15km is 50,000 feet which is much higher than conventional commercial flights go. But the altitude depends on the latitude. Northern latitudes require lower altitudes. The repport also explains (my emphasis):External Quote:In each case injection is assumed to occur uniformly between 15 and 25 km, with the initial plumes distributed throughout this region to avoid hot spots.
So it is important to understand that the proposed methods of SAI is neglecting obvious current delivering limitations when it comes to aircrafts. Commercial type aircrafts doesn't seem to be a viable option in this proposition.External Quote:Our generic platform is a jet-fighter-sized aircraft carrying a payload of 10 metric tons of finely divided aerosol, or an equivalent precursor mass, to be distributed evenly over a 2500 km flight path during an 4-hour flight (while few aircraft are currently capable of sustained flight at stratospheric heights, platform design issues are neglected at this point)
