Explanation:

Geo Engineering

• Climate engineering aka geoengineering is the deliberate and large-scale intervention in the Earth’s climate system, usually with the aim of mitigating the adverse effects of global warming.

Following are the few Geo-Engineering techniques

• Solar Radiation Management (SRM) - It refers to offsetting the warming effect of greenhouse gases by reflecting more solar radiation (sunlight) back into space.
• Carbon Dioxide Removal (CDR) - It refers to removing carbon dioxide gas (CO2) from the atmosphere and sequestering it for long periods of time.
• LOHAFEX - is an ocean iron fertilization experiment to see if iron can cause algal bloom and trap carbon dioxide from the atmosphere.
• It is jointly planned by the Council of Scientific and Industrial Research (CSIR) in India and the Helmholtz Foundation in Germany.

Hence both statements are correct.
