Earth - like planet: its radius is 1.2 to 2.5 times that of
Earth; its mass is 3.1 to 4.3 times greater; and, crucially, its orbit lies within its star's «Goldilocks zone», which means its
surface temperature is neither too hot nor too cold for liquid water - and therefore potentially life - to exist on its

in the OU Mars Simulation Chamber — specialised equipment, which is able to simulate the atmospheric conditions on Mars — reveal that Mars» thin atmosphere (about 7 mbar — compared to 1,000 mbar on
Earth) combined with periods of relatively warm
surface temperatures causes water flowing on the
surface to violently boil.

«Human influence is so dominant now,» Baker asserts, «that whatever is going to go on
in the tropics has much less to do with sea

earth's orbital parameters and much more to do with deforestation, increasing atmospheric carbon dioxide and global warming.»
In the new study, researchers placed tiny particles of silicon carbide (one represented by the group of tan molecules in this artist's concept) covered with graphite (hexagonal networks of gray atoms) in a vacuum chamber that duplicated the deep - space conditions surrounding many stars (temperatures between 900 and 1500 kelvins and pressures less than one - billionth that found at Earth's surface

Again, Monckton must surely know full well that for the last 25 - 30 years satellite

Earth is water... it's difficult to put weather stations on top of ice sheets etc.!)
The oceans are heating up: Not only was
Earth's
temperature record warm

In other words, any other viable alternative scheme to geoengineering must stop

If you look at the recent data where we have particularly good satellite measurements of what the Sun is doing, there is no increasing trend
