When was the last Ice Age on earth:

1. between 100,000 years ago and 10,000 years ago
2. between one million years ago and 150,000 years ago
3. there was no ice age on earth recently — the last one was about 700 million years ago

When did most of the ice from the last ice age melted:

1. between 12,000 and 10,000 years ago
2. between 160,000 and 150,000 years ago
3. there was no big melt sice there was no ice age

how much did the sea level rise with the melting of the last ice age:

1. 1 millimete
2. 2 metres
3. more than 100 metres
4. the sea level fell since there was no ice age

how much is the current rate of sea level rise:

1. nil
2. 1 millimetre per decade
3. 1.8 millimetre per year
4. the sea level is falling

When was the last period when there was no ice on earth:

1. 120 million years ago (no ice on both poles)
2. 12 million years (no ice in the arctic sea)

what was the sea level approximately 120 million years ago:

1. 2 metres above present
2. possibly 75 metres above present
3. possibly 250 metres above present by 80 million years ago
4. lower than present.

Ocean nourishment

Billions of iron filings are deposited in the ocean to stimulate a phytoplankton bloom. The aim is to enhance biological productivity to remove carbon dioxide from the atmosphere. Many experiments have been conducted, including fertilisation of 900 square kilometers (350 sq miles) of the Atlantic. Results so far are disappointing.

Space mirrors

Giant "mirrors", made of wire mesh, could be sent into in orbit to deflect sunlight back into space. But the scale needed, the expense and the potential unintended consequences are so great that it is widely considered unrealistic. In the same league as the idea to mine the moon to create a shielding cloud of dust.

Cloud whitening

The idea is to increase the water content in low clouds by spraying sea water at them. This makes them reflect more sunlight. It would be pretty harmless, and cheap but would have to be done on an immense scale to have any global effect. Backed by Bill Gates.

Artificial trees

Proposed by climate scientist Wallace Broecker who imagines 60m artificial "trees" dotted around the world, "scrubbing" the air by capturing CO2 in a filter and then storing it underground. The trees could remove more carbon dioxide than an equivalent-sized real tree.

Albedo changes

Painting roofs and roads white, covering deserts in reflective plastic sheeting, dropping pale-coloured litter into the ocean and genetically engineering crops to be paler have all been proposed to reflect sunlight back into space.

Carbon capture and storage (CCS)

Carbon dioxide is collected from coal or other fossil fuel power plants and is then pumped underground. Works in principle but it is expensive and increases the fuel needs of a coal-fired plant by 25%-40%. More than 40 plants have been built with many others planned.

Gus: let's also mention CO2 emission reduction, methane emission reduction, stabilisation of human population on the planet, usage of carbon-neutral (or carbon-less) energy sources, thriftiness, recycling, minimisation of obsolescence by making better smarter products, rewriting of the capitalism code (codified greed and advertising of want) to include cost of damage to the environment and the protection of nature.

Today has been the hottest September 30 for more than 100 years - with records being broken across the country.

In Cambridge, a temperature of 29.2C (84.6F) was recorded mid-afternoon, smashing the previous high of 27.8C (82F) recorded in Maidenhead, Berkshire, on the same day in 1908.

Aisling Creevey, a forecaster with MeteoGroup, the weather division of the Press Association, said: "Records have been broken for September 30 in a few places in the UK."

Those jetting off on holidays in search of sunshine may well find temperatures at home are just as good as those abroad.

Heathrow Airport can usually expect to see temperatures around 19C (66.2F)in September, and 15C (59F) in October.

Ms Creevey said: "We would expect the temperature for the last day of September to fall somewhere between these figures.

"But 28C (82.4F) has been recorded there today - 10C (50F) above average."

In Spain, temperatures of 29C (84.2F) have also been seen, while in Greece they ranged between 26C (78.8F) and 28C (82.4F).

There is now speculation that tomorrow could see the hottest October day ever recorded. The current record, set in March, Cambridgeshire, on October 1, 1985, is 29.4C (85F).

Ms Creevey said: "We're expecting another warm day tomorrow. It should be 29C (84.2F) in London."

Forecasters expect the weather to remain warm until the beginning of next week.
