This planet is internally active, resulting in a healthy strong magnetosphere. There has been negligible atmospheric loss since the last human that saw this world, and conditions are projected to remain habitable for many millions of years.
The cooling process of the terraforming event from the first colonisation of this planet, began long before Guy's time, continued for the first few thousand years after the introduction of cats. It trapped much of the sea algae (that had bloomed in the absence of animals to eat it) under the sea part of the North ice cap, and black spruce forest vegetation under the advancing land ice. This coolant, not being renewed without humans or technology, was depleted within a tens of thousands of years after the disappearance of the ancient colony humans. This caused a reverse in the ice's advancement. As the ice melted it released methane, sulphurous gases and other products of vegetation decomposition. Much of the vegetation only began to decompose when it thawed, resulting in a further gradual release of these gases. This coupled with the already effectively high carbon dioxide concentrations resulted in abrupt climate fluctuations that kept certain species populations from recovering expansively.
Global temperatures rose by 6 degrees. Climate biomes moved latitude and the equatorial rainforests hid up in the cooler mountains, barely hanging on. Catland and Cardiva become mostly hot desert as a result.

Summary of current life:
There was thus a very early evolutionary push towards coping with higher temperatures, especially in tropical regions but even in warm temperate regions summers became difficult to bear. Black spruce became especially restricted to the polar regions and high in the mountains of warmer areas. Norpolarica has become largely black spruce taiga forest with arctic mosses and lichens surviving only in the polar mountains and a small area at the furthest North.
Another early evolutionary consequence common to all forms of life were adjustments to breeding seasons. This was due to the planet's slower orbit around it's star, giving the year over an extra month compared to an Earth year. For a lot of animals this meant multiple reproductive cycles in a season, much like many plants. Some took advantage of extended growing seasons to produce more robust offspring with higher winter survivability, particularly true for more solitary cats, instead of trying to produce as many as possible. As winters were harsh, the extended summers made for a good fattening up time.
However, in some parts of the world the summers didn't offer a boon but were harsh in their own right, with droughts and famines that make those of Earth look tame. Some areas turned into hyper deserts, locations where conditions are so extreme in seasonal variation that no life has evolved yet to be able to exist there for more than a short period of the year. The equator as well as large desert areas have become a dead zone. Extreme year-round heat kills all but a few microbial lifeforms. In the tropics life is more abundant in the water, but with low nutrients from land and the water it's still not that abundant.
Areas close to sea level are hottest, and mountains are survivable oases between the hot lowlands. Hevea brasiliensis, the rubber tree that was around during the cat's colonization, hangs on in Western mountain cloud forests only. Cloud forests have become a very fringe habitat found only in the highest elevations where temperatures are much lower as a thin green line before the mountains peak. The trees here are weak and frequently fall on slipping and crumbling soil. Young or bonsai'd trees dominate as they never get to grow old or big. Only the wind howls through them, there is an absence of animals here. These trees are evolving towards faster reproduction and earlier maturity, and by 100,000 years many rubber "trees" are naturally inclined towards shorter, shrubbier growth, even if ideal conditions were presented for them to grow into trees.
