There would be no seasons, far north and south latitudes would have a chilly Spring sort of weather all the time until giving way to permafrost, and the equator would be very hot, more so than now. There would probably be very few migratory animals and trees would not lose their leaves. Animals would probably also not have breeding seasons as often (some would though — a huge rush of young can overwhelm predators who can’t eat enough of them at once), and you could grow crops in a more stable pattern, so there should be earlier human (or whatever) civilization and fewer famines and such.

At present Earth is tilted 23.5 degrees on its axis. This is the primary reason for the seasons. When the Earth is tilted toward the sun the Northern Hemisphere is in the warm season and when the Earth is tilted away from the sun the Northern Hemisphere is in the cool season. Since the Earth revolves at a predictable and relatively steady rate around the sun the cycle repeats itself every year. In the warm season the sun is higher in the sky and it is warmer and in the cool season the sun is lower in the sky and it is cooler.
What if though the Earth was not tilted? In this case the plane of the Earth's poles would always be perpendicular to the sun. The sun would always be just on the horizon 24 hours a day on every day at the poles. Every day would be like what it currently is on the equinox since every location on Earth would have about a 12 hour sunlight days and the noon sun angle would be about the same every day. There would no longer be season as we know them. The temperature and precipitation pattern would not vary much. It would still be warm at the equator and cold at the poles. The most profound impact on temperatures would be at the poles. Instead and dark and frigid temperatures in the winter and warmer and constant sun in the summer, the polar areas would have much more uniform temperatures year round and the sun would always be low on the horizon. Across the Earth it would be like it is in the middle of fall or spring but it would last all year every year. Areas today that have wet, dry, warm and cold seasons would have a fairly constant weather all year whether it be wet, dry, warm and/or cold.
